NASA’s Artemis missions aim to establish a sustained lunar presence on and around the Moon. Communications and navigation technologies will be critical to enabling the safety, science, and operations of our astronauts and missions.NASA Solicitation Number: NNH16ZCQ001K-1_Appendix-Q-LUTNOMS July 8, 2024 – Solicitation Released Solicitation Overview NASA’s long-term vision to provide for a resilient space and ground communications and navigation infrastructure in which space mission users can seamlessly “roam” between an array of space-based and ground-based networks has been bolstered by innovative studies delivered by industry through the Next Space Technologies for Exploration (NextSTEP) – 2 Omnibus Broad Agency Announcement vehicle. Initially, NASA seeks to create an interoperable architecture composed of a mixture of existing NASA assets and commercial networks and services. In the long-term, this will allow for a smooth transition to fully commercialized communications services for near-Earth users. The overarching goal is to create a reliable, robust, and cost-effective set of commercial services in which NASA is one of many customers. NASA’s Commercialization, Innovation, and Synergies (CIS) Office has released a solicitation notice under the Next Space Technologies for Exploration Partnerships-2 (Next STEP-2) Broad Agency Announcement (BAA) to seek industry insights, innovative guidance, and demonstrations in the following two (2) Study Areas: Lunar User Terminals Network Orchestration and Management System (NOMS) To support lunar surface operations, NASA is seeking state-of-the-art industry studies, system development, and demonstrations for a dual-purpose navigation and communication lunar surface user terminal. The terminal must meet technical requirements provided by the government to support lunar surface exploration plans and ensure interoperability with developed LunaNet and Lunar Communications Relay and Navigation System (LCRNS) standards. The requirements will be split into separate LunaNet Augmented Forward Signal (AFS) navigation receiver and communications transceiver capabilities. However, the development of a combined communications and position, navigation, and timing (CPNT) system capable of meeting the full suite of requirements is desired. Additionally, NASA is seeking innovative industry studies and demonstrations on advanced Network Orchestration and Management Systems (NOMS) that effectively address NASA technical requirements aimed at controlling and interfacing with a globally distributed network of Satellite Ground Systems currently supporting the Near Space Network (NSN). The resulting studies will ensure advancement of NASA’s development of space communication and exploration technologies, capabilities, and concepts. View the full article

This image of the Mammoth Lakes 2 drill fines and drill ***** was taken from about 25 centimeters (about 10 inches) above the surface. Earth planning date: Friday, July 5, 2024 Curiosity will drive away from the Mammoth Lakes drill location on the second sol of this three-sol weekend plan, but before she does, the team will take the opportunity for one last chance at contact science in this interesting region of the Gediz Vallis ********. The team have noticed distinct troughs surrounding many of the bright-toned, pitted blocks in this area and have been wanting to get closer imaging with MAHLI before driving away. We were unable to do this with powdered Mammoth Lakes still in the drill stem but, having dumped any remaining material in the previous plan, Curiosity is free to use her arm again for contact science, and hence the MAHLI camera. We will take images from about 30 centimeters (about 12 inches) away from the block (“Glacier Notch”) with MAHLI. Unfortunately, “Glacier Notch” was too close to the rover to be able to fit the turret in for APXS to examine the chemistry, so we had to choose a different target: “Lake Ediza” is an example of gray material that rims the Mammoth Lakes drill block. We also have one last chance for ChemCam and Mastcam in this immediate area. We will acquire ChemCam passive spectra of the Mammoth Lakes powdered material surrounding the drill ***** (we collected APXS data and MAHLI images of the drill fines in the previous plan) and LIBS on a darker-toned target, “Zumwalt Meadow.” These targets will be documented by Mastcam. The long-distance imaging capabilities of ChemCam will also be utilized to examine nearby ridge and trough-like forms. There are also a slew of atmospheric/environmental observations planned. Before we drive away, we will take advantage of being parked in the same spot while drilling to monitor any changes in the immediate environment by re-imaging a couple of areas previously captured on multiple occasions by Mastcam. Other atmospheric observations include a Navcam line-of-sight mosaic, Navcam dust ******, zenith, and suprahorizon movies, a ChemCam passive sky, and Mastcam taus. After the drive, MARDI will image the terrain beneath the wheels and ChemCam will autonomously select a target to analyze with LIBS. Standard REMS, DAN and RAD activities round out the plan. The team are looking forward to a new workspace when we return for planning on Monday, and continued investigation of the Gediz Vallis ********.

Mitigating human risk and returning Artemis II astronauts safely to Earth is paramount as NASA prepares for its first crewed mission aboard the Space Launch System to the Moon in more than 50 years. Engineers use the Marshall facility to simulate launch conditions for testing SLS hardware, the TPS (thermal protection system), and other materials in a Mach 4 environment – four times the speed of sound. The Hot Gas Facility at NASA’s Marshall Space Flight Center is a unique, world-class gaseous hydrogen/air combustion-driven wind tunnel used primarily for Thermal Protection System testing and aerothermal definition. NASA “At NASA, we live on the idea of ‘test like you fly,’” said Malik Thompson, Commercial Crew TPS subsystem manager. “It’s very difficult to replicate the entirety of space and the environment that gets you there. It’s a unique capability – and the only one in the entire world.” The current Hot Gas Facility has been in service for 37-plus years and has completed more than 27,000 hot firings. It was built to develop, characterize, and qualify TPS materials for flight vehicles, but has proven to be invaluable for addressing in-flight anomalies and performing material and instrumentation studies. It has qualified materials for NASA crewed and uncrewed flight vehicles, as well as for Department of Defense and commercial vehicles. During tests, combustion products are expanded from the combustion chamber through a two-dimensional nozzle into a 16×16 inch test section. A Mach 4 flow environment is induced, along with heating rates up to 3,000 degrees Fahrenheit. It can induce convective and radiant heating simultaneously to accurately simulate flight conditions during ascent. The facility has 512 channels of instrumentation to support a variety of engineering measurements and test scenarios. The facility’s flexibility, and its innovative and experienced crew members, means NASA can accomplish testing more quickly and at considerably less cost when compared to large national test facilities. “Conditions and configurations can be adjusted during a test program to address issues as they arise,” said Greg Vinyard, a Marshall engineer who has worked 38 years at the facility. “This flexibility is valuable for small and large-scale research and development programs. The experienced crew adds to the unique capability, working with customers to provide innovative methods to address the requirements of a test program and maximize the results of the testing.” The facility served as the benchmark for the recession characteristics of space shuttle TPS materials and historically has been “the acid test” – if a material survives the Hot Gas Facility environments, the material will survive flight environments. “Freeing a launch vehicle from the surface of Earth is a huge part of space travel, and you need a lot of acceleration speed to escape gravity,” Thompson said. “It’s something you can’t replicate very easily, but the Hot Gas Facility is so much more than a wind tunnel. The high temperature aspect of testing is very important, and the ability to adjust to fit various launch environments.” The facility’s legacy stretches from the Space Shuttle Program to the International Space Station and now Artemis. Artemis II will carry a crew of four around the Moon to confirm systems operate as designed in the deep space environment. The mission will pave the way to way for lunar surface missions, establish long-term lunar science and exploration capabilities, and inspire the next generation of explorers. The Hot Gas Facility validates critical safety measures for the mission, with testing primarily focused on TPS, spray-on foam insulation, and other materials protecting the SLS (Space Launch System) rocket and the Orion spacecraft. “These are crewed missions,” Thompson said. “Mitigating and understanding risks as much as possible is part of the job. Getting these materials in these environments to make sure they are capable of withstanding and still performing is important.” A prime example of the facility’s capability was 2022 testing for the Human Exploration Development and Operations Office for the Commercial Crew Program. A ****** test series with SpaceX, proposed by Thompson, was a seven-month campaign with launch vehicles that would carry astronauts to and from the space station, with 185 test runs. “We set up a test campaign that would allow us to find a way to test components and materials for multiple flights and have a safe vehicle for a crewed flight,” Thompson said. Hot Gas Facility, where their motto is “how hot and how long,” has operated at Marshall since 1971, evolving over the years to incorporate lessons learned from previous designs. “Testing here focuses on improving TPS design to make it safer for astronauts,” Thompson said. “Astronauts do the hard work in space. The testing we do on the ground informs the decisions we make to get them there safely. Capabilities like those we have at the Hot Gas Facility are our primary tool for preparing for the unknown.” Smith, a Media Fusion employee and the Marshall Star editor, supports the Marshall Office of Communications. › Back to Top NASA Announces Winners of Inaugural Human Lander Challenge NASA’s 2024 Human Lander Challenge (HuLC) Forum brought 12 university teams from across the ******* States to Huntsville, near the agency’s Marshall Space Flight Center, to showcase their innovative concepts for addressing the complex issue of managing lunar dust. The 12 finalists, selected in March 2024, presented their final presentations to a panel of NASA and industry experts from NASA’s Human Landing Systems Program at the HuLC Forum in Huntsville June 25-27. Twelve university teams gathered in Huntsville, near NASA’s Marshall Space Flight Center, June 25-27, to participate in the final round of NASA’s 2024 Human Lander Challenge (HuLC) Forum.NASA/Ken Hall NASA’s lunar exploration campaign Artemis is working to send the first woman, first person of ******, and first international partner astronaut to the Moon and establish long-term lunar science and exploration capabilities. Dust mitigation during landing is one of the key challenges NASA and its Artemis partners will have to address in exploring the lunar South Pole region and establishing a long-term human presence on the Moon. Participants in the 2024 Human Lander Challenge developed proposed systems-level solutions that could be potentially implemented within the next 3-5 years to manage or prevent clouds of dust – called lunar plume surface interaction – that form as a spacecraft touches down on the Moon. NASA announced the University of Michigan team, with their project titled, “ARC-LIGHT: Algorithm for Robust Characterization of Lunar Surface Imaging for Ground Hazards and Trajectory” as the selected overall winner and recipient of a $10,000 award June 27. The University of Illinois, Urbana-Champaign took second place and a $5,000 award with their project, “HINDER: Holistic Integration of Navigational Dynamics for Erosion Reduction,” followed by University of Colorado Boulder for their project, “Lunar Surface Assessment Tool (LSAT): A Simulation of Lunar Dust Dynamics for Risk Analysis,” and a $3,000 award. “Managing and reducing the threat of lunar dust is a formidable challenge to NASA and we are committed to real solutions for our long long-term presence on the Moon’s surface,” said Don Krupp, associate program manager for the HLS Program at Marshall. “A key part of NASA’s mission is to build the next generation of explorers and expand our partnerships across commercial industry and the academic community to advance HLS technologies, concepts, and approaches. The Human Lander Challenge is a great example of our unique partnership with the academic community as they help provide innovative and real solutions to the unique risks and challenges of returning to the Moon.” NASA selected the University of Michigan as the overall winner of NASA’s 2024 Human Lander Challenge (HuLC) Forum.NASA/Ken Hall Two teams received the excellence in systems engineering award: Texas A&M University, “Synthetic Orbital Landing Area for Crater Elimination (SOLACE) Embry-Riddle Aeronautical University, Prescott, “Plume Additive for Reducing Surface Ejecta and Cratering (PARSEC) “The caliber of solutions presented by the finalist teams to address the challenges of lunar-plume surface interaction is truly commendable,” said Esther Lee, HuLC judging panel chair and aerospace engineer at NASA’s Langley Research Center. “Witnessing the development of these concepts is an exciting glimpse into the promising future of aerospace leadership. It’s inspiring to see so many brilliant minds coming together to solve the challenges of lunar landings and exploration. We may all come from different educational backgrounds, but our shared passion for space unites us.” Student and faculty advisor participants had the opportunity to network and interact with NASA and industry subject matter experts who are actively working on NASA’s Human Landing System capabilities giving participants a unique insight to careers and operations that further the Agency’s mission of human space exploration. NASA’s Human Lander Challenge is sponsored by Human Landing System Program and managed by the National Institute of Aerospace.

On a much larger scale, integration of NASA’s powerful SLS (Space Launch System) rocket and the Orion spacecraft for the agency’s Artemis campaign would not be possible without the adapters being built, tested, and refined at NASA’s Marshall Space Flight Center. Six adapters for the next of NASA’s SLS (Space Launch System) rockets for Artemis II through Artemis IV are currently at NASA’s Marshall Space Flight Center. Engineers are analyzing data and applying lessons learned from extensive in-house testing and the successful uncrewed Artemis I test flight to improve future iterations of the rocket.NASA/Sam Lott Marshall is currently home to six adapters designed to connect SLS’s upper stages with the core stages and propulsion systems for future Artemis flights to the Moon. The first three Artemis flights use the SLS Block 1 rocket variant, which can send more than 27 metric tons (59,500 pounds) to the Moon in a single launch with the assistance of the interim cryogenic propulsion stage. The propulsion stage is sandwiched between two adapters: the launch vehicle stage adapter and the Orion stage adapter. The cone-shaped launch vehicle stage adapter provides structural strength and protects the rocket’s flight computers and other delicate systems from acoustic, thermal, and vibration effects. “The inside of the launch vehicle stage adapter for the SLS rocket uses orthogrid machining – also known as waffle pattern machining,” said Keith Higginbotham, launch vehicle stage adapter hardware manager supporting the SLS Spacecraft/Payload Integration & Evolution Office at Marshall. “The aluminum alloy plus the grid pattern is lightweight but also very strong.” Following the first flight of SLS with Artemis I, technicians adjusted their approach to assembling the launch vehicle stage adapter by introducing the use of a rounding tool to ensure that no unintended forces are placed on the hardware.NASA/Sam Lott The launch vehicle stage adapter for Artemis II is at Marshall and ready for shipment to NASA’s Kennedy Space Center, while engineering teams are completing outfitting and integration work on the launch vehicle stage adapter for Artemis III. These cone-shaped adapters differ from their Artemis I counterpart, featuring additional avionics protection for crew safety. Just a few buildings over, the Orion stage adapter for Artemis II, with its unique docking target that mimics the target on the interim cryogenic propulsion stage to test Orion’s handling during the piloting demonstration test, is in final outfitting prior to shipment to Kennedy for launch preparations. The five-foot-tall, ring-shaped adapter is small but mighty: in addition to having space to accommodate small secondary payloads, it contains a diaphragm that acts as a barrier to prevent gases generated during launch from entering Orion. The Artemis III Orion stage adapter’s major structure is complete and its avionics unit and diaphragm will be installed later this year. The Orion stage adapter is complete at Marshall, including welding, painting, and installation of the secondary payload brackets, cables, and avionics unit. The adapter is protected by a special conductive paint that prevents electric arcing in space. NASA astronauts Reid Wiseman and Christina Koch viewed the hardware during a Nov. 27 visit to Marshall.NASA/Charles Beason Beginning with Artemis IV, a new configuration of SLS, the SLS Block 1B, will use the new, more powerful exploration upper stage to enable more ambitious missions to deep space. The new stage requires new adapters. The cone-shaped payload adapter – containing two aluminum rings and eight composite panels made from a graphite epoxy material – will be housed inside the universal stage adapter atop the rocket’s exploration upper stage. The payload adapter test article is being twisted, shaken, and placed under extreme pressure to check its structural strength as part of testing at Marshall. Engineers are making minor changes to the design of the flight article, such as the removal of certain vent holes, based on the latest analyses. SLS Block 1B’s payload adapter is an evolution from the Orion stage adapter used in the Block 1 configuration, but each will be unique and customized to fit individual mission needs. “Both the Orion stage adapter and the payload adapter are being assembled in the same room at Marshall,” said Brent Gaddes, lead for the Orion stage adapter in the Spacecraft/Payload Integration & Evolution Office at Marshall. “So, there’s a lot of cross-pollination between teams.”NASA/Sam Lott The sixth adapter at Marshall is a development test article of the universal stage adapter, which will be the largest composite structure from human spaceflight missions ever flown at 27.5 feet in diameter and 32 feet long. It is currently undergoing modal and structural testing to ensure it is light, strong, and ready to connect SLS Block 1B’s exploration upper stage to Orion. “Every pound of structure is equal to a pound of payload,” says Tom Krivanek, universal stage adapter sub-element project manager at NASA’s Glenn Research Center. Glenn manages the adapter for the agency. “That’s why it’s so valuable that the universal stage adapter be as light as possible. The universal stage adapter separates after the translunar insertion, so NASA will need to demonstrate the ability to separate cleanly in orbit in very cold conditions.” With its multipurpose testing equipment, innovative manufacturing processes, and large-scale integration facilities, Marshall facilities and capabilities enable teams to process composite hardware elements for multiple Artemis missions in parallel, providing for cost and schedule savings. Unlike the flight hardware, the universal stage adapter’s development test article has flaws intentionally included in its design to test if fracture toughness predictions are correct. Technicians are incorporating changes for the next test article, including alterations to the vehicle damping system mitigating vibrations on the launch pad.NASA/Brandon Hancock Lessons learned from testing and manufacturing hardware for the first three SLS flights in the Block 1 configuration have aided in designing and integrating the SLS Block 1B configuration. Both adapters for the SLS Block 1 are manufactured using friction stir welding in Marshall’s Materials and Processes Laboratory, a process that very reliably produces materials that are typically free of flaws. Pioneering techniques such as determinant assembly and digital tooling ensure an efficient and uniform manufacturing process and save NASA and its partners money and time when building Block 1B’s payload adapter. Structured light scanning maps each panel and ring individually to create a digital model informing technicians where holes should be drilled. “Once the holes are put in with a hand drill located by structured light, it’s simply a matter of holding the pieces together and dropping fasteners in place,” Gaddes said. “It’s kind of like an erector set.” From erector sets to the Moon and beyond – the principles of engineering are the same no matter what you are building. › Back to Top Juno Gets a Close-Up Look at Lava Lakes on Jupiter’s Moon Io New findings from NASA’s Juno probe provide a fuller picture of how widespread the lava lakes are on Jupiter’s moon Io and include first-time insights into the volcanic processes at work there. These results come courtesy of Juno’s Jovian Infrared Auroral Mapper (JIRAM) instrument, contributed by the Italian Space Agency, which “sees” in infrared light. Researchers published a paper on Juno’s most recent volcanic discoveries on June 20 in the journal Nature Communications Earth and Environment. The JunoCam instrument aboard NASA’s Juno spacecraft captured two volcanic plumes rising above the horizon of Jupiter’s moon Io. The image was taken Feb. 3 from a distance of about 2,400 miles.Image data: NASA/JPL-Caltech/SwRI/MSSS, Image processing by Andrea Luck (CC BY) Io has intrigued the astronomers since 1610, when Galileo Galilei first discovered the Jovian moon, which is slightly larger than Earth’s Moon. Some 369 years later, NASA’s Voyager 1 spacecraft captured a volcanic eruption on the moon. Subsequent missions to Jupiter, with more Io flybys, discovered additional plumes – along with lava lakes. Scientists now believe Io, which is stretched and squeezed like an accordion by neighboring moons and massive Jupiter itself, is the most volcanically active world in the solar system. But while there are many theories on the types of volcanic eruptions across the surface of the moon, little supporting data exists. In both May and October 2023, Juno flew by Io, coming within about 21,700 miles and 8,100 miles, respectively. Among Juno’s instruments getting a good look at the beguiling moon was JIRAM. Designed to capture the infrared light (which is not visible to the human eye) emerging from deep inside Jupiter, JIRAM probes the weather layer down to 30 to 45 miles below the gas giant’s cloud tops. But during Juno’s extended mission, the mission team has also used the instrument to study the moons Io, Europa, Ganymede, and Callisto. The JIRAM Io imagery showed the presence of bright rings surrounding the floors of numerous hot spots. “The high spatial resolution of JIRAM’s infrared images, combined with the favorable position of Juno during the flybys, revealed that the whole surface of Io is covered by lava lakes contained in caldera-like features,” said Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome. “In the region of Io’s surface in which we have the most complete data, we estimate about 3% of it is covered by one of these molten lava lakes.” (A caldera is a large depression formed when a volcano erupts and collapses.) JIRAM’s Io flyby data not only highlights the moon’s abundant lava reserves, but also provides a glimpse of what may be going on below the surface. Infrared images of several Io lava lakes show a thin circle of lava at the border, between the central crust that covers most of the lava lake and the lake’s walls. Recycling of melt is implied by the lack of lava flows on and beyond the rim of the lake, indicating that there is a balance between melt that has erupted into the lava lakes and melt that is circulated back into the subsurface system. Infrared data collected Oct. 15, 2023, by the JIRAM instrument aboard NASA’s Juno shows Chors Patera, a lava lake on Jupiter’s moon Io. The team believes the lake is largely covered by a thick, molten crust, with a hot ring around the edges where lava from Io’s interior is directly exposed to space.NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM/MSSS “We now have an idea of what is the most frequent type of volcanism on Io: enormous lakes of lava where magma goes up and down,” Mura said. “The lava crust is forced to break against the walls of the lake, forming the typical lava ring seen in Hawaiian lava lakes. The walls are likely hundreds of meters high, which explains why magma is generally not observed spilling out of the paterae” – bowl-shaped features created by volcanism – “and moving across the moon’s surface.” JIRAM data suggests that most of the surface of these Io hot spots is composed of a rocky crust that moves up and down cyclically as one contiguous surface due to the central upwelling of magma. In this hypothesis, because the crust touches the lake’s walls, friction keeps it from sliding, causing it to deform and eventually break, exposing lava just below the surface. An alternative hypothesis ******** in play: Magma is welling up in the middle of the lake, spreading out and forming a crust that sinks along the rim of the lake, exposing lava. “We are just starting to wade into the JIRAM results from the close flybys of Io in December 2023 and February 2024,” said Scott Bolton, principal investigator for Juno at the Southwest Research Institute in San Antonio. “The observations show fascinating new information on Io’s volcanic processes. Combining these new results with Juno’s longer-term campaign to monitor and map the volcanoes on Io’s never-before-seen north and south poles, JIRAM is turning out to be one of the most valuable tools to learn how this tortured world works.” Juno ********* its 62nd flyby of Jupiter – which included an Io flyby at an altitude of about 18,175 miles – on June 13. The 63rd flyby of the gas giant is scheduled for July 16. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center for the agency’s Science Mission Directorate.

They hoped the material would hold secrets of the solar system’s past and the prebiotic chemistry that might have led to the origin of life on Earth. An early analysis of the Bennu sample, published June 26 in Meteoritics & Planetary Science, demonstrates this excitement was warranted. A tiny fraction of the asteroid Bennu sample returned by NASA’s OSIRIS-REx mission, shown in microscope images. The top-left pane shows a dark Bennu particle, about a millimeter long, with an outer crust of bright phosphate. The other three panels show progressively zoomed-in views of a fragment of the particle that split off along a bright vein containing phosphate, captured by a scanning electron microscope.From Lauretta & Connolly et al. (2024) Meteoritics & Planetary Science, doi:10.1111/maps.14227. The OSIRIS-REx Sample Analysis Team found that Bennu contains the original ingredients that formed our solar system. The asteroid’s dust is rich in carbon and nitrogen, as well as organic compounds, all of which are essential components for life as we know it. The sample also contains magnesium-sodium phosphate, which was a surprise to the research team, because it wasn’t seen in the remote sensing data collected by the spacecraft at Bennu. Its presence in the sample hints that the asteroid could have splintered off from a long-gone, tiny, primitive ocean world. Analysis of the Bennu sample unveiled intriguing insights into the asteroid’s composition. Dominated by clay minerals, particularly serpentine, the sample mirrors the type of rock found at mid-ocean ridges on Earth, where material from the mantle, the layer beneath Earth’s crust, encounters water. This interaction doesn’t just result in clay formation; it also gives rise to a variety of minerals like carbonates, iron oxides, and iron sulfides. But the most unexpected discovery is the presence of water-soluble phosphates. These compounds are components of biochemistry for all known life on Earth today. While a similar phosphate was found in the asteroid Ryugu sample delivered by JAXA’s (Japan Aerospace Exploration Agency) Hayabusa2 mission in 2020, the magnesium-sodium phosphate detected in the Bennu sample stands out for its purity – that is, the lack of other materials in the mineral – and the size of its grains, unprecedented in any meteorite sample. The finding of magnesium-sodium phosphates in the Bennu sample raises questions about the geochemical processes that concentrated these elements and provides valuable clues about Bennu’s historic conditions. “The presence and state of phosphates, along with other elements and compounds on Bennu, suggest a watery past for the asteroid,” said Dante Lauretta, co-lead author of the paper and principal investigator for OSIRIS-REx at the University of Arizona, Tucson. “Bennu potentially could have once been part of a wetter world. Although, this hypothesis requires further investigation.” “OSIRIS-REx gave us exactly what we hoped: a large pristine asteroid sample rich in nitrogen and carbon from a formerly wet world,” said Jason Dworkin, a co-author on the paper and the OSIRIS-REx project scientist at NASA’s Goddard Space Flight Center. Despite its possible history of interaction with water, Bennu ******** a chemically primitive asteroid, with elemental proportions closely resembling those of the Sun. “The sample we returned is the largest reservoir of unaltered asteroid material on Earth right now,” Lauretta said. This composition offers a glimpse into the early days of our solar system, over 4.5 billion years ago. These rocks have retained their original state, having neither melted nor resolidified since their inception, affirming their ancient origins. The team has confirmed the asteroid is rich in carbon and nitrogen. These elements are crucial in understanding the environments where Bennu’s materials originated and the chemical processes that transformed simple elements into complex molecules, potentially laying the groundwork for life on Earth. “These findings underscore the importance of collecting and studying material from asteroids like Bennu – especially low-density material that would typically ***** up upon entering Earth’s atmosphere,” Lauretta said. “This material holds the key to unraveling the intricate processes of solar system formation and the prebiotic chemistry that could have contributed to life emerging on Earth.” Dozens more labs in the ******* States and around the world will receive portions of the Bennu sample from NASA’s Johnson Space Center in the coming months, and many more scientific papers describing analyses of the Bennu sample are expected in the next few years from the OSIRIS-REx Sample Analysis Team. “The Bennu samples are tantalizingly beautiful extraterrestrial rocks,” said Harold Connolly, co-lead author on the paper and OSIRIS-REx mission sample scientist at Rowan University in Glassboro, New Jersey. “Each week, analysis by the OSIRIS-REx Sample Analysis Team provides new and sometimes surprising findings that are helping place important constraints on the origin and evolution of Earth-like planets.” Launched on Sept. 8, 2016, the OSIRIS-REx spacecraft traveled to near-Earth asteroid Bennu and collected a sample of rocks and dust from the surface. OSIRIS-REx, the first U.S. mission to collect a sample from an asteroid, delivered the sample to Earth on Sept. 24, 2023. NASA’s Goddard Space Flight Center provided overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The university leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provided flight operations. Goddard and KinetX Aerospace were responsible for navigating the OSIRIS-REx spacecraft. Curation for OSIRIS-REx takes place at NASA Johnson. International partnerships on this mission include the OSIRIS-REx Laser Altimeter instrument from CSA (********* Space Agency) and asteroid sample science collaboration with JAXA’s Hayabusa2 mission. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center for the agency’s Science Mission Directorate. › Back to Top Webb Captures Celestial Fireworks Around Forming Star The cosmos seems to come alive with a crackling ********** of pyrotechnics in this new image from NASA’s James Webb Space Telescope. Taken with Webb’s MIRI (Mid-Infrared Instrument), this fiery hourglass marks the scene of a very young object in the process of becoming a star. A central protostar grows in the neck of the hourglass, accumulating material from a thin protoplanetary disk, seen edge-on as a dark line. L1527, shown in this image from NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument), is a molecular cloud that harbors a protostar. It resides about 460 light-years from Earth in the constellation Taurus. The more diffuse blue light and the filamentary structures in the image come from organic compounds known as polycyclic aromatic hydrocarbons (PAHs), while the red at the center of this image is an energized, thick layer of gases and dust that surrounds the protostar. The region in between, which shows up in white, is a mixture of PAHs, ionized gas, and other molecules. This image includes filters representing 7.7 microns light as blue, 12.8 microns light as green, and 18 microns light as red. NASA, ESA, CSA, STScI The protostar, a relatively young object of about 100,000 years, is still surrounded by its parent molecular cloud, or large region of gas and dust. Webb’s previous observation of L1527, with NIRCam (Near-Infrared Camera), allowed us to peer into this region and revealed this molecular cloud and protostar in opaque, vibrant colors. Both NIRCam and MIRI show the effects of outflows, which are emitted in opposite directions along the protostar’s rotation axis as the object consumes gas and dust from the surrounding cloud. These outflows take the form of bow shocks to the surrounding molecular cloud, which appear as filamentary structures throughout. They are also responsible for carving the bright hourglass structure within the molecular cloud as they energize, or excite, the surrounding matter and cause the regions above and below it to glow. This creates an effect reminiscent of fireworks brightening a cloudy night sky. Unlike NIRCam, however, which mostly shows the light that is reflected off dust, MIRI provides a look into how these outflows affect the region’s thickest dust and gases. The areas ******** here in blue, which encompass most of the hourglass, show mostly carbonaceous molecules known as polycyclic aromatic hydrocarbons. The protostar itself and the dense blanket of dust and a mixture of gases that surround it are represented in red. (The sparkler-like red extensions are an artifact of the telescope’s optics). In between, MIRI reveals a white region directly above and below the protostar, which doesn’t show as strongly in the NIRCam view. This region is a mixture of hydrocarbons, ionized neon, and thick dust, which shows that the protostar propels this matter quite far away from it as it messily consumes material from its disk. As the protostar continues to age and release energetic jets, it’ll consume, ********, and push away much of this molecular cloud, and many of the structures we see here will begin to fade. Eventually, once it finishes gathering mass, this impressive display will end, and the star itself will become more apparent, even to our visible-light telescopes. The combination of analyses from both the near-infrared and mid-infrared views reveal the overall behavior of this system, including how the central protostar is affecting the surrounding region. Other stars in Taurus, the star-forming region where L1527 resides, are forming just like this, which could lead to other molecular clouds being disrupted and either preventing new stars from forming or catalyzing their development. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (********* Space Agency) and CSA (********* Space Agency). Several NASA centers contributed to the project, including NASA’s Marshall Space Flight Center. › Back to Top Enhancing Decision-Making with NASA SPoRT: From Earth Science to Action By Paola Pinto During summer months, lightning-related injuries and fatalities rise mainly because of the increase in outdoor activities. Staying informed and cautious is crucial to ensure safety during these times. That is why making timely decisions and preventing potential hazards using tools like the Stoplight Product from NASA’s Short-term Prediction Research and Transition (SPoRT) Center is so important. Fatal lightning incidents by month according to the National Lightning Safety Council. NASA/National Lightning Safety Council For instance, at last year’s Rock the South concert in Cullman, Alabama, the National Weather Service (NWS) in Huntsville used the Stoplight Product to effectively communicate the lightning threat to concert emergency managers, demonstrating its practical application in safeguarding public events. The popular sayings, “When thunder roars, go indoors” and “See a flash, dash inside,” are common reactive responses to severe weather. According to NOAA’s lightning safety protocols, waiting 30 minutes after the last lightning strike is recommended before resuming outdoor activities. However, tools like the Stoplight Product provide real-time lightning activity data, helping individuals and organizations make informed safety choices before weather conditions worsen. Whether for outdoor events, construction sites, or recreational activities, this product enables people to easily determine when lightning was last detected in their area, ensuring better safety and preparedness. In collaboration with NASA Marshall Space Flight Center’s Emergency Operations Center and the National Weather Service in Huntsville, SPoRT has developed innovative tools like the Stoplight Product to empower communities and organizations to take proactive preventive measures. SPoRT’s tools are part of a broader effort to transition research findings into practical applications that benefit forecasters and communities. Kelley Murphy, a research associate at the University of Alabama in Huntsville, frequently interacts with users to train them on how to use the NASA SPoRT Stoplight Product during convective weather events. She said the tool leverages data from the Geostationary Lightning Mapper (GLM) on NOAA’s GOES-16 satellite, which continuously monitors lightning over the ******* States with high resolution. The Stoplight Product visually represents recent lightning activity to help users make informed decisions about outdoor safety. Murphy said the Stoplight Product uses GLM Flash Extent Density data to determine the age and location of lightning flashes. GLM pixels are ******** based on how recently lightning occurred, creating an easy-to-interpret visual aid of lightning within the last 30 minutes. Red indicates lightning within the last 10 minutes, yellow for 10-20 minutes, and green for 20-30 minutes, with the ****** disappearing after 30 minutes without lightning. There is also an option for ******-****** users embedded in the tool. Kristopher White is the Applications Integration Meteorologist and senior forecaster at the Huntsville NWS office, spending half his time with NASA SPoRT. White plays a key role in transitioning research into operational use, coordinating the use of these tools within the NWS, and ensuring that forecasters are trained and equipped to utilize them effectively. NASA SPoRT Stoplight Product visually represents recent lightning activity to help users make informed decisions about outdoor safety. NASA White said this product has received positive feedback from various NWS offices across the U.S. Forecasters have reported utilizing the tool to monitor storms and make decisions during events, emphasizing its practical value in real-world scenarios. One forecaster from NWS Raleigh noted that they were able to warn about lightning at a 1000+ attendee event; “We were able to alert them that lightning was nearby and then gave the all-clear once it moved out of the critical area.” Another forecaster from NWS Sullivan stated, “There’s a lot of good stuff out there that we’re using to paint the picture for us and the decision-makers, but the GLM Stoplight Product has been one of our ‘go-to’s’ for assessing how long it’s been since the last flash.” This ability to provide real-time lightning information aids forecasters in relaying crucial data to emergency managers, supporting public safety efforts. Looking ahead, the SPoRT team is working on enhancements to the Stoplight Product, incorporating ground-based lightning detection data to improve accuracy. This new version seeks to address issues such as the parallax effect, where the satellite’s perspective can slightly shift the perceived location of lightning strikes. By combining satellite and ground-based data, the improved product will offer more precise information, enhancing its utility for lightning safety. As we move through the peak months of the lightning season – June, July, and August – tools like these become even more helpful. Murphy and White stress the value of using these resources for professional meteorologists and the public. The Stoplight Product is GPS-enabled and available in a custom viewer that can be accessed on both computers and mobile devices, allowing individuals to make safer choices when engaging in outdoor activities, particularly during the summer weather. On their seasonal outlook, NOAA’s Climate Prediction Center suggests above-normal precipitation for much of the Southeast and Eastern Seaboard this year, which could imply increased lightning activity. This emphasizes the need for reliable tools to mitigate lightning-related risks. Lightning Safety Awareness Week, from June 23-29, highlighted the importance of taking safety measures during peak lightning season. SPoRT’s Stoplight Product and other tools represent significant advancements in lightning detection and decision support, helping forecasters and the public stay informed and safe. As we navigate this season, utilizing these resources will be essential in reducing the impact of lightning-related hazards.

July 3, 2024 RELEASE: J24-011 Former Chief Astronaut Patrick Forrester NASA NASA astronaut Patrick G. Forrester retired June 29, after a career spanning 31 years of service and three spaceflights. He went on to become chief of NASA’s Astronaut Office, and most recently served as an advisor to the associate administrator for the Space Operations Mission Directorate at NASA Headquarters in Washington. Forrester joined the agency in 1993 as an aerospace engineer at NASA’s Johnson Space Center in Houston and was selected to become an astronaut in 1996. He dedicated his early career to the assembly of the International Space Station, spending 40 days in space and completing four spacewalks totaling 25 hours and 30 minutes. “Pat’s dedication and commitment to the advancement of human space exploration over the past three decades has been an inspiration, not just to the Johnson workforce, but the Artemis generation as well,” said NASA’s Johnson Space Center Director Vanessa Wyche. “I want to extend my sincere gratitude to Pat for his outstanding contributions. His legacy will continue to impact the agency and the next generation of explorers for many years to come. Many congratulations to Pat; I wish him all the best in his retirement.” Forrester launched to the space station for the first time in August 2001 aboard space shuttle Discovery in support of STS-105. Forrester was the mission’s prime robotics operator, helping to install the Leonardo Multi-Purpose Logistics Module that would help deliver 2.7 metric tons of supplies to the station. He flew again with STS-117 in June 2007 aboard space shuttle Atlantis, delivering the orbiting laboratory’s second starboard truss and its third set of solar arrays. His final spaceflight, STS-128 aboard Discovery, launched in August 2009. As prime robotics officer, Forrester again installed Leonardo and the crew transferred 18,000 pounds of supplies. Forrester continued to support the astronaut corps through numerous leadership positions, serving as technical assistant to the director of Flight Crew Operations. He was a crew representative of robotics development on the space station and shuttle training and onboard crew procedures. Forrester also held the role of spacecraft communicator, or CAPCOM, for both station and shuttle missions. In 2017, Forrester became chief of the Astronaut Office, overseeing the first flights of NASA’s Commercial Crew Program and helping develop the initial architecture for the agency’s Artemis campaign. In 2020, he stepped down from his chief position, handing over to NASA astronaut Reid Wiseman. “Pat’s leadership was instrumental during a time where NASA was just starting to launch our astronauts from ********* soil again,” said Norm Knight, director of flight operations at NASA Johnson. “I admire his courage, his tenacity, and his character during such a dynamic time in our history, and I thank him for laying a strong foundation, not just in his role as chief astronaut, but through his career in human spaceflight. To me, he is a mentor and a friend, and I wish him all the best.” At the time of his retirement, Forrester supported the Space Operations Mission Directorate, serving as the director of the Cross-Directorate Technical Integration Office and an adviser to the directorate’s associate administrator and fellow NASA astronaut Ken Bowersox. “Pat is an incredible leader who has provided invaluable service to NASA’s astronaut corps and human spaceflight during his career,” said Ken Bowersox, associate administrator for space operations at NASA. “In the Space Operations Mission Directorate, his influence will be felt long after his departure as we continue to work every day in low Earth orbit and prepare for the future near Earth, at the Moon, Mars and into the solar system.” An El Paso, Texas, native, Forrester earned a bachelor of science degree in applied sciences and engineering from the U.S. Military Academy, West Point, New York, and a master of science in mechanical and aerospace engineering from the University of Virginia, Charlottesville. A retired colonel in the U.S. Army, Forrester logged more than 5,300 hours of flight time in over 50 different aircraft as an operational aviator and test pilot, retiring in 2005. “It has been an honor to serve our nation as a member of the NASA family. Many of the stories I will tell for the rest of my life will be related to my experiences here,” said Forrester. “I look forward to watching my friends and colleagues circle the Moon and eventually land on its surface – with the help of all those serving faithfully on the ground. I am forever grateful.” Read Forrester’s full biography at: [Hidden Content] -end- Chelsey Ballarte Johnson Space Center, Houston 281-483-5111 *****@*****.tld View the full article

NASA/Radislav Sinyak Technicians lift NASA’s Orion spacecraft out of the Final Assembly and System Testing cell on June 28, 2024. The integrated spacecraft, which will be used for the Artemis II mission to orbit the Moon, has been undergoing final rounds of testing and assembly, including end-to-end performance verification of its subsystems and checking for leaks in its propulsion systems. A 30-ton crane returned Orion into the recently renovated altitude chamber where it underwent electromagnetic testing. The spacecraft now will undergo a series of tests that will subject it to a near-vacuum environment by removing air, thus creating a space where the pressure is extremely low. This results in no atmosphere, similar to the one the spacecraft will experience during future lunar missions. The data recorded during these tests will be used to qualify the spacecraft to safely fly the Artemis II astronauts through the harsh environment of space. Get updates on the Artemis II mission.

NASA astronaut Andre Douglas poses for a portrait at NASA’s Johnson Space Center in Houston.Credits: NASA/Josh Valcarcel NASA has selected astronaut Andre Douglas as its backup crew member for the agency’s Artemis II test flight, the first crewed mission under NASA’s Artemis campaign. Douglas will train alongside NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and ********* Space Agency (CSA) astronaut Jeremy Hansen. In the event a NASA astronaut is unable to take part in the flight, Douglas would join the Artemis II crew. “Andre’s educational background and extensive operational experience in his various jobs prior to joining NASA are clear evidence of his readiness to support this mission,” said Joe Acaba, chief astronaut at NASA’s Johnson Space Center in Houston. “He excelled in his astronaut candidate training and technical assignments, and we are confident he will continue to do so as NASA’s backup crew member for Artemis II.” The CSA announced Jenni Gibbons as its backup crew member in November 2023. Gibbons would step into the mission to represent Canada should Hansen not be available. “Canada’s seat on the historic Artemis II flight is a direct result of our contribution of Canadarm3 to the lunar Gateway. Jenni Gibbons’ assignment as backup is of utmost importance for our country,” said CSA President Lisa Campbell. “Since being recruited, Jenni has distinguished herself repeatedly through her work with NASA and the CSA. She is also a tremendous role model for Canada’s future scientists, engineers, and explorers.” The selection of Douglas and Gibbons as backup crew members for Artemis II is independent of the selection of crew members for Artemis III. NASA has not yet selected crew members for Artemis flights beyond Artemis II. All active NASA astronauts are eligible for assignment to any human spaceflight mission. The approximately 10-day Artemis II test flight will launch on the agency’s powerful SLS (Space Launch System) rocket, prove the Orion spacecraft’s life-support systems, and validate the capabilities and techniques needed for humans to live and work in deep space. More on Artemis II backup crew Douglas graduated from NASA’s astronaut candidate training program in March 2024. He is a Virginia native and earned a bachelor’s degree in Mechanical Engineering from the U.S. Coast Guard Academy in New London, Connecticut, as well as four post-graduate degrees from various institutions, including a doctorate in Systems Engineering from George Washington University in Washington. Douglas served in the U.S. Coast Guard as a naval architect, salvage engineer, damage control assistant, and officer of the deck. He also worked as a staff member at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, working on maritime robotics, planetary defense, and space exploration missions for NASA. Douglas participated in the ****** EVA and Human Surface Mobility Test Team 5, working with a specialized group that develops, integrates, and executes human-in-the-loop tests, analog missions, and Moonwalks. Most recently, Douglas worked with teams on the development of the lunar terrain vehicle, pressurized rover, lunar Gateway and lunar spacesuit. Gibbons was recruited as a CSA astronaut in 2017 and completed her basic training in 2020. Since then, Gibbons has continued to serve Canada’s space program and has worked in different positions, including Mission Control as a capsule communicator (CAPCOM) during spacewalks, and commercial spacecraft and daily International Space Station operations. Gibbons holds an honors bachelor’s degree in Mechanical Engineering from McGill University in Montreal. While at McGill, she conducted research on flame propagation in microgravity in collaboration with CSA and Canada’s National Research Council Flight Research Laboratory in Ontario. She holds a doctorate in engineering from ****** College at the University of Cambridge, England. Under NASA’s Artemis campaign, the agency is establishing the foundation for long-term scientific exploration at the Moon, land the first woman, first person of ******, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

The Goldstone Solar System Radar, part of NASA’s Deep Space Network, made these observations of the recently discovered 500-foot-wide (150-meter-wide) asteroid 2024 MK, which made its closest approach — within about 184,000 miles (295,000 kilometers) of Earth — on June 29.NASA/JPL-Caltech The Deep Space Network’s Goldstone planetary radar had a busy few days observing asteroids 2024 MK and 2011 UL21 as they safely passed Earth. Scientists at NASA’s Jet Propulsion Laboratory in Southern California recently tracked two asteroids as they flew by our planet. One turned out to have a little moon orbiting it, while the other had been discovered only 13 days before its closest approach to Earth. There was no risk of either near-Earth object impacting our planet, but the radar observations taken during these two close approaches will provide valuable practice for planetary defense, as well as information about their sizes, orbits, rotation, surface details, and clues as to their composition and formation. Passing Earth on June 27 at a distance of 4.1 million miles (6.6 million kilometers), or about 17 times the distance between the Moon and Earth, the asteroid 2011 UL21 was discovered in 2011 by the NASA-funded Catalina Sky Survey, in Tucson, Arizona. But this is the first time it has come close enough to Earth to be imaged by radar. While the nearly mile-wide (1.5-kilometer-wide) object is classified as being potentially hazardous, calculations of its future orbits show that it won’t pose a threat to our planet for the foreseeable future. Because close approaches by asteroids the size of 2024 MK are relatively rare, JPL’s planetary radar team gathered as much information about the near-Earth object as possible. This mosaic shows the spinning asteroid in one-minute increments about 16 hours after its closest approach with Earth.NASA/JPL-Caltech Using the Deep Space Network’s 230-foot-wide (70-meter) Goldstone Solar System Radar, called Deep Space Station 14 (DSS-14), near Barstow, California, JPL scientists transmitted radio waves to the asteroid and received the reflected signals by the same antenna. In addition to determining the asteroid is roughly spherical, they discovered that it’s a binary system: A smaller asteroid, or moonlet, orbits it from a distance of about 1.9 miles (3 kilometers). “It is thought that about two-thirds of asteroids of this size are binary systems, and their discovery is particularly important because we can use measurements of their relative positions to estimate their mutual orbits, masses, and densities, which provide key information about how they may have formed,” said Lance Benner, principal scientist at JPL who helped lead the observations. These seven radar observations by the Deep Space Network’s Goldstone Solar System Radar shows the mile-wide asteroid 2011 UL21 during its June 27 close approach with Earth from about 4 million miles away. The asteroid and its small moon (a bright dot at the bottom of the image) are circled in white.NASA/JPL-Caltech Second Close Approach Two days later, on June 29, the same team observed the asteroid 2024 MK pass our planet from a distance of only 184,000 miles (295,000 kilometers), or slightly more than three-quarters of the distance between the Moon and Earth. About 500 feet (150 meters) wide, this asteroid appears to be elongated and angular, with prominent flat and rounded regions. For these observations, the scientists also used DSS-14 to transmit radio waves to the object, but they used Goldstone’s 114-foot (34-meter) DSS-13 antenna to receive the signal that bounced off the asteroid and came back to Earth. The result of this “bistatic” radar observation is a detailed image of the asteroid’s surface, revealing concavities, ridges, and boulders about 30 feet (10 meters) wide. Close approaches of near-Earth objects the size of 2024 MK are relatively rare, occurring about every couple of decades, on average, so the JPL team sought to gather as much data about the object as possible. “This was an extraordinary opportunity to investigate the physical properties and obtain detailed images of a near-Earth asteroid,” said Benner. This sunset photo shows NASA’s Deep Space Station 14 (DSS-14), the 230-foot-wide (70-meter) antenna at the Goldstone Deep Space Communications Complex near Barstow, California.NASA/JPL-Caltech The asteroid 2024 MK was first reported on June 16 by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) at Sutherland Observing Station in South *******. Its orbit was changed by Earth’s gravity as it passed by, reducing its 3.3-year orbital ******* around the Sun by about 24 days. Although it is classified as a potentially hazardous asteroid, calculations of its future motion show that it does not pose a threat to our planet for the foreseeable future. The Goldstone Solar System Radar Group is supported by NASA’s Near-Earth Object Observations Program within the Planetary Defense Coordination Office at the agency’s headquarters in Washington.

It may seem remarkable that no ********* spent the Fourth of July holiday in space for the first 21 years of human spaceflight. Not until 1982 and the 35th U.S. human spaceflight did Americans awaken in space on Independence Day, and then bring their spacecraft back to Earth later in the day to a rousing welcome by the President of the ******* States. Another 10 years elapsed before more Americans found themselves in orbit on July 4. But as flight rates and crew sizes increased, and as Americans began living and working aboard space stations, spending the holiday in orbit turned into an annual event, celebrated with crew members from other nations. Through 2024, 73 Americans have celebrated Independence Day in space, eight of them twice, each in a unique style. July 4, 1982 – A tale of three shuttles. Left: Space shuttle Columbia makes a touchdown at Edwards Air Force Base (AFB) in California to end the STS-4 mission. Middle: With space shuttle Enterprise as a backdrop, President Ronald W. Reagan, First Lady Nancy Reagan, and NASA Administrator James M. Beggs welcome home STS-4 astronauts Thomas K. “TK” Mattingly and Henry W. Hartsfield. Right: Space shuttle Challenger departs Edwards AFB atop its Shuttle Carrier Aircraft on its way to NASA’s Kennedy Space Center in Florida. For the first 21 years of human spaceflight, no ********* astronaut had spent a Fourth of July in space. That all changed with the STS-4 mission. On July 4, 1982, the final day of their flight, astronauts Thomas K. ‘TK’ Mattingly and Henry W. “Hank” Hartsfield guided space shuttle Columbia to its first concrete runway landing at Edwards Air Force Base in California. President Ronald W. Reagan, who two years later instructed NASA to develop a space station, and First Lady Nancy Reagan greeted Mattingly and Hartsfield on the runway as they disembarked from Columbia. Shortly thereafter, the President led a celebration in front of space shuttle Enterprise, saying, “TK and Hank, you’ve just given the ********* people a Fourth of July present to remember.“ To cap off the event attended by 45,000 people and broadcast live on television, President Reagan gave the signal for the Shuttle Carrier Aircraft carrying Challenger, NASA’s newest space shuttle orbiter, to take off to begin its transcontinental ferry flight to NASA’s Kennedy Space Center (KSC) in Florida. Left: The STS-50 crew in July 1992. Right: The international STS-71 crew in July 1995. Ten years passed before ********* astronauts once again celebrated the Fourth of July holiday in space. The seven astronauts of STS-50 had completed about half of their 14-day USML-1 mission on July 4, 1992, but the busy pace of the science flight allowed little time for celebrations. Three years later, 10 people orbited the Earth during the historic STS-71 first shuttle docking mission to the Mir space station. In fact, on July 4, 1995, space shuttle Atlantis undocked from Mir, returning NASA astronaut Norman E. Thagard and his two cosmonaut colleagues from a four-month mission aboard Mir. By coincidence, for NASA astronauts Bonnie J. Dunbar and Ellen S. Baker, this marked their second Fourth of July in space as they both served on the STS-50 crew three years earlier. The day’s undocking activities left little time for celebrating, although Mission Control played “America the Beautiful” as the wake-up song that morning. To satisfy Thagard’s request, following their landing at KSC, ground teams treated him and his colleagues to some belated Fourth of July fare of hot dogs, hamburgers, and hot fudge sundaes. July 4, 1996. Left: Shannon W. Lucid aboard the space station Mir. Right: Susan J. Helms in the Spacelab module during the STS-78 mission. Following Thagard, six other NASA astronauts completed long-duration missions aboard Mir. From March to September 1996, Shannon W. Lucid spent six months aboard the Russian station and as the lone ********* on the Mir 21 crew, she celebrated the Fourth of July by wearing distinctive Stars-and-Stripes socks. Elsewhere in low Earth orbit, with much of their 17-day Life and Microgravity Sciences mission behind them, the international crew of STS-78 celebrated the Fourth of July holiday aboard space shuttle Columbia. By sheer coincidence, astronaut Susan J. Helms wore Stars-and-Stripes socks identical to Lucid’s. July 4, 1997. Left: C. Michael Foale aboard the space station Mir. Right: The STS-94 crew aboard space shuttle Columbia. In 1997, C. Michael Foale took his turn as the resident NASA astronaut aboard Mir. On June 25, a Progress cargo vehicle collided with the station, depressurizing its Spektr module, the one Foale used as sleeping quarters and as a laboratory. On July 4, Foale and his two cosmonaut colleagues, still dealing with the accident’s aftermath and preparing to receive a new cargo craft with critical supplies, did not have time for celebrations. Foale spoke with NASA Administrator Daniel S. Goldin, who called to check on his status and wish him a happy holiday. Concurrently, the seven-member all-NASA STS-94 crew also spent July 4, 1997, in space during the Microgravity Science Laboratory mission aboard space shuttle Columbia. With eight NASA astronauts in orbit, although aboard two spacecraft, this still holds the record as the largest number of Americans off-planet on a Fourth of July. Left: July 4, 2001. Expedition 2 crew members NASA astronauts Susan J. Helms, left, and James S. Voss. Middle: July 4, 2006. The crew of STS-121 wave ********* (and one *******) flags as they depart crew quarters for their Fourth of July launch. Right: July 4, 2010. NASA astronauts Douglas H. Wheelock, Tracy Caldwell Dyson, and Shannon Walker of Expedition 24. The start of continuous human habitation aboard the International Space Station in November 2000 has meant that every year since, at least one ********* astronaut has spent the Independence Day holiday in space. James S. Voss and Susan J. Helms of Expedition 2, the first NASA astronauts to spend the Fourth of July aboard the space station in July 2001, sent an “out of this world” birthday message to America, played during “A Capitol Fourth” celebration in Washington, D.C. For Helms, this marked her second July 4 spent in space in five years. For each of the next eight years, crew rotations and other factors resulted in only one NASA astronaut residing aboard the space station during the Fourth of July holiday. Celebrations tended to be low key, but the entire crew regardless of nationality had the day off from their regular duties. July 4, 2006, marked the first and so far only time that an ********* crewed spacecraft launched on Independence Day, the liftoff like a giant birthday candle. As they left crew quarters for the ride to the launch pad, the seven-member crew of STS-121 waved flags, six ********* and one *******, for the ********* Space Agency astronaut. With Jeffery N. Williams working aboard the space station, once the STS-121 crew reached orbit, the seven NASA astronauts comprised the largest number of Americans in space on Independence Day since 1997. In 2010, Expedition 24 marked the first time that three NASA astronauts, Douglas H. Wheelock, Tracy Caldwell Dyson, and Shannon Walker, celebrated the Fourth of July aboard the space station. Wheelock marked the holiday by posting a message on social media about a Congressional Medal of Honor belonging to a soldier ******* in action in Vietnam that he took to space. July 4, 2013. Left: Expedition 36 astronaut Christopher J. Cassidy wears a T-shirt from the Four on the Fourth race in York, Maine. Right: Fellow Expedition 36 astronaut Karen L. Nyberg displays her Fourth of July creation of a cookie she iced in the colors of the ********* flag. For Independence Day 2013, Expedition 36 astronaut Christopher J. Cassidy chose to run in the Four on the 4th road race in his hometown of York, Maine. The fact that he lived and worked aboard the space station did not stop him from participating. Wearing the race’s T-shirt, he videotaped a message for the runners in York, and ran on the station’s treadmill, watching a video of the previous year’s race. At the end of the video message, Cassidy encouraged everyone to “celebrate our nation’s birthday with family and friends.” Cassidy and fellow Expedition 36 astronaut Karen L. Nyberg celebrated Independence Day by icing cookies in the colors of the ********* flag. Left: July 4, 2015. NASA astronaut Scott J. Kelly records a Fourth of July message during Expedition 44. Right: July 4, 2017. During Expedition 52, NASA astronauts Jack D. Fischer and Peggy A. Whitson show off their patriotic outfits. On July 4, 2015, NASA astronaut Scott J. Kelly, in the fourth month of his nearly one-year mission aboard the space station, recorded a Fourth of July message for Earthbound viewers. He wished everyone a Happy Independence Day and hoped that he would be able to see some of the fireworks around the country from his lofty perch, orbital mechanics permitting. As crew size aboard the space station increased and crew rotations changed, NASA astronaut Jeffrey N. Williams, celebrating his second Fourth of July in orbit during Expedition 48, holds the distinction as the last ********* to spend Independence Day alone in space on July 4, 2016. The following year, Expedition 52 astronauts Jack D. Fischer and Peggy A. Whitson recorded a whimsical video, posting it on social media, showing their patriotic attire in various poses. Left: July 4, 2018. The Expedition 56 crew found the ********* flag originally flown aboard STS-1 and brought to the space station by STS-135. Right: July 4, 2019. Expedition 60 astronauts Christina H. Koch and Tyler N. “Nick” Hague in their finest patriotic outfits. For Independence Day 2018, Expedition 56 astronauts Andrew J. “Drew” Feustel, Richard R. “Ricky” Arnold, and Serena M. Auñón-Chancellor retrieved a very special flag from stowage. The 8-by-12-inch ********* flag first flew into space aboard STS-1, the space shuttle’s inaugural flight, in April 1981. One of a thousand flags flown, it ended up in storage for 20 years until retrieved and flown to the space station on the space shuttle’s final mission, STS-135, in July 2011. The label on the Legacy Flag, “Only to be removed by crew launching from KSC,” referred to the next launch of ********* astronauts from ********* soil aboard an ********* spacecraft, anticipated sometime after the shuttle’s retirement aboard a commercial provider. More on this flag’s incredible journey below. For Independence Day 2019, Expedition 60 astronauts Tyler N. “Nick” Hague and Christina H. Koch, in the fourth month of her record-breaking 11-month mission, to date the longest single flight by a woman, recorded a video message for Earthbound viewers. In particular, they thanked servicemen deployed around the world and reflected on the bright future for America’s human spaceflight program. Left: July 4, 2020. Expedition 63 astronauts Christopher J. Cassidy, left, Douglas G. Hurley, and Robert L. Behnken, hold the Legacy Flag flown on STS-1 and STS-135. Right: July 4, 2021. The Expedition 65 crew, K. Megan McArthur, left, Mark T. Vande Hei, and R. Shane Kimbrough, tapes a Fourth of July message. During their Independence Day video message on July 4, 2020, Expedition 63 astronauts Christopher J. Cassidy, Douglas G. Hurley, and Robert L. Behnken wished Americans a happy Fourth of July, and looked ahead to future missions to the Moon and beyond. Behnken, holding the Legacy Flag that had waited for them aboard the station for nine years, added that he and Hurley would return it to the ground since they had arrived aboard the first ********* crewed vehicle to launch from ********* soil following the retirement of the space shuttle. He indicated that the flag would later return to space aboard the first ********* crewed flight to the Moon as part of the Artemis program. In their video message on July 4, 2021, Expedition 65 astronauts K. Megan McArthur, R. Shane Kimbrough, and Mark T. Vande Hei wished everyone a Happy Fourth of July and looked forward to future exploration missions to the Moon. July 4, 2022. Left: Expedition 67 NASA astronauts Robert T. Hines, left, and Kjell N.

July 4, 2024, finds six NASA astronauts, the largest number of Americans in space on the Fourth of July since 2006, aboard the space station, having arrived by three different vehicles – Matthew S. Dominick, Michael R. Barratt, and Jeanette J. Epps by Crew Dragon, Tracy Caldwell Dyson by Soyuz, and Barry E. “Butch” Wilmore and Sunita L. Williams by Starliner. For Barratt and Dyson, this marked their second July 4 holiday in space. In the coming years, more ********* astronauts will celebrate Independence Day aboard the space station, and one day we can look forward to some of them celebrating the holiday on or near the Moon.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s ECOSTRESS instrument on June 19 recorded scorching roads and sidewalks across Phoenix where contact with skin could cause serious burns in minutes to seconds, as indicated in the legend above. NASA/JPL-Caltech Roads and sidewalks in some areas get so hot that skin contact could result in second-degree burns. Researchers at NASA’s Jet Propulsion Laboratory in Southern California have mapped scorching pavement in Phoenix where contact with skin — from a fall, for example — can cause serious burns. The image shows land surface temperatures across a grid of roads and adjacent sidewalks, revealing how urban spaces can turn hazardous during hot weather. Data for this visualization of the Phoenix area — the fifth most populous city in the ******* States — was collected at 1:02 p.m. local time on June 19, 2024, by a NASA instrument aboard the International Space Station. Called ECOSTRESS (short for the Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station), the instrument measures thermal infrared emissions from Earth’s surface. The image shows how miles of asphalt and concrete surfaces (******** here in yellow, red, and purple, based on temperature) trap heat. The surfaces registered at least 120 degrees Fahrenheit (49 degrees Celsius) to the touch — hot enough to cause contact burns in minutes to seconds. The image also shows cooling effects of green spaces in communities like Encanto and Camelback East, in contrast to the hotter surface temperatures seen in Maryvale and Central City, where there are fewer parks and trees. “We create these maps to be intuitive to users and help make data more accessible to the public and citizens scientists,” said Glynn Hulley, a JPL climate researcher. “We see them as a vital tool for planning effective heat interventions, such as tree planting, that can cool down the hottest roads and sidewalks.” Homing in on Heat At the lower right of the image is Phoenix’s Sky Harbor International Airport, where ECOSTRESS recorded some of the hottest land surface temperatures within the city —around 140 F (60 C). The air temperature on June 19 at the airport reached 106 F (43 C). Air temperature, which is measured out of direct sunlight, can differ significantly from the temperature at the land surface. Streets are often the hottest surfaces of the built environment due to dark asphalt paving that absorbs more sunlight than lighter-******** surfaces; asphalt absorbs up to 95% of solar radiation. These types of surfaces can easily be 40 to 60 degrees F (22 to 33 degrees C) hotter than the air temperature on a very hot day. Launched to the International Space Station in 2018, ECOSTRESS has as its primary mission the identification of plants’ thresholds for water use and water stress, giving insight into their ability to adapt to a warming climate. But the instrument is also useful for documenting other heat-related phenomena, like patterns of heat absorption and retention. To produce the image of Phoenix, scientists used a machine learning algorithm that incorporates data from additional satellites: NASA/USGS Landsat and Sentinel-2. The combined measurements were used to “sharpen” the surface temperatures to a resolution of 100 feet (30 meters) by 100 feet (30 meters). More About the Mission JPL built and manages the ECOSTRESS mission for the Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington.

NASA/Matthew Dominick NASA astronaut Matthew Dominick captured this image of Hurricane Beryl in the Caribbean on July 1, 2024, while aboard the International Space Station, and posted it to X. The Category 4 hurricane had winds of about 130 mph (215 kph). Hurricanes – tropical cyclones that form over the Atlantic Ocean or the eastern Pacific Ocean – use warm, moist air as fuel. The warm, moist air over the ocean rises upward from near the surface, causing an area of lower air pressure below. Air from surrounding areas with higher air pressure pushes into the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface. NASA studies hurricanes from space through photos like this one, as well as observations from satellites. This vantage point helps scientists understand how climate change impacts hurricanes and learn how communities can better prepare for tropical cyclones in a warmer world.

Explore Lagniappe for July 2024 featuring: NASA Stennis Achieves Primary Success for Historic In-Space Mission Mississippi Comic Convention Experiences NASA NASA Stennis Hosts Take Our Children to Work Day Gator Speaks Conversations filled the room with anticipation for the day ahead. NASA’s Stennis Space Center hosted Take Our Children to Work Day on June 27 with a day set aside for children of employees to see up close the work carried out at NASA Stennis by its diverse workforce. A video featuring NASA Stennis Associate Director Rodney McKellip welcomed the enthusiastic crowd. He shared about the different hats worn by the more than 5,000 employees throughout the NASA Stennis federal city. There are engineers who help make the south Mississippi NASA center the premier rocket engine test facility in the country. NASA Stennis, the place that tested rocket stages to put the first humans on the Moon, ******** on the frontlines of preparing NASA and the ******* States for its return to the Moon through the Artemis campaign to explore more of the lunar surface than ever before. Those attending Take Our Children to Work Day learned how NASA Stennis has many rocket scientists and test engineers carrying out this work, but that is not all. Gator SpeaksNASA/Stennis A team of folks, including accountants, lawyers, environmental specialists, educators, and public affairs specialists, wear the NASA hat to ensure mission success too. There also are teams climbing on test stands, installing rocket engines into the stands, working with piping, electrical, welding, construction projects, safety inspections, and more. In addition to being the premier propulsion test site supporting NASA’s mission, NASA Stennis is where commercial companies experience success and benefit from the expertise of NASA personnel. Companies like Relativity Space, Rocket Lab, and Evolution Space have established ongoing operations at NASA Stennis as the commercialization of space continues. The NASA Stennis federal city also includes a range agencies, universities, and companies sharing costs and carrying out individual missions. It is the command site for the largest collection of oceanographers in the world and where Navy Seals train. Participants learned about such operations from a panel of employees from NASA, Aerojet Rocketdyne, an L3 Harris Technologies company, Lockheed Martin, and Relativity Space. They toured NASA Stennis and participated in activities facilitated by NASA, Aerojet Rocketdyne, and the National Data Buoy Center. The NASA Stennis associate director left them with a final thought before their day started: If you hear something loud during the day, just know that is the sound of progress at the nation’s premier rocket propulsion test facility and federal city known as NASA Stennis. Sure enough, that afternoon, the unmistakable sound of engine testing could be heard across the site. For this ol‘ Gator, it sounds like music to the ears.

Read More About Mission Success Mississippi Comic Convention Experiences NASA Science fiction fans at the Mississippi Comic Convention were provided an out-of-this world experience, while learning about NASA, during the two-day event in Jackson, Mississippi, thanks to employees from NASA’s Stennis Space Center. “I’ve never been to an outreach activity that you reached so many people and from such a wide spectrum of people, from grade schoolers to retired grandparents,” said Troy Frisbie, NASA Stennis legislative affairs officer and chief of staff. “We interacted with a wide audience and really shared how NASA and NASA Stennis benefit all. It was a really, really good experience.” The NASA booth, at an event that attracted 18,000 people to the Mississippi Trade Mart and Coliseum on June 22-23, featured an immersive experience with virtual reality goggles. Participants were able to view an engine test conducted at NASA Stennis, take a virtual spacewalk while visiting the International Space Station, and experience a simulated rocket launch to Mars. One group enjoying the interaction with NASA was the Star Trek fan club from Jackson, Mississippi. “They were real big supporters of NASA,” Frisbie said. “They loved the virtual reality experience and encouraged others at the convention to come by and visit with us.” NASA Stennis budget analyst Rebecca Mataya and engineers Paul Fuller, Steven Helmstetter, and Chris Barnett-Woods volunteered with Frisbie. The center employees talked to college students majoring in engineering, graphic design, architecture, education, and healthcare. “The assumption is everybody has to be an engineer to work at NASA, and that is not the case,” Frisbie said. “There are all kinds of opportunities, and that was an eye opener for many.” Conversations centered on job opportunities and careers with NASA, as well as work conducted at NASA Stennis. The volunteers also fielded general questions about NASA’s powerful SLS (Space Launch System) rocket and the agency’s Artemis campaign of returning astronauts to the Moon for scientific discovery, economic benefits, and inspiration for a new generation of explorers: the Artemis Generation. “We enjoyed telling the NASA story and how NASA Stennis on the Gulf Coast of Mississippi serves as an economic engine that contributes to this nation’s space dreams,” Frisbie added.

Chris Barnett-Woods is shown at the E-1 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, where NASA Stennis accelerates the exploration and commercialization of space and innovates to benefit NASA and industry.NASA/Danny Nowlin Chris Barnett-Woods’ favorite movie growing up – Back to the Future – led him to dream of one day building a DeLorean automobile. Instead, the electrical engineer is doing something never imagined as he helps NASA support the commercialization of space for the benefit of all. “If there is any interest, always apply to work at a place like NASA because you never know where it will take you,” said Barnett-Woods, who is approaching two decades of work at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. “In college, I never thought I would work for NASA. I thought it was a far-off fantasy and could not be a reality. Turns out, it was closer than I thought.” The Diamondhead, Mississippi, resident is in his 10th year as a NASA engineer and 17th overall at NASA Stennis, following seven years as a contractor before joining NASA. Barnett-Woods is the electrical lead and instrumentation engineer at the E-1 Test Stand. It has four test cell positions and is a part of the versatile four-stand E Test Complex at NASA Stennis. Overall, the complex includes 12 active test cell positions capable of various component, engine, and stage test activities. He describes the customer-focused approach at E-1 as a fast-paced workflow in a constant phase of testing while always keeping safety at the forefront. “Safety is priority number one, followed by collecting data to help our customers,” said Barnett-Woods. “We ensure everyone goes home in the condition they entered. There is no hesitation that if we are entering an unsafe process or configuration, we will stop right there and make sure we are doing it the right way.” A typical day for the engineer includes running a system calibration, which ensures all sensors on the facility and test article are reading accurately, followed by red line checks. The red line checks help maintain a safe work environment in the event a pressure or temperature goes too high. If that were to happen, this process will safely shut down the engine. Once checks are complete, the hot ***** test begins with flowing fuel and oxidizer through the test article to facilitate ******* and record data. The data tells the story of performance and allows for design analysis as engineers determine the most optimal way to run the test article. “It is a fun environment,” the NASA engineer said. “We have a lot of very dedicated people that know the job, love the job, and would do nearly anything for it. We are one big, happy team, like family.” A hot ***** can range between one second to 200 seconds, depending on what is tested. The 2023 NASA Silver Achievement Medal recipient has supported hundreds of hot fires for commercial customers, including companies brand new to the aerospace industry and those more experienced that are looking for specific parameters. “NASA Stennis is a one-of-a-kind facility in the world,” Barnett-Woods said. “This is the only place where we can do a ground level test of an actual engine hot ***** and if you like rockets, this is the place to be.” For information about NASA’s Stennis Space Center, visit: Stennis Space Center – NASA Learn more about the people who work at NASA Stennis View the full article

Xinchuan Huang Let’s start with your childhood, where you were born, where you’re from, your young years, your family at the time, what your parents did, and how early it was in your life that you decided you’d like to pursue a career like the one you’re pursuing now? I was born in a small town in Sichuan, China. It is not far from the famous Emei Mountain, and the beautiful Qingyi river runs through it. At the beginning, I lived with my grandmother’s family in a small village on the riverbank, called “Pond in heaven”. After I left there at four years old, I lived with my parents in Sichuan and Xinjiang provinces, alternatively, as my parents had been working apart. Luckily their reunion came after three years, and finally there was a real “home” for us. My parents were both high school teachers, they worked in the school system opened by a research institute for the children of their employees. It has elementary schools, middle schools, and high schools. That’s where I grew up and received my pre-college education. The Emei Mountain lookout. In China, it is the holy site of Samantabhadra Bodhisattva in Buddhism. Many monkeys live there. Family photo when Xinchuan was 2 yrs. old The Qingyi river runs through Xinchuan’s home village. Since I was young, my mother has taught me enlightenment and urged my study. While my father was not quite involved in my academics, he valued the importance of reading and cultivated my interest in books. Every time we walked into a bookstore together, I was just purely happy because it simply meant one or two new books were coming home with me. He encouraged me to keep expanding my knowledge and horizons by also subscribing to many educational magazines and newspapers for kids, among which I remember two of my most favorite magazines. Before elementary school it was the “Children’s Science Pictorial”, and in elementary school it was the “Youth Science”. Those magazines started and nurtured my interest in science and the universe. In middle school, there was an advertisement for a simple and cheap monocular telescope. I told my dad about it and he helped me order one, even though all it could show was the craters on the moon. But I was so excited, I could lay on the cold ground, watching the moon for hours, as if a new world was unfolding in front of me. Seeing how much I enjoyed it, my father later ordered for me the astronomy volume of the ******** Encyclopedia. It cost 20 Yuan, which was not a small amount at that time. I was so thrilled to have the book. Holding that hardcover book, I felt that I was holding the universe in my arms. I can imagine! But most contents in that encyclopedia were still too advanced for me at the time, so I was more obsessed with the colorful photos in the book. Along with my interest in space and the universe, I was also interested in the topics of UFOs and extraterrestrial civilizations. For example, I read a book called “The Mystery of Flying Saucers”, which was a collection of reports and discussions translated from French. In that book, it mentioned the Drake equation for estimating the likelihood of civilizations in the universe. It deeply impressed me. In 2009, after my postdoc at Ames, I had an opportunity to meet with Dr. Drake. He’s the author of the equation and the founder of the SETI Institute. I must say that not everyone has the opportunity or the luck to meet an idol from their childhood and truly chat with him. Good luck indeed! However, when I told Dr. Drake that my first time reading about his equation was in a book of UFOs, he laughed and said “(it) was in a wrong story!” (laughs) Dr. Drake (left) and Xinchuan at SETI Institute (2010) When I graduated from high school, I did consider a major in astronomy, but there were very few undergraduate astronomy majors in China universities. The only few available that year were either not recruiting in Sichuan or in a city I didn’t like. The famous Peking University did have astrophysics major, but each year they only recruited about 10 undergraduate students from the whole country, and few from Sichuan. Otherwise, I could have enrolled there thirty years ago. Any idea why they didn’t place more emphasis on astronomy? China, as you know, has a strong reputation in space exploration. There is tradition for astronomy in China, and people know of ancient records and scientists, but it likely wasn’t the focus at that time. The astronomy and astrophysics research of Peking university and other China institutions have expanded significantly in last 30 years. That’s for sure. Anyway, I was admitted to the Fudan University in Shanghai, to major in Applied Chemistry II. That’s an interesting name. Usually you see chemistry, applied chemistry, materials chemistry, etc. What does the “II” mean? Previously, it was the Radiochemistry major, but people adjusted its content to keep up with the growth of economy, and to make it easier for their students to find jobs. There was already a major of “Applied Chemistry” in the Chemistry department, so it became “Applied Chemistry II”. My undergraduate thesis was done in the Institute of Laser Chemistry at Fudan, on the UV dissociation of a small organic molecule under cryogenic matrix isolation conditions. Well, you certainly were well served by both your parents, as they helped direct your focus and your education. I also looked it up because I had not remembered that you came to Ames as a postdoc when I was associated with the NPP program as the Ames representative. Yes. In Tim’s Office. From Left to Right: Ryan Fortenberry, Timothy Lee, Xinchuan Huang, and Partha Bera (03/2011) I don’t remember all of them of course as there were quite a few over that ******* of time, but I hope that was a good experience for you. You were working with Tim Lee as your advisor and I’d known him for a very long time. I appreciated and enjoyed the opportunity of doing my postdoc at Ames. I had been thinking of other career choices right before Tim sent an email to Joel (my PhD advisor) asking if there was any student suited for a research project at Ames, about ammonia’s Infrared spectrum calculations. The target was to generate a complete IR line list which people can utilize to characterize the NH3 related celestial environments and eliminate all the NH3 features from the astronomical observations, such as those in Titan’s atmosphere. It was a very good match to my Ph.D. background on the potential energy surface and vibrational dynamics of water cluster ions. You had another postdoc before you came to Ames? At Emory University? Yes, that was more like a one-year extension after the thesis defense, to finish up my Ph.D. projects. How did you get from China to the ******* States? Was it because of your educational pursuits? During my undergraduate study, I had some interest in laser chemistry and spectroscopy. For example, photodissociation products were detected and characterized by their infrared spectrum, and we know the spectroscopic fingerprints of molecules are determined by their nature, or internal properties. After college, I became a graduate student at the Institute of Chemistry, ******** Academy of Science, in Beijing. Supposedly I should learn how to use a femtosecond laser system to investigate some ultra-fast processes in chemical reactions, but my supervisor left the institute unexpectedly. So, I applied to some graduate programs in ******* States, and later enrolled in the chemistry department of Emory University in Atlanta. The admission could be related to my background in laser chemistry labs, but I didn’t continue that path. Instead, I changed to theoretical chemistry and vibrational dynamics studies. But I always admired our colleague experimental spectroscopists working in the laboratories, perhaps because I have myself witnessed how difficult an experimental study could become. It may include sample preparation, optical path platform construction, vacuum pumps, laser tuning, circuit of detectors, hardware interface and software development, etc., so requiring a variety of knowledge and skills from chemistry, physics, to mechanics, electronics, and even materials and computer science. Compared to that, it is relatively simpler to do theoretical spectroscopic studies. But from our perspective, our work still belongs to the laboratory astrophysics. Our lab is set up inside computers, and our equipment and devices are computing programs and algorithms. Did you come to Emory because of a connection or a contact with them? Or did they just have a good program in what you were studying? I applied to several graduate programs in the US, and received admissions including Emory, but I had no connections with them before. I chose the physical chemistry graduate program at Emory, for their reputation in both experimental and theoretical research. So, you applied to several programs and you chose and got admitted to Emory. And then what was your route to Ames? Was it your postdoc? You got a postdoc here and then you stayed? Yes. That’s very straightforward. Straight and simple. Did you know Tim at all beforehand? From a conference or something like that? Not personally, except that he was an expert in Coupled Cluster theory. After Tim contacted my advisor in the summer of 2005, I met him later that year in the ACS meeting at D.C. You were going to tell us something about the work that you are doing, which I found very complicated. It had to do with something called a “potential energy surface” and some other things which I don’t even know what they are, but let’s go ahead because one of the reasons we asked this question is because we want to know why it is important enough that taxpayers should fund research into it. Our research focuses on the Infrared and microwave spectrum ranges, provides high quality spectroscopic constants, or highly accurate Infrared line list predictions for small molecules in outer space. Those molecules play important roles in the interstellar medium, atmospheres of solar system objects, like Venus and Titan, and atmospheres of brown dwarfs and exoplanets. The IR spectroscopic constants and line lists will facilitate the detection of those molecules, help characterize the physical conditions of related environments, determine column densities or atmospheric concentrations, and improve the chemistry evolution models. Since a large part of the astronomical research involves spectrum data analysis and modeling, naturally more reliable and more accurate reference data will be needed to better support NASA strategic goals, help maximize the scientific output of various NASA missions, and eventually help us better understand what’s going on in the universe. Inside SOFIA flight as a Guest Investigator (09/2015) EXES observation towards Orion KL/IRc2 (09/2015) Sgr B2, looking for c-C3H3+ IR features (09/2015) In the last two decades, the generation of more accurate reference data and predictions has required us to combine the advantages of experiments and theories. Our colleagues in Europe adopted similar strategies. For example, the latest Infrared line list we computed for hot carbon dioxide up to 3000 K has several components: high quality ab initio potential energy surface refined using reliable, high resolution experimental data or models, and the best dipole moment surfaces with accuracy already verified by recent highly accurate experiment IR intensities, and the most accurate line positions from the experiment based effective Hamiltonian models. In this way, the spectral line position and intensity accuracy from existing experiment data are integrated with the completeness, reliability and consistency from theoretical predictions. We hope the line list can improve the accuracy of CO2 analysis and modeling for brown dwarf and hot exoplanet atmospheres, which include, but not limited to the recent CO2 discoveries that JWST made on exoplanets. Hot CO2 IR Simulation at 1980 K using our AI-3000K line list, compared to experiment, UCL-4000, and HITEMP2010. See details in “AI-3000K Infrared line list for hot CO2” (Huang et al, 2023, JMSpec) open access. On the other hand, like I mentioned earlier, some molecules, like methyl cyanide, SO2, and ammonia, generate a plethora of spectral lines, appearing like wild grasses. That’s why some molecules were called “weeds”. They’re the “weeds” in the field of spectrum and may overshadow other important signals. Once I looked at a small segment of SOFIA EXES spectrum at 20 mm. Although I already knew it contained hundreds of sulfur dioxide bending mode transitions, I did not expect that so many very weak oscillations and tiny bumps in the observed spectrum could be excellently explained and reproduced until I ran the simulations by myself using SO2 line lists. Without a reliable and complete line list, many weak features may go unnoticed and treated as noises. But when you have a good line list, you can identify all the features of a specific molecule, then try to remove them, like removing weeds, so more interesting features or molecules can be found. We may call them the “flowers”. From this angle, we are like farmers in the spectroscopy field, or treasure hunters in the jungle of spectrum. That’s a good way of putting it. And this leads to a greater understanding of what elements of the NASA mission? How does this fit in with what NASA is trying to accomplish, which could be just exploration, or the search for life, or some of the other great questions that NASA is trying to help answer? There are several potential impacts from the basic scientific research we have been doing. One is to identify those molecules for their existence in the universe, where they are, and how many they are. Second is to figure out what their environment looks like, e.g., the pressure and temperature. An accurate reference line list can help to extract that information from observed spectrum data. The third impact is about some potential biosignature molecules for habitable exoplanets. Like the one we worked on recently, the nitrous oxide or laughing gas, N2O, it is one of those molecules contributing to the transit spectrum of Earth. Another impact is on chemical evolution models. Because our reliable predictions have very high consistency across isotopologues, higher than experiments, we can help to determine more accurate isotopic ratios and evolution history in outer space. In summary, and in the larger picture, we are contributing to the exploration of the universe and the search for habitable planets by providing basic reference data and tools for all NASA missions related to Infrared astronomy, from past Herschel, SOFIA, to JWST, and future ARIEL and other missions. You mentioned biosignatures, which caught my attention because we’re hoping to find some evidence that we’re not alone in the universe, that there is other biology going on somewhere out there. Almost all of our research focuses on trying to address that, at some level. And it has a lot of popular support, taxpayer support, because they want the answer to that question perhaps most of all. The IR spectra based astronomical research involves many models and datasets from different sources, like the spectra modeling on the JWST observations of exoplanet atmospheres. Every piece of work has its own uncertainties, which will add up model by model, database by database. A recent study published in Nature Astronomy revealed that the abundance errors resulting from the opacity inaccuracies can be about one order of magnitude larger than those brought on from JWST-quality observations. This is a bottleneck. From this perspective, our study can help to reduce, or to minimize those uncertainties and errors associated with the opacity data. Compared to experimental measurements under certain conditions, we are trying to provide a complete picture for molecules in the full range of IR and MW spectra. The computed line lists can be used to generate more reliable opacity data at different target temperatures. Having more accurate opacity data with uncertainty reduced or minimized, scientists can determine more accurate properties for exoplanets and other objects in the universe. Have there been any surprising or breakthrough findings or discoveries or something not expected that has come from your work? Not expected? Let me think. We should be careful about the claims on the strengths and limitations of our work. On one side we should have enough confidence, but every molecule is unique, we also need to properly estimate the limitation of our line list predictions. With the synergy between experimental data and high-quality theoretical calculations, many improvements actually can be expected. If we know clearly what we can do and what our limits are, they are not real surprises. Some predictions may look surprising, but they need verifications from future experiments. If verified, the agreement is still expected. If rejected, it means something we need to explain or fix, not real breakthrough or findings. If we really want to talk about “surprises”, I can name two kinds of them. One is that we find surprisingly good agreement or high accuracy verification between predictions and experiments. For example, our room temperature CO2 line list. The IR intensity agreement with the best experiment measurement has reached the level of sub-half percent, for both accuracy and uncertainty, and towards 0.1 %, or permille level, 1‰. It was the best level ever achieved for CO2. That’s kind of a surprise because we were targeting a major upgrade, we knew we were doing better, but we didn’t know the improvements would be so good. That is a good surprise, but there could also be an opposite kind of surprise: a similar molecule or band, similar studies following the same track, so we had assumed it should come out as satisfactory as other molecules or bands, but it did not work out. Then we must figure out what’s going on, what we forgot or missed, or what’s the difference. For example, is that due to some unknown electronic state interference, sensitive resonances, potential defects in potential energy surface, or program bugs, etc.? That is the science part of it. Those are really the surprises. You’re a very impressive and accomplished NASA research scientist, that’s obvious. And you’ve pursued that from youth, really, that line of work. Have you ever given any thought to, if you weren’t doing what you’re doing now, is there another dream job that you might like to have pursued if you had gone another way? When people talk about a dream job, it usually means something that cannot be realized, except in our dreams. Maybe a contractor scientist without the need to worry about funding? But still a scientist? OK, that’s good too. But what things would interest you if you couldn’t be a research scientist anymore? This is just to get into your personality and find out more about you. Oh, if I forget the astronomer or scientist dream from childhood? My dream job has changed several times. Right now, I think it would be interesting to be a local tourist guide. It would indeed. I like that. It is also good for me, not only helps to get familiar with my neighborhood, community, the natural environment, but also gives me some good exercise! (laughs) Right! What advice might you give to a young aspiring student who would like to have a career like yours? When I graduated from high school and went to Fudan University to study chemistry, I had never thought that one day I could still have the opportunity to work for NASA and become a scientist at SETI, Search for Extraterrestrial Intelligence Institute. I also met Dr. Drake and talked to him. In a way this was already infinitely close to my childhood dreams. In this life, I could not become a real astronomer, the most I can do is some basic and auxiliary research work in the field of astrochemistry and theoretical spectroscopy. But looking back from my childhood and my college, I can’t help thinking of a phrase that I read from Steve Jobs, the Apple founder. What he said was something like: “many seemingly unrelated and even useless points in your life may someday eventually connect together to form a path to your dreams. Every piece of past experience will have its meaning and function and role in your career. It Is only then that we can realize their meaning and their role”. This statement roughly applies to me, though of course my experience has been much simpler. I like that quote because we don’t always realize as we’re living and moving forward, the significance of various things that happen. Something that’s just a coincidence can have quite an impact on one’s life or direction. Yes. The universe is infinite, and all the Earth’s science and technology can be found useful in space explorations, sooner or later. If you are interested in the universe, in space sciences, but at the moment you cannot see how your specialty skills or major can be connected to space, don’t worry and don’t give up. Work hard on what you are doing now, whether it’s learning, research, or work, so that when the opportunity comes, you will be ready. My second piece of advice was borrowed from Professor Yuan-Tseh Lee, a Nobel Prize winner in Chemistry. About 20 years ago I met him at a conference. At that time, people were talking about innovations everywhere, but I could not find out how to innovate at all, no matter where I looked, so I asked him for advice. Professor Lee said innovation is not like that; innovation comes from years of continuous accumulation and improvements. He said first you need to get very familiar with what you have at hand, get to the bottom, fully understand principles and techniques of what you are doing, and then try to make improvements. There is always room for improvements, and even a tiny improvement will count and will help. Keep improving, a little bit here, a little bit there. Over time, this will eventually lead to real innovation and breakthroughs. My understanding or take away from his replies, is just like the ancient ******** saying: “No accumulation of steps, no distance to thousands of miles; no accumulation of small streams, there will be no rivers and seas.” That’s it. Very good answer, thought provoking and true. Thank you for sharing that. Would you like to tell us anything about your family? Are you married? Do you have children? Yeah, I’m married, and my wife was also from the Chemistry Department of Emory. But she works in the field of organic chemistry, which I could never figure out since my college years. (laughs) And we have two daughters, one in elementary school and the older one in high school. Our daily lives are kind of routine. Like driving the kids to school, back home doing my work, sometimes accompanying kids doing their homework, taking them to extra-curricular activities, cooking, etc. Rainbow at Ke’e beach (2007) Moreton Bay fig trees and “dinosaur egg” in Allerton Garden (2021) We have a favorite travel destination, the Kauai Island in Hawai’i. Our first visit to Kauai was in 2007, and we really, really like it. I went there more often than my family: I have been there seven times! (laughs) I enjoyed looking out to the west of Pacific Ocean at the end of the Waimea canyon and walking on the Ke’e beach at the east end of the Na Pali Trail. If there is a chance, I may think about living there after retirement. You could do worse than that! In fact, that might be the answer to the next question, which is: with all your work and family responsibilities, and everything that you are involved in, what do you do for fun? My interests include reading, like history, literature, and sci-fi books. I like sci-fi fictions and TV shows, such as “The Expanse” series, “The Peripheral” from last year, and the “Three-Body” TV series from China. For fun, I like ******** Crosstalk, which is a comic dialogue between two people. Every year I also like to pick cherries and nectarines from farms in Brentwood. Cherries and nectarines we picked from Brentwood farms. Because I use my phone or camera like a recorder, I took too many photos here and there, far more than truly memorable moments. Those photos are a big headache when compiling a family yearbook. After our first child was born, it’s great fun to make annual photobooks for each year. It’s wonderful that you do that. That will pay dividends in the future, for sure. Before the pandemic, I also liked to have lunch together with a few colleagues every couple of weeks in some ******** restaurants nearby, and most of the time we order spicy ******** food. You like that? I like that too, although not too spicy! What has been a prime inspiration for you in your life? Something that motivated you to accomplish all that you’ve accomplished so far. Is there a person that you particularly liked? Drake, for example, and his work, that helped to inspire you going forward? A major motivation has been my curiosity about nature and stars. For inspirational figures, there were many – yes, Dr. Drake was one, because his work inspired people to think more seriously about the relation between life and the universe, and motivated me to make my own contributions. There was also inspiration from Professor Lee. After he won the chemistry Nobel Prize in 1986, there was a lot of laser chemistry related research going on in China. That’s what inspired me too, and why I asked him for advice. This has been wonderful. I’ve learned a lot about you and that is the whole purpose of this series. Thank you very much. We’ve enjoyed chatting with you. Thank you. It is great to have this opportunity to chat with you, I enjoyed it too. View the full article

What to Look for in July The scorpion’s star clusters, and Mars reveals elusive Uranus Follow the tail of Scorpius to locate star clusters M6 and M7, let Mars guide you to observe planet Uranus, and see the Moon gather a group of planets in the morning. Highlights All month – Two easy-to-spot star clusters – M7, aka Ptolemy’s Cluster, and M6, the Butterfly Cluster – are both located about 5 degrees east of the the bright stars that mark the “stinger” end of the scorpion’s tail. They reach their highest point in the sky around 10 or 11 pm local time. July 2 & 3 – The crescent Moon will join Jupiter and Mars in the east before sunrise. Looking for them before the sky starts to brighten, you’ll also find the Pleiades star cluster above Jupiter, and bright stars Capella and Aldebaran nearby. July 5 – New moon July 7 & 8 – Those with an unobstructed view of the western horizon can spot Mercury shining brightly, low in the sky with a slim crescent Moon. Look for them starting 30 to 45 minutes after the Sun sets. July 13 – For the first few hours after dark, look to the southwest to find the first-quarter Moon snuggled up to bright bluish-white star Spica. For much of the lower 48 U.S. and most of Mexico, the Moon will appear to pass in front of Spica – an event called an occultation. Check your favorite skywatching app for the view from your location. July 14-16 – Grab your binoculars and have a look at Mars in the early morning before the sky starts to brighten, and you’ll find the distant planet Uranus quite close by. July 21 – Full moon July 30 – Look for a close gathering of Jupiter, Mars, and the Moon with the bright stars of the constellation Taurus in the a.m. sky before dawn. Sky chart showing the position of Uranus relative to Mars on July 15. NASA/JPL-Caltech Transcript What’s Up for July? The Moon gets the band back together, find planet Uranus with some help from Mars, and the star clusters that feel the Scorpion’s sting. All month in July, as in June, the planetary action is in the a.m. sky. Find Saturn rising around midnight, and climbing high into the south by sunrise. Mars rises a couple of hours later, with Jupiter trailing behind it, and shifting higher in the sky each day. On July 2nd and 3rd before sunrise, the crescent Moon will join Jupiter and Mars in the east. Looking for them before the sky starts to brighten, you’ll also find the Pleiades star cluster above Jupiter, as well as bright stars Capella and Aldebaran. As the Moon swings around the planet in its orbit, this same group gets back together at the end of the month, but as a much tighter gathering of Jupiter, Mars, and the Moon with the bright stars of the constellation Taurus. Sky chart showing the pre-dawn sky on July 30, with Jupiter, Mars, and the crescent Moon, plus several bright stars in the constellation Taurus. NASA/JPL-Caltech Then on the evening of July 7th and 8th, those with an unobstructed view of the western horizon can spot Mercury shining brightly, low in the sky with a slim crescent Moon. Look for them starting 30 to 45 minutes after the Sun sets. Observers in the Southern Hemisphere will find Mercury a good bit higher in the northwest sky all month after sunset. On July 13, for the first few hours after dark, look to the southwest to find the first quarter Moon snuggled up to bright bluish-white star Spica. For much of the lower 48 ******* States and most of Mexico, the Moon will appear to pass in front of Spica – an event called an occultation. Next, over three days in mid-July, grab your binoculars and have a look at Mars in the early morning before the sky starts to brighten, and you’ll find the distant planet Uranus quite close by. Uranus is not too difficult to see with binoculars or a small telescope anytime it’s reasonably high above the horizon at night, but you really need to know where to look for it, or use an auto-guided telescope. But occasionally the Moon or one of the brighter planets will pass close to Uranus in the sky, making for a great opportunity to find it with ease. This sky chart shows the evening sky in July, with constellation Scorpius low in the south. The locations of star clusters M6 and M7 are indicated near the mythical scorpion’s tail. NASA/JPL-Caltech The winding form of constellation Scorpius, adorned with the bright red star Antares, is a feature of the night sky around the world this time of year. And at the tip of the scorpion’s tail are two well-known star clusters that are well placed for viewing at this time of year. M7, aka Ptolemy’s Cluster, and M6, the Butterfly Cluster, are both located about 5 degrees east of the the bright stars that mark the “stinger” end of the scorpion’s tail. They reach their highest point in the sky around 10 or 11 pm local time. To find M7, imagine a line toward the east through the “stinger stars,” Lesath and Shaula, and it will lead you straight to the star cluster. M6 is just a couple of degrees above M7. Both are “open star clusters,” meaning they’re loose groupings of stars that formed together, in the same region of space, and they’re only loosely bound together by gravity, so they’ll eventually go their separate ways. Zoomed sky chart showing where M7 and M6 are located relative to the bright stars that form the stinger of the scorpion constellation. Both are 5-6 degrees west of Shoala and Lesath, with M6 being placed about 5 degrees above, or north of, M7. NASA/JPL-Caltech M7 is just visible to the unaided eye under dark skies as a hazy patch just left of the tip of the scorpion’s tail. But it’s best seen with binoculars or a telescope with a wide field of view. Its stars are located at a distance of about 1000 light years from us, and they formed about 200 million years ago. The cluster was discovered by Greek-Roman astronomer Ptolemy in the year 130, hence its other name. M6 is about half the apparent size of M7, and contains fewer stars. It’s also a bit farther away from us, at around 1600 light years. It’s estimated to be about half as old as M7, at an age of around 100 million years. It was discovered by Italian astronomer and contemporary of Galileo, Giovanni Battista Hodierna, in 1654. These two clusters are easy to observe in July, and their location in Scorpius makes them pretty straightforward to locate on a clear night. So there’s no reason to ***** of this scorpion’s sting. Instead, let it guide you to two distant star clusters, and see for yourself two little families of stars in the process of spreading out into the Milky Way. Here are the phases of the Moon for July.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept depicts an asteroid drifting through space. Many such objects frequently pass Earth. To help prepare for the discovery of one with a chance of impacting our planet, NASA leads regular exercises to figure out how the international community could respond to such a threat.NASA/JPL-Caltech The fifth Planetary Defense Interagency Tabletop Exercise focused on an asteroid impact scenario designed by NASA JPL’s Center for Near Earth Object Studies. A large asteroid impacting Earth is highly unlikely for the foreseeable future. But because the damage from such an event could be great, NASA leads hypothetical asteroid impact “tabletop” exercises every two years with experts and decision-makers from federal and international agencies to address the many uncertainties of an impact scenario. The most recent exercise took place this past April, with a preliminary report being issued on June 20. Making such a scenario realistic and useful for all involved is no small task. Scientists from the Center for Near Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory in Southern California, which specializes in the tracking and orbital determination of asteroids and comets and finding out if any are hazards to Earth, have played a major role in designing these exercises since the first 11 years ago. “These hypothetical scenarios are complex and take significant effort to design, so our purpose is to make them useful and challenging for exercise participants and decision-makers to hone their processes and procedures to quickly come to a plan of action while addressing gaps in the planetary defense community’s knowledge,” said JPL’s Paul Chodas, the director of CNEOS. The Impact Scenario This year’s scenario: A hypothetical asteroid, possibly several hundred yards across, has been discovered, with an estimated 72% chance of impacting Earth in 14 years. Potential impact locations include heavily populated areas in North America, Southern Europe, and North *******, but there is still a 28% chance the asteroid will miss Earth. After several months of being tracked, the asteroid moves too close to the Sun, making further observations impossible for another seven months. Decision-makers must figure out what to do. Explore asteroids and near-Earth objects in real-time 3D Leading the exercise was NASA’s Planetary Defense Coordination Office (PDCO), the Federal Emergency Management Agency Response Directorate, and the Department of State Office of Space Affairs. Over the course of two days in April, participants gathered at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, which hosted the event, to consider the potential national and global responses to the scenario. “This was a very successful tabletop exercise, with nearly 100 participants from U.S. government agencies and, for the first time, international planetary defense experts,” said Terik Daly from APL, who coordinated the exercise. “An asteroid impact would have severe national and international ramifications, so should this scenario play out for real, we’d need international collaboration.” Reality Informs Fiction In real life, CNEOS calculates the orbit of every known near-Earth object to provide assessments of future potential impact hazards in support of NASA’s planetary defense program. To make this scenario realistic, the CNEOS team simulated all the observations in the months leading up to the exercise and used orbital determination calculations to simulate the probability of impact. “At this point in time, the impact was likely but not yet certain, and there were significant uncertainties in the object’s size and the impact location,” said Davide Farnocchia, a navigation engineer at JPL and CNEOS, who led the design of the asteroid’s orbit. “It was interesting to see how this affected the decision-makers’ choices and how the international community might respond to a real-world threat 14 years out.” Options to Deflect Preparation, planning, and decision-making have been key focal points of all five exercises that have taken place over the past 11 years. For instance, could a reconnaissance spacecraft be sent to the asteroid to gather additional data on its orbit and better determine its size and mass? Would it also be feasible to attempt deflecting the asteroid so that it would miss Earth? The viability of this method was recently demonstrated by NASA’s Double Asteroid Redirection Test (DART), which impacted the asteroid moonlet Dimorphos on Sept. 26, 2022, slightly changing its trajectory. Other methods of deflection have also been considered during the exercises. But any deflection or reconnaissance mission would need many years of preparation, requiring the use of advanced observatories capable of finding hazardous asteroids as early as possible. NASA’s Near-Earth Object Surveyor, or NEO Surveyor, is one such observatory. Managed by JPL and planned for launch in late 2027, the infrared space telescope will detect light and dark asteroids, including those that orbit near the Sun. In doing so, NEO Surveyor will support PDCO’s objectives to discover any hazardous asteroids as early as possible so that there would be more time to launch a deflection mission to potential threats. To find out the outcome of the exercise, read NASA’s preliminary summary.

NASA astronaut Mike Barratt processes brain organoid samples inside the life science glovebox for a neurodegenerative disorder study. NASA plans to use future commercial low Earth orbit destinations for the continuation of scientific research.NASA NASA hosted a meeting to share knowledge with companies developing future commercial destinations at the agency’s Johnson Space Center in Houston. The discussion could aid in developing safe, reliable, innovative, and cost-effective space stations. Industry representatives from more than 20 companies attended. The program focused on NASA’s planned use of commercial destinations, draft utilization requirements, and the payload life cycle. A primary interest for the use of commercial stations includes the continuation of scientific research in low Earth orbit, such as human research, technology demonstrations, biological and physical science, and Earth observation. David Caponio from Vast Space presents a five-minute lightning talk on the company’s capabilities during the program NASA’s Johnson Space Center. Vast is working with NASA under the second Collaborations for Commercial Space Capabilities initiative for technologies and operations required for its microgravity and artificial gravity stations, including the Haven-1 commercial destination.NASA/Josh Valcarcel “NASA has benefited from the unique microgravity environment of low Earth orbit to conduct important science investigations and technology demonstrations for more than two decades,” said Dr. Kirt Costello, utilization manager for NASA’s Commercial Low Earth Orbit Development Program. “As commercial companies make progress in the design and development of their own space stations, it is important that we share NASA’s needs and requirements as well as foster an open dialogue between government and private industry.” The program builds on a request for information released last year, seeking feedback from industry as the agency refines its requirements for new commercial space destinations. Vergel Romero of Sierra Space speaks with representatives from other commercial companies during a networking opportunity. Sierra Space is working with Blue Origin on the development of Orbital Reef, and also holds an unfunded Space Act Agreement with NASA for the development of its commercial low Earth orbit ecosystem.NASA/Josh Valcarcel Since then, the feedback has helped develop and refine a utilization requirements strategy, including a concept of operations, basic laboratory capabilities, and common payload standards for heritage hardware. NASA will continue to refine its future requirements and incorporate future low Earth orbit needs of other U.S. government agencies and international partners. NASA uses a two-phase strategy to support the development of commercial destinations and enable the agency to purchase services as one of many customers. Phase 1 efforts extend through 2025, before NASA plans to transition to Phase 2, which will be to certify commercial destinations and purchase services. Eleasa Kim, payload operations lead for NASA’s Commercial Low Earth Orbit Development Program, presents on NASA’s planned utilization activities for commercial destinations and expectations for provider support.NASA/Josh Valcarcel The agency’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost and enable the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

4 Min Read NASA’s Webb Captures Celestial Fireworks Around Forming Star L1527, shown in this image from NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument). The colors within this mid-infrared image reveal details about the central protostar’s behavior. The cosmos seems to come alive with a crackling ********** of pyrotechnics in this new image from NASA’s James Webb Space Telescope. Taken with Webb’s MIRI (Mid-Infrared Instrument), this fiery hourglass marks the scene of a very young object in the process of becoming a star. A central protostar grows in the neck of the hourglass, accumulating material from a thin protoplanetary disk, seen edge-on as a dark line. The protostar, a relatively young object of about 100,000 years, is still surrounded by its parent molecular cloud, or large region of gas and dust. Webb’s previous observation of L1527, with NIRCam (Near-Infrared Camera), allowed us to peer into this region and revealed this molecular cloud and protostar in opaque, vibrant colors. Image A: L1527 – Webb/MIRI L1527, shown in this image from NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument), is a molecular cloud that harbors a protostar. It resides about 460 light-years from Earth in the constellation Taurus. The more diffuse blue light and the filamentary structures in the image come from organic compounds known as polycyclic aromatic hydrocarbons (PAHs), while the red at the center of this image is an energized, thick layer of gases and dust that surrounds the protostar. The region in between, which shows up in white, is a mixture of PAHs, ionized gas, and other molecules. This image includes filters representing 7.7 microns light as blue, 12.8 microns light as green, and 18 microns light as red. Both NIRCam and MIRI show the effects of outflows, which are emitted in opposite directions along the protostar’s rotation axis as the object consumes gas and dust from the surrounding cloud. These outflows take the form of bow shocks to the surrounding molecular cloud, which appear as filamentary structures throughout. They are also responsible for carving the bright hourglass structure within the molecular cloud as they energize, or excite, the surrounding matter and cause the regions above and below it to glow. This creates an effect reminiscent of fireworks brightening a cloudy night sky. Unlike NIRCam, however, which mostly shows the light that is reflected off dust, MIRI provides a look into how these outflows affect the region’s thickest dust and gases. The areas ******** here in blue, which encompass most of the hourglass, show mostly carbonaceous molecules known as polycyclic aromatic hydrocarbons. The protostar itself and the dense blanket of dust and a mixture of gases that surround it are represented in red. (The sparkler-like red extensions are an artifact of the telescopes’s optics). In between, MIRI reveals a white region directly above and below the protostar, which doesn’t show as strongly in the NIRCam view. This region is a mixture of hydrocarbons, ionized neon, and thick dust, which shows that the protostar propels this matter quite far away from it as it messily consumes material from its disk. As the protostar continues to age and release energetic jets, it’ll consume, ********, and push away much of this molecular cloud, and many of the structures we see here will begin to fade. Eventually, once it finishes gathering mass, this impressive display will end, and the star itself will become more apparent, even to our visible-light telescopes. The combination of analyses from both the near-infrared and mid-infrared views reveal the overall behavior of this system, including how the central protostar is affecting the surrounding region. Other stars in Taurus, the star-forming region where L1527 resides, are forming just like this, which could lead to other molecular clouds being disrupted and either preventing new stars from forming or catalyzing their development.The James Webb Space Telescope is the world’s premier space science observatory.
