Rebekah Hounsell is an assistant research scientist working on ways to optimize and build infrastructure for future observations made by the Nancy Grace Roman Space Telescope. The mission will shed light on many astrophysics topics, like dark energy, which are currently shrouded in mystery. Rebekah also works as a support scientist for the TESS (Transiting Exoplanet Survey Satellite) mission, helping scientists access and analyze data. Name: Rebekah Hounsell Title: Assistant Research Scientist Formal Job Classification: Support Scientist for the TESS mission and Co-Principal Investigator of the Roman Supernova Project Infrastructure Team (PIT) Organization: Code 667.0 Rebekah Hounsell knew she wanted to study space from a very young age. Now, she’s a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. NASA/Chris Gunn What do you do and what is most interesting about your role at Goddard? I am fortunate to have several roles at Goddard. I am a support scientist for TESS. Here I aid the community in accessing and analyzing TESS data. I am a co-principal investigator of a Roman project infrastructure team, focusing on building infrastructure to support supernova cosmology with the Roman HLTDS (High Latitude Time-Domain Survey). In addition, I am part of the Physics of the Cosmos program analysis group executive committee, co-chairing both the Cosmic Structure Science interest group and the Time-Domain and Multi-Messenger Astrophysics Science interest group. In these roles I have been fortunate enough to get a glimpse into how missions such as TESS and Roman work and how we can make them a success for the community. Missions like TESS are paving the way for future wide area surveys like Roman, providing a plethora of high cadence transient and variable star data, which can be used to gain a better understanding of our universe and our place within it. How will your current work influence the Nancy Grace Roman Space Telescope’s future observations? The Roman team I am leading is tasked with developing a pixels-to-cosmology pipeline for the analysis of supernova data from the HLTDS. What this means is that we will develop tools to aid the community in obtaining supernova lightcurves and prism spectra, which are precise enough to be used in testing various cosmological modes. We are also working to develop tools which will allow the community to test various HLTDS designs, adjusting cadence, filters, exposure times, etc., to best optimize its output for their science. What got you interested in astrophysics? What was your path to your current role? When I was a child I lived in a very rural area in England, with little to no light pollution. I had a wonderful view of the night sky and was fascinated by stars. I remember when I found out that the universe was expanding and my first thought was “into what?” I think it was that which fueled my curiosity about space and pushed me into astrophysics. At about 10 years old, I decided astrophysics was the path for me, and after that I really started to focus on physics and math at school. At 18, 19 I went to Liverpool University/Liverpool John Moores and completed my master’s in astrophysics in 2008. I then went on to obtain my Ph.D., focusing on classical and recurrent novae. In 2012 I received my first postdoc at STScI (the Space Telescope Science Institute in Baltimore). It was at STScI that I learned about how the instruments operating on Hubble worked and figured out that what I really loved doing was working on data and improving it. At the time however, I wasn’t ready to leave academia altogether, so I took another postdoc at the University of Illinois Champaign Urbana/UC Santa Cruz. It was here that I first started working on Roman, only back then it was known as WFIRST. I was a member of a Supernova Science Investigation Team for WFIRST and worked to optimize the design of what was then known as the SN survey, later to become the HLTDS. During this time I published a paper that created some of the most realistic simulations of the survey, including various statistical and systematic effects. After this I headed to the University of Pennsylvania to work on core collapse supernovae from the Dark Energy Survey. This was an exciting data set, but again I realized what I really liked doing was working on data from or for a mission. As such I took my current job at NASA. Rebekah stands by a model of NASA’s upcoming Nancy Grace Roman Space Telescope. The observatory’s deployable aperture cover, or sun shade, is visible in the background in the largest clean room at Goddard.NASA/David Friedlander What are you most looking forward to exploring through Roman’s eyes? Given the nature of the mission, Roman is going to discover a plethora of transient events. Some of these will be extremely rare and if caught in one of Roman’s high cadenced, deep fields, the data obtained will be able to shed new light on the physics driving these phenomena. I am also excited about these data being used with those from other observatories including the Vera C. Rubin Observatory and NASA’s James Webb Space Telescope. What has surprised you the most about the universe as you’ve learned more about it? We are still discovering so many new things which shed new light on the universe, its evolution, and our place in it. In recent years we have learned about kilonovae, gravitational waves, and we’ve discovered various diverse supernovae. There are so many extreme and complex events that we are still trying to understand, and I suspect that Roman will reveal even more. What is your favorite thing about working for NASA? There is no one path to working at NASA. I have met so many people who entered into the field following completely different paths than myself. I love this. We all have something different to bring to the table and those differences are what makes NASA what it is today. A portrait of Rebekah in front of the NASA meatball.NASA/David Friedlander What hobbies fill your time outside of work? I like to paint and draw. I also enjoy looking after animals. I also love participating in outreach events. When I lived in Philly I helped to set up the Astronomy on Tap branch there. I think it is important to talk about what we do and why it is needed. What advice do you have for others who are interested in working in astronomy? There is no one path. Don’t think you have to complete x, y, z steps and then you make it. That is not true. Do what you are passionate about, what you enjoy to learn about. And most importantly ask questions! Learn about what others are doing in the field, how they got there, and figure out what works for you. By Ashley Balzer NASA’s Goddard Space Flight Center, Greenbelt, Md.

Credit: NASA The ******* States and Saudi Arabia signed a framework agreement that opens new possibilities for cooperation with NASA in areas such as space science, exploration, aeronautics, space operations, education, and Earth science. NASA Administrator Bill Nelson signed on behalf of the U.S., and CEO of the Saudi Space Agency Mohammed bin Saud Al-Tamimi signed on behalf of the Kingdom of Saudi Arabia. “Building on my visit to Saudi Arabia earlier this year, I look forward to strengthening our cooperation for the future of exploration,” said Nelson. “We are living in the golden era of exploration – one that is rooted in partnership. This new agreement outlines how we’ll work together, and explore together, for the benefit of humanity.” Known as the “Framework Agreement Between the Government of the ******* States of America and the Government of The Kingdom of Saudi Arabia on Cooperation in Aeronautics and the Exploration and Use of Airspace and Outer Space for Peaceful Purposes,” it establishes the overall legal framework to facilitate and strengthen mutually beneficial collaboration between the two countries. “The agreement represents a turning point in the Kingdom’s journey towards building a strong and prosperous space sector,” said Saudi Space Agency Chairman Abdullah bin Amer Al-Swaha. “It reflects the Kingdom’s firm commitment to progress and innovation in the field of space, and its continuous efforts to enhance its position as an important partner on the global stage for space exploration and scientific discovery.” The agreement also acknowledges the importance of the Artemis Accords, which Saudi Arabia signed in July 2022, for the transparent, safe, and responsible exploration of space. The commitments of the Artemis Accords, and efforts by the signatories to advance implementation of all its principles, support NASA’s Artemis campaign with its partners and other activities of the accords signatories. The signing comes two months after Nelson’s visit to Saudi Arabia, where he met with Saudi Space Agency and other senior officials to discuss future partnerships and civil space cooperation for the broader U.S. and Saudi Arabia relationship. In May 2023, two Saudi mission specialists, Ali Alqarni and Rayyanah Barnawi, were among a group of Axiom Mission-2 private astronauts who launched into orbit aboard a SpaceX Dragon from NASA’s Kennedy Space Center in Florida, highlighting international cooperation. The Axiom Space astronauts conducted scientific research, outreach, and commercial activities aboard the International Space Station.

4 Min Read Prepare for Perseids! A view of the 2023 Perseid meteor shower from the southernmost part of Sequoia National Forest, near Piute Peak. Credits: NASA/Preston Dyches Are you ready for the 2024 Perseids? Their peak is expected to be on the night of August 11 through the morning of the 12th, with good seeing to be had the nights before and after. You may have already spotted a few Perseids streaking across the summer skies! This shower, part of the debris stream of comet Swift-Tuttle, actually starts in mid to late July and lasts through most of August. While most of these nights only showcase a few meteors each hour, the peak of the Perseids brings many, many more. How much more? The number actually varies every year; there can be as little as a few dozen per hour, but some rare years bring a brief “burst’ of up to two hundred beautiful “********* stars” an hour. Image of a Perseid meteor streaking over Joshua Tree National Park. Brad Sutton/National Parks Service This year’s Perseids will be slightly impacted by a 53% waxing Moon, but the Moon will set right as the Perseids begin to peak! This means that if you are in an area free from light pollution and enjoy clear skies, you may be able to see quite a few meteors over the course of the night! How many will you be able to see? There’s only one way to find out for yourself how strong the Perseids will be this year: go outside and patiently watch! We have a few tips on how to make the most of your meteor shower viewing experience: If you trace the meteor trails of the Perseids back to their source, you will find they seem to come from a spot near the constellation Perseus – hence their name, and the name of most meteor showers. What’s Up: August 2023, NASA/JPL Get out of the city! Try to get to the darkest location you can. The darker it is where you are, the more meteors you will see streaking across the sky. Check the weather forecast for that night. You may need to check out two or three areas for predictions on fog, clouds, and temperature. Some weather sites even offer forecasts specially tailored for sky watching. Make sure you have clear skies to go along with those dark ones. Find a meteor shower party! Go to a gathering of like-minded folks in a local park, or an event hosted by a local astronomy club – especially if it’s your first time! Find a Perseids party by searching the Night Sky Network for clubs near you, or by searching for events near you Stay warm and comfortable outside-be prepared! You will be out for a good long while and will want to lie flat on your back to soak up as much of the sky as possible. To stay cozy, bring a blanket, jacket, hat, a warm drink, and water. You may think it’s silly to bring some warm clothes in the middle of the summer, but late at night the temperature can drop just enough to be chilly. If you are in a buggy area, you will want to apply some bug spray to avoid irritating bites Bring your friends and family! Company under starry skies is wonderful, and they provide a bonus since there are more eyes on the sky! Groups can spot more meteors than single individuals and help each other find ‘hot spots” in the sky. (Also- if you are out in the wilderness in the dark, good company helps you feel safer.) For more information on one of our favorite meteor showers, check out NASA’s Perseid page and EarthSky’s great observing guide. You should also check out JPL’s August 2023 “What’s Up? video as Preston Dyches offers great tips on how to watch for the Perseids, as well as other objects to look for in the night skies while you wait for these brilliant streaks. You can also use NASA’s “Fluximator” meteor shower activity application to try to predict when the peak activity will be for your location. We also have a handout you can use at your star parties and outreach events: Heads up! It’s a Meteor Shower resource page. Have fun and may you have clear skies and great weather for your meteor shower party! Originally posted by Dave Prosper: August 2018 Last Updated by Kat Troche: May 2024 View the full article

A portrait of Dorothy Vaughan, a mathematician, computer programmer, and NASA’s first ****** manager.Credit: NASA NASA’s Johnson Space Center in Houston will recognize legendary human computer Dorothy Vaughan and the women of Apollo with activities marking their achievements, including a renaming and ribbon-cutting ceremony at the center’s “Building 12,” on Friday, July 19, the eve of the 55th anniversary of the Apollo 11 Moon landing. At 9 a.m. CDT, NASA Johnson Director Vanessa Wyche will begin with a discussion about the importance of Vaughan and the women of Apollo’s contributions to the agency’s lunar landing program and their significance to today’s Artemis campaign. Other highlights include a poetry reading, a recital by Texas Southern University’s Dr. Thomas F. Freeman Debate Team, and a “Women in Human Spaceflight” panel discussion. The panel in NASA Johnson’s Teague Auditorium will be moderated by Debbie Korth, the agency’s Orion Program deputy manager, and include: Christina Koch, NASA astronaut Sandy Johnson, Barrios Technology CEO Lara Kearney, NASA Extravehicular Activity and Human Surface Mobility Program manager Andrea Mosie, NASA Lunar Materials Repository Laboratory manager and senior sample processor Dr. Shirley Price, former NASA Equal Opportunity specialist Following the program, the ribbon-cutting ceremony will begin at Building 12, which will thereafter be named the “Dorothy Vaughan Center in Honor of the Women of Apollo.” The dedication is a tribute to the people who made humanity’s first steps on the Moon possible. All interested media must request credentials by 12 p.m. Thursday, July 18, by email at *****@*****.tld or by calling the Johnson newsroom at 281-483-5111. Media should arrive onsite for setup by 8:15 a.m. July 19, at the Teague Auditorium in Building 2 South. U.S. media are invited to attend and will have an opportunity to ask questions during the panel discussion and may request brief interviews with available NASA officials following the ribbon cutting. Distinguished guests are expected to include local elected officials, NASA senior leadership, members of NASA’s Alumni League, and the families of Dorothy Vaughan and the women of Apollo. “On behalf of NASA’s Johnson Space Center, we are proud to host this historic event as the agency honors the significant contributions women have made to the space industry, particularly trailblazers who persevered against many challenges of their era,” Wyche said. “As we prepare to return to the Moon for long-term science and exploration, NASA’s Artemis missions will land the first woman and first person of ****** on the Moon. It’s a privilege to dedicate Johnson’s Building 12 to the innovative women who ***** the foundation to our nation’s space program.” Vaughan’s personal commitment and determination during the Apollo missions advanced the agency’s current diverse workforce and leadership – particularly at Johnson — as human computers transitioned from Langley Research Center in Virginia to Houston, supporting Mission Control from Building 12. She was a steadfast advocate for the women who worked as human computers, and for all the individuals under her leadership.

On July 15, 2009, space shuttle Endeavour began its 23rd trip into space, on the 2JA mission to the International Space Station, the 29th shuttle flight to the orbiting lab. During the 16-day mission, the seven-member STS-127 crew, working with Expedition 20, the first six-person crew aboard the station, completed the primary objectives of the mission. The flight marked the first time 13 people worked about the station at the same time. They added the Exposed Facility (EF) to the Kibo ********* Experiment Module (JEM), including its first three payloads, and performed a crew exchange of long-duration crew members. The tasks involved five complex space walks and extensive robotic activities using three different manipulator systems during 11 days of docked operations. Left: The STS-127 crew patch. Middle: Official photograph of the STS-127 crew of David A. Wolf, left, Christopher J. Cassidy, Douglas G. Hurley, Julie Payette of Canada, Mark L. Polansky, Thomas H. Marshburn, and Timothy L.

Middle: The STS-127 payloads in Endeavour’s cargo bay at Launch Pad 39A at NASA’s Kennedy Space Center in Florida. Right: Space shuttle Endeavour on Launch Pad 39A a few days before launch. Endeavour returned from its previous mission, STS-126, on Nov. 28, 2008. It arrived in the Orbiter Processing Facility at NASA’s Kennedy Space Center (KSC) on Dec. 13, moved to the Vehicle Assembly Building on April 10, 2009, and rolled out to Launch Pad 39B seven days later to serve as the Launch on Need vehicle for STS-125 in May 2009. When that mission flew without issues, on May 31, workers rolled Endeavour around to Pad 39A to begin preparations for STS-127, planned for launch on June 13. A gaseous hydrogen ***** scrubbed this first launch attempt. A similar ***** halted the second attempt on June 17 and managers reset the launch date to July 11. Managers scrubbed that launch when 11 lightning strikes struck the launch pad area, requiring a review of Endeavour’s and ground systems. With the seven-member crew aboard Endeavour, weather once again halted the launch attempt on July 12. They tried again the next day, but weather conditions led to a fifth scrubbed launch attempt. The charm came on the sixth try. Liftoff of space shuttle Endeavour on STS-127 carrying the Exposed Facility for the ********* Kibo module. On July 15, 2009, at 6:03 p.m. EDT, space shuttle Endeavour lifted off from KSC’s Launch Pad 39A to begin its 23rd trip into space, beginning the 2JA mission to the space station. Eight and a half minutes later, Endeavour and its crew had reached orbit. This marked Wolf’s fourth time in space, Polansky’s third, Payette’s second, while Hurley, Cassidy, Marshburn, and Kopra enjoyed their first taste of true weightlessness.

On July 17, the 34th anniversary of the Apollo-Soyuz Test Project docking, Polansky assisted by his crewmates brought Endeavour in for a docking with the space station. During the rendezvous, Polansky stopped the approach at 600 feet and completed the Rendezvous Pitch Maneuver so astronauts aboard the station could photograph Endeavour’s underside to look for any damage to the tiles. Shortly after docking, the crews opened the hatches between the two spacecraft and the six-person station crew welcomed the seven-member shuttle crew. Expedition 20 Commander Gennady I. Padalka of Roscosmos stated, “This is a remarkable event for the whole space program.” Polansky responded, “Thirteen is a big number, but we are thrilled to be here.” After exchanging Soyuz seat liners, Kopra joined the Expedition 20 crew and Wakata the STS-127 crew.

STS-127 marked not only the first time that a space shuttle arrived at the station with a six-person crew living aboard, but as it happened, each of the five space station partners had a crew member aboard, a feat not repeated since. The flight also marked the first time that two CSA astronauts worked aboard the space station at the same time. And for the true trivia buffs, the mission marked the first time that four medical doctors worked in space together – an out of this world medical convention!

On July 18, the mission’s fourth day, Hurley and Wakata grappled the JEM-EF using the Space Station Remote Manipulator System (SSRMS) or robotic arm, handed it off temporarily to the SRMS operated by Polansky and Payette, moved the station arm into position to grapple it again, and installed it on the end of the Kibo module. Meanwhile, Wolf, with red stripes on his spacesuit, and Kopra, wearing a suit with no stripes, began the mission’s first spacewalk. During the excursion that lasted 5 hours 32 minutes, Wolf and Kopra prepared the JEM for the EF installation and performed other tasks in the shuttle’s payload bay and on the station.

Prior to the start of the spacewalk, Hurley and Payette used the station’s arm to relocate the ICC to a different workstation for Wolf and Cassidy to transfer the batteries to the station. As their first task, Wolf and Cassidy prepared the JEM EF for the transfer of the three payload the following day. They managed to transfer two of the four batteries before mission managers decided to shorten the spacewalk due to a slight buildup of carbon dioxide in Cassidy’s suit.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) HyAxiom’s 440-kilowatt phosphoric acid fuel cell is now its flagship product, and it still builds on technical know-how developed under the Apollo and space shuttle programs.Credit: HyAxiom Inc. NASA’s investment in fuel cells dates to the 1960s when most of the world was still reliant on fossil fuels. A fuel cell generates electricity and heat when hydrogen and oxygen bond through an electrolyte. Because its only by-product is water, it’s an environmentally friendly power source. The agency’s interest in fuel cells came when NASA needed to fuel missions to the Moon. Engineers at NASA’s Johnson Space Center in Houston looked to fuel cells because they could provide more energy per pound than batteries could over the course of a long mission. At that time, fuel cells were just a concept that had never been put to practical use. NASA funded development of the first practical fuel cells because they were necessary to cut weight from the Apollo spacecraft for Moon missions. Three fuel cells in the Apollo service module provided electricity for the capsule containing the astronauts. The division of Pratt & Whitney that made the fuel cells later became UTC Power, now a subsidiary of Doosan Group known as HyAxiom Inc.Credit: NASA NASA funded three companies, including a portion of Pratt & Whitney, to develop prototypes. For Apollo mission fuel cells, NASA selected the Pratt & Whitney group, which soon became UTC Power, as the supplier of all the space shuttle fuel cells. With the agency funding and shaping its technology development, UTC Power eventually started offering commercial fuel cells. The company is now known as HyAxiom Inc. and operates from the same plant in South Windsor, Connecticut, that produced fuel cells for the agency. The company released its first commercial fuel cell in the mid-1990s and introduced its current product line about a decade later. “The models they built for these products we use today had a lot of the electrochemistry understanding from the space program,” said Sridhar Kanuri, HyAxiom’s chief technology officer. HyAxiom now produces around 120 units per year but expects to ramp up as government investments in fuel cells increase. The U.S. government plans to use fuel cells to store energy from renewable sources. Today’s commercial fuel cell companies received much of their knowledge base from NASA. John Scott, NASA’s principal technologist for power and energy storage said, “All these companies trace their intellectual property heritage, their corporate heritage, even the generations of personnel to those companies NASA funded back in the early 1960s.” Read More Share Details Last Updated Jul 15, 2024 Related TermsTechnology Transfer & SpinoffsApolloJohnson Space CenterSpinoffsTechnology Transfer Explore More 2 min read Sky High Sustainability: NASA Johnson’s Pocket Prairie Flourishes Atop Building 12 Article 6 hours ago 6 min read Voyagers of Mars: The First CHAPEA Crew’s Yearlong Journey Article 4 days ago 5 min read From Polar Peaks to Celestial Heights: Christy Hansen’s Unique Path to Leading NASA’s Commercial Low Earth Orbit Development Program Article 6 days ago Keep Exploring Discover Related Topics The Apollo Program Technology Transfer & Spinoffs Exploring the Moon Technology View the full article

From left, team members Annie Meier, Malay Shah, and Jamie Toro assemble the flight hardware for NASA’s Orbital Syngas Commodity Augmentation Reactor, or OSCAR, on Oct. 10, 2019, in the Space Station Processing Facility at the agency’s Kennedy Space Center in Florida. OSCAR began as an Early Career Initiative project at the spaceport that studies technology to convert trash and human waste into useful gasses such as methane, hydrogen, and carbon dioxide. NASA/Cory Huston There’s no “I” in team, and that holds true for NASA and its partners as the agency ramps up efforts to recruit tenured professors to research science for a semester at the agency’s Kennedy Space Center in Florida. The tenured teachers work for up to a year in an area where the agency needs specific expertise. NASA often finds tenured professors – someone who has been guaranteed a job with their university until they retire – through seminars or publications. Assignments must be mutually beneficial to the agency and organizations involved. “At NASA, we want researchers who are doing something that could help us, that could be synergistic, and to not reinvent the wheel,” said Dr. Jose Nuñez, University Partnerships and Small Sat Capabilities manager at NASA Kennedy. “The goal is to find professors who can benefit the agency in an area that needs more research.” The U.S. government’s Intergovernmental Personnel Act Mobility Program allows the temporary assignment of personnel between the federal, state, local governments, colleges and universities, Indian tribal governments, federally funded research and development centers, and other eligible organizations. Dr. Reza Toufiq, an associate professor of chemical engineering at Florida Institute of Technology in Melbourne, Florida, is the first professor to leverage school funds to spend a semester at NASA Kennedy and work on projects dealing with waste and resource recovery. Toufiq specializes in how to convert everyday trash into energy, including the ash or char left behind from thermally treated trash. He worked with Dr. Annie Meier, who leads a team that converts astronauts’ trash into gasses that can be used for fuel. Flight hardware for NASA’s Orbital Syngas Commodity Augmentation Reactor, or OSCAR, is inside the Applied Physics Lab inside the Neil Armstrong Operations and Checkout Facility at the agency’s Kennedy Space Center in Florida on July 21, 2022. By processing small pieces of trash in a high-temperature reactor, OSCAR is advancing new and innovative technology for managing waste in space. NASA/Kim Shiflett “I wanted to learn on the terrestrial side how we can infuse some of our technology, and he wanted to learn from us to grow into the space sector, so it was a really cool match,” said Meier, technical lead for situ resource utilization and waste management resource recovery systems at NASA Kennedy. Although Toufiq’s sabbatical with NASA is over, his work is not. Meier just received approval for a project through a Space Act Agreement, which allows a research sponsor to use NASA scientists and facilities to benefit both parties. Meier and other researchers at NASA will give Toufiq information on space waste products and lunar regolith stimulants; in turn, he will do the testing, and provide data to the agency because some of that information is currently unknown. “He’s learning a lot about the fundamentals of different things with waste that we aren’t really doing, so we lean on academia to get some of that information and offer a fresh perspective,” Meier said. An intergovernmental assignment is generally approved for up to two years, but it can extend for up to six years with authorization. The length of the appointment also depends on the agency’s needs and university’s sabbatical guidelines, which could pay for one or more semesters. The University Partnerships team now is working to bring on two professors to NASA Kennedy next semester. “There are many tenured professors and universities who would like to come here, but we are careful to use due diligence to make sure what they’re doing is something that aligns with our research and technology interests,” Nuñez said.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This illustration of the large Quetzalpetlatl Corona located in Venus’ southern hemisphere depicts active volcanism and a subduction zone, where the foreground crust plunges into the planet’s interior. A new study suggests coronae reveal locations where active geology is shaping Venus’ surface. The stars above and on Earth aligned as an inspirational message and lyrics from the song “The Rain (Supa Dupa Fly)” by hip-hop artist Missy Elliott were beamed to Venus via NASA’s DSN (Deep Space Network). The agency’s Jet Propulsion Laboratory in Southern California sent the transmission at 10:05 a.m. PDT on Friday, July 12. As the largest and most sensitive telecommunication service of NASA’s Space Communications and Navigation (SCaN) program, DSN has an array of giant radio antennas that allow missions to track, send commands, and receive scientific data from spacecraft venturing to the Moon and beyond. To date, the system has transmitted only one other song into space, making the transmission of Elliott’s song a first for hip-hop and NASA. “Both space exploration and Missy Elliott’s art have been about pushing boundaries,” said Brittany Brown, director, Digital and Technology Division, Office of Communications at NASA Headquarters in Washington, who initially pitched ideas to Missy’s team to collaborate with the agency. “Missy has a track record of infusing space-centric storytelling and futuristic visuals in her music videos so the opportunity to collaborate on something out of this world is truly fitting.” The song traveled about 158 million miles (254 million kilometers) from Earth to Venus — the artist’s favorite planet. Transmitted at the speed of light, the radio frequency signal took nearly 14 minutes to reach the planet. The transmission was made by the 34-meter (112-foot) wide Deep Space Station 13 (DSS-13) radio dish antenna, located at the DSN’s Goldstone Deep Space Communications Complex, near Barstow in California. Coincidentally, the DSS-13 also is nicknamed Venus. Elliott’s music career started more than 30 years ago, and the DSN has been communicating with spacecraft for over 60 years. Now, thanks to the network, Elliott’s music has traveled far beyond her Earth-bound fans to a different world. “I still can’t believe I’m going out of this world on tour with NASA through the Deep Space Network when “The Rain” (Supa Dupa Fly) becomes the first ever hip-hop song to transmit to space!,” said Elliott. “I chose Venus because it symbolizes strength, beauty, and empowerment and I am so humbled to have the opportunity to share my art and my message with the universe!” Two NASA missions, selected in 2021, will explore Venus and send data back to Earth using the DSN. DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging), led out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is slated to launch no earlier than 2029. The VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy), launching no earlier than 2031, is lead out of NASA’s Jet Propulsion Laboratory in Southern California. NASA and the DSN are also partnering with the ********* Space Agency’s Venus mission, Envision. A team at JPL is developing the spacecraft’s Venus Synthetic Aperture Radar (VenSAR). In continuous operations since 1963, NASA SCaN’s DSN is composed of three complexes spaced equidistant from each other — approximately 120 degrees apart in longitude — around the planet. The ground stations are in Goldstone in California, Madrid, and Canberra in Australia. The Deep Space Network is managed by JPL for the SCaN program within the Space Operations Mission Directorate, based at NASA Headquarters.

Painters work on the official NASA insignia, nicknamed “the meatball,” on the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on May 29, 2020.NASA/Kim Shiflett NASA’s official logo, nicknamed the “meatball,” turned 65 on July 15, 2024. The insignia dates back to 1959, when the National Advisory Committee on Aeronautics (NACA) metamorphosed into an agency that would advance both space and aeronautics: the National Aeronautics and Space Administration. After a NASA Lewis (now Glenn) Research Center illustrator’s design was chosen for the new agency’s official seal, the head of Lewis’ Research Reports Division, James Modarelli, was asked by the executive secretary of NACA to design a logo that could be used for less formal purposes. In the design, the sphere represents a planet, the stars represent space, the red chevron is a wing representing aeronautics (the latest design in hypersonic wings at the time the logo was developed), and then there is an orbiting spacecraft going around the wing. The red, white, and blue design, which includes elements representing NASA’s space and aeronautics missions, became the official logo of the ******* States’ new space agency in 1959.

6 Min Read NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World Artists concept of WASP-39 b (full image below). Near-infrared spectral analysis of terminator confirms differences in morning and evening atmosphere Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked to its parent star. This means it has a constant dayside and a constant nightside—one side of the planet is always exposed to its star, while the other is always shrouded in darkness. Using Webb’s NIRSpec (Near-Infrared Spectrograph), astronomers confirmed a temperature difference between the eternal morning and eternal evening on WASP-39 b, with the evening appearing hotter by roughly 300 Fahrenheit degrees (about 200 Celsius degrees). They also found evidence for different cloud cover, with the forever morning portion of the planet being likely cloudier than the evening. Image A: Artist Concept WASP-39 b This artist’s concept shows what the exoplanet WASP-39 b could look like based on indirect transit observations from NASA’s James Webb Space Telescope as well as other space- and ground-based telescopes. Data collected by Webb’s NIRSpec (Near-Infrared Spectrograph) show variations between the eternal morning and evening atmosphere of the planet. Astronomers analyzed the 2- to 5-micron transmission spectrum of WASP-39 b, a technique that studies the exoplanet’s terminator, the boundary that separates the planet’s dayside and nightside. A transmission spectrum is made by comparing starlight filtered through a planet’s atmosphere as it moves in front of the star, to the unfiltered starlight detected when the planet is beside the star. When making that comparison, researchers can get information about the temperature, composition, and other properties of the planet’s atmosphere. “WASP-39 b has become a sort of benchmark planet in studying the atmosphere of exoplanets with Webb,” said Néstor Espinoza, an exoplanet researcher at the Space Telescope Science Institute and lead author on the study. “It has an inflated, puffy atmosphere, so the signal coming from starlight filtered through the planet’s atmosphere is quite strong.” Previously published Webb spectra of WASP-39b’s atmosphere, which revealed the presence of carbon dioxide, sulfur dioxide, water vapor, and sodium, represent the entire day/night boundary – there was no detailed attempt to differentiate between one side and the other. Now, the new analysis builds two different spectra from the terminator region, essentially splitting the day/night boundary into two semicircles, one from the evening, and the other from the morning. Data reveals the evening as significantly hotter, a searing 1,450 degrees Fahrenheit (800 degrees Celsius), and the morning a relatively cooler 1,150 degrees Fahrenheit (600 degrees Celsius). Image B: Transmission Spectra “It’s really stunning that we are able to parse this small difference out, and it’s only possible due Webb’s sensitivity across near-infrared wavelengths and its extremely stable photometric sensors,” said Espinoza. “Any tiny movement in the instrument or with the observatory while collecting data would have severely limited our ability to make this detection. It must be extraordinarily precise, and Webb is just that.” Extensive modeling of the data obtained also allows researchers to investigate the structure of WASP-39 b’s atmosphere, the cloud cover, and why the evening is hotter. While future work by the team will study how the cloud cover may affect temperature, and vice versa, astronomers confirmed gas circulation around the planet as the main culprit of the temperature difference on WASP-39 b. On a highly irradiated exoplanet like WASP-39 b that orbits relatively close to its star, researchers generally expect the gas to be moving as the planet rotates around its star: Hotter gas from the dayside should move through the evening to the nightside via a powerful equatorial jet stream. Since the temperature difference is so extreme, the air pressure difference would also be significant, which in turn would cause high wind speeds. Image C: Transit Light Curve Using General Circulation Models, 3-dimensional models similar to the ones used to predict weather patterns on Earth, researchers found that on WASP-39 b the prevailing winds are likely moving from the night side across the morning terminator, around the dayside, across the evening terminator and then around the nightside. As a result, the morning side of the terminator is cooler than the evening side. In other words, the morning side gets slammed with winds of air that have been cooled on the nightside, while the evening is hit by winds of air heated on the dayside. Research suggests the wind speeds on WASP-39 b can reach thousands of miles an hour! “This analysis is also particularly interesting because you’re getting 3D information on the planet that you weren’t getting before,” added Espinoza. “Because we can tell that the evening edge is hotter, that means it’s a little puffier. So, theoretically, there is a small swell at the terminator approaching the nightside of the planet.” The team’s results have been published in Nature. The researchers will now look to use the same method of analysis to study atmospheric differences of other tidally locked hot Jupiters, as part of Webb Cycle 2 General Observers Program 3969. WASP-39 b was among the first targets analyzed by Webb as it began regular science operations in 2022. The data in this study was collected under Early Release Science program 1366, designed to help scientists quickly learn how to use the telescope’s instruments and realize its full science potential. 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).

Buzzing with bees, baby birds, and wildflowers, the rooftop garden atop building 12 at Johnson Space Center in Houston reflects NASA’s commitment to environmental stewardship. Originally constructed in 1963, the facility was transformed in 2012, incorporating energy-efficient features that earned it LEED Gold certification. The certification is a globally recognized symbol of sustainability achievement and leadership. Today, the building serves as a testament to NASA’s commitment to ecological innovation. Nestled between the Mission Control Center and building 16, this hidden gem is part of a series of pioneering efforts at Johnson to demonstrate how even the most unexpected locations can become vibrant ecosystems. Aerial views of Johnson Space Center’s rooftop garden. NASA/Bill Stafford Initiated by Joel Walker, director of Center Operations, and designed alongside NASA engineers, the rooftop garden exemplifies green architecture with integrated solar panels, an underfloor air distribution system, and wind turbines. “It was something of an experiment to see what worked well and what we might use in future projects,” said Walker. Native Texas Bluebonnet atop building 12 at NASA’s Johnson Space Center in Houston. The Center Operations team leads sustainability efforts at Johnson, working across multiple directorates and teams. Together, they manage Johnson’s 1,600 acres, which host a diverse array of plants and wildlife. Building 12’s green roof provides benefits such as reduced potable water and energy usage, better stormwater management, protection from UV rays, and increased stability in high winds. This unique space provides an ideal environment for nesting birds and visiting pollinators and boasts a projected lifespan of 50 years, significantly longer than the 20 to 25 years typical of a conventional roof. “I was genuinely surprised by the variety of native species thriving in our rooftop garden,” said Johnson’s wildlife biologist Strausser. “We’ve observed far more species than we ever anticipated, which is both fascinating and encouraging for our conservation efforts.” Johnson team members meet on the building 12 rooftop to assess and monitor the plants. Initially, the project started with non-native ornamental plants that ******* in the harsh Houston climate. Replanting the garden yielded mixed results until the team hand-scattered a blend of native grass seed and wildflowers. This method proved to be a successful, at a fraction of the cost estimated for professional planting. “Sometimes the easiest way is the best!” said Walker. “It looks great now and is much more durable too.” View the full article

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This image shows an aviation version of a smartphone navigation app that makes suggestions for an aircraft to fly an alternate, more efficient route. The new trajectories are based on information available from NASA’s Digital Information Platform and processed by the Collaborative Departure Digital Rerouting tool.NASA Just like your smartphone navigation app can instantly analyze information from many sources to suggest the best route to follow, a NASA-developed resource is now making data available to help the aviation industry do the same thing. To assist air traffic managers in keeping airplanes moving efficiently through the skies, information about weather, potential delays, and more is being gathered and processed to support decision making tools for a variety of aviation applications. Appropriately named the Digital Information Platform (DIP), this living database hosts key data gathered by flight participants such as airlines or drone operators. It will help power additional tools that, among other benefits, can save you travel time. Ultimately, the aviation industry… and even the flying public, will benefit from what we develop. Swati Saxena NASA Aerospace Engineer “Through DIP we’re also demonstrating how to deliver digital services for aviation users via a modern cloud-based, service-oriented architecture,” said Swati Saxena, DIP project manager at NASA’s Ames Research Center in California. The intent is not to compete with others. Instead, the hope is that industry will see DIP as a reference they can use in developing and implementing their own platforms and digital services. “Ultimately, the aviation industry – the Federal Aviation Administration, commercial airlines, flight operators, and even the flying public – will benefit from what we develop,” Saxena said. The platform and digital services have even more benefits than just saving some time on a journey. For example, NASA recently collaborated with airlines to demonstrate a traffic management tool that improved traffic flow at select airports, saving thousands of pounds of jet fuel and significantly reducing carbon emissions. Now, much of the data gathered in collaboration with airlines and integrated on the platform is publicly available. Users who qualify can create a guest account and access DIP data at a new website created by the project. It’s all part of NASA’s vision for 21st century aviation involving revolutionary next-generation future airspace and safety tools. Managing Future Air Traffic During the 2030s and beyond, the skies above the ******* States are expected to become much busier. Facing this rising demand, the current National Airspace System – the network of U.S. aviation infrastructure including airports, air navigation facilities, and communications – will be challenged to keep up. DIP represents a key piece of solving that challenge. NASA’s vision for future airspace and safety involves new technology to create a highly automated, safe, and scalable environment. What this vision looks like is a flight environment where many types of vehicles and their pilots, as well as air traffic managers, use state-of-the-art automated tools and systems that provide highly detailed and curated information. These tools leverage new capabilities like machine learning and artificial intelligence to streamline efficiency and handle the increase in traffic expected in the coming decades. Digital Services Ecosystem in Action To begin implementing this new vision, our aeronautical innovators are evaluating their platform, DIP, and services at several airports in Texas. This initial stage is a building block for larger such demonstrations in the future. “These digital services are being used in the live operational environment by our airline partners to improve efficiency of the current airspace operations,” Saxena said. “The tools are currently in use in the Dallas/Fort Worth area and will be deployed in the Houston airspace in 2025.” The results from these digital tools are already making a difference. Proven Air Traffic Results During 2022, a NASA machine learning-based tool named Collaborative Digital Departure Rerouting, designed to improve the flow of air traffic and prevent flight delays, saved more than 24,000 lbs. (10,886 kg.) of fuel by streamlining air traffic in the Dallas area. If such tools were used across the entire country, the improvements made in efficiency, safety, and sustainability would make a notable difference to the flying public and industry. “Continued agreements with airlines and the aviation industry led to the creation and expansion of this partnership ecosystem,” Saxena said. “There have been benefits across the board.” DIP was developed under NASA’s Airspace Operations and Safety Program. Learn about NASA’s Collaborative Digital Departure Rerouting tool and how it uses information from the Digital Information Platform to provide airlines with routing options similar to how drivers navigate using cellphone apps.

This image was taken by the Front Hazard Avoidance Camera (Front Hazcam) aboard NASA’s Mars rover Curiosity on Sol 4237 – Martian day 4,237 of the Mars Science Laboratory mission – on July 7, 2024 at 14:46:38 UTC. Earth planning date: Wednesday, July 10, 2024 Curiosity is currently trekking across Gediz Vallis channel because, as my nephew’s favorite book says, if we can’t go around it… we’ve got to go through it! Recently we’ve been parked for a while on the channel to drill “Mammoth Lakes,” ([Hidden Content]) and are now on the move once again exploring the rubbly rocks. Today the science team planned two sols of activity for Curiosity as we venture on through and across Gediz Vallis channel. On the first sol we undertake nearly two hours of planned science. This includes Navcam deck monitoring and a Mastcam tau, to measure dust in the atmosphere as part of our atmospheric and environmental activities, alongside some geology-focused observations. MAHLI is taking a close up image of “Donohue Pass” that we targeted with ChemCam LIBS and Mastcam imagery in the previous plan ([Hidden Content]). ChemCam will take a LIBS on a rock named “Negit Island” that caught the team’s eye with a lighter base and a darker upper section. ChemCam will also take two RMIs of Gediz Vallis, one to document the wall of Gediz Vallis channel that we can see up ahead of us, and one looking at the rocks that sit within the channel. Mastcam is also taking a look at the wall of Gediz Vallis, as well as continuing a mega-mosaic started in the last plan that took 54 images of “Stubblefield Canyon.” Today we planned another 48 images to document the rest of this area named “Echo Ridge.” ChemCam will take a passive observation of an interesting rubbly target in this region called “Wishbone Lake,” prior to a five-meter drive (about 16 feet) over to this feature. Once we have arrived, Curiosity will take some post-drive Navcam imaging and a MARDI image of our left-front wheel. After a well-deserved sleep, on the second sol of this plan Curiosity will automatically choose a LIBS target in our new workspace, before taking a dust-****** and suprahorizon movie to round off this plan.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Paul Dumbacher, right, lead test engineer for the Propulsion Test Branch at NASA’s Marshall Space Flight Center in Huntsville, Alabama, confers with Meredith Patterson, solid propulsion systems engineer, as they install the 11-inch hybrid rocket motor testbed into its cradle in Marshall’s East Test Stand. The new testbed, offering versatile, low-cost test opportunities to NASA propulsion engineers and their government, academic, and industry partners, reflects the collaboration of dozens of team members across multiple departments at Marshall. NASA/Charles Beason In June, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, unveiled an innovative, 11-inch hybrid rocket motor testbed. The new hybrid testbed, which features variable flow capability and a 20-second continuous ***** duration, is designed to provide a low-cost, quick-turnaround solution for conducting hot-***** tests of advanced nozzles and other rocket engine hardware, composite materials, and propellants. Solid rocket propulsion ******** a competitive, reliable technology for various compact and heavy-lift rockets as well as in-space missions, offering low propulsion element mass, high energy density, resilience in extreme environments, and reliable performance. “It’s time consuming and costly to put a new solid rocket motor through its paces – identifying how materials perform in extreme temperatures and under severe structural and dynamic loads,” said Benjamin Davis, branch chief of the Solid Propulsion and Pyrotechnic Devices Branch of Marshall’s Engineering Directorate. “In today’s fast-paced, competitive environment, we wanted to find a way to condense that schedule. The hybrid testbed offers an exciting, low-cost solution.” Initiated in 2020, the project stemmed from NASA’s work to develop new composite materials, additively manufactured – or 3D-printed – nozzles, and other components with proven benefits across the spacefaring spectrum, from rockets to planetary landers. After analyzing future industry requirements, and with feedback from NASA’s aerospace partners, the Marshall team recognized that their existing 24-inch rocket motor testbed – a subscale version of the Space Launch System booster – could prove too costly for small startups. Additionally, conventional, six-inch test motors limited flexible configuration and required multiple tests to achieve all customer goals. The team realized what industry needed most was an efficient, versatile third option. “The 11-inch hybrid motor testbed offers the instrumentation, configurability, and cost-efficiency our government, industry, and academic partners need,” said Chloe Bower, subscale solid rocket motor manufacturing lead at Marshall. “It can accomplish multiple test objectives simultaneously – including different nozzle configurations, new instrumentation or internal insulation, and various propellants or flight environments.” “That quicker pace can reduce test time from months to weeks or days,” said Precious Mitchell, solid propulsion design lead for the project. Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, assess components of the 11-inch hybrid rocket motor testbed in the wake of successful testing in June. Among Marshall personnel leading in-house development of the new testbed are, from left, Chloe Bower, subscale solid rocket motor manufacturing lead; Jacobs manufacturing engineer Shelby Westrich; and Precious Mitchell, solid propulsion design lead. NASA/Benjamin Davis Another feature of great interest is the on/off switch. “That’s one of the big advantages to a hybrid testbed,” Mitchell continued. “With a solid propulsion system, once it’s ignited, it will ***** until the fuel is spent. But because there’s no oxidizer in hybrid fuel, we can simply turn it off at any point if we see anomalies or need to fine-tune a test element, yielding more accurate test results that precisely meet customer needs.” The team expects to deliver to NASA leadership final test data later this summer. For now, Davis congratulates the Marshall propulsion designers, analysts, chemists, materials engineers, safety personnel, and test engineers who collaborated on the new testbed. “We’re not just supporting the aerospace industry in broad terms,” he said. “We’re also giving young NASA engineers a chance to get their hands ****** in a practical test environment solving problems. This work helps educate new generations who will carry on NASA’s mission in the decades to come.” For nearly 65 years, Marshall teams have led development of the U.S. space program’s most powerful rocket engines and spacecraft, from the Apollo-era Saturn V rocket and the space shuttle to today’s cutting-edge propulsion systems, including NASA’s newest rocket, the Space Launch System. NASA technology testbeds designed and built by Marshall engineers and their partners have shaped the reliable technologies of spaceflight and continue to enable discovery, testing, and certification of advanced rocket engine materials and manufacturing techniques.

6 Min Read Vivid Portrait of Interacting Galaxies Marks Webb’s Second Anniversary Webb’s view of the interacting galaxies of Arp 142 that combines Webb’s NIRCam and MIRI instrument images. Full image below. Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA’s James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a “parade” of discoveries by astronomers around the world. “Since President Biden and Vice President Harris unveiled the first image from the James Webb Space Telescope two years ago, Webb has continued to unlock the mysteries of the universe,” said NASA Administrator Bill Nelson. “With remarkable images from the corners of the cosmos, going back nearly to the beginning of time, Webb’s capabilities are shedding new light on our celestial surroundings and inspiring future generations of scientists, astronomers, and explorers.” “In just two years, Webb has transformed our view of the universe, enabling the kind of world-class science that drove NASA to make this mission a reality,” said Mark Clampin, director of the Astrophysics Division at NASA Headquarters in Washington. “Webb is providing insights into longstanding mysteries about the early universe and ushering in a new era of studying distant worlds, while returning images that inspire people around the world and posing exciting new questions to answer. It has never been more possible to explore every facet of the universe.” The telescope’s specialization in capturing infrared light — which is beyond what our own eyes can detect — shows these galaxies, collectively known as Arp 142, locked in a slow cosmic dance. Webb’s observations, which combine near- and mid-infrared light from Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument), respectively, clearly show that they are joined by a haze represented in blue that is a mix of stars and gas, a result of their mingling. Their ongoing interaction was set in motion between 25 and 75 million years ago, when the Penguin (individually cataloged as NGC 2936) and the Egg (NGC 2937) completed their first pass. They will go on to shimmy and sway, completing several additional loops before merging into a single galaxy hundreds of millions of years from now. Image A: Interacting Galaxies Arp 142 (NIRCam and MIRI) The distorted spiral galaxy at center, the Penguin, and the compact elliptical at left, the Egg, are locked in an active embrace. This near- and mid-infrared image combines data from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument), and marks the telescope’s second year of science. Webb’s view shows that their interaction is marked by a glow of scattered stars represented in blue. Known jointly as Arp 142, the galaxies made their first pass by one another between 25 and 75 million years ago, causing “fireworks,” or new star formation, in the Penguin. The galaxies are approximately the same mass, which is why one hasn’t consumed the other. Let’s Dance! Before their first approach, the Penguin held the shape of a spiral. Today, its galactic center gleams like an eye, its unwound arms now shaping a beak, head, backbone, and fanned-out tail. Like all spiral galaxies, the Penguin is still very rich in gas and dust. The galaxies’ “dance” gravitationally pulled on the Penguin’s thinner areas of gas and dust, causing them to ****** in waves and form stars. Look for those areas in two places: what looks like a fish in its “beak” and the “feathers” in its “tail.” Surrounding these newer stars is smoke-like material that includes carbon-containing molecules, known as polycyclic aromatic hydrocarbons, which Webb is exceptional at detecting. Dust, seen as fainter, deeper orange arcs also swoops from its beak to tail feathers. In contrast, the Egg’s compact shape ******** largely unchanged. As an elliptical galaxy, it is filled with aging stars, and has a lot less gas and dust that can be pulled away to form new stars. If both were spiral galaxies, each would end the first “twist” with new star formation and twirling curls, known as tidal tails. Another reason for the Egg’s undisturbed appearance: These galaxies have approximately the same mass or heft, which is why the smaller-looking elliptical wasn’t consumed or distorted by the Penguin. It is estimated that the Penguin and the Egg are about 100,000 light-years apart — quite close in astronomical terms. For context, the Milky Way galaxy and our nearest neighbor, the Andromeda Galaxy, are about 2.5 million light-years apart. They too will interact, but not for about 4 billion years. Now, look to the top right to spot a galaxy that is not at this party. This edge-on galaxy, cataloged PGC 1237172, is 100 million light-years closer to Earth. It’s also quite young, teeming with new, blue stars. Want one more party trick? Switch to Webb’s mid-infrared-only image to see PGC 1237172 practically disappear. Mid-infrared light largely captures cooler, older stars and an incredible amount of dust. Since the galaxy’s stellar population is so young, it “vanishes” in mid-infrared light. Image B: Interacting Galaxies Arp 142 (MIRI Only) NASA’s James Webb Space Telescope’s mid-infrared view of interacting galaxies Arp 142 seems to sing in primary colors. The Egg shows up as a tiny, teal-******** oval, because it is made up of old stars and has lost or used up most of its gas and dust. At right, the Penguin’s star-forming regions are represented in pink and purple, and contain smoke-like material known as polycyclic aromatic hydrocarbons. Also take a moment to scan the background. Webb’s image is overflowing with distant galaxies. Some take spiral and oval shapes, like those threaded throughout the Penguin’s “tail feathers,” while others scattered throughout are shapeless dots. This is a testament to the sensitivity and resolution of the telescope’s infrared instruments. (Compare Webb’s view to the 2018 observation that combines infrared light from NASA’s retired Spitzer Space Telescope and near-infrared and visible light from NASA’s Hubble Space Telescope.) Even though these observations only took a few hours, Webb revealed far more distant, redder, and dustier galaxies than previous telescopes – one more reason to expect Webb to continue to expand our understanding of everything in the universe. Want more? Take a tour to the image, “fly through” it in a visualization, and compare Webb’s image to the Hubble Space Telescope’s.

3 min read Hubble Measures the Distance to a Supernova This NASA/ESA Hubble Space Telescope image features the galaxy NGC 3810. ESA/Hubble & NASA, D. Sand, R. J. Foley Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. Beyond that, astronomers need to use various indirect methods; one of the most important examines Type Ia supernovae, and this is where the NASA/ESA Hubble Space Telescope excels. NGC 3810, the galaxy featured in this image, was the host of a Type Ia supernova in 2022. In early 2023, Hubble focused on this and a number of other galaxies to closely examine recent Type Ia supernovae. Type Ia supernovae are the result of a white dwarf exploding, and their peak brightness is very consistent. This attribute allows astronomers to use Type Ia supernovae to measure distances: we know how bright a Type Ia supernova should be, so we can tell how far away it must be by how dim it appears. One snag with this method is intergalactic dust. Because intergalactic dust blocks some of the supernova’s light, astronomers need to determine how much light the dust reduces to accurately measure the supernova’s brightness and calculate its distance. Hubble’s unique capabilities offer them a clever way of doing this. Astronomers use Hubble to take images of the same Type Ia supernovae in ultraviolet light, which the dust almost completely blocks out, and in infrared light, which passes through dust nearly unaffected. By carefully noting how much light comes through at each wavelength, astronomers can determine how much dust ***** between Hubble and the supernova, letting them confidently calibrate the relationship between a supernova’s brightness and its distance. Hubble’s unique capability to observe in ultraviolet and infrared wavelengths of light in great detail with the same instrument makes it the perfect tool for these types of observations. Indeed, some of the data used to make this beautiful image of NGC 3810 focused on its 2022 supernova. You can see it as a point of light just below the galactic nucleus in the annotated image below. This annotated Hubble image of NGC 3810 denotes the location of the Type Ia supernovae SN 2022zut, It was the eighteen thousand, one hundred and forty-second supernova found in 2022! ESA/Hubble & NASA, D. Sand, R. J. Foley There are many ways to measure cosmic distances, but Type Ia supernovae are one of the most useful and accurate tools because they are so bright. Astronomers must use other methods as well, either as an independent check against other distance measurements, or to measure at much closer or farther distances. One such method, that also works for galaxies, is comparing their rotation speed to their brightness; based on that method, NGC 3810 is about 50 million light-years from Earth.

Portrait of retired NASA astronaut Joe Engle wearing flight suit in front of an X-15 fighter circa 1963. Retired NASA astronaut and U.S. Air Force Maj. Gen. Joe Engle ***** July 10, surrounded by his family at home in Houston. Among his many honors, he is the only astronaut to pilot both the X-15 and space shuttle. He was 91. Engle became an astronaut at age 32 while flying the X-15 for the U.S. Air Force, becoming the youngest pilot ever to qualify as an astronaut. When selected as a NASA astronaut candidate in 1966, he was the only person selected that was already engaged in spaceflight operations. He was the last surviving X-15 pilot. “A natural pilot, Gen. Joe Engle helped humanity’s dreams take flight – in the X-15 program, the Apollo Program, and as one of the first commanders in the Space Shuttle Program,” said NASA Administrator Bill Nelson. “He was one of the first astronauts I met at NASA’s Johnson Space Center in Houston. I’ll never forget his big smile, his warmth, and his courage. We all will miss him.” Engle was born in Dickinson County, Kansas, and attended the University of Kansas, Lawrence, where he graduated with a degree in Aeronautical Engineering in 1955. He received his commission through the Air Force Reserve Officers Training Course, earning his pilot wings in 1958. As a NASA astronaut, he supported the Apollo Program, and was backup lunar module pilot for Apollo 14. In 1977, he served as commander of the space shuttle Enterprise, which used a modified Boeing 747 shuttle carrier aircraft to release Enterprise for approach and landing tests. In November 1981, he commanded the second flight of the space shuttle Columbia. He was the first and only pilot to manually fly an aerospace vehicle from Mach 25 to landing. He accumulated the last of his 224 hours in space when he commanded the space shuttle Discovery in August 1985, one of the most challenging shuttle missions ever. On that mission the crew deployed three commercial satellites and retrieved, repaired, and redeployed another malfunctioning satellite that had been launched on a previous shuttle mission. “As we mourn the immense loss of Joe, we’re thankful for his notable contributions to the advancement of human spaceflight,” said Vanessa Wyche, center director, NASA Johnson. “Joe’s accomplishments and legacy of perseverance will continue to inspire and impact generations of explorers for years to come.” Engle flew more than 180 different aircraft types and logged more than 14,000 flight hours. His military decorations include the Department of Defense Distinguished Service Medal, U.S. Air Force Distinguished Service Medal, and the Air Force Distinguished Flying Cross with Oak Leaf Cluster. He has received the NASA Distinguished Service Medal and Space Flight Medal, as well as the Harmon International Aviation Trophy, the Collier Trophy, the Goddard Space Trophy, the Gen. Thomas D. White Space Trophy, and the Kinchelow Experimental Test Pilot’s Trophy. In 1992, he was inducted into the Aerospace Walk of Honor. “Joe Henry was a loving husband, father, and grandfather.

A few days before they left Skylab on Feb. 8, 1974, the final crew to occupy the station raised its altitude, hoping to keep it in orbit until a future space shuttle could revisit it. But higher than predicted solar activity caused the Earth’s atmosphere to expand, increasing drag on the large vehicle, causing its orbit to decay faster than expected. In 1978, controllers reactivated the station and changed its attitude, hoping to keep it in orbit as long as possible by reducing atmospheric drag. In the meantime, delays in the space shuttle’s development eventually made it impossible for a shuttle to revisit Skylab before it reentered the Earth’s atmosphere. On July 11, 1979, Skylab reentered, with debris landing over the Indian Ocean and Australia. Lessons learned from deorbiting large spacecraft like Skylab and others will inform the eventual deorbiting of the International Space Station.

Right: A more whimsical depiction of the Skylab reboost by the space shuttle, as drawn by a cartoonist at NASA’s Johnson Space Center in Houston. When the Skylab 4 astronauts departed the station on Feb. 8, 1974, they left it in a 269-by-283-mile orbit. Just one day after the crew left the station, operators in the Mission Control Center at NASA’s Johnson Space Center in Houston ran a few final systems checks, oriented Skylab in a gravity-gradient attitude – meaning the heavier workshop faced the Earth – vented its atmosphere, and turned off its power. In this attitude, and based on predictions of the Sun’s activity in the upcoming solar cycle that would increase atmospheric drag and reduce Skylab’s altitude, scientists estimated that the station would remain in orbit until March 1983. However, the solar cycle intensified into the second most active one in a century and atmospheric perturbations shifted Skylab out of the gravity-gradient attitude, increasing its drag. By 1977, revised estimates projected Skylab’s reentry occurring as early as mid-1979. Although the space shuttle had yet to fly, NASA devised a plan for astronauts on one of its early missions to attach a rocket stage to Skylab and use it to either boost the station into a higher storage orbit or deorbit it in a controlled fashion into the Pacific Ocean. At 169,000 pounds, Skylab represented the heaviest spacecraft to reenter up to that time, and engineers believed that some of its components would survive the entry. Keeping the debris away from populated areas remained a priority. Left: Plot of Skylab’s altitude from launch until reentry. Right: Illustration of the five ground stations used during the reactivation and tracking of Skylab. To ensure that Skylab stayed aloft long enough for this shuttle mission to reach it, NASA needed to reactivate it. Because Skylab had no ability to reboost itself, its rate of decay could only be slightly controlled by changing the station’s attitude. Between March and June 1978, using the limited communications afforded by five ground stations, a small team of controllers methodically reactivated Skylab after a more than four-year passive *******. Remarkably, the station’s systems, including its all-important batteries, had survived the intervening ******* in good condition. When controllers fully reactivated Skylab on June 11, 1978, its altitude had decreased to 250 miles, and to prolong its life NASA decided to keep the station activated to control its attitude. Using its Thruster Attitude Control System, operators commanded Skylab into an End On Velocity Vector (EOVV) minimum drag attitude, with its forward end pointing in the direction of flight. Skylab remained in the EOVV attitude until Jan. 25, 1979, and engineers estimated that this extended the station’s orbital life by 3.5 months. By late 1978, with slips in the shuttle schedule, saving Skylab seemed no longer feasible. In a Dec. 19, 1978, press conference, NASA’s Associate Administrator for Space Transportation Systems John F. Yardley announced the cancellation of the shuttle reboost mission and the end of efforts to control Skylab’s attitude. Yardley emphasized the low likelihood of an uncontrolled Skylab reentry resulting in debris hitting populated areas, citing the example of the spent second stage of the Saturn V rocket that launched Skylab. That empty stage, larger in size although at 83,000 pounds less massive than Skylab, reentered out of control on Jan. 11, 1975, falling harmlessly into the Atlantic Ocean, about 1,000 miles west of Gibraltar.

Right: Ground track of Skylab’s final orbit and the debris footprint in the Indian Ocean and Australia. On Jan. 25, 1979, controllers maneuvered Skylab from EOVV to solar inertial attitude, the orientation it maintained during its operational life, to ensure its solar arrays remained pointed at the Sun to keep the station’s batteries charged. Studies indicated that as Skylab descended below 161 miles, aerodynamic torques would make it difficult to maintain the solar inertial attitude. On June 20, with Skylab at 163 miles, controllers commanded it into a high-drag Torque Equilibrium Attitude (TEA). This gave controllers the ability to select the best orbit to ******** the final reentry, one that overflew mostly water to minimize any potential harm to people and property. Orbit 34,981 on July 11 met those criteria. On that orbit, after Skylab passed over North America, it flew southeast over the Atlantic Ocean, round the southern tip of *******, then northeast across the Indian Ocean before passing over the next major landmass, mainly sparsely populated areas of Australia. On the planned day of reentry, controllers commanded Skylab into a slow tumble at an altitude of 93 miles to better aim the entry point to the east of the southern tip of *******, causing the breakup over the Indian Ocean. After this point, the ground no longer controlled the station. With a debris footprint possibly 3,500 miles long, some debris landing in Australia remained a possibility.

Tracking at the Bermuda station indicated Skylab’s large solar array still attached to the workshop. Controllers at Ascension Island in the South Atlantic made contact with Skylab as it flew 66 miles overhead, its large solar array beginning to detach from the workshop, itself already heating from the reentry. Once the disintegrating station passed out of range of Ascension, it continued its reentry unmonitored. Skylab finally broke apart at an altitude of 10 miles, slightly lower than expected, moving the impact footprint further east than planned. Pieces of Skylab falling on Western Australia created sonic booms heard by the inhabitants of the few towns in the Outback. The actual documented debris footprint stretched 2,450 miles. A museum in Esperance houses some of the recovered debris. Skylab Flight Director Charles S. Harlan said in a news conference after the event, “The surprise is over. No more suspense. Skylab is on the planet Earth.” Left: The Salyut 7-Kosmos 1686 complex photographed by the last departing crew. Middle: Reentry trajectory of the Salyut 7-Kosmos 1686 complex.

In contrast to the partially controlled Skylab entry, the Salyut 7-Kosmos 1686 complex made an uncontrolled reentry over Argentina on Feb. 7, 1991. At 88,491 pounds, the complex had about half the mass of Skylab. Although controllers had sent all previous Salyut stations on controlled reentries into the Pacific Ocean, they lost communications with Salyut 7 more than two years before its reentry. A crew last occupied the Salyut 7-Kosmos 1686 complex in June 1986. In August 1986, engines on the Kosmos 1686 module raised the complex’s orbit by 84 miles to 295 miles, with an anticipated reentry in 1994. Like Skylab, controllers considered a possible retrieval of Salyut 7 by a Buran space shuttle before that program’s cancellation. The last communications with Salyut 7 occurred in December 1989. Again, like Skylab, higher than anticipated solar activity in the late 1980s accelerated its descent. The station initially entered a gravity gradient attitude with the heavier Kosmos 1686 facing the Earth, but that attitude degraded significantly as the station encountered denser atmosphere in January 1991. And although said to be uncontrollable, apparently on Feb. 5, ground teams commanded it into a head on attitude to reduce drag and direct entry to an orbit that overflew less populated areas. Fuel depletion did not allow completion of the maneuver and atmospheric drag torqued the vehicle away from this attitude. Although planned for reentry over the south Pacific Ocean, Salyut 7 overshot the target and came down over Argentina, with a few fragments recovered. Left: The Mir complex in 1998. Middle: The March 2001 reentry of Mir photographed from Fiji. Right: The reentry trajectory of Mir in March 2001. Lessons learned from the earlier reentries of large space stations led controllers to devise a three-stage process to deorbit the Mir space station in a controlled fashion into the Pacific Ocean in March 2001. In the first stage, controllers allowed orbital drag to bring the 285,940-pound station, at the time the heaviest object to reenter, down to an average altitude of 140 miles. For the second stage, on March 23, the docked Progress M1-5 fired its engines twice to lower Mir’s orbit to 103 by 137 miles. Two orbits later, the Progress fired its engines for 22 minutes to bring Mir out of orbit. It burned up on reentry over the South Pacific Ocean, with observers in Nadi, Fiji, watching its final moments. The International Space Station, the largest spacecraft in orbit. In anticipation of the eventual controlled disposal of the International Space Station, on June 26, 2024, NASA selected SpaceX to develop and deliver the U.S. Deorbit Vehicle. The vehicle will safely deorbit the space station, the largest and, at over 900,000 pounds, by far the heaviest spacecraft in orbit, after the end of its operational life, currently expected in 2030. Past experiences can provide useful lessons learned.

“We have a group photo of my first project here, ASTRO-H, and that one means a lot to me because I came [to that NASA project] fresh off the street. I was super scared and intimidated. It was me and three other [technicians], who were also all new, and a handful of very seasoned scientists and engineers. And we came together. “And we actually came in — I believe — under budget, ahead of schedule, and exceeded all expectations for our test results. That’s kind of unheard of, you know what I mean? We had such a good environment in the lab. Everybody got along so well. It was all teamwork. And everything just gelled. “So when I look back on that photo from 14 years ago, first of all, I look really young in it. And secondly, it makes me realize how blessed and lucky I’ve been to be here for so long. It reminds me of that guy who was really nervous and still did alright. [It reminds me] to have a little confidence in myself, just be me, and do the work. It’ll all work out. “I love looking back at that first team photo and just remembering how raw everything was at the time and how well it still came out.” —Clifton Brown, Engineering Technician, OMES III, NASA’s Goddard Space Flight Center Image Credit: NASA/Thalia Patrinos Interviewer: NASA/Thalia Patrinos Check out some of our other Faces of NASA.

NASA/Eric Bordelon Team members are installing pedestals aboard NASA’s Pegasus barge to hold and secure the massive core stage of NASA’s SLS (Space Launch System) rocket, indicating NASA barge crews are nearly ready for its first delivery to support the Artemis II test flight around the Moon. The barge will ferry the core stage on a 900-mile journey from the agency’s Michoud Assembly Facility in New Orleans to its Kennedy Space Center in Florida. The Pegasus crew began installing the pedestals July 10.The barge, which previously was used to ferry space shuttle external tanks, was modified and refurbished to compensate for the much larger and heavier core stage for the SLS rocket. Measuring 212 feet in length and 27.6 feet in diameter, the core stage is the largest rocket stage NASA has ever built and the longest item ever shipped by a NASA barge. Pegasus now measures 310 feet in length and 50 feet in width, with three 200-kilowatt generators on board for power. Tugboats and towing vessels will move the barge and core stage from Michoud to Kennedy, where the core stage will be integrated with other elements of the rocket and prepared for launch. Pegasus is maintained at NASA Michoud. NASA is working to land the first woman, first person of ******, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. View the full article
