ESA/Hubble & NASA, C. Murray This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa. Despite being only 10–20% as massive as the Milky Way galaxy, the Large Magellanic Cloud contains some of the most impressive nearby star-forming regions. The scene pictured here is on the outskirts of the Tarantula Nebula, the largest and most productive star-forming region in the local universe. At its center, the Tarantula Nebula hosts the most massive stars known, weighing roughly 200 times the mass of the Sun. The section of the nebula shown here features serene blue gas, brownish-orange dust patches, and a sprinkling of multicolored stars. The stars within and behind the dust clouds appear redder than those that are unobscured by dust. Dust absorbs and scatters blue light more than red light, allowing more of the red light to reach our telescopes, which makes the stars appear redder than they are. This image incorporates ultraviolet and infrared light as well as visible light. Using Hubble observations of dusty nebulae in the Large Magellanic Cloud and other galaxies, researchers can study these distant dust grains, helping them better understand the role that cosmic dust plays in the formation of new stars and planets.

4 Min Read NASA Space Tech’s Favorite Place to Travel in 2025: The Moon! The first image from space of Firefly's Blue Ghost mission 1 lunar lander as it begins its 45-day transit ******* to the Moon. Credits: Firefly Aerospace NASA Space Technology has big travel plans for 2025, starting with a trip to the near side of the Moon! Among ten groundbreaking NASA science and technology demonstrations, two technologies are on a ride to survey lunar regolith – also known as “Moon dust” – to better understand surface interactions with incoming lander spacecraft and payloads conducting experiments on the surface. These dust demonstrations and the data they’re designed to collect will help support future lunar missions. Blue Ghost Mission 1 launched at 1:11 a.m. EST aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The company is targeting a lunar landing on Sunday, March 2. The first image from space of Firefly’s Blue Ghost mission 1 lunar lander as it begins its 45-day transit ******* to the Moon. Firefly Aerospace NASA Space Technology on Blue Ghost Mission 1 NASA’s Electrodynamic Dust Shield (EDS) will lift, transport, and remove particles using electric fields to repel and prevent hazardous lunar dust accumulation on surfaces. The agency’s Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) technology will use stereo imaging to capture the impact of rocket plumes on lunar regolith as the lander descends to the Moon’s surface, returning high-resolution images that will help in creating models to predict regolith erosion – an important task as *******, heavier payloads are delivered to the Moon in close proximity to each other. The EDS and SCALPSS technologies will be delivered to the Moon on Firefly’s first Blue Ghost mission, named Ghost Riders in the Sky, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Its landing target is a 300-mile-wide basin located on the Moon’s near side, called Mare Crisium – a large, dark, basaltic plain that filled an ancient asteroid impact. First-of-their-kind experiments will deploy after landing to gather important data in a broad spectrum of areas including geophysical characteristics, global navigation, radiation tolerant computing, and the behavior of lunar regolith. Replicating the Moon’s harsh environment on Earth is a significant challenge because of extreme temperatures, low gravity, radiation, and dusty surface. The CLPS initiative provides unprecedented access to the lunar surface, allowing us to demonstrate technologies in the exact conditions they were designed for. Missions like Blue Ghost Mission 1 are a true game changer for NASA technology advancement and demonstration.” Michael Johansen Flight Demonstrations Lead for NASA’s Game Changing Development program Dust particles scatter during an experiment for the Electrodynamic Dust Shield in a laboratory at NASA’s Kennedy Space Center in Florida.

What was learned from those early missions – and from thousands of experiments conducted on Earth and in space since – is that successful surface missions require the ability to eliminate dust from all kinds of systems. Lunar landings, for example, cause lunar dust to disperse in all directions and collect on everything that lands there with it. This is one of the reasons such technologies are important to understand. The SCALPSS technology will study the dispersion of lunar dust, while EDS will demonstrate a solution to mitigate it. Getting this new data on lunar regolith with be pivotal for our understanding of the lunar surface. We’ve long known that lunar dust is a huge challenge. The Lunar Surface Innovation Initiative has enabled us to initiate lunar dust mitigation efforts across the agency, working with industry and international partners. The lunar science, exploration, and technology communities are eager to have new quantitative data, and to prove laboratory experiments and develop technology solutions.” Kristen John Technical Integration Lead for NASA’s Lunar Surface Innovation Initiative (LSII) To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video [VIDEO] Dust on the lunar surface is a significant hazard for systems and astronauts living and working on the Moon. NASA space technologies are developing solutions to retire hurdles in this capability area. NASA Space Technology Dust mitigation technology has come a long way, but we still have a lot to learn to develop surface systems and infrastructure for more complex missions. LSII is actively engaged in this effort, working with the lunar community across sectors to expand knowledge and design new approaches for future technologies. Working alongside the Lunar Surface Innovation Consortium, LSII has a unique opportunity to take a holistic look at dust’s role in the development of surface infrastructure with other key capability areas including in-situ resource utilization, surface power, and surviving the lunar night. Learning from the the Moon benefits Mars science and exploration Capabilities for minimizing dust interaction are as important for future missions on Mars as it is for missions on the Moon. Like the Moon, Mars is also covered with regolith, also called Martian dust or Martian soil, but the properties are different than lunar regolith, both in shape and mineralogy. The challenges Mars rovers have encountered with Martian regolith have provided great insight into the challenges we will face during lunar surface missions. Learning is interwoven and beneficial to future missions whether hundreds of thousands of miles from Earth, on the Moon, or millions, on Mars. Scientist-astronaut Harrison Schmitt, Apollo 17 lunar module pilot, uses an adjustable sampling scoop to retrieve lunar samples during the second Apollo 17 extravehicular activity (EVA).

Engineers and technicians with NASA’s Exploration Ground Systems Program integrate the right forward center segment onto mobile launcher 1 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, Jan. 22, 2025. The boosters will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis II Moon rocket and provide more than 75 percent of the total SLS (Space Launch System) thrust during liftoff from NASA Kennedy’s Launch Pad 39BNASA/Kim Shiflett Teams with NASA’s Exploration Ground Systems Program continue stacking the SLS (Space Launch System) rocket’s twin solid rocket booster motor segments for the agency’s Artemis II mission, inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. Currently, six of the 10 segments are secured atop mobile launcher 1 with the right forward center segment as the latest addition. Teams will continue integrating the booster stack – the left center center segment adorned with the NASA “worm” insignia is the next segment to be integrated. The right and left forward assemblies were brought to the VAB from the spaceport’s Booster Fabrication Facility on Jan. 14. The forward assemblies are comprised of three parts: the nose cone which serves as the aerodynamic fairing; a forward skirt, which house avionics; and the frustum which houses motors that separates the boosters from the SLS core stage during flight. The remaining booster segments will be transported from the Rotation, Processing, and Surge Facility to the VAB when engineers are ready to integrate them. The forward assemblies will be the last segments integrated to complete the booster configuration, ahead of integration with the core stage. Image Credit: NASA/Kim Shiflett View the full article

Jan. 24, 2025 NASA’s NICER Continues Science Operations Post Repair NASA crew aboard the International Space Station installed patches to the agency’s NICER (Neutron star Interior Composition Explorer) mission during a spacewalk on Jan. 16. NICER, an X-ray telescope perched near the station’s starboard solar array, resumed science operations later the same day. The patches cover areas of NICER’s thermal shields where damage was discovered in May 2023. These thin filters block sunlight while allowing X-rays to pass through. After the discovery, the NICER team restricted their observations during the station’s daytime to avoid overwhelming the mission’s sensitive detectors. Nighttime observations were unaffected, and the team was able to continue collecting data for the science community to make groundbreaking measurements using the instrument’s full capabilities. The repair went according to plan. Data since collected shows the detectors behind the patched areas are performing better than before during station night, and the overall level of sunlight inside NICER during the daytime is reduced substantially. While NICER experiences less interference from sunlight than before, after analyzing initial data, the team has determined the telescope still experiences more interference than expected. The installed patches cover areas of known damage identified using astronomical observations and from photos taken by both external robotic cameras and astronauts inside the space station. Measurements collected since the repair and close-up, high-resolution photos obtained during the spacewalk are providing new information that may point the way toward further daytime data collection. In the meantime, NICER continues operations with its full measurement capabilities during orbit night to enable further trailblazing discoveries in time domain and multimessenger astrophysics. Media contact: Alise Fisher, NASA Headquarters / Claire Andreoli, NASA Goddard June 8, 2023 Sunlight ‘Leak’ Impacting NASA’s NICER Telescope, Science Continues On Tuesday, May 22, NASA’s NICER (Neutron Star Interior Composition Explorer), an X-ray telescope on the International Space Station, developed a “light leak,” in which unwanted sunlight enters the instrument. While analyzing incoming data since then, the team identified an impact to daytime observations. Nighttime observations seem to be unaffected. The team suspects that at least one of the thin thermal shields on NICER’s 56 X-ray Concentrators has been damaged, allowing sunlight to reach its sensitive detectors. To mitigate the effects on measurements, the NICER team has limited daytime observations to objects far away from the Sun’s position in the sky. The team has also updated commands to NICER that automatically lower its sensitivity during the orbital day to reduce the effects from sunlight contamination. The team is evaluating these changes and assessing additional measures to reduce the impact on science observations. To date, more than 300 scientific papers have used NICER observations, and the team is confident that NICER will continue to produce world-class science.

On Jan. 24, 1985, space shuttle Discovery took off from NASA’s Kennedy Space Center (KSC) in Florida on STS-51C, the first space shuttle mission entirely dedicated to the Department of Defense (DOD). As such, many of the details of the flight remain classified. Discovery’s crew of Commander Thomas “T.K.” Mattingly, Pilot Loren Shriver, Mission Specialists Ellison Onizuka and James Buchli, and Payload Specialist Gary Payton deployed a classified satellite that used an Inertial Upper Stage (IUS) to reach its final geostationary orbit. The three-day mission ended with a landing at KSC. Postflight inspection of the Solid Rocket Boosters (SRBs) revealed the most significant erosion of O-ring seals seen in the shuttle program up to that time, attributed to unusually cold weather before and during launch. The STS-51C crew of Pilot Loren Shriver, seated left, and Commander Thomas “T.K.” Mattingly; Payload Specialist Gary Payton, standing left, and Mission Specialists James Buchli and Ellison Onizuka. The STS-51C crew patch. In October 1982, NASA assigned astronauts Mattingly, Shriver, Onizuka, and Buchli as the STS-10 crew for a dedicated DOD flight aboard Challenger then scheduled for September 1983. Payton joined the crew as a payload specialist in the summer of 1983 with Keith Wright assigned as his backup. The failure of the IUS on STS-6 in April 1983 delayed the STS-10 mission, that also used the IUS, until engineers could identify and fix the cause of the problem. By September 1983, NASA had remanifested the crew and the payload on STS-41F with a July 1984 launch, that changed to STS-41E by November 1983. Additional delays in fixing the IUS delayed the mission yet again, by June 1984 redesignated as STS-51C and slated for December 1984 aboard Challenger. STS-51C marked the third spaceflight for Mattingly, selected in 1966 as part of NASA’s fifth group of astronauts. He served on the prime crew for Apollo 13 until exposure to ******* measles forced his last-minute replacement by his backup. He then flew on Apollo 16 and STS-4. For Shriver, Onizuka, and Buchli, all three selected as astronauts in the class of 1978, STS-51C marked their first trip into space. The U.S. Air Force selected Payton and Wright in August 1979 in its first class of Manned Spaceflight Engineers, and STS-51C marked Payton’s first and only space mission. In November 1984, NASA decided to delay STS-51C from December 1984 to January 1985 and swap orbiters from Challenger to Discovery. Postflight inspections following Challenger’s STS-41G mission in October 1984 revealed degradation of the bonding materials holding thermal protection system tiles onto the orbiter, requiring the replacement of 4,000 tiles. The time required to complete the work precluded a December launch. Tests conducted on Discovery prior to its November STS-51A mission revealed the bonding material to be sound. Space shuttle Discovery rolls out to Launch Pad 39A. The STS-51C crew poses during launch pad evacuation drills associated with the Terminal Countdown Demonstration Test. The STS-51C crew exits crew quarters for the ride to Launch Pad 39A. On Jan. 5, 1985, Discovery rolled out from KSC’s Vehicle Assembly Building, where workers mated it with its External Tank (ET) and SRBs, to Launch Pad 39A. There, engineers conducted the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the actual countdown, on Jan. 6-7, with the crew participating in the final few hours much as they would on launch day. The astronauts returned to KSC on Jan. 20 to prepare for the planned launch on Jan. 23. The day before, NASA managers decided to delay the launch by one day due to unseasonably cold weather, with concern about sub-freezing temperatures causing ice to form on the ET and possibly coming loose during ascent and damaging the vehicle. The DOD had requested that NASA keep the actual launch time secret until T minus nine minutes, with most of the countdown taking place hidden from public view. Liftoff of space shuttle Discovery on STS-51C. Liftoff of Discovery on its third mission, STS-51C, came at 2:50 p.m. EST on Jan. 24, beginning the 15th space shuttle flight. Eight and a half minutes later, Discovery and its five-man crew had reached orbit. And, at the DOD customer’s request, all public coverage of the mission ended. Although NASA could not reveal the spacecraft’s orbital parameters, trade publications calculated that Discovery first entered an elliptical orbit, circularized over the next few revolutions, prior to Onizuka deploying the IUS and payload combination on the seventh orbit. Neither NASA nor the DOD have released any imagery of the deployment or even of the payload bay, with only a limited number of in-cabin and Earth observation photographs made public.

New Orleans and the Mississippi River delta. Discovery touches down at NASA’s Kennedy Space Center in Florida. The STS-51C astronauts are greeted by NASA officials as they exit Discovery. To maintain the mission’s secrecy, NASA could reveal the touchdown time only 16 hours prior to the event. On Jan. 27, Mattingly and Shriver brought Discovery to a smooth landing at KSC’s Shuttle Landing Facility after a flight of three days one hour 33 minutes, the shortest space shuttle mission except for the first two orbital test flights. The astronauts orbited the Earth 49 times. About an hour after touchdown, the astronaut crew exited Discovery and boarded the Astrovan for the ride back to crew quarters. Neither NASA management nor the astronauts held a post mission press conference. The U.S. Air Force announced only that the “IUS aboard STS-51C was deployed from the shuttle Discovery and successfully met its mission objectives.” Later in the day, ground crews towed Discovery to the Orbiter Processing Facility to begin preparing it for its next planned mission, STS-51D in March. Postscript Following the recovery of SRBs after each shuttle mission, engineers conducted detailed inspections before clearing them for reuse. After STS-51C, inspections of the critical O-ring seals that prevented hot gases from escaping from the SRB field joints revealed significant erosion and “blow-by” between the primary and secondary O-rings. Both left and right hand SRBs showed this erosion, the most significant of the program up to that time. Importantly, these O-rings experienced weather colder than any previous shuttle mission, with overnight ambient temperatures in the teens and twenties. Even at launch time, the O-rings had reached only 60 degrees. Engineers believed that these cold temperatures made the O-rings brittle and more susceptible to erosion. One year later, space shuttle Challenger launched after similarly cold overnight temperatures, with O-rings at 57 degrees at launch time. The Rogers Commission report laid the blame of the STS-51L accident on the failure of O-rings that allowed super-hot gases to escape from the SRB and impinge on the hydrogen tank in the ET, resulting in the explosion that destroyed the orbiter and claimed the lives of seven astronauts. The commission also faulted NASA’s safety culture for not adequately addressing the issue of O-ring erosion, a phenomenon first observed on STS-2 and to varying degrees on several subsequent missions.

The Expedition 71 crew conducted hundreds of technology demonstrations and science experiments, including the bioprinting of human tissues. These higher-quality tissues printed in microgravity could help advance the production of organs and tissues for transplant and improve 3D printing of foods and medicines on future long-duration space missions. The crew also looked at neurological organoids, created with stem cells from patients to study neuroinflammation, a common feature of neurodegenerative conditions such as Parkinson’s disease. The organoids provided a platform to study these diseases and their treatments and could help address how extended spaceflight affects the brain. As part of Crew-8, Dominick served as commander, Barratt served as pilot, and Epps served as a mission specialist. Dyson launched aboard a Soyuz space as part of an international crew and served as a flight engineer on a six-month research mission. The expedition to the space station was the first spaceflight for Dominick, third for Barratt, first for Epps, and third for Dyson. The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human Learn more about the International Space Station, its research, and its crew, at: [Hidden Content] Joel Wallace Marshall Space Flight Center, Huntsville, Ala. 256-544-0034 *****@*****.tld Share Details Last Updated Jan 24, 2025 EditorBeth RidgewayLocationMarshall Space Flight Center Related TermsMarshall Space Flight Center Explore More 5 min read Exoplanets Need to Be Prepared for Extreme Space Weather, Chandra Finds Article 1 week ago 4 min read NASA Instrument on Firefly’s Blue Ghost Lander to Study Lunar Interior Article 2 weeks ago 3 min read NASA to Test Solution for Radiation-Tolerant Computing in Space Article 2 weeks ago Keep Exploring Discover Related Topics Missions Humans in Space Climate Change Solar System View the full article

NASA JPL is readying for, clockwise from lower right, the launches of CADRE (its engineering models are seen here), Lunar Trailblazer, NISAR (seen in an artist’s concept), Sentinel-6B (artist’s concept), and SPHEREx, as well as the Mars gravity assist of Europa Clipper (artist’s concept).NASA/JPL-Caltech/BAE Systems/Lockheed Martin Space Missions will study everything from water on the Moon to the transformation of our universe after the big bang and ongoing changes to Earth’s surface. With 2024 receding into the distance, NASA’s Jet Propulsion Laboratory is already deep into a busy 2025. Early in the new year, the Eaton Fire came close to JPL, destroying the homes of more than 200 employees, but work has continued apace to maintain mission operations and keep upcoming missions on track. Several missions managed by NASA JPL are prepping for launch this year. Most have been years in the making and launches are, of course, only part of the ******* picture. Other milestones are also on the docket for the federal laboratory, which Caltech manages for NASA. Here’s a glimpse of what lies ahead this year. Mysterious Universe Shaped like the bell of a trumpet and as big as a subcompact car, NASA’s SPHEREx space observatory is aiming for the stars. Known formally as the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, the mission will create four 3D maps of the entire sky in order to improve humanity’s understanding of the universe — how it expanded after the big bang, where ingredients of life can be found in ice grains, and much more. Target launch date: no earlier than Feb. 27 from Vandenberg Space Force Base in California. The Moon’s Icy Secrets NASA’s Lunar Trailblazer aims to help resolve an enduring mystery: Where is the Moon’s water? Scientists have seen signs suggesting it exists even where temperatures soar on the lunar surface, and there’s good reason to believe it can be found as surface ice in permanently shadowed craters, places that have not seen direct sunlight for billions of years. Managed by NASA JPL and led by Caltech, the small satellite will help provide answers, mapping the Moon’s surface water in unprecedented detail to determine the water’s abundance, location, form, and how it changes over time. The small satellite will hitch a ride, slated for late February, on the same launch as the Intuitive Machines-2 delivery to the Moon through NASA’s CLPS (Commercial Lunar Payload Services) initiative. Earth’s Changing Surface A collaboration between the United States and India, NISAR is a major addition to the fleet of satellites studying our changing planet. Short for NASA-Indian Space Research Organisation Synthetic Aperture Radar, the mission’s name is a nesting doll of acronyms, and the spacecraft is a nesting doll of capabilities: The first spacecraft to carry both L-band and S-band radars, it will see surface changes related to volcanoes, earthquakes, ice sheet motion, deforestation, and more in unprecedented detail after it launches in a few months’ time. Sea Level Targeting a November launch, Sentinel-6B will provide global sea surface height measurements — some of the most accurate data of its kind yet — that will improve climate models and hurricane tracking, as well as our understanding of phenomena like El Niño. A collaboration between NASA and ESA (European Space Agency), the spacecraft will take the baton from its twin, Sentinel-6 Michael Freilich, which launched in 2020. Together, the satellites are extending for another 10 years a nearly three-decade record of global sea surface height. Moon Rover Trio As a technology demonstration, the CADRE (Cooperative Autonomous Distributed Robotic Exploration) project marks another step NASA is taking toward developing robots that, by operating autonomously, can boost the efficiency of future missions. The project team at JPL will soon be packing up and shipping CADRE’s three suitcase-size rovers to Texas in preparation for their journey to the Moon aboard a commercial lander through one of NASA’s future CLPS deliveries. The rovers are designed to work together as a team without direct input from mission controllers back on Earth. And, by taking simultaneous measurements from multiple locations, they are meant to show how multirobot missions could enable new science and support astronauts. Quantum Technology Having arrived at the International Space Station in November, SEAQUE (Space Entanglement and Annealing QUantum Experiment) is testing two technologies that, if successful, could enable communication using entangled photons between two quantum systems. The research from this experiment, which gets underway in 2025, could help develop the building blocks for a future global quantum network that would allow equipment such as quantum computers to transfer data securely across large distances. Gravity Assist to Reach Jupiter Launched this past October, Europa Clipper will arrive at Jupiter in 2030 to investigate whether an ocean beneath the ice shell of the gas giant’s moon Europa has conditions suitable for life. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) to reach its destination. Since there are limitations on how much fuel the spacecraft can carry, mission planners are having Europa Clipper fly by Mars on March 1, using the planet’s gravity as a slingshot to add speed to its journey.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Equipped with state-of-the-art technology to test and evaluate communication, navigation, and surveillance systems NASA’s Pilatus PC-12 performs touch-and-go maneuvers over a runway at NASA’s Armstrong Flight Research Center in Edwards, California on Sept. 23, 2024. Researchers will use the data to understand Automatic Dependent Surveillance-Broadcast (ADS-B) signal loss scenarios for air taxi flights in urban areas. To prepare for ADS-B test flights pilots and crew from NASA Armstrong and NASA’s Glenn Research Center in Cleveland, ran a series of familiarization flights. These flights included several approach and landings, with an emphasis on avionics, medium altitude air-work with steep turns, slow flight and stall demonstrations.NASA/Steve Freeman As air taxis, drones, and other innovative aircraft enter U.S. airspace, systems that communicate an aircraft’s location will be critical to ensure air traffic safety. The Federal Aviation Administration (FAA) requires aircraft to communicate their locations to other aircraft and air traffic control in real time using an Automatic Dependent Surveillance-Broadcast (ADS-B) system. NASA is currently evaluating an ADS-B system’s ability to prevent collisions in a simulated urban environment. Using NASA’s Pilatus PC-12 aircraft, researchers are investigating how these systems could handle the demands of air taxis flying at low altitudes through cities. When operating in urban areas, one particular challenge for ADS-B systems is consistent signal coverage. Like losing cell-phone signal, air taxis flying through densely populated areas may have trouble maintaining ADS-B signals due to distance or interference. If that happens, those vehicles become less visible to air traffic control and other aircraft in the area, increasing the likelihood of collisions. NASA pilot Kurt Blankenship maps out flight plans during a pre-flight brief. Pilots, crew, and researchers from NASA’s Armstrong Flight Research Center in Edwards, California and NASA’s Glenn Research Center in Cleveland are briefed on the flight plan to gather Automatic Dependent Surveillance-Broadcast signal data between the aircraft and ping-Stations on the ground at NASA Armstrong. These flights are the first cross-center research activity with the Pilatus-PC-12 at NASA Armstrong.NASA/Steve Freeman To simulate the conditions of an urban flight area and better understand signal loss patterns, NASA researchers established a test zone at NASA’s Armstrong Flight Research Center in Edwards, California, on Sept. 23 and 24, 2024. Flying in the agency’s Pilatus PC-12 in a grid pattern over four ADS-B stations, researchers collected data on signal coverage from multiple ground locations and equipment configurations. Researchers were able to pinpoint where signal dropouts occurred from the strategically placed ground stations in connection to the plane’s altitude and distance from the stations. This data will inform future placement of additional ground stations to enhance signal boosting coverage. “Like all antennas, those used for ADS-B signal reception do not have a constant pattern,” said Brad Snelling, vehicle test team chief engineer for NASA’s Air Mobility Pathfinders project. “There are certain areas where the terrain will block ADS-B signals and depending on the type of antenna and location characteristics, there are also flight elevation angles where reception can cause signal dropouts,” Snelling said. “This would mean we need to place additional ground stations at multiple locations to boost the signal for future test flights. We can use the test results to help us configure the equipment to reduce signal loss when we conduct future air taxi flight tests.” Working in the Mobile Operations Facility at NASA’s Armstrong Flight Research Center in Edwards, California, NASA Advanced Air Mobility researcher Dennis Iannicca adjusts a control board to capture Automatic Dependent Surveillance-Broadcast (ADS-B) data during test flights. The data will be used to understand ADS-B signal loss scenarios for air taxi flights in urban areas.NASA/Steve Freeman The September flights at NASA Armstrong built upon earlier tests of ADS-B in different environments. In June, researchers at NASA’s Glenn Research Center in Cleveland flew the Pilatus PC-12 and found a consistent ADS-B signal between the aircraft and communications antennas mounted on the roof of the center’s Aerospace Communications Facility. Data from these flights helped researchers plan out the recent tests at NASA Armstrong. In December 2020, test flights performed under NASA’s Advanced Air Mobility National Campaign used an OH-58C Kiowa helicopter and ground-based ADS-B stations at NASA Armstrong to collect baseline signal information. NASA’s research in ADS-B signals and other communication, navigation, and surveillance systems will help revolutionize U.S. air transportation. Air Mobility Pathfinders researchers will evaluate the data from the three separate flight tests to understand the different signal transmission conditions and equipment needed for air taxis and drones to safely operate in the National Air Space. NASA will use the results of this research to design infrastructure to support future air taxi communication, navigation, and surveillance research and to develop new ADS-B-like concepts for uncrewed aircraft systems.
