Rebecca Mataya is a budget analyst at NASA’s Stennis Space Center. “Whether you are an engineer, analyst, lawyer, technician, communicator or innovator, there is a place for you here at NASA,” she said. “Every skill contributes to the greater mission of pushing the boundaries of exploration, discovery, and progress. If you have a passion, determination, and willingness to learn, NASA is a place where you can grow and leave a lasting impact on the future of space.”NASA/Stennis A career path can unfold in unexpected ways. Ask NASA’s Rebecca Mataya. The journey to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, was not planned but “meant to be,” she said. While working for a local business, the Picayune, Mississippi, native frequently delivered items to NASA Stennis. While making a delivery, Mataya noticed a construction worker who needed directions while waiting to receive a NASA Stennis visitor’s badge. “I stepped in by offering a map and highlighting the way,” Mataya said. This small moment of initiative caught the attention of the receptionist, who mentioned an opening at NASA Stennis. She noted that Mataya’s approach to the situation displayed the NASA Stennis culture of hospitality and a can-do attitude. “The rest is history,” she said. “Looking back, it was not just about finding a job – it was about NASA Stennis finding me, and me discovering a place where I would build a fulfilling career.” Since the first day of work when Mataya walked into NASA Stennis “in complete awe,” she has felt like every day is a learning experience filled with “wow” moments, like seeing a test stand up close and meeting rocket engineers. The Carriere, Mississippi, resident worked as a support contractor from 2008 to 2022, filling various roles from lead security support specialist to technical writer and program manager. Her career path has progressed, where each role built upon the previous. As a budget analyst in the NASA Stennis Office of the Chief Financial Officer since 2022, Mataya oversees the planning, programing, budgeting, and execution of funds for all Office of Strategic Infrastructure work within the NASA Stennis Center Operations Directorate. She also manages budgets for the NASA Stennis Construction of Facilities projects, and the congressionally approved Supplemental Funding portfolio. “It is a role that requires adaptability, strategic thinking, and financial oversight,” she said. “I have cultivated these skills through years of experience, but more than that, it is a role that allows me to contribute something meaningful to the future of NASA and space exploration.” Mataya will complete a master’s degree in Business Administration from Mississippi State University in May. She previously earned her bachelor’s degree from Mississippi State and an associate degree from Pearl River Community College. “My career has been shaped by growth and achievement, but the greatest highlight has always been the incredible people I have had the privilege of working with,” she said. “Walking the halls of NASA, where top leaders recognize me by name, is a testament to the trust and relationships I have built over the years.” Mataya said supervisors have consistently entrusted her with more complex projects, confident in her ability to rise to the challenge and deliver results. As a result, she has had opportunities to mentor interns and early-career professionals, guiding them as others once guided her. “Seeing my colleagues succeed and knowing they have reached their goals, and championing their progress along the way, remains one of the most rewarding aspects of my career,” she said. Mataya knows from experience that NASA Stennis offers opportunity and a supportive environment, not only for employees looking for career growth, but to customers seeking world-class testing facilities. “NASA Stennis is a place where collaboration thrives,” she said. “It is where NASA, tenants, and commercial partners come together as one cohesive community with a culture of mutual respect, support, and an unwavering commitment to excellence. As America’s largest rocket propulsion test site, NASA Stennis is evolving, and I look forward to seeing how our technological advancements attract new commercial partners and expand NASA’s capabilities.” View the full article

ESA/Hubble & NASA, D. Thilker The subject of today’s NASA/ESA Hubble Space Telescope image is the stunning spiral galaxy NGC 5530. This galaxy is situated 40 million light-years away in the constellation Lupus, the Wolf, and classified as a ‘flocculent’ spiral, meaning its spiral arms are patchy and indistinct. While some galaxies have extraordinarily bright centers that host a feasting supermassive black hole, the bright source near the center of NGC 5530 is not an active black hole but a star within our own galaxy, only 10,000 light-years from Earth. This chance alignment gives the appearance that the star is at the dense heart of NGC 5530. If you pointed a backyard telescope at NGC 5530 on the evening of September 13, 2007, you would have seen another bright point of light adorning the galaxy. That night, Australian amateur astronomer Robert Evans discovered a supernova, named SN 2007IT, by comparing NGC 5530’s appearance through the telescope to a reference photo of the galaxy. While it’s remarkable to discover even one supernova using this painstaking method, Evans has in fact discovered more than 40 supernovae this way! This particular discovery was truly serendipitous: it’s likely that the light from the supernova completed its 40-million-year journey to Earth just days before Evans spotted the explosion.

From left are Mission Specialist Kimiya Yui from JAXA (Japan Aerospace Exploration Agency), Commander NASA astronaut Zena Cardman, Mission Specialist Oleg Platonov of Roscosmos, and Pilot NASA astronaut Mike Fincke.Credit: NASA As part of NASA’s SpaceX Crew-11 mission, four crew members from three space agencies will launch in the coming months to the International Space Station for a long-duration science expedition aboard the orbiting laboratory. NASA astronauts Commander Zena Cardman and Pilot Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Mission Specialist Kimiya Yui, and Roscosmos cosmonaut Mission Specialist Oleg Platonov will join crew members aboard the space station no earlier than July 2025. The flight is the 11th crew rotation with SpaceX to the station as part of NASA’s Commercial Crew Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future missions to the Moon, as well as benefit people on Earth. Cardman previously was assigned to NASA’s SpaceX Crew-9 mission, and Fincke previously was assigned to NASA’s Boeing Starliner-1 mission. NASA decided to reassign the astronauts to Crew-11 in overall support of planned activities aboard the International Space Station. Cardman carries her experience training as a commander on Dragon spacecraft, and Fincke brings long-duration spaceflight experience to this crew complement. Selected as a NASA astronaut in 2017, Cardman will conduct her first spaceflight. The Williamsburg, Virginia, native holds a bachelor’s degree in Biology and a master’s in Marine Sciences from the University of North Carolina at Chapel Hill. At the time of selection, she had begun pursuing a doctorate in Geosciences. Cardman’s research in geobiology and geochemical cycling focused on subsurface environments, from caves to deep sea sediments. Since completing initial training, Cardman has supported real-time station operations and lunar surface exploration planning. This will be Fincke’s fourth trip to the space station, having logged 382 days in space and nine spacewalks during Expedition 9 in 2004, Expedition 18 in 2008, and STS-134 in 2011, the final flight of space shuttle Endeavour. Throughout the past decade, Fincke has applied his expertise to NASA’s Commercial Crew Program, advancing the development and testing of the SpaceX Dragon and Boeing Starliner toward operational certification. The Emsworth, Pennsylvania, native is a distinguished graduate of the United States Air Force Test Pilot School and holds bachelors’ degrees from the Massachusetts Institute of Technology, Cambridge, in both Aeronautics and Astronautics, as well as Earth, Atmospheric and Planetary Sciences. He also has a master’s degree in Aeronautics and Astronautics from Stanford University in California. Fincke is a retired U.S. Air Force colonel with more than 2,000 flight hours in more than 30 different aircraft. With 142 days in space, this will be Yui’s second trip to the space station. After his selection as a JAXA astronaut in 2009, Yui flew as a flight engineer for Expedition 44/45 and became the first Japanese astronaut to capture JAXA’s H-II Transfer Vehicle. In addition to constructing a new experimental environment aboard Kibo, he conducted a total of 21 experiments for JAXA. In November 2016, Yui was assigned as chief of the JAXA Astronaut Group. He graduated from the School of Science and Engineering at the National Defense Academy of Japan in 1992. He later joined the Air Self-Defense Force at the Japan Defense Agency (currently Ministry of Defense). In 2008, Yui joined the Air Staff Office at the Ministry of Defense as a lieutenant colonel. The Crew-11 mission will be Platonov’s first spaceflight. Before his selection as a cosmonaut in 2018, Platonov earned a degree in Engineering from Krasnodar Air Force Academy in Aircraft Operations and Air Traffic Management. He also earned a bachelor’s degree in State and Municipal Management in 2016 from the Far Eastern Federal University in Vladivostok, Russia. Assigned as a test cosmonaut in 2021, he has experience in piloting aircraft, zero gravity training, scuba diving, and wilderness survival. For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.

NASA The instrument enclosure of NASA’s Near-Earth Object Surveyor is prepared for critical environmental tests inside the historic Chamber A at the Space Environment Simulation Laboratory at NASA’s Johnson Space Center in Houston in December 2024. Wrapped in silver thermal blanketing, the 12-foot-long (3.7-meter-long) angular structure was subjected to the frigid, airless conditions that the spacecraft will experience when in deep space. The cavernous thermal-vacuum test facility is famous for testing the Apollo spacecraft that traveled to the Moon in the 1960s and ’70s. The instrument enclosure is designed to protect the spacecraft’s infrared telescope while also removing heat from it during operations. After environmental testing was completed, the enclosure returned to NASA’s Jet Propulsion Laboratory in Southern California for further work, after which it will ship to the Space Dynamics Laboratory (SDL) in Logan, Utah, and be joined to the telescope. Both the instrument enclosure and telescope were assembled at JPL. As NASA’s first space-based detection mission specifically designed for planetary defense, NEO Surveyor will seek out, measure, and characterize the hardest-to-find asteroids and comets that might pose a hazard to Earth. While many near-Earth objects don’t reflect much visible light, they glow brightly in infrared light due to heating by the Sun. The spacecraft’s telescope, which has an aperture of nearly 20 inches (50 centimeters), features detectors sensitive to two infrared wavelengths in which near-Earth objects re-radiate solar heat.

From left to right, NASA Marshall engineers Carlos Diaz and John Luke Bili, U.S. Naval Research Laboratory mechanical engineer contractor Eloise Stump, and Marshall engineers Tomasz Liz, David Banks, and Elise Doan observe StarBurst in the cleanroom environment before it’s unboxed from its shipping container. The cleanroom environment at Marshall is designed to minimize contamination and protect the observatory’s sensitive instruments. Image Credit: NASA /Daniel Kocevski StarBurst, a wide-field gamma ray observatory, arrived at NASA’s Marshall Space Flight Center in Huntsville, Alabama, March 4 for environmental testing and final instrument integration. The instrument is designed to detect the initial emission of short gamma-ray bursts, a key electromagnetic indicator of neutron star mergers. “Gamma-ray bursts are among the most powerful explosions in the universe, and they serve as cosmic beacons that help us understand extreme physics, including black hole formation and the behavior of matter under extreme conditions,” said Dr. Daniel Kocevski, principal investigator of the StarBurst mission at NASA Marshall. According to Kocevski, neutron star mergers are particularly exciting because they produce gamma-ray bursts and gravitational waves, meaning scientists can study these events using two different signals – light and ripples in space time. Starburst Principal Investigator Dr. Daniel Kocevski, left, and Integration and Test Engineer Elise Doan, right, pose with the StarBurst instrument after it was unboxed in the cleanroom environment at NASA Marshall. The Naval Research Lab transferred the instrument to NASA in early March.Image Credit: NASA/Davy Haynes The merging of neutron stars forges heavy elements such as gold and platinum, revealing the origins of some of Earth’s building blocks. “By studying these gamma-ray bursts and the neutron star mergers that produce them, we gain insights into fundamental physics, the origins of elements, and even the expansion of the universe,” Kocevski said. “Neutron star mergers and gamma-ray bursts are nature’s laboratories for testing our understanding of the cosmos.” StarBurst will undergo flight vibration and thermal vacuum testing at Marshall in the Sunspot Thermal Vacuum Testing Facility. These tests ensure it can survive the rigors of launch and harsh environment of space. Final instrument integration will happen in the Stray Light Facility, which is a specialized environment to help identify and reduce unwanted light in certain areas of the optical systems. The StarBurst Multimessenger Pioneer is a wide-field gamma-ray observatory designed to detect the initial emission of short gamma-ray bursts, important electromagnetic indicators of neutron star mergers. With an effective area over five times that of the Fermi Gamma-ray Burst Monitor and complete visibility of the unobscured sky, StarBurst will conduct sensitive observations. NASA/Daniel Kocevski StarBurst is a collaborative effort led by NASA’s Marshall Space Flight Center, with partnerships with the U.S. Naval Research Laboratory, the University of Alabama Huntsville, the Universities Space Research Association, and the UTIAS Space Flight Laboratory. StarBurst was selected for development as part of the NASA Astrophysics Pioneers program, which supports lower-cost, smaller hardware missions to conduct compelling astrophysics science.

NASA’s Electrodynamic Dust Shield (EDS) successfully demonstrated its ability to remove regolith, or lunar dust and dirt, from its various surfaces on the Moon during Firefly Aerospace’s Blue Ghost Mission 1, which concluded on March 16. Lunar dust is extremely abrasive and electrostatic, which means it clings to anything that carries a charge. It can damage everything from spacesuits and hardware to human lungs, making lunar dust one of the most challenging features of living and working on the lunar surface. The EDS technology uses electrodynamic forces to lift and remove the lunar dust from its surfaces. The first image showcases the glass and thermal radiator surfaces, coated in a layer of regolith. As you slide to the left, the photo reveals the results after EDS activation. Dust was removed from both surfaces, proving the technology’s effectiveness in mitigating dust accumulation. This milestone marks a significant step toward sustaining long-term lunar and interplanetary operations by reducing dust-related hazards to a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. The EDS technology is paving the way for future dust mitigation solutions, supporting NASA’s Artemis campaign and beyond. NASA’s Electrodynamic Dust Shield was developed at Kennedy Space Center in Florida with funding from NASA’s Game Changing Development Program, managed by the agency’s Space Technology Mission Directorate.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Ice cover ebbs and flows through the seasons in the Arctic (left) and the Antarctic (right). Overall, ice cover has declined since scientists started tracking it half a century ago. Download this visualization from NASA’s Scientific Visualization Studio: https://svs.gsfc.nasa.gov/5099Trent Schindler/NASA’s Scientific Visualization Studio Winter sea ice cover in the Arctic was the lowest it’s ever been at its annual peak on March 22, 2025, according to NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder. At 5.53 million square miles (14.33 million square kilometers), the maximum extent fell below the prior low of 5.56 million square miles (14.41 million square kilometers) in 2017. In the dark and cold of winter, sea ice forms and spreads across Arctic seas. But in recent years, less new ice has been forming, and less multi-year ice has accumulated. This winter continued a downward trend scientists have observed over the past several decades. This year’s peak ice cover was 510,000 square miles (1.32 million square kilometers) below the average levels between 1981 and 2010. In 2025, summer ice in the Antarctic retreated to 764,000 square miles (1.98 million square kilometers) on March 1, tying for the second lowest minimum extent ever recorded. That’s 30% below the 1.10 million square miles (2.84 million square kilometers) that was typical in the Antarctic prior to 2010. Sea ice extent is defined as the total area of the ocean with at least 15% ice concentration. The reduction in ice in both polar regions has led to another milestone — the total amount of sea ice on the planet reached an all-time low. Globally, ice coverage in mid-February of this year declined by more than a million square miles (2.5 million square kilometers) from the average before 2010. Altogether, Earth is missing an area of sea ice large enough to cover the entire continental United States east of the Mississippi. “We’re going to come into this next summer season with less ice to begin with,” said Linette Boisvert, an ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It doesn’t bode well for the future.” To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Observations since 1978 show that ice cover has declined at both poles, leading to a downward trend in the total ice cover over the entire planet.

Microwave scanners can also penetrate through cloud cover, allowing for daily global observations. The DMSP data are augmented with historical sources, including data collected between 1978 and 1985 with the Nimbus-7 satellite that was jointly operated by NASA and the National Oceanic and Atmospheric Administration. “It’s not yet clear whether the Southern Hemisphere has entered a new norm with perennially low ice or if the Antarctic is in a passing phase that will revert to prior levels in the years to come,” said Walt Meier, an ice scientist with NSIDC.

X-ray: NASA/CXC/Technion/N. Keshet et al.; Illustration: NASA/CXC/SAO/M. Weiss People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space. Mining data from NASA’s Chandra X-ray Observatory, the team of astronomers studied the relics that one star left behind after it exploded. This “supernova archaeology” uncovered important clues about a star that self-destructed – probably more than a million years ago. Today, the system called GRO J1655-40 contains a black hole with nearly seven times the mass of the Sun and a star with about half as much mass. However, this was not always the case. Originally GRO J1655-40 had two shining stars. The more massive of the two stars, however, burned through all of its nuclear fuel and then exploded in what astronomers call a supernova. The debris from the destroyed star then rained onto the companion star in orbit around it, as shown in the artist’s concept. This artist’s impression shows the effects of the collapse and supernova explosion of a massive star. A black hole (right) was formed in the collapse and debris from the supernova explosion is raining down onto a companion star (left), polluting its atmosphere.CXC/SAO/M. Weiss With its outer layers expelled, including some striking its neighbor, the rest of the exploded star collapsed onto itself and formed the black hole that exists today. The separation between the black hole and its companion would have shrunk over time because of energy being lost from the system, mainly through the production of gravitational waves. When the separation became small enough, the black hole, with its strong gravitational pull, began pulling matter from its companion, wrenching back some of the material its exploded parent star originally deposited. While most of this material sank into the black hole, a small amount of it fell into a disk that orbits around the black hole. Through the effects of powerful magnetic fields and friction in the disk, material is being sent out into interstellar space in the form of powerful winds. This is where the X-ray archaeological hunt enters the story. Astronomers used Chandra to observe the GRO J1655-40 system in 2005 when it was particularly bright in X-rays. Chandra detected signatures of individual elements found in the black hole’s winds by getting detailed spectra – giving X-ray brightness at different wavelengths – embedded in the X-ray light. Some of these elements are highlighted in the spectrum shown in the inset. The team of astronomers digging through the Chandra data were able to reconstruct key physical characteristics of the star that exploded from the clues imprinted in the X-ray light by comparing the spectra with computer models of stars that explode as supernovae. They discovered that, based on the amounts of 18 different elements in the wind, the long-gone star destroyed in the supernova was about 25 times the mass of the Sun, and was much richer in elements heavier than helium in comparison with the Sun. This analysis paves the way for more supernova archaeology studies using other outbursts of double star systems. A paper describing these results titled “Supernova Archaeology with X-Ray Binary Winds: The Case of GRO J1655−40” was published in The Astrophysical Journal in May 2024. The authors of this study are Noa Keshet (Technion — Israel Institute of Technology), Ehud Behar (Technion), and Timothy Kallman (NASA’s Goddard Space Flight Center). NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

The artist’s illustration features a star and a black hole in a system called GRO J1655-40. Here, the black hole is represented by a black sphere to our upper right of center. The star is represented by a bright yellow sphere to our lower left of center. In this illustration, the artist captures the immensely powerful supernova as a black hole is created from the collapse of a massive star, with an intense burst of blurred beams radiating from the black sphere. The blurred beams of red, orange, and yellow light show debris from the supernova streaking across the entire image in rippling waves. These beams rain debris on the bright yellow star. When astronomers used the Chandra X-ray Observatory to observe the system in 2005, they detected signatures of individual elements embedded in the X-ray light. Some of those elements are highlighted in the spectrum graph shown in the inset, positioned at our upper lefthand corner. The graph’s vertical axis, on our left, indicates X-ray brightness from 0.0 up to 0.7 in intensity units. The horizontal axis, at the bottom of the graph, indicates Wavelength from 6 to 12 in units of Angstroms. On the graph, a tight zigzagging line begins near the top of the vertical axis, and slopes down toward the far end of the horizontal axis. The sharp dips show wavelengths where the light has been absorbed by different elements, decreasing the X-ray brightness. Some of the elements causing these dips have been labeled, including Silicon, Magnesium, Iron, Nickel, Neon, and Cobalt.

In the interest of stability, the Curiosity team prefers to have all six rover wheels on the ground before deploying its 7-foot-long robotic arm (2.1 meters), so they opted for remote sensing observations instead, then another drive higher in the canyon. Curiosity captured this image on March 23, 2025 — sol 4489, or Martian day 4,489 of the Mars Science Laboratory mission — at 15:24:49 UTC. NASA/JPL-Caltech Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center Earth planning date: Monday, March 24, 2025 If you’ve ever seen a geologist in the field, you may have seen a classic stance: one leg propped up on a rock, knee bent, head down looking at the rocks at their feet, and arm pointing to the distant stratigraphy. Today Curiosity decided to give us her best field geologist impression. The weekend drive went well and the rover traversed about 23 meters (about 75 feet), but ended with the right front wheel perched on an angular block. In the Front Hazcam image above, you can see the right front wheel on a small block, and the rover’s shadow with the mast staring out at all the exciting rocks to explore. Great pose, but not what we want for planning contact science! We like to have all six wheels on the ground for stability before deploying the robotic arm. So instead of planning contact science today, the team pivoted to a lot of remote sensing observations and another drive to climb higher in this canyon. I was on shift as Long Term Planner today, and it was fun to see the team quickly adapt to the change in plans. Today’s two-sol plan includes targeted remote sensing and a drive on the first sol, followed by an untargeted science block on the second sol. On Sol 4491, ChemCam will acquire a LIBS observation of a well-laminated block in our workspace named “Big Narrows,” followed by long-distance RMI observations coordinated with Mastcam to assess an interesting debris field at “Torote Bowl.” The team planned a large Mastcam mosaic to characterize the stratigraphy at Texoli butte from a different viewing geometry than we have previously captured. Mastcam will also be used to investigate active surface processes in the sandy troughs nearby, and an interesting fracture pattern at “Bronson Cave.” Then Curiosity will drive further to the south and take post-drive imaging to prepare for the next plan. On the second sol the team added an autonomously selected ChemCam AEGIS target, along with Navcam movies to monitor clouds, wind direction, and dust.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s X-59 quiet supersonic research aircraft sits on a ramp at Lockheed Martin Skunk Works in Palmdale, California, during sunset. The one-of-a-kind aircraft is powered by a General Electric F414 engine, a variant of the engines used on F/A-18 fighter jets. The engine is mounted above the fuselage to reduce the number of shockwaves that reach the ground. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight and enable future commercial travel over land – faster than the speed of sound.Lockheed Martin Corporation/Garry Tice The team behind NASA’s X-59 completed another critical ground test in March, ensuring the quiet supersonic aircraft will be able to maintain a specific speed during operation. The test, known as engine speed hold, is the latest marker of progress as the X-59 nears first flight this year. “Engine speed hold is essentially the aircraft’s version of cruise control,” said Paul Dees, NASA’s X-59 deputy propulsion lead at the agency’s Armstrong Flight Research Center in Edwards, California. “The pilot engages speed hold at their current speed, then can adjust it incrementally up or down as needed.” The X-59 team had previously conducted a similar test on the engine – but only as an isolated system. The March test verified the speed hold functions properly after integration into the aircraft’s avionics. “We needed to verify that speed hold worked not just within the engine itself but as part of the entire aircraft system.” Dees explained. “This test confirmed that all components – software, mechanical linkages, and control laws – work together as intended.” The successful test confirmed the aircraft’s ability to precisely control speed, which will be invaluable during flight. This capability will increase pilot safety, allowing them to focus on other critical aspects of flight operation. “The pilot is going to be very busy during first flight, ensuring the aircraft is stable and controllable,” Dees said. “Having speed hold offload some of that workload makes first flight that much safer.” The team originally planned to check the speed hold as part of an upcoming series of ground test trials where they will feed the aircraft with a robust set of data to verify functionality under both normal and failure conditions, known as aluminum bird tests. But the team recognized a chance to test sooner. “It was a target of opportunity,” Dees said. “We realized we were ready to test engine speed hold separately while other systems continued with finalizing their software. If we can learn something earlier, that’s always better.” With every successful test, the integrated NASA and Lockheed Martin team brings the X-59 closer to first flight, and closer to making aviation history through quiet supersonic technology.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) How can I see the northern lights? To see the northern lights, you need to be in the right place at the right time. Auroras are the result of charged particles and magnetism from the Sun called space weather dancing with the Earth’s magnetic field. And they happen far above the clouds. So you need clear skies, good space weather at your latitude and the higher, more polar you can be, the better. You need a lot of patience and some luck is always helpful. A smartphone can also really help confirm whether you saw a little bit of kind of dim aurora, because cameras are more sensitive than our eyes. The best months to see aurorae, statistically, are March and September. The best times to be looking are around midnight, but sometimes when the Sun is super active, it can happen any time from sunset to sunrise. You can also increase your chances by learning more about space weather data and a great place to do that is at the NOAA Space Weather Prediction Center. You can also check out my project, Aurorasaurus.org, where we have free alerts that are based on your location and we offer information about how to interpret the data. And you can also report and tell us if you were able to see aurora or not and that helps others. One last tip is finding a safe, dark sky viewing location with a great view of the northern horizon that’s near you.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A NASA F/A-18 research aircraft flies above California near NASA’s Armstrong Flight Research Center in Edwards, California, testing a commercial precision landing technology for future space missions. The Psionic Space Navigation Doppler Lidar (PSNDL) system is installed in a pod located under the right wing of the aircraft.NASA Nestled in a pod under an F/A-18 Hornet aircraft wing, flying above California, and traveling up to the speed of sound, NASA put a commercial sensor technology to the test. The flight tests demonstrated the sensor accuracy and navigation precision in challenging conditions, helping prepare the technology to land robots and astronauts on the Moon and Mars. The Psionic Space Navigation Doppler Lidar (PSNDL) system is rooted in NASA technology that Psionic, Inc. of Hampton, Virginia, licensed and further developed. They miniaturized the NASA technology, added further functionality, and incorporated component redundancies that make it more rugged for spaceflight. The PSNDL navigation system also includes cameras and an inertial measurement unit to make it a complete navigation system capable of accurately determining a vehicle’s position and velocity for precision landing and other spaceflight applications. NASA engineers and technicians install the Psionic Space Navigation Doppler Lidar (PSNDL) system into a testing pod on a NASA F/A-18 research aircraft ahead of February 2025 flight tests at NASA’s Armstrong Flight Research Center in Edwards, California.NASA The aircraft departed from NASA’s Armstrong Flight Research Center in Edwards, California, and conducted a variety of flight paths over several days in February 2025. It flew a large figure-8 loop and conducted several highly dynamic maneuvers over Death Valley, California, to collect navigation data at various altitudes, velocities, and orientations relevant for lunar and Mars entry and descent. Refurbished for these tests, the NASA F/A-18 pod can support critical data collection for other technologies and users at a low cost. Doppler Lidar sensors provide a highly accurate measurement of speed by measuring the frequency shift between laser light emitted from the sensor reflected from the ground. Lidar are extremely useful in sunlight-challenged areas that may have long shadows and stark contrasts, such as the lunar South Pole. Pairing PSNDL with cameras adds the ability to visually compare pictures with surface reconnaissance maps of rocky terrain and navigate to landing at interesting locations on Mars. All the data is fed into a computer to make quick, real-time decisions to enable precise touchdowns at safe locations.

Full image below. Credits: NASA, ESA, CSA, JADES Collaboration, J. Witstok (University of Cambridge/University of Copenhagen), P. Jakobsen (University of Copenhagen), A. Pagan (STScI), M. Zamani (ESA/Webb) Using the unique infrared sensitivity of NASA’s James Webb Space Telescope, researchers can examine ancient galaxies to probe secrets of the early universe. Now, an international team of astronomers has identified bright hydrogen emission from a galaxy in an unexpectedly early time in the universe’s history. The surprise finding is challenging researchers to explain how this light could have pierced the thick fog of neutral hydrogen that filled space at that time. The Webb telescope discovered the incredibly distant galaxy JADES-GS-z13-1, observed to exist just 330 million years after the big bang, in images taken by Webb’s NIRCam (Near-Infrared Camera) as part of the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES). Researchers used the galaxy’s brightness in different infrared filters to estimate its redshift, which measures a galaxy’s distance from Earth based on how its light has been stretched out during its journey through expanding space. Image A: JADES-GS-z13-1 in the GOODS-S field (NIRCam Image) The incredibly distant galaxy JADES-GS-z13-1, observed just 330 million years after the big bang, was initially discovered with deep imaging from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera). Now, an international team of astronomers definitively has identified powerful hydrogen emission from this galaxy at an unexpectedly early period in the universe’s history. JADES-GS-z-13 has a redshift (z) of 13, which is an indication of its age and distance. NASA, ESA, CSA, JADES Collaboration, J. Witstok (University of Cambridge/University of Copenhagen), P. Jakobsen (University of Copenhagen), A. Pagan (STScI), M. Zamani (ESA/Webb) Image B: JADES-GS-z13-1 (NIRCam Close-Up) This image shows the galaxy JADES GS-z13-1 (the red dot at center), imaged with NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. These data from NIRCam allowed researchers to identify GS-z13-1 as an incredibly distant galaxy, and to put an estimate on its redshift value. Webb’s unique infrared sensitivity is necessary to observe galaxies at this extreme distance, whose light has been shifted into infrared wavelengths during its long journey across the cosmos. NASA, ESA, CSA, JADES Collaboration, J. Witstok (University of Cambridge/University of Copenhagen), P. Jakobsen (University of Copenhagen), M. Zamani (ESA/Webb) The NIRCam imaging yielded an initial redshift estimate of 12.9. Seeking to confirm its extreme redshift, an international team lead by Joris Witstok of the University of Cambridge in the United Kingdom, as well as the Cosmic Dawn Center and the University of Copenhagen in Denmark, then observed the galaxy using Webb’s Near-Infrared Spectrograph instrument. In the resulting spectrum, the redshift was confirmed to be 13.0. This equates to a galaxy seen just 330 million years after the big bang, a small fraction of the universe’s present age of 13.8 billion years old. But an unexpected feature stood out as well: one specific, distinctly bright wavelength of light, known as Lyman-alpha emission, radiated by hydrogen atoms. This emission was far stronger than astronomers thought possible at this early stage in the universe’s development. “The early universe was bathed in a thick fog of neutral hydrogen,” explained Roberto Maiolino, a team member from the University of Cambridge and University College London. “Most of this haze was lifted in a process called reionization, which was completed about one billion years after the big bang. GS-z13-1 is seen when the universe was only 330 million years old, yet it shows a surprisingly clear, telltale signature of Lyman-alpha emission that can only be seen once the surrounding fog has fully lifted. This result was totally unexpected by theories of early galaxy formation and has caught astronomers by surprise.” Image C: JADES-GS-z13-1 Spectrum Graphic NASA’s James Webb Space Telescope has detected unexpected light from a distant galaxy. The galaxy JADES-GS-z13-1, observed just 330 million years after the big bang (corresponding to a redshift of z=13.05), shows bright emission from hydrogen known as Lyman-alpha emission. This is surprising because that emission should have been absorbed by a dense fog of neutral hydrogen that suffused the early universe. NASA, ESA, CSA, J. Witstok (University of Cambridge, University of Copenhagen), J. Olmsted (STScI) Before and during the era of reionization, the immense amounts of neutral hydrogen fog surrounding galaxies blocked any energetic ultraviolet light they emitted, much like the filtering effect of colored glass. Until enough stars had formed and were able to ionize the hydrogen gas, no such light — including Lyman-alpha emission — could escape from these fledgling galaxies to reach Earth. The confirmation of Lyman-alpha radiation from this galaxy, therefore, has great implications for our understanding of the early universe. “We really shouldn’t have found a galaxy like this, given our understanding of the way the universe has evolved,” said Kevin Hainline, a team member from the University of Arizona. “We could think of the early universe as shrouded with a thick fog that would make it exceedingly difficult to find even powerful lighthouses peeking through, yet here we see the beam of light from this galaxy piercing the veil. This fascinating emission line has huge ramifications for how and when the universe reionized.” The source of the Lyman-alpha radiation from this galaxy is not yet known, but it may include the first light from the earliest generation of stars to form in the universe. “The large bubble of ionized hydrogen surrounding this galaxy might have been created by a peculiar population of stars — much more massive, hotter, and more luminous than stars formed at later epochs, and possibly representative of the first generation of stars,” said Witstok. A powerful active galactic nucleus, driven by one of the first supermassive black holes, is another possibility identified by the team. This research was published Wednesday in the journal Nature. 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.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Starling swarm’s extended mission tested advanced autonomous maneuvering capabilities.NASA/Daniel Rutter As missions to low Earth orbit become more frequent, space traffic coordination remains a key element to efficiently operating in space. Different satellite operators using autonomous systems need to operate together and manage increasing workloads. NASA’s Starling spacecraft swarm recently tested a coordination with SpaceX’s Starlink constellation, demonstrating a potential solution to enhance space traffic coordination. Led by the Small Spacecraft Technology program at NASA’s Ames Research Center in California’s Silicon Valley, Starling originally set out to demonstrate autonomous planning and execution of orbital maneuvers with the mission’s four small spacecraft. After achieving its primary objectives, the Starling mission expanded to become Starling 1.5, an experiment to demonstrate maneuvers between the Starling swarm and SpaceX’s Starlink satellites, which also maneuver autonomously. Coordination in Low Earth Orbit Current space traffic coordination systems screen trajectories of spacecraft and objects in space and alert operators on the ground of potential conjunctions, which occur when two objects exceed an operator’s tolerance for a close approach along their orbital paths. Spacecraft operators can request notification at a range of probabilities, often anywhere from a 1 in 10,000 likelihood of a collision to 1 in 1,000,000 or lower. Conjunction mitigation between satellite operators requires manual coordination through calls or emails on the ground. An operator may receive a notification for a number of reasons including recently maneuvering their satellite, nearby space debris, or if another satellite adjusts its orbit. Once an operator is aware of a potential conjunction, they must work together with other operators to reduce the probability of a collision. This can result in time-consuming calls or emails between ground operations teams with different approaches to safe operations. It also means maneuvers may require several days to plan and implement. This timeline can be challenging for missions that require quick adjustments to capture important data. “Occasionally, we’ll do a maneuver that we find out wasn’t necessary if we could have waited before making a decision. Sometimes you can’t wait three days to reposition and observe. Being able to react within a few hours can make new satellite observations possible,” said Nathan Benz, project manager of Starling 1.5 at NASA Ames. Improving Coordination for Autonomous Maneuvering The first step in improving coordination was to develop a reliable way to signal maneuver responsibility between operators. “Usually, SpaceX takes the responsibility to move out of the way when another operator shares their predicted trajectory information,” said Benz. SpaceX and NASA collaborated to design a conjunction screening service, which SpaceX then implemented. Satellite operators can submit trajectories and receive conjunction data quickly, then accept responsibility to maneuver away from a potential conjunction. “For this experiment, NASA’s Starling accepted responsibility to move using the screening service, successfully tested our system’s performance, then autonomously planned and executed the maneuver for the NASA Starling satellite, resolving a close approach with a Starlink satellite,” said Benz. Through NASA’s Starling 1.5 experiment, the agency helped validate SpaceX’s Starlink screening service. The Office of Space Commerce within the U.S. Department of Commerce also worked with SpaceX to understand and assess the Starlink screening service. Quicker Response to Changes on Earth The time it takes to plan maneuvers in today’s orbital traffic environment limits the number of satellites a human operator can manage and their ability to collect data or serve customers. “A fully automated system that is flexible and adaptable between satellite constellations is ideal for an environment of multiple satellite operators, all of whom have differing criteria for mitigating collision risks,” said Lauri Newman, program officer for NASA’s Conjunction Assessment Risk Analysis program at the agency’s headquarters in Washington. Reducing the time necessary to plan maneuvers could open up a new class of missions, where quick responses to changes in space or on Earth’s surface are possible. Satellites capable of making quicker movements could adjust their orbital position to capture a natural disaster from above, or respond to one swarm member’s interesting observations, moving to provide a more thorough look. “With improved access and use of low Earth orbit and the necessity to provide a more advanced space traffic coordination system, Starling 1.5 is providing critical data. Starling 1.5 is the result of a successful partnership between NASA, the Department of Commerce, and SpaceX, maturing technology to solve such challenges,” said Roger Hunter, program manager of the Small Spacecraft Technology program. “We look forward to the sustained impact of the Starling technologies as they continue demonstrating advancements in spacecraft coordination, cooperation, and autonomy.” NASA Ames leads the Starling projects. NASA’s Small Spacecraft Technology program within the Space Technology Mission Directorate funds and manages the Starling mission.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) At left is NASA’s Perseverance Mars rover, with a circle indicating the location of the calibration target for the rover’s SHERLOC instrument. At right is a close-up of the calibration target. Along the bottom row are five swatches of spacesuit materials that scientists are studying as they de-grade.NASA/JPL-Caltech/MSSS The rover carries several swatches of spacesuit materials, and scientists are assessing how they’ve held up after four years on the Red Planet. NASA’s Perseverance rover landed on Mars in 2021 to search for signs of ancient microbial life and to help scientists understand the planet’s climate and geography. But another key objective is to pave the way for human exploration of Mars, and as part of that effort, the rover carries a set of five spacesuit material samples. Now, after those samples have endured four years of exposure on Mars’ dusty, radiation-soaked surface, scientists are beginning the next phase of studying them. The end goal is to predict accurately the usable lifetime of a Mars spacesuit. What the agency learns about how the materials perform on Mars will inform the design of future spacesuits for the first astronauts on the Red Planet. This graphic shows an illustration of a prototype astronaut suit, left, along with suit samples included aboard NASA’s Perseverance rover. They are the first spacesuit materials ever sent to Mars. NASA “This is one of the forward-looking aspects of the rover’s mission — not just thinking about its current science, but also about what comes next,” said planetary scientist Marc Fries of NASA’s Johnson Space Center in Houston, who helped provide the spacesuit materials. “We’re preparing for people to eventually go and explore Mars.” The swatches, each three-quarters of an inch square (20 millimeters square), are part of a calibration target used to test the settings of SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals), an instrument on the end of Perseverance’s arm. The samples include a piece of polycarbonate helmet visor; Vectran, a cut-resistant material used for the palms of astronaut gloves; two kinds of Teflon, which has dust-repelling nonstick properties; and a commonly used spacesuit material called Ortho-Fabric. This last fabric features multiple layers, including Nomex, a flame-resistant material found in firefighter outfits; Gore-Tex, which is waterproof but breathable; and Kevlar, a strong material used in bulletproof vests that makes spacesuits more rip-resistant. Martian Wear and Tear Mars is far from hospitable. It has freezing temperatures, fine dust that can stick to solar panels and spacesuits (causing wear and tear on the latter), and a surface rife with perchlorates, a kind of corrosive salt that can be toxic to humans. There’s also lots of solar radiation. Unlike Earth, which has a magnetic field that deflects much of the Sun’s radiation, Mars lost its magnetic field billions of years ago, followed by much of its atmosphere. Its surface has little protection from the Sun’s ultraviolet light (which is why researchers have looked into how rock formations and caves could provide astronauts some shielding). “Mars is a really harsh, tough place,” said SHERLOC science team member Joby Razzell Hollis of the Natural History Museum in London. “Don’t underestimate that — the radiation in particular is pretty nasty.” Razzell Hollis was a postdoctoral fellow at NASA’s Jet Propulsion Laboratory in Southern California from 2018 to 2021, where he helped prepare SHERLOC for arrival on Mars and took part in science operations once the rover landed. A materials scientist, Razzell Hollis has previously studied the chemical effects of sunlight on a new kind of solar panel made from plastic, as well as on plastic pollution floating in the Earth’s oceans. He likened those effects to how white plastic lawn chairs become yellow and brittle after years in sunlight. Roughly the same thing happens on Mars, but the weathering likely happens faster because of the high exposure to ultraviolet light there. The key to developing safer spacesuit materials will be understanding how quickly they would wear down on the Martian surface. About 50% of the changes SHERLOC witnessed in the samples happened within Perseverance’s first 200 days on Mars, with the Vectran appearing to change first. Another nuance will be figuring out how much solar radiation different parts of a spacesuit will have to withstand. For example, an astronaut’s shoulders will be more exposed — and likely encounter more radiation — than his or her palms. Next Steps The SHERLOC team is working on a science paper detailing initial data on how the samples have fared on Mars. Meanwhile, scientists at NASA Johnson are eager to simulate that weathering in special chambers that mimic the carbon dioxide atmosphere, air pressure, and ultraviolet light on the Martian surface. They could then compare the results generated on Earth while putting the materials to the test with those seen in the SHERLOC data. For example, the researchers could stretch the materials until they break to check if they become more brittle over time. “The fabric materials are designed to be tough but flexible, so they protect astronauts but can bend freely,” Fries said. “We want to know the extent to which the fabrics lose their strength and flexibility over time. As the fabrics weaken, they can fray and tear, allowing a spacesuit to leak both heat and air.” More About Perseverance A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover is characterizing the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet, and is the first mission to collect and cache Martian rock and regolith. NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA’s Mars Exploration Program (MEP) portfolio and the agency’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

How Can I See the Northern Lights? We Asked a NASA Expert

Credits: NASA, ESA, CSA, STScI, Heidi Hammel (AURA), Henrik Melin (Northumbria University), Leigh Fletcher (University of Leicester), Stefanie Milam (NASA-GSFC) Long-sought auroral glow finally emerges under Webb’s powerful gaze For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually strike the upper atmosphere. The energy released during these collisions creates the signature glow. In the past, astronomers have seen tantalizing hints of auroral activity on Neptune, for example, in the flyby of NASA’s Voyager 2 in 1989. However, imaging and confirming the auroras on Neptune has long evaded astronomers despite successful detections on Jupiter, Saturn, and Uranus. Neptune was the missing piece of the puzzle when it came to detecting auroras on the giant planets of our solar system. “Turns out, actually imaging the auroral activity on Neptune was only possible with Webb’s near-infrared sensitivity,” said lead author Henrik Melin of Northumbria University, who conducted the research while at the University of Leicester. “It was so stunning to not just see the auroras, but the detail and clarity of the signature really shocked me.” The data was obtained in June 2023 using Webb’s Near-Infrared Spectrograph. In addition to the image of the planet, astronomers obtained a spectrum to characterize the composition and measure the temperature of the planet’s upper atmosphere (the ionosphere). For the first time, they found an extremely prominent emission line signifying the presence of the trihydrogen cation (H3+), which can be created in auroras. In the Webb images of Neptune, the glowing aurora appears as splotches represented in cyan. Image A: Neptune’s Auroras – Hubble and Webb At the left, an enhanced-color image of Neptune from NASA’s Hubble Space Telescope. At the right, that image is combined with data from NASA’s James Webb Space Telescope. The cyan splotches, which represent auroral activity, and white clouds, are data from Webb’s Near-Infrared Spectrograph (NIRSpec), overlayed on top of the full image of the planet from Hubble’s Wide Field Camera 3. NASA, ESA, CSA, STScI, Heidi Hammel (AURA), Henrik Melin (Northumbria University), Leigh Fletcher (University of Leicester), Stefanie Milam (NASA-GSFC) “H3+ has a been a clear signifier on all the gas giants — Jupiter, Saturn, and Uranus — of auroral activity, and we expected to see the same on Neptune as we investigated the planet over the years with the best ground-based facilities available,” explained Heidi Hammel of the Association of Universities for Research in Astronomy, Webb interdisciplinary scientist and leader of the Guaranteed Time Observation program for the Solar System in which the data were obtained. “Only with a machine like Webb have we finally gotten that confirmation.” The auroral activity seen on Neptune is also noticeably different from what we are accustomed to seeing here on Earth, or even Jupiter or Saturn. Instead of being confined to the planet’s northern and southern poles, Neptune’s auroras are located at the planet’s geographic mid-latitudes — think where South America is located on Earth. This is due to the strange nature of Neptune’s magnetic field, originally discovered by Voyager 2 in 1989 which is tilted by 47 degrees from the planet’s rotation axis. Since auroral activity is based where the magnetic fields converge into the planet’s atmosphere, Neptune’s auroras are far from its rotational poles. The ground-breaking detection of Neptune’s auroras will help us understand how Neptune’s magnetic field interacts with particles that stream out from the Sun to the distant reaches of our solar system, a totally new window in ice giant atmospheric science. From the Webb observations, the team also measured the temperature of the top of Neptune’s atmosphere for the first time since Voyager 2’s flyby. The results hint at why Neptune’s auroras remained hidden from astronomers for so long. “I was astonished — Neptune’s upper atmosphere has cooled by several hundreds of degrees,” Melin said. “In fact, the temperature in 2023 was just over half of that in 1989.” Through the years, astronomers have predicted the intensity of Neptune’s auroras based on the temperature recorded by Voyager 2. A substantially colder temperature would result in much fainter auroras. This cold temperature is likely the reason that Neptune’s auroras have remained undetected for so long. The dramatic cooling also suggests that this region of the atmosphere can change greatly even though the planet sits over 30 times farther from the Sun compared to Earth. Equipped with these new findings, astronomers now hope to study Neptune with Webb over a full solar cycle, an 11-year period of activity driven by the Sun’s magnetic field. Results could provide insights into the origin of Neptune’s bizarre magnetic field, and even explain why it’s so tilted. “As we look ahead and dream of future missions to Uranus and Neptune, we now know how important it will be to have instruments tuned to the wavelengths of infrared light to continue to study the auroras,” added Leigh Fletcher of Leicester University, co-author on the paper. “This observatory has finally opened the window onto this last, previously hidden ionosphere of the giant planets.” These observations, led by Fletcher, were taken as part of Hammel’s Guaranteed Time Observation program 1249. The team’s results have been published in Nature Astronomy. 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 (European Space Agency) and CSA (Canadian Space Agency). Downloads Click any image to open a larger version.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Double Asteroid Redirection Test required extreme precision in mission planning to achieve its mission of impacting an asteroid. The founders of Continuum Space worked on astrodynamics relating to this mission, which they used to inform their product.NASA Planning space missions is a very involved process, ensuring orbits are lined up and spacecraft have enough fuel is imperative to the long-term survival of orbital assets. Continuum Space Systems Inc. of Pasadena, California, produces a cloud-based platform that gives mission planners everything they need to certify that their space resources can accomplish their goals. Continuum’s story begins at NASA’s Jet Propulsion Laboratory in Southern California. Loic Chappaz, the company’s co-founder, started at JPL as an intern working on astrodynamics related to NASA’s Double Asteroid Redirection Test. There he met Leon Alkalai, a JPL technical fellow who spent his 30-year career at the center planning deep space missions. After Alkalai retired from NASA, he founded Mandala Space Ventures, a startup that explored several avenues of commercial space development. Chappaz soon became Mandala’s first employee, but to plan their future, Mandala’s leadership began thinking about the act of planning itself. Because the staff had decades of combined experience at JPL, they knew the center had the building blocks for the software they needed. After licensing several pieces of software from JPL, the company began building planning systems that were highly adaptable to any space mission they could come up with. Mandala eventually evolved into a venture firm that incubated space-related startups. However, because Mandala had invested considerably in developing mission-planning tools, further development could be performed by a new company, and Continuum was fully spun off from Mandala in 2021. Continuum’s platform includes several features for mission planners, such as plotting orbital maneuvers and risk management evaluations. Some of these are built upon software licensed from the Jet Propulsion Laboratory.Continuum Space Systems Inc. Continuum’s tools are designed to take a space mission from concept to completion. There are three different components to their “mission in a box” — design, build and test, and mission operations. The base of these tools are several pieces of software developed at NASA. As of 2024, several space startups have begun planning missions with Continuum’s NASA-inspired software, as well as established operators of satellite constellations. From Continuum to several startups, NASA technologies continue to prove a valuable foundation for the nation’s space economy.

NASA Technicians do final checks on NASA’s Spirit rover in this image from March 28, 2003. The rover – and its twin, Opportunity – studied the history of climate and water at sites on Mars where conditions may once have been favorable to life. Each rover is about the size of a golf cart and seven times heavier (about 405 pounds or 185 kilograms) than the Sojourner rover launched on the Mars Pathfinder to Mars mission in 1996. Spirit and Opportunity were sent to opposite sides of Mars to locations that were suspected of having been affected by liquid water in the past. Spirit was launched first, on June 10, 2003. Spirit landed on the Martian surface on Jan. 3, 2004, about 8 miles (13.4 kilometers) from the planned target and inside the Gusev crater. The site became known as Columbia Memorial Station to honor the seven astronauts killed when the space shuttle Columbia broke apart Feb. 1, 2003, as it returned to Earth. The plaque commemorating the STS-107 Space Shuttle Columbia crew can be seen in the image above. Spirit operated for 6 years, 2 months, and 19 days, more than 25 times its original intended lifetime, traveling 4.8 miles (7.73 kilometers) across the Martian plains.
