WALLOPS ISLAND, Virginia—Just 10 months ago, NASA asked three companies if they could do something nobody had done before. Could they build and launch a satellite to save a $500 million astronomy mission at risk of crashing back to Earth? What's more, could they do it in less than a year on a tight budget?
Katalyst Space Technologies, a startup founded in 2020, presented the most compelling solution. "They came back with a response that was technically and programmatically plausible, and then we were like, 'Yeah, let’s do it,'" said Shawn Domagal-Goldman, director of NASA's astrophysics division.
That was in August of last year. In September, NASA awarded Katalyst a $30 million contract to build, test, and launch a small satellite to chase down Swift and latch onto it with three robotic arms. Then, Katalyst's Link servicing spacecraft will boost Swift's orbit back to a safe operating altitude, allowing it to resume scientific observations. Easier said than done.

NASA’s Curiosity rover and its mission to investigate whether Mars could have ever supported microbial life have taken one step closer to achieving its goal, with one of the most significant discoveries in the ongoing search for evidence of life on the Red Planet.
While exploring Gale Crater, NASA’s robotic rover uncovered a sample in 2020 and, using a chemical technique, determined that 21 carbon-based molecules were preserved in the clay-rich sedimentary rock. This also included seven that had never been identified on Mars before.
While the discovery does not definitively point to life on the Red Planet, it does strengthen the case that Mars has the chemical conditions to support life.
According to scientists, the most remarkable aspect of the discovery is not the molecules themselves, but their preservation
“The actual organic components they found are not strong evidence for life,” said Texas A&M University astrobiologist and geobiologist Dr. Michael Tice in a statement. Tice acknowledged that these compounds may also have evolved through abiotic processes, including formation in meteorites or other non-biological pathways.
“These organics were likely preserved in the rocks for a very long time, possibly billions of years, despite radiation and other harsh conditions on Mars,” Tice said.
“It blows my mind.”
Organic molecules are critical building blocks of life, but they can also form through non-biological processes, such as geological reactions or meteorite delivery. Similar preserved compounds on Earth help scientists study ancient environments, and their discovery on Mars provides new clues about the planet’s billion-year-old history.
“Studying how those compounds vary between different rocks can tell a story of how life and environments changed,” Tice recently said in a statement issued by Texas A&M. “Finding organics stored in similar ways on Mars tells us that there could be similar stories preserved there as well.”
The findings also suggest that Martian rocks may contain evidence from a time before life began, a record of sorts that Earth’s past geology has mostly erased.
“It is even possible that some Mars rocks will tell us about times when there was no life there,” he said, with organics formed instead through prebiotic chemistry or delivered from space. “We do not have an equivalent record of such a time preserved on Earth.”
The findings build on earlier research by Tice and his team that identified possible biosignatures in Mars rocks studied by NASA’s Perseverance rover.
Tice suggests, “When we looked even closer, we saw things that are easy to explain with early Martian life but very difficult to explain with only geological processes.”
The rocks contained organic carbon and key elements connected to microbial energy sources, along with chemical patterns that may show redox reactions (processes often associated with life on Earth).
“With the right collection, we could find the next step in evidence for past life on Mars or learn about the kinds of processes that eventually led to life on our planet.”
Tice and his colleagues will continue their work exploring the Martian land.
“I’m continuing to study the record of early Martian evolution as part of the PIXL instrument team on the Perseverance rover,” he said.
“In addition, I’m comparing how organisms affected some of the oldest sediments on Earth — now preserved in rocks in South Africa—with the potential biosignatures we discovered on Mars.”
Additional details about Tice and his team’s work can be found in a pair of papers, “Diverse organic molecules on Mars revealed by the first SAM TMAH experiment,” which appeared in Nature Communications, and “Redox-driven mineral and organic associations in Jezero Crater, Mars,” which was published in the journal Nature.

An experimental aircraft just achieved a “major milestone” that NASA officials say brings the future of quiet supersonic flight closer to being a reality.
The test flights involved the American space agency’s secretive X-59 aircraft, which reportedly reached speeds of 1.4 Mach—roughly 924 miles per hour—during a flight last Friday.
Reaching an altitude of 55,000 feet, the experimental aircraft’s speed and height during last week’s test flight met the conditions the agency says are required for future flights aiming to achieve supersonic flight without the noisy booms it usually generates.
In a statement, NASA said the aircraft’s tests are far from complete, although Friday’s test marks a significant milestone toward reaching its current mission goals.
“The X-59 still has months of performance testing ahead, but after those are complete, NASA’s Quesst mission will fly the aircraft over several U.S. communities to collect data on public perception of the quiet sonic thump it will make at supersonic speeds,” NASA’s statement on Friday read. “Those community overflights will include flights at Mach 1.4 and 55,000 feet.”
Last week’s test occurred within days of an earlier takeoff that sent the X-59 on its first successful supersonic flight, where the plane reached a top speed of Mach 1.1.
The earlier test also marked a leap forward for the Quesst mission, which is in the process of completing several crucial steps that are expanding the X-59’s capabilities.
Deployed for test flights at various speeds and at different altitudes, flight engineers are currently gauging the aircraft’s flight envelope by having it perform in a range of different flight conditions.
During its current test flights, NASA said the supersonic aircraft was accompanied by a NASA F-15 research aircraft, which still produces a sonic boom when it flies, unlike the X-59. NASA engineers plan to mount a shock-sensing probe on the accompanying aircraft during future flights, which the agency says will collect vital information about the shock waves the experimental aircraft produces.
The resulting experiments will help engineers measure the exact capabilities of the new aircraft and its supersonic performance.
Although designed to function as a “quiet” supersonic aircraft, the X-59 still produces audible signatures, which NASA likens more to being a soft “thump” than a sonic boom.
During its final testing phases, the X-59’s supersonic acoustic signature will also be measured.
If all goes according to plan, the supersonic aircraft will complete its full round of testing in the months ahead, marking a successful series of demonstrations that it meets all the requirements for quiet flight under a range of different altitudes and other flight conditions.
Ultimately, the technologies being innovated by this experimental plane will help to enable the first supersonic flight over land in decades, paving the way toward a new future of commercial flight faster than the speed of sound.

Scientists from the Southwest Research Institute’s Center for Lunar Origin and Evolution (CLOE) have revealed new models of the Moon’s oldest and largest impact crater, the South Pole-Aitken (SPA) basin, providing fresh insights into the event and resulting material deposition on the lunar surface.
The SwRI team behind the new models, which is part of NASA’s Solar System Exploration Research Virtual Institute, said such details will help prepare future Artemis astronauts for what they could encounter during their upcoming missions.
In a statement announcing the new models, Dr. William Bottke, director of CLOE and executive director of SwRI’s Science Directorate in Boulder, Colorado, said that the basin is an attractive potential target for future Artemis missions since it offers a “rare opportunity” to study an earlier era in the Moon’s history.
“The collision struck the lunar surface with such force that it may have excavated material from deep inside the Moon, including portions of the lunar mantle,” explained the co-author of the impact study detailing the new research.
Although previous studies have modeled impacts that may have caused the Moon’s oldest and largest crater, the team’s new effort has revealed new evidence about the composition of the impacting object and its likely direction and angle.
“Our simulation produces the right shape and nature of the impact basin,” explained the impact study’s lead author, Dr. Shigeru Wakita of Purdue University. “It also tells us about the projectile that created it and the direction of the impact.”
For example, the new model suggests that the object was not a single, uniform object. Instead, the team found that the impactor was likely a “differentiated” object, such as a protoplanet or asteroid, composed of rock and surrounded by an iron core. The models also found that the object approached from the north “at a low angle” before impacting the Moon’s surface on a southward trajectory.
According to the impact study authors, the impact excavated a deep, “asymmetric” cavity and generated enough energy to melt the rock within the crater’s central basin, resulting in the SPA basin’s elongated, tapered shape. Their models also indicated that the object’s lunar collision “lofted” large amounts of material into the air. Critically, their models also revealed that material from both the lunar crust and mantle was likely ejected before ultimately settling back onto the basin floor.
To help potential future lunar astronauts, including members of NASA’s Artemis mission, target the most scientifically valuable lunar samples, a second companion study explored the effects of gravity on ejecta distribution beneath and around the impact basin. According to the team behind that effort, their effort involved direct comparisons of high-resolution gravity data with models. Specifically, they wanted to determine if pieces of the Moon’s crust and mantle were included in the ejection.
After comparing the two, the authors of the second study determined that the SPA basin “likely contains substantial amounts of mantle-derived rocks” both within its interior and mixed into the wider ejecta blanket surrounding the basin. Also critical for future missions, the analysis revealed that this material was not all scattered during the initial impact.
Instead, the new models showed that subsequent, smaller impacts appear to have “excavated” these underlying mantle deposits. As a result, the team suggests that there is likely enough material on the surface of the Moon’s oldest and largest crater “where it could be readily sampled by robotic rovers or astronauts during future missions.”
When discussing the significance of the gravity study’s findings, lead author Dr. Gabriel Gowman of the University of Arizona said that before now, the “precise distribution” of lunar mantle material on the Moon’s surface “has been a big unknown.” For example, some previous theories suggested that the deepest ejecta might be found only in parts of the basin that are not currently included in planned Artemis missions.
Now, the team’s new models suggest that the impact that formed the SPA basin “ejected enough deep material to form a significant deposit that should still be accessible today.” More importantly, Dr. Gowman added, some of that scientifically valuable mantle material “at a trace level” may exist in regions currently under consideration for upcoming Artemis landings. Taken together, Bottke said, the two studies can provide a “powerful roadmap” for future lunar scientific missions to the Moon’s oldest and largest crater.
“It tells us not just how SPA formed, but where to look for the rocks that can answer some of our biggest questions about the Moon’s origin and evolution,” the researcher explained.
