The experiment’s two key instruments will demonstrate our ability to extract and analyze lunar soil to better understand the lunar environment and subsurface resources, paving the way for sustainable human exploration under the agency’s Artemis campaign for the benefit of all.
Its two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains (TRIDENT) will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations (MSOLO) will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to help us better understand the Moon’s surface and how to work with and on it.
“The ability to drill and analyze samples at the same time allows us to gather insights that will shape the future of lunar resource utilization,” said Jackie Quinn, PRIME-1 project manager at NASA’s Kennedy Space Center in Florida. “Human exploration of the Moon and deep space will depend on making good use of local resources to produce life-sustaining supplies necessary to live and work on another planetary body.”
The PRIME-1 experiment is one of the NASA payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center no earlier than Wednesday, Feb. 26, on Intuitive Machines’ Athena lunar lander and explore the lunar soil in Mons Mouton, a lunar plateau near the Moon’s South Pole.
Developed by Honeybee Robotics, a Blue Origin Company, TRIDENT is a rotary percussive drill designed to excavate lunar regolith and subsurface material up to 3.3 feet (1 meter) deep. The drill will extract samples, each about 4 inches (10 cm) in length, allowing scientists to analyze how trapped and frozen gases are distributed at different depths below the surface.
The TRIDENT drill is equipped with carbide cutting teeth to penetrate even the toughest lunar materials. Unlike previous lunar drills used by astronauts during the Apollo missions, TRIDENT will be controlled from Earth. The drill may provide key information about subsurface soil temperatures as well as gain key insight into the mechanical properties of the lunar South Pole soil. Learning more about regolith temperatures and properties will greatly improve our understanding of the environments where lunar resources may be stable, revealing what resources may be available for future Moon missions.
A commercial off-the-shelf mass spectrometer, MSOLO, developed by INFICON and made suitable for spaceflight at Kennedy, will analyze any gas released from the TRIDENT drilled samples, looking for the potential presence of water ice and other gases trapped beneath the surface. These measurements will help scientists understand the Moon’s potential for resource utilization.
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA is one of many customers on future flights. PRIME-1 was funded by NASA’s Space Technology Mission Directorate Game Changing Development program.

NASA’s Curiosity Mars rover captured these drifting noctilucent, or twilight, clouds in a 16-minute recording on Jan. 17. (This looping clip has been speeded up about 480 times.) The white plumes falling out of the clouds are carbon dioxide ice that would evaporate closer to the Martian surface.NASA/JPL-Caltech/MSSS/SSI While the Martian clouds may look like the kind seen in Earth’s skies, they include frozen carbon dioxide, or dry ice.
Red-and-green-tinted clouds drift through the Martian sky in a new set of images captured by NASA’s Curiosity rover using its Mastcam — its main set of “eyes.” Taken over 16 minutes on Jan. 17 (the 4,426th Martian day, or sol, of Curiosity’s mission), the images show the latest observations of what are called noctilucent (Latin for “night shining”), or twilight clouds, tinged with color by scattering light from the setting Sun.
Sometimes these clouds even create a rainbow of colors, producing iridescent, or “mother-of-pearl” clouds. Too faint to be seen in daylight, they’re only visible when the clouds are especially high and evening has fallen.
Martian clouds are made of either water ice or, at higher altitudes and lower temperatures, carbon dioxide ice. (Mars’ atmosphere is more than 95% carbon dioxide.) The latter are the only kind of clouds observed at Mars producing iridescence, and they can be seen near the top of the new images at an altitude of around 37 to 50 miles (60 to 80 kilometers). They’re also visible as white plumes falling through the atmosphere, traveling as low as 31 miles (50 kilometers) above the surface before evaporating because of rising temperatures. Appearing briefly at the bottom of the images are water-ice clouds traveling in the opposite direction roughly 31 miles (50 kilometers) above the rover.
Dawn of Twilight Clouds
Twilight clouds were first seen on Mars by NASA’s Pathfinder mission in 1997; Curiosity didn’t spot them until 2019, when it acquired its first-ever images of iridescence in the clouds. This is the fourth Mars year the rover has observed the phenomenon, which occurs during early fall in the southern hemisphere.
Mark Lemmon, an atmospheric scientist with the Space Science Institute in Boulder, Colorado, led a paper summarizing Curiosity’s first two seasons of twilight cloud observations, which published late last year in Geophysical Research Letters. “I’ll always remember the first time I saw those iridescent clouds and was sure at first it was some color artifact,” he said. “Now it’s become so predictable that we can plan our shots in advance; the clouds show up at exactly the same time of year.”
Each sighting is an opportunity to learn more about the particle size and growth rate in Martian clouds. That, in turn, provides more information about the planet’s atmosphere.
Cloud Mystery
One big mystery is why twilight clouds made of carbon dioxide ice haven’t been spotted in other locations on Mars. Curiosity, which landed in 2012, is on Mount Sharp in Gale Crater, just south of the Martian equator. Pathfinder landed in Ares Vallis, north of the equator. NASA’s Perseverance rover, located in the northern hemisphere’s Jezero Crater, hasn’t seen any carbon dioxide ice twilight clouds since its 2021 landing. Lemmon and others suspect that certain regions of Mars may be predisposed to forming them.
A possible source of the clouds could be gravity waves, he said, which can cool the atmosphere: “Carbon dioxide was not expected to be condensing into ice here, so something is cooling it to the point that it could happen. But Martian gravity waves are not fully understood and we’re not entirely sure what is causing twilight clouds to form in one place but not another.”
Mastcam’s Partial View
The new twilight clouds appear framed in a partially open circle. That’s because they were taken using one of Mastcam’s two color cameras: the left 34 mm focal length Mastcam, which has a filter wheel that is stuck between positions. Curiosity’s team at NASA’s Jet Propulsion Laboratory in Southern California remains able to use both this camera and the higher-resolution right 100 mm focal length camera for color imaging.
The rover recently wrapped an investigation of a place called Gediz Vallis channel and is on its way to a new location that includes boxwork — fractures formed by groundwater that look like giant spiderwebs when viewed from space.
More recently, Curiosity visited an impact crater nicknamed “Rustic Canyon,” capturing it in images and studying the composition of rocks around it. The crater, 67 feet (20 meters) in diameter, is shallow and has lost much of its rim to erosion, indicating that it likely formed many millions of years ago. One reason Curiosity’s science team studies craters is because the cratering process can unearth long-buried materials that may have better preserved organic molecules than rocks exposed to radiation at the surface. These molecules provide a window into the ancient Martian environment and how it could have supported microbial life billions of years ago, if any ever formed on the Red Planet.

2 Min Read Advanced Modeling Enhances Gateway’s Lunar Dust Defense

Credits: NASA/Josh Litofsky NASA’s Artemis campaign aims to return humans to the Moon, develop a sustainable presence there, and lay the groundwork for the first crewed missions to Mars. As the agency prepares for longer stays on and around the Moon, engineers are working diligently to understand the complex behavior of lunar dust, the sharp, jagged particles that can cling to spacesuits and jam equipment.
Lunar dust has posed a problem since astronauts first encountered it during the Apollo missions. Ahead of more frequent and intense contact with dust, NASA is developing new strategies to protect equipment as astronauts travel between the Moon and spacecraft like Gateway, humanity’s first lunar space station.
Josh Litofsky, systems engineer at NASA’s Johnson Space Center, scoops material designed to behave like lunar dust to test how it adheres to Gateway materials. NASA/Bill Stafford Unlike Apollo-era spacecraft that faced lunar dust exposure just once, Gateway will encounter it each time a Human Landing System spacecraft returns to the space station from the lunar South Pole region. Dust could enter Gateway’s environment, risking damage to science instruments, solar arrays, robotic systems, and other important hardware.
Josh Litofsky is the principal investigator and project manager leading a Gateway lunar dust adhesion testing campaign at NASA’s Johnson Space Center in Houston. His team tracks how the dust interacts with materials used to build Gateway.
An artist’s rendering of the Gateway lunar space station in polar orbit around the Moon. NASA/Alberto Bertolin “The particles are jagged from millions of years of micrometeoroid impacts, sticky due to chemical and electrical forces, and extremely small,” Litofsky said. “Even small amounts of lunar dust can have a big impact on equipment and systems.”
Litofksy’s work seeks to validate the Gateway On-orbit Lunar Dust Modeling and Analysis Program (GOLDMAP), developed by Ronald Lee, also of Johnson Space Center. By considering factors such as the design and configuration of the space station, the materials used, and the unique conditions in lunar orbit, GOLDMAP helps predict how dust may move and settle on Gateway’s external surfaces.
Josh Litofsky, systems engineer at NASA’s Johnson Space Center, places a sample holder inside a vacuum chamber to test how lunar dust sticks to Gateway materials. NASA/Bill StaffordNASA/Bill Stafford Early GOLDMAP simulations have shown that lunar dust can form clouds around Gateway, with larger particles sticking to surfaces.
The data from these tests and simulations will help NASA safeguard Gateway, to ensure the space station’s longevity during the next era of lunar exploration.
The lessons learned managing lunar dust and other harsh conditions through Gateway and Artemis will prepare NASA and its international partners for missions deeper into the cosmos

Video: 00:02:05 This is a new artist’s animation of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope.
Gaia has changed our impression of the Milky Way. Even seemingly simple ideas about the nature of our galaxy’s central bar and the spiral arms have been overturned. Gaia has shown us that it has more than two spiral arms and that they are less prominent than we previously thought. In addition, Gaia has shown that its central bar is more inclined with respect to the Sun.
No spacecraft can travel beyond our galaxy, so we can’t take a selfie, but Gaia is giving us the best insight yet of what our home galaxy looks like. Once all of Gaia’s observations collected over the past decade are made available in two upcoming data releases, we can expect an even sharper view of the Milky Way.
