Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side near the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Intuitive Machines NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) mission was designed to demonstrate technologies to help scientists better understand lunar resources ahead of crewed Artemis missions to the Moon. During the short-lived mission on the Moon, the performance of PRIME-1’s technology gave NASA teams reason to celebrate.
“The PRIME-1 mission proved that our hardware works in the harshest environment we’ve ever tested it in,” said Janine Captain, PRIME-1 co-principal investigator and research chemist at NASA’s Kennedy Space Center in Florida. “While it may not have gone exactly to plan, this is a huge step forward as we prepare to send astronauts back to the Moon and build a sustainable future there.”
Intuitive Machines’ IM-2 mission launched to the Moon on Feb. 26, 2025, from NASA Kennedy’s Launch Complex 39A, as part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. The IM-2 Nova-C lunar lander, named Athena, carried PRIME-1 and its suite of two instruments: a drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), designed to bring lunar soil to the surface; and a mass spectrometer, Mass Spectrometer Observing Lunar Operations (MSOLO), to study TRIDENT’s drill cuttings for the presence of gases that could one day help provide propellant or breathable oxygen to future Artemis explorers.
The IM-2 mission touched down on the lunar surface on March 6, just around 1,300 feet (400 meters) from its intended landing site of Mons Mouton, a lunar plateau near the Moon’s South Pole. The Athena lander was resting on its side inside a crater preventing it from recharging its solar cells, resulting in an end of the mission.
“We were supposed to have 10 days of operation on the Moon, and what we got was closer to 10 hours,” said Julie Kleinhenz, NASA’s lead systems engineer for PRIME-1, as well as the in-situ resource utilization system capability lead deputy for the agency. “It was 10 hours more than most people get so I am thrilled to have been a part of it.”
Kleinhenz has spent nearly 20 years working on how to use lunar resources for sustained operations. In-situ resource utilization harnesses local natural resources at mission destinations. This enables fewer launches and resupply missions and significantly reduces the mass, cost, and risk of space exploration. With NASA poised to send humans back to the Moon and on to Mars, generating products for life support, propellants, construction, and energy from local materials will become increasingly important to future mission success.
“In-situ resource utilization is the key to unlocking long-term exploration, and PRIME-1 is helping us lay this foundation for future travelers.” Captain said.
The PRIME-1 technology also set out to answer questions about the properties of lunar regolith, such as soil strength. This data could help inform the design of in-situ resource utilization systems that would use local resources to create everything from landing pads to rocket fuel during Artemis and later missions.
“Once we got to the lunar surface, TRIDENT and MSOLO both started right up, and performed perfectly. From a technology demonstrations standpoint, 100% of the instruments worked.” Kleinhenz said.
The lightweight, low-power augering drill built by Honeybee Robotics, known as TRIDENT, is 1 meter long and features rotary and percussive actuators that convert energy into the force needed to drill. The drill was designed to stop at any depth as commanded from the ground and deposit its sample on the surface for analysis by MSOLO, a commercial off-the-shelf mass spectrometer modified by engineers and technicians at NASA Kennedy to withstand the harsh lunar environment. Designed to measure the composition of gases in the vicinity of the lunar lander, both from the lander and from the ambient exosphere, MSOLO can help NASA analyze the chemical makeup of the lunar soil and study water on the surface of the Moon.
Once on the Moon, the actuators on the drill performed as designed, completing multiple stages of movement necessary to drill into the lunar surface. Prompted by commands from technicians on Earth, the auger rotated, the drill extended to its full range, the percussion system performed a hammering motion, and the PRIME-1 team turned on an embedded core heater in the drill and used internal thermal sensors to monitor the temperature change.
While MSOLO was able to perform several scans to detect gases, researchers believe from the initial data that the gases detected were all anthropogenic, or human in origin, such as gases vented from spacecraft propellants and traces of Earth water. Data from PRIME-1 accounted for some of the approximately 7.5 gigabytes of data collected during the IM-2 mission, and researchers will continue to analyze the data in the coming months and publish the results.

The Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission is prepared for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface.NASA/Kim Shiflett A NASA-developed technology that recently proved its capabilities in the harsh environment of space will soon head back to the Moon to search for gases trapped under the lunar surface thanks to a new Cooperative Research and Development Agreement between NASA and commercial company Magna Petra Corp.
The Mass Spectrometer Observing Lunar Operations (MSOLO) successfully demonstrated the full range of its hardware in lunar conditions during the Intuitive Machines 2 mission earlier this year. Under the new agreement, a second MSOLO, mounted on a commercial rover, will launch to the Moon no earlier than 2026. Once on the lunar surface, it will measure low molecular weight volatiles in hopes of inferring the presence of rare isotopes, such as Helium-3, which is theorized to exist, trapped in the regolith, or lunar dust, of the Moon.
“This new mission opportunity will help us determine what volatiles are present in the lunar surface, while also providing scientific insight for Magna Petra’s goals,” said Roberto Aguilar Ayala, research physicist at NASA’s Kennedy Space Center in Florida. “Learning more about the lunar volatiles and their isotopes supports NASA’s goal of sustaining long-term human space exploration. We will need to extract resources locally to enhance the capabilities of our astronauts to further exploration opportunities on the lunar surface.”
The MSOLO instrument will be integrated on a commercial rover, selected by Magna Petra. The rover will allow MSOLO to gather the data needed for researchers to understand which low-molecular weight gases reside within the Moon’s surface.
NASA will work with the partner to integrate MSOLO so that it will function properly with the rover, and the partner will analyze and share data in real time with NASA to understand the location of these volatiles on the Moon and their ability to be extracted in the future.
Magna Petra hopes to understand the presence of Helium-3 isotope within the Moon’s surface, with the ultimate goal of collecting it and bringing it back to Earth for use in a variety of industries, including energy production through nuclear fusion, quantum computing, health care, and specialized laboratory equipment.
The MSOLO instrument began as a commercial off-the-shelf mass spectrometer designed to analyze volatiles used in the manufacturing of semi-conductors, which helped keep NASA’s development costs down. NASA modified the device to withstand the rigors of spaceflight and the Moon’s harsh conditions. On its first journey to the Moon, MSOLO was part of the Polar Resources Ice Mining Experiment 1.
Signed on April 2, the reimbursable agreement is the first of its kind established at NASA Kennedy. Under the agreement, Magna Petra will reimburse NASA for costs such as supporting MSOLO integration and testing with the rover, pre-mission preparation and mission operations of the instruments, and expertise in system engineering, avionics, and software.
“This innovative agreement promises to provide valuable data to both partners,” said Jonathan Baker, chief of Spaceport Development at NASA Kennedy. “This approach demonstrates NASA’s commitment to finding unique ways to work with commercial industry to help advance technology in a fiscally responsible way and enabling innovation for the benefit of humankind.”
Throughout the mission, NASA will retain ownership of MSOLO. Once the mission is complete, the instrument will no longer have access to power and communications and will remain on the surface of the Moon. The valuable data gathered during the mission will be submitted to the Planetary Data System for public dissemination.

4 Min Read NASA Marshall Fires Up Hybrid Rocket Motor to Prep for Moon Landings
NASA’s Artemis campaign will use human landing systems, provided by SpaceX and Blue Origin, to safely transport crew to and from the surface of the Moon, in preparation for future crewed missions to Mars. As the landers touch down and lift off from the Moon, rocket exhaust plumes will affect the top layer of lunar “soil,” called regolith, on the Moon. When the lander’s engines ignite to decelerate prior to touchdown, they could create craters and instability in the area under the lander and send regolith particles flying at high speeds in various directions.
To better understand the physics behind the interaction of exhaust from the commercial human landing systems and the Moon’s surface, engineers and scientists at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently test-fired a 14-inch hybrid rocket motor more than 30 times. The 3D-printed hybrid rocket motor, developed at Utah State University in Logan, Utah, ignites both solid fuel and a stream of gaseous oxygen to create a powerful stream of rocket exhaust.
“Artemis builds on what we learned from the Apollo missions to the Moon. NASA still has more to learn more about how the regolith and surface will be affected when a spacecraft much larger than the Apollo lunar excursion module lands, whether it’s on the Moon for Artemis or Mars for future missions,” said Manish Mehta, Human Landing System Plume & Aero Environments discipline lead engineer. “Firing a hybrid rocket motor into a simulated lunar regolith field in a vacuum chamber hasn’t been achieved in decades. NASA will be able to take the data from the test and scale it up to correspond to flight conditions to help us better understand the physics, and anchor our data models, and ultimately make landing on the Moon safer for Artemis astronauts.”
Fast Facts
Over billions of years, asteroid and micrometeoroid impacts have ground up the surface of the Moon into fragments ranging from huge boulders to powder, called regolith. Regolith can be made of different minerals based on its location on the Moon. The varying mineral compositions mean regolith in certain locations could be denser and better able to support structures like landers. Of the 30 test fires performed in NASA Marshall’s Component Development Area, 28 were conducted under vacuum conditions and two were conducted under ambient pressure. The testing at Marshall ensures the motor will reliably ignite during plume-surface interaction testing in the 60-ft. vacuum sphere at NASA’s Langley Research Center in Hampton, Virginia, later this year.
Once the testing at NASA Marshall is complete, the motor will be shipped to NASA Langley. Test teams at NASA Langley will fire the hybrid motor again but this time into simulated lunar regolith, called Black Point-1, in the 60-foot vacuum sphere. Firing the motor from various heights, engineers will measure the size and shape of craters the rocket exhaust creates as well as the speed and direction the simulated lunar regolith particles travel when the rocket motor exhaust hits them.
“We’re bringing back the capability to characterize the effects of rocket engines interacting with the lunar surface through ground testing in a large vacuum chamber — last done in this facility for the Apollo and Viking programs. The landers going to the Moon through Artemis are much larger and more powerful, so we need new data to understand the complex physics of landing and ascent,” said Ashley Korzun, principal investigator for the plume-surface interaction tests at NASA Langley. “We’ll use the hybrid motor in the second phase of testing to capture data with conditions closely simulating those from a real rocket engine. Our research will reduce risk to the crew, lander, payloads, and surface assets.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
An astronaut glove designed for International Space Station spacewalks is prepped for testing in a chamber called CITADEL at NASA JPL. Conducted at temperatures as frigid as those Artemis III astronauts will see on the lunar South Pole, the testing supports next-generation spacesuit development.NASA/JPL-Caltech Engineers with NASA Johnson and the NASA Engineering and Safety Center ready an astronaut glove for insertion into the main CITADEL chamber at JPL. The team tested the glove in vacuum at minus 352 degrees Fahrenheit (minus 213 degrees Celsius).NASA/JPL-Caltech A JPL facility built to support potential robotic spacecraft missions to frozen ocean worlds helps engineers develop safety tests for next-generation spacesuits.
When NASA astronauts return to the Moon under the Artemis campaign and eventually venture farther into the solar system, they will encounter conditions harsher than any humans have experienced before. Ensuring next-generation spacesuits protect astronauts requires new varieties of tests, and a one-of-a-kind chamber called CITADEL (Cryogenic Ice Testing, Acquisition Development, and Excavation Laboratory) at NASA’s Jet Propulsion Laboratory in Southern California is helping.
Built to prepare potential robotic explorers for the frosty, low-pressure conditions on ocean worlds like Jupiter’s frozen moon Europa, CITADEL also can evaluate how spacesuit gloves and boots hold up in extraordinary cold. Spearheaded by the NASA Engineering and Safety Center, a glove testing campaign in CITADEL ran from October 2023 to March 2024. Boot testing, initiated by the Extravehicular Activity and Human Surface Mobility Program at NASA’s Johnson Space Center in Houston, took place from October 2024 to January 2025.
An astronaut boot — part of a NASA lunar spacesuit prototype, the xEMU — is readied for testing in JPL’s CITADEL. A thick aluminum plate stands in for the cold surface of the lunar South Pole, where Artemis III astronauts will confront conditions more extreme than any humans have yet experienced.NASA/JPL-Caltech In coming months, the team will adapt CITADEL to test spacesuit elbow joints to evaluate suit fabrics for longevity on the Moon. They’ll incorporate abrasion testing and introduce a simulant for lunar regolith, the loose material that makes up the Moon’s surface, into the chamber for the first time.
“We’ve built space robots at JPL that have gone across the solar system and beyond,” said Danny Green, a mechanical engineer who led the boot testing for JPL. “It’s pretty special to also use our facilities in support of returning astronauts to the Moon.”
Astronauts on the Artemis III mission will explore the Moon’s South Pole, a region of much greater extremes than the equatorial landing sites visited by Apollo-era missions. They’ll spend up to two hours at a time inside craters that may contain ice deposits potentially important to sustaining long-term human presence on the Moon. Called permanently shadowed regions, these intriguing features rank among the coldest locations in the solar system, reaching as low as minus 414 degrees Fahrenheit (minus 248 degrees Celsius). The CITADEL chamber gets close to those temperatures.
Engineers from JPL and NASA Johnson set up a test of the xEMU boot inside CITADEL. Built to prepare potential robotic explorers for conditions on ocean worlds like Jupiter’s moon Europa, the chamber offers unique capabilities that have made it useful for testing spacesuit parts.NASA/JPL-Caltech “We want to understand what the risk is to astronauts going into permanently shadowed regions, and gloves and boots are key because they make prolonged contact with cold surfaces and tools,” said Zach Fester, an engineer with the Advanced Suit Team at NASA Johnson and the technical lead for the boot testing.
Keeping Cool
Housed in the same building as JPL’s historic 10-Foot Space Simulator, the CITADEL chamber uses compressed helium to get as low as minus 370 F (minus 223 C) — lower than most cryogenic facilities, which largely rely on liquid nitrogen. At 4 feet (1.2 meters) tall and 5 feet (1.5 meters) in diameter, the chamber is big enough for a person to climb inside.
An engineer collects simulated lunar samples while wearing the Axiom Extravehicular Mobility Unit spacesuit during testing at NASA Johnson in late 2023. Recent testing of existing NASA spacesuit designs in JPL’s CITADEL chamber will ultimately support de-velopment of next-generation suits being built by Axiom Space.Axiom Space More important, it features four load locks, drawer-like chambers through which test materials are inserted into the main chamber while maintaining a chilled vacuum state. The chamber can take several days to reach test conditions, and opening it to insert new test materials starts the process all over again. The load locks allowed engineers to make quick adjustments during boot and glove tests.
Cryocoolers chill the chamber, and aluminum blocks inside can simulate tools astronauts might grab or the cold lunar surface on which they’d walk. The chamber also features a robotic arm to interact with test materials, plus multiple visible-light and infrared cameras to record operations.
Testing Extremities
The gloves tested in the chamber are the sixth version of a glove NASA began using in the 1980s, part of a spacesuit design called the Extravehicular Mobility Unit. Optimized for spacewalks at the International Space Station, the suit is so intricate it’s essentially a personal spacecraft. Testing in CITADEL at minus 352 F (minus 213 C) showed the legacy glove would not meet thermal requirements in the more challenging environment of the lunar South Pole. Results haven’t yet been fully analyzed from boot testing, which used a lunar surface suit prototype called the Exploration Extravehicular Mobility Unit. NASA’s reference design of an advanced suit architecture, this spacesuit features enhanced fit, mobility, and safety.
In addition to spotting vulnerabilities with existing suits, the CITADEL experiments will help NASA prepare criteria for standardized, repeatable, and inexpensive test methods for the next-generation lunar suit being built by Axiom Space — the Axiom Extravehicular Mobility Unit, which NASA astronauts will wear during the Artemis III mission.
“This test is looking to identify what the limits are: How long can that glove or boot be in that lunar environment?” said Shane McFarland, technology development lead for the Advanced Suit Team at NASA Johnson. “We want to quantify what our capability gap is for the current hardware so we can give that information to the Artemis suit vendor, and we also want to develop this unique test capability to assess future hardware designs.”
In the past, astronauts themselves have been part of thermal testing. For gloves, an astronaut inserted a gloved hand into a chilled “glove box,” grabbed a frigid object, and held it until their skin temperature dropped as low as 50 F (10 C). McFarland stressed that such human-in-the-loop testing remains essential to ensuring future spacesuit safety but doesn’t produce the consistent data the team is looking for with the CITADEL testing.
To obtain objective feedback, the CITADEL testing team used a custom-built manikin hand and foot. A system of fluid loops mimicked the flow of warm blood through the appendages, while dozens of temperature and heat flux sensors provided data from inside gloves and boots.
“By using CITADEL and modern manikin technology, we can test design iterations faster and at much lower cost than traditional human-in-the-loop testing,” said Morgan Abney, NASA technical fellow for Environmental Control and Life Support, who conceived the glove testing effort. “Now we can really push the envelope on next-generation suit designs and have confidence we understand the risks. We’re one step closer to landing astronauts back on the Moon.”
Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
