A SpaceX Falcon 9 rocket stands vertical on Tuesday, Feb. 25, 2025, at Launch Complex 39A at NASA’s Kennedy Space Center ahead of Intuitive Machines’ IM-2 mission as part of the agency’s Commercial Lunar Payload Services initiative and Artemis campaign. SpaceX Sending instruments to the Moon supports a growing lunar economy on and off Earth, and the next flight of NASA science and technology is only days away. NASA’s CLPS (Commercial Lunar Payload Services) initiative is a lunar delivery service that sends NASA science and technology instruments to various geographic locations on the Moon using American companies. These rapid, cost-effective commercial lunar missions at a cadence of about two per year improve our understanding of the lunar environment in advance of future crewed missions to the Moon as part of the agency’s broader Artemis campaign.
Of the 11 active CLPS contracts, there have been three CLPS launches to date: Astrobotic’s Peregrine Mission One, which collected data in transit but experienced an anomaly that prevented it from landing on the Moon; Intuitive Machines’ IM-1 mission, which landed, tipped over, and operated on the lunar surface; and Firefly Aerospace’s Blue Ghost Mission One that is currently enroute and scheduled to land in early March 2025. The CLPS contract awards cover end-to-end commercial payload delivery services, including payload integration, launch from Earth, landing on the surface of the Moon, and mission operations.
NASA’s fourth CLPS flight is from Intuitive Machines with their IM-2 mission. The IM-2 mission is carrying NASA science and technology instruments to Mons Mouton, a lunar plateau just outside of 5 degrees of the South Pole of the Moon, closer to the pole than any preceding lunar mission.
Scheduled to launch no earlier than Wednesday and land approximately eight days later, Intuitive Machines’ Nova-C lander, named Athena, will carry three NASA instruments to the lunar South Pole region – the Polar Resources Ice Mining Experiment-1 (PRIME-1) suite and the Laser Retroreflector Array (LRA).
The PRIME-1 suite consists of two instruments, the TRIDENT drill (The Regolith Ice Drill for Exploring New Terrain) and MSolo (Mass Spectrometer observing lunar operations), which will work together to extricate lunar soil samples, known as regolith, from the subsurface and analyze their composition to further understand the lunar environment and gain insight on potential resources that can be extracted for future examination.
The meter-long TRIDENT drill is designed to extract lunar regolith, up to about three feet below the surface. It will also measure soil temperature at varying depths below the surface, which will help to verify existing lunar thermal models that are used for ice stability calculations and resource mapping. By drilling into the lunar regolith, information is gathered to help answer questions about the lunar regolith geotechnical properties, such as soil strength, both at the surface and in the subsurface that will help inform Artemis infrastructure objectives. The data will be beneficial when designing future systems for on-site resource utilization that will use local resources to create everything from landing pads to rocket fuel. The lead development organization for TRIDENT is Honeybee Robotics, a Blue Origin Company.
The MSOLO instrument is a mass spectrometer capable of identifying and quantifying volatiles (or gasses that easily evaporate) found at or beneath the lunar surface, including– if it’s present in the regolith within the drill’s reach – water and oxygen, brought to the surface by the TRIDENT drill. This instrument can also detect any gases that emanate from the lander, drilling process, and other payloads conducting operations on the surface. Using MSolo to study the volatile gases found on the Moon can help us understand how the lander’s presence might alter the local environment. The lead development organization is INFICON of Syracuse, New York, in partnership with NASA’s Kennedy Space Center in Florida.
NASA’s LRA is a collection of eight retroreflectors that enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The LRA instrument is passive, meaning it does not power on. It will function as a permanent location marker on the Moon for decades to come, similar to its predecessors. The lead development organization is NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
In addition to the CLPS instruments, two technology demonstrations aboard IM-2 were developed through NASA’s Tipping Point opportunity. These are collaborations with the agency’s Space Technology Mission Directorate and industry that support development of commercial space capabilities and benefit future NASA missions.
Intuitive Machines developed a small hopping robot, Grace, named after Grace Hopper, computer scientist and mathematician. Grace will deploy as a secondary payload from the lander and enable high-resolution imaging and science surveying of the lunar surface, including permanently shadowed craters around the landing site. Grace is designed to bypass obstacles such as steep inclines, boulders, and craters to cover a lot of terrain while moving quickly, which is a valuable capability to support future missions on the Moon and other planets, including Mars.
Nokia will test a Lunar Surface Communications System that employs the same cellular technology here on Earth. Reconceptualized by Nokia Bell Labs to meet the unique requirements of a lunar mission, this tipping point technology aims to demonstrate proximity communications between the lander, a Lunar Outpost rover, and the hopper.
Launching as a rideshare alongside the IM-2 mission, NASA’s Lunar Trailblazer spacecraft also will begin its journey to lunar orbit where it will map the distribution of water – and other forms of water – on the Moon.
Future CLPS flights will continue to send payloads to the near side, far side, and South Pole regions of the Moon where investigations and exploration are informed by each area’s unique characteristics. With a pool of 13 American companies under CLPS, including a portfolio of 11 lunar deliveries by five vendors sending more than 50 individual science and technology instruments to lunar orbit and the surface of the Moon, NASA continues to advance long-term exploration of the Moon, and beyond to Mars.

Sols 4461-4463: Salty Salton Sea?
NASA’s Mars rover Curiosity acquired this image showing its Alpha Particle X-Ray Spectrometer (APXS), a spectrometer that measures the abundance of chemical elements in rocks and soils, on the “Chumash Trail” target in its workspace. Note the butte in the background. The rover used its Front Hazard Avoidance Camera (Front Hazcam) to capture the image on Feb. 19, 2025 — sol 4458, or Martian day 4,458 of the Mars Science Laboratory mission — at 21:03:48 UTC. NASA/JPL-Caltech Earth planning date: Friday, Feb. 21, 2025
Since first encountering the sulfate-bearing unit around Sol 3540, we have detected minerals and elemental concentrations consistent with the presence of various salts and a general drying out of Mars climate (read ”NASA’s Curiosity Mars Rover Reaches Long-Awaited Salty Region”). Salton Sea in California is a saline lake, meaning it has high concentrations of salty minerals formed as a result of evaporation processes dominating over input of fresh water. As such, we thought it would be a fitting name for one of our rock targets to be analyzed by the APXS and MAHLI instruments in this weekend plan. We have observed a variety of different textures and colors associated with the sulfate-bearing unit. The target “Salton Sea” is an example of one such texture — a dark-toned, relatively smooth, platy layer. Will the chemistry indicate the presence of salty minerals, some of which may be the same as those found at Salton Sea? Other rock targets to be analyzed in this busy weekend plan include “Wellman Divide,” another APXS and MAHLI target on a thicker, dark-toned, rougher textured layer, and “Goodykoontz” and “Paseo del Mar,” both ChemCam LIBS targets, on a nodule and a dark, platy layer, respectively.
We also continue to document the layers of rock exposed within several buttes and mesas around us (“Dragon Tooth” and “Texoli” buttes, and “Gould Mesa”) with CCAM RMI and Mastcam imaging. Curiosity will hopefully climb though equivalent layers as we continue our ascent of Mount Sharp, so these images can help with interpretation when we finally encounter them on the ground. Mastcam will also image a trough in the sand surrounding one of the bedrock blocks — a feature that has been observed relatively frequently lately.
The atmospheric scientists also have an action-packed plan with coordinated APXS atmospheric and ChemCam passive-sky observations to measure argon and oxygen, respectively, as well as standard activities. These observations help to track changes in seasonal atmospheric flow from equatorial to polar regions on Mars. Standard atmospheric monitoring activities included in the plan are: Navcam dust devil movies (x2), suprahorizon movies (x2), a zenith movie, line of sight observations (x2), and a cloud altitude observation, as well as Mastcam tau observations (x2).
After a planned drive of about 49 meters (about 161 feet) on the second sol of this three-sol weekend plan, the MARDI camera will take an image of the terrain beneath the rover. The plan is rounded out with standard REMS, DAN and RAD activities.

For more than a decade, Tristan McKnight has been a driving force behind some of NASA’s most iconic events, orchestrating the behind-the-scenes magic that brings each historic moment to life while sharing the agency’s advancements with the public.
As a multimedia producer on the audiovisual team at Johnson Space Center in Houston, McKnight produces and directs live broadcasts and manages event planning, coordination, and execution. From overseeing resources, mitigating risks, and communicating with stakeholders, he ensures every detail aligns seamlessly.
Official portrait of Tristan McKnight.NASA/Josh Valcarcel McKnight has played an integral role in the audiovisual team’s coverage of major events including the Artemis II crew announcement, where NASA revealed the astronauts who will venture around the Moon and back, to Johnson’s 2023 Open House, which celebrated the agency’s 65th anniversary and the 25th anniversary of the International Space Station’s operations. These achievements highlight key milestones in human space exploration.
A standout achievement was contributing to the Dorothy Vaughan Center in Honor of the Women of Apollo naming ceremony, held on the eve of the 55th anniversary of the Apollo 11 Moon landing. The event honored the unsung heroes who made humanity’s first steps on the Moon possible.
The team’s dedication and passion are a testament to their commitment to sharing NASA’s legacy with the world.
“Not only have these events been impactful to Johnson, but they have also resonated across the entire agency,” McKnight said. “That is what I’m most proud of!”
Tristan McKnight at the 45th Annual Original Martin Luther King Jr. Day Parade in downtown Houston.NASA/James Blair One of McKnight’s most memorable events was the 2023 “Back in the Saddle,” an annual tradition designed to refocus Johnson’s workforce at the start of a new year and renew the center’s commitment to safety and mission excellence. McKnight recalled how the speaker transformed Johnson’s Teague Auditorium into a venue filled with drum kits, inspiring messages, and lighting displays. Each audience member, drumsticks in hand, participated in a lesson on teamwork and synchronization to create a metaphor for working in harmony toward a shared goal.
Like many high-achieving professionals. McKnight has faced moments of self-doubt. Then he realized that he is exactly where he is supposed to be. “As I settled into my role, I recognized that my contributions matter and simply being true to who I am adds value to the Johnson community,” he said.

One of McKnight’s most valuable lessons is recognizing that there is no one-size-fits-all solution, and each situation requires a thoughtful analysis.
McKnight understands the importance of the “check-and double-check,” a philosophy he considers crucial when working with technology. “Taking the extra time to do your due diligence, or even having someone else take a look, can make all the difference,” he said.
“The challenges I’ve faced helped me grow as a problem solver and taught me valuable lessons on resilience and adaptability in the workplace,” he said. McKnight approaches obstacles with a level head, focusing on effective solutions rather than dwelling on the problem.

Artistic rendering of Intuitive Machines’ Nova-C lander on the surface of the Moon.Credit: Intuitive Machines NASA’s Polar Resources Ice Mining Experiment-1 (PRIME-1) is preparing to explore the Moon’s subsurface and analyze where lunar resources may reside. 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.
