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.

Video: 00:03:06 The ExoMars Rosalind Franklin rover will drill deeper than any other mission has ever attempted on the Red Planet.
The third episode in the series shows how the rover will extract, collect and analyse martian samples in a high-fidelity simulation.
Rosalind Franklin will be the first rover to reach a depth of up to two metres deep below the surface, acquiring samples that have been protected from harsh fsurface radiation and extreme temperatures.
The drill system combines multiple precission mechanisms in an intricate automated sequence. It uses three extension rods that connect tor form a two-metre “drill string”.
As the rover drills, it will simultaneously investigate the borehole using infrared spectroscopy to study mineral composition.
The ExoMars Rosalind Franklin mission is part of Europe’s ambitious exploration journey to search for past and present signs of life on Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist’s concept depicts NASA’s Europa Clipper as it flies by Mars, using the planet’s gravitational force to alter the spacecraft’s path on its way to the Jupiter system. NASA/JPL-Caltech The orbiter bound for Jupiter’s moon Europa will investigate whether the moon is habitable, but it first will get the help of Mars’ gravitational force to get to deep space.
On March 1, NASA’s Europa Clipper will streak just 550 miles (884 kilometers) above the surface of Mars for what’s known as a gravity assist — a maneuver to bend the spacecraft’s trajectory and position it for a critical leg of its long voyage to the Jupiter system. The close flyby offers a bonus opportunity for mission scientists, who will test their radar instrument and thermal imager.
Europa Clipper will be closest to the Red Planet at 12:57 p.m. EST, approaching it at about 15.2 miles per second (24.5 kilometers per second) relative to the Sun. For about 12 hours prior and 12 hours after that time, the spacecraft will use the gravitational pull of Mars to pump the brakes and reshape its orbit around the Sun. As the orbiter leaves Mars behind, it will be traveling at a speed of about 14 miles per second (22.5 kilometers per second).
The flyby sets up Europa Clipper for its second gravity assist — a close encounter with Earth in December 2026 that will act as a slingshot and give the spacecraft a velocity boost. After that, it’s a straightforward trek to the outer solar system; the probe is set to arrive at Jupiter’s orbit in April 2030.
“We come in very fast, and the gravity from Mars acts on the spacecraft to bend its path,” said Brett Smith, a mission systems engineer at NASA’s Jet Propulsion Laboratory in Southern California. “Meanwhile, we’re exchanging a small amount of energy with the planet, so we leave on a path that will bring us back past Earth.”
This animation depicts NASA’s Europa Clipper as it flies by the Red Planet. The spacecraft will use the planet’s gravity to bend its path slightly, setting up the next leg of its long journey to investigate Jupiter’s icy moon Europa. NASA/JPL-Caltech Harnessing Gravity
Europa Clipper launched from Kennedy Space Center in Florida on Oct. 14, 2024, via a SpaceX Falcon Heavy, embarking on a 1.8-billion-mile (2.9-billion-kilometer) trip to Jupiter, which is five times farther from the Sun than Earth is. Without the assists from Mars in 2025 and from Earth in 2026, the 12,750-pound (6,000-kilogram) spacecraft would require additional propellant, which adds weight and cost, or it would take much longer to get to Jupiter.
Gravity assists are baked into NASA’s mission planning, as engineers figure out early on how to make the most of the momentum in our solar system. Famously, the Voyager 1 and Voyager 2 spacecraft, which launched in 1977, took advantage of a once-in-a-lifetime planetary lineup to fly by the gas giants, harnessing their gravity and capturing data about them.
While navigators at JPL, which manages Europa Clipper and Voyager, have been designing flight paths and using gravity assists for decades, the process of calculating a spacecraft’s trajectory in relation to planets that are constantly on the move is never simple.
“It’s like a game of billiards around the solar system, flying by a couple of planets at just the right angle and timing to build up the energy we need to get to Jupiter and Europa,” said JPL’s Ben Bradley, Europa Clipper mission planner. “Everything has to line up — the geometry of the solar system has to be just right to pull it off.”
About 4½ months after its launch, NASA’s Europa Clipper is set to perform a gravity as-sist maneuver as it flies by Mars on March 1. Next year the spacecraft will swing back by Earth for a final gravity assist before NASA/JPL-Caltech Refining the Path
Navigators sent the spacecraft on an initial trajectory that left some buffer around Mars so that if anything were to go wrong in the weeks after launch, Europa Clipper wouldn’t risk impacting the planet. Then the team used the spacecraft’s engines to veer closer to Mars’ orbit in what are called trajectory correction maneuvers, or TCMs.
Mission controllers have performed three TCMs to set the stage for the Mars gravity assist — in early November, late January, and on Feb. 14. They will conduct another TCM about 15 days after the Mars flyby to ensure the spacecraft is on track and are likely to conduct additional ones — upwards of 200 — throughout the mission, which is set to last until 2034.
Opportunity for Science
While navigators are relying on the gravity assist for fuel efficiency and to keep the spacecraft on their planned path, scientists are looking forward to the event to take advantage of the close proximity to the Red Planet and test two of the mission’s science instruments.
About a day prior to the closest approach, the mission will calibrate the thermal imager, resulting in a multicolored image of Mars in the months following as the data is returned and scientists process the data. And near closest approach, they’ll have the radar instrument perform a test of its operations — the first time all its components will be tested together. The radar antennas are so massive, and the wavelengths they produce so long that it wasn’t possible for engineers to test them on Earth before launch.
More About Europa Clipper
Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, managed the launch service for the Europa Clipper spacecraft.
