NASA selected three science payload suites for future lunar-surface missions through its PRISM program and CLPS delivery initiative. The instruments are designed to monitor environmental hazards, investigate a possible underground lava tube and measure ice and surface conditions; mission schedules and delivery dates were not specified in the release.
NASA has selected three new lunar science investigations to study environmental hazards, possible natural shelters and ice on the Moon, gathering information the agency says will help prepare for a sustained human presence there. The payload suites were chosen through NASA’s PRISM program and are expected to reach the surface through the Commercial Lunar Payload Services (CLPS) initiative, as part of the agency’s Moon Base Program.
The selected investigations address different questions that could affect where and how future crews operate. The Lunar Environment Monitoring Station – South Pole (LEMS-SP) is designed as an autonomous, long-term monitoring station. It is intended to track micrometeoroid impacts, measure volatile materials entering the Moon’s thin outer atmosphere and use a short-period seismometer to detect seismic activity. NASA says the observations could help assess hazards to lunar equipment. Its principal investigator is Mehdi Benna of the University of Maryland, Baltimore County.
Geophysical Investigation for Mapping Lunar Interior (GIMLI) is planned for deployment at the Marius Hills Pit. It will scan below the surface to investigate whether the pit connects to a large lava tube and to study lunar volcanic processes. NASA says such underground spaces, if found and suitable, could offer shelter from temperature extremes, radiation and micrometeoroid impacts. The principal investigator is Nathaniel Putzig of the Planetary Science Institute.
The third selection, Depth Imager with Spectral and Color Optics (DISCO), is intended to make direct surface measurements of ice in extremely cold lunar areas, while examining how the ground responds to rocket exhaust and how stable it is for movement. NASA says the results could inform surface operations and the development of ways to use lunar ice as a resource. Ariel Deutsch of NASA’s Ames Research Center is the principal investigator. The agency’s release did not give delivery dates, mission assignments or budgets for the three payloads.
Data for Safer Lunar Operations
The investigations target practical unknowns that would shape the design and operation of a long-term lunar outpost. Information about seismic activity, impacts and volatile materials could help planners evaluate environmental risks to crews and equipment. A better understanding of underground spaces could inform whether natural formations merit further consideration for shelter, while direct measurements of ice and surface behavior could help assess potential resources and landing or mobility conditions.
Those benefits remain prospective. The payloads are research instruments, not evidence that a lunar base is already built or that ice extraction or lava-tube habitation is ready for use. Their importance lies in collecting data before NASA makes decisions about future surface operations. NASA says the work is intended to support Artemis and Moon Base planning and contribute to later human exploration, including missions to Mars.

PRISM Payloads and CLPS Delivery
NASA selected the instruments under Payloads and Research Investigations on the Surface of the Moon (PRISM), a program for scientific investigations on the lunar surface. The agency says it will use CLPS to deliver the selected payloads. CLPS works with American companies to transport science, exploration and technology payloads to the Moon’s surface and orbit.
NASA describes the selections as part of a broader effort to increase the cadence of lunar missions and build knowledge for its Moon Base Program. The agency links that work to Artemis, its human lunar exploration program. In the announcement, Nicky Fox, associate administrator of NASA’s Science Mission Directorate, said the investigations would provide information and safety data before crews arrive. Brad Bailey, who directs the Exploration Science Strategy Integration Office, said the selections would expand lunar science and support future astronaut missions. Those are NASA’s stated objectives; the release does not establish a timetable for a base or for crewed use of the results.
“These PRISM selections will directly help NASA minimize risks to our astronauts while maximizing our agency goals as we set up humanity’s first lunar outpost in preparation for sending the first astronauts to Mars.”

Mission Dates and Findings Pending
The NASA announcement does not identify launch or landing dates, CLPS delivery providers, mission schedules or costs for the three payload suites. It also does not say when the investigations will return results. Those details matter because the scientific aims depend on instruments reaching their intended locations and operating successfully on the lunar surface.
Several central outcomes are unknown by design. GIMLI is meant to determine whether the Marius Hills Pit connects to a large lava tube; the release does not say that such a connection has been confirmed. DISCO is intended to locate and measure ice in micro-cold traps, but the announcement provides no findings about how much ice exists or whether it could be extracted for use. LEMS-SP’s planned monitoring could assess hazards, but the release reports no measurements or conclusions from the instrument. NASA’s description of the potential benefits should be understood as goals, not completed results.

Awaiting Lunar Delivery Plans
The next concrete milestones will be NASA’s assignment of delivery missions and publication of schedules for the payloads. CLPS flights will be needed to put the instruments on the Moon, after which researchers can report observations from their target sites. NASA’s release did not specify when those announcements or flights are expected.
As mission plans develop, the key questions will be whether the instruments can operate as designed, what they find about lunar hazards and resources, and how the results affect planning for future surface activity. For now, the agency has selected the investigations and stated their objectives; the measurements and any resulting changes to Moon Base plans remain ahead.

Key Questions
What did NASA announce?
NASA selected three lunar science payload suites through PRISM: LEMS-SP, GIMLI and DISCO. They are intended to study lunar environmental hazards, a possible lava tube and ice and surface conditions.
Have the payloads been sent to the Moon?
The announcement says the payloads will fly through NASA’s CLPS initiative, but it does not provide launch or landing dates or identify delivery missions.
Has NASA confirmed a lava tube at Marius Hills Pit?
No. GIMLI is intended to investigate whether the pit connects to an underground lava tube. The NASA release reports no finding confirming one.
Will DISCO extract lunar ice?
The release describes DISCO as a measurement investigation, not an ice-extraction system. It is intended to locate and measure ice and study surface conditions that could inform future resource-use planning.
When will results be available?
NASA did not provide a timetable for delivery, operations or results. Those dates remain unannounced.
