Summary
NASA selected three payload suites to study lunar hazards, look for a possible lava tube at the Marius Hills Pit, and measure ice and surface conditions. The investigations are intended to support planning for future Moon operations.
NASA has selected three science payload suites for future lunar-surface missions, targeting environmental hazards, a possible underground lava tube, and ice and terrain conditions. The investigations were chosen through its Payloads and Research Investigations on the Surface of the Moon (PRISM) program and are intended to travel to the Moon through the Commercial Lunar Payload Services (CLPS) initiative as part of NASA’s Moon Base Program.
The work is aimed at gathering information that could help researchers plan safer surface operations and assess resources for a sustained human presence. One of the investigations will examine whether a lunar pit connects to a larger underground space; the announcement does not report a confirmed cave.
Three investigations for lunar operations
The Lunar Environment Monitoring Station – South Pole (LEMS-SP) is designed as an autonomous, long-term monitoring station. Its instruments would track falling micrometeoroids and the abundance of volatiles—materials that can readily become gas—in the Moon’s thin outer layer of gases. A short-period seismometer would detect seismic events. NASA says those observations could help assess hazards to Moon Base hardware.
Geophysical Instruments for Marius Lunar pit Investigation (GIMLI) will be deployed at the Marius Hills Pit. It is designed to scan beneath the surface to determine whether the pit leads into a large underground lava tube and to investigate lunar volcanic processes. The possibility matters for habitat planning: underground spaces could offer more stable temperatures and shielding from radiation and micrometeoroid impacts than the exposed surface. Whether the pit connects to such a tube is the question the investigation is intended to test.
The third payload, Depth Imager with Spectral and Color Optics (DISCO), is intended to make direct, on-the-ground measurements of ice in lunar micro-cold traps. These are extremely cold regions where ice may persist. NASA says DISCO will also examine how the surface responds to rocket exhaust and how stable it is for mobility, while locating ice and measuring its amount. Those findings could inform surface-operation designs and efforts to use lunar ice as a resource.
From lunar measurements to habitat planning
The investigations address different practical questions: what hazards equipment may face, whether natural underground shelter exists at a candidate site, and where ice and usable terrain may be found. Together, they could help turn observations of the lunar environment into engineering and resource-planning information for future missions.
NASA says the payloads will fly through CLPS, which works with American companies to deliver science, exploration and technology payloads to the Moon’s surface and orbit. The announcement describes the investigations as groundwork for a safe, sustained presence under the Artemis and Moon Base programs. Their planned measurements are preparatory science; they are not themselves construction of a lunar habitat.
