Three new science investigations added to NASA Moon Base

NASA has selected three new scientific investigations and their payload suites to help pave the way for building humanity’s first lunar outpost, Moon Base.

The suite of science instruments and technologies was selected through NASA’s Payloads and Research Investigations on the Surface of the Moon (PRISM) program and will fly to the lunar surface using the CLPS (Commercial Lunar Payload Services) initiative as part of the agency’s Moon Base Program.

The payloads will help researchers understand lunar resources, map natural shelters, and assess environmental hazards, laying the foundational groundwork for a safe and sustained human presence under the agency’s Artemis and Moon Base programs.

“NASA Science is building the ultimate interplanetary survival guide to ensure that science goes first to the lunar surface to provide our future astronaut crews with the vital information, resources, and safety precautions needed ahead of time to survive the night on the Moon,” said Nicky Fox, associate administrator, Science Mission Directorate, at NASA Headquarters in Washington. “These PRISM selections will directly help NASA minimise risks to our astronauts while maximising our agency goals as we set up humanity’s first lunar outpost in preparation for sending the first astronauts to Mars.”

The three payload suites are:

Lunar Environment Monitoring Station – South Pole (LEMS-SP):

• The autonomous LEMS-SP instrument suite will serve as a long-term environmental and hazard monitoring station. The instrument will be designed to help build a picture of the lunar environment by monitoring falling micrometeoroids and tracking the abundance of volatiles, or materials that can easily shift into gas, that drift into the Moon’s thin outer layer of gases. Using a short‑period seismometer to detect seismic events, the instrument could deliver the critical hazard assessments needed to ensure the physical safety of Moon Base hardware.

Principal Investigator: Dr. Mehdi Benna, University of Maryland, Baltimore County
 Geophysical Investigation for Mapping Lunar Interior (GIMLI): 

• The GIMLI payload will be deployed at the Marius Hills Pit on the lunar surface to hunt for subterranean lava tubes and aid in our understanding of fundamental lunar volcanic processes. The payload will scan beneath the Moon’s surface to see whether the Marius Hills Pit leads into a large underground lava tube. If it does, these natural underground spaces could offer future astronauts ready‑made protection from extreme temperatures and harmful radiation — important groundwork for safe, long‑term living on the Moon. Confirming these void spaces now could shift future habitat planning, offering natural, ready-made shelters that provide crucial thermal stability and shielding from deadly ionising radiation and micrometeoroid bombardment.

Principal Investigator: Dr. Nathaniel Putzig, Planetary Science Institute
Depth Imager with Spectral and Color Optics (DISCO): 

• The DISCO payload will provide the first direct, on-the-ground measurements of ice hidden in lunar micro-cold traps and also will lay the groundwork for lunar resource utilisation and surface operations. The payload will study how the lunar surface behaves, from how rocket exhaust disturbs the ground to how stable it is for mobility, while also pinpointing where ice exists and how much of it is there. Together, this information will help NASA design safe surface operations and develop the technologies needed to turn ice into a usable resource for the future Moon Base.

“Expanding the frontier of lunar exploration”

“Each new PRISM selection strengthens our ability to deliver ambitious, transformative science to the lunar surface,” said Brad Bailey, director of the Exploration Science Strategy Integration Office in NASA’s Science Mission Directorate. “These investigations exemplify how Artemis and Moon Base are expanding the frontier of lunar exploration, advancing innovative technologies, deepening our understanding of the Moon’s environment, and paving the way for future astronaut missions.”

NASA is increasing its cadence of lunar missions to build a Moon Base, delivering science investigations and technology payloads that contribute to American scientific preeminence, strengthen a sustained presence on the Moon, and advance future human exploration.

NASA’s CLPS initiative supports the Moon Base Program, as the agency works with American companies to deliver scientific, exploration, and technology payloads to the Moon’s surface and orbit.
