NASA has selected the Planetary Science Institute (PSI) to explore the potential existence of a large underground cave beneath a pit on the Moon, specifically the Marius Hill Pit (MHP). This initiative aims to provide natural protection for astronauts against radiation and extreme temperature fluctuations.
The project, named the Geophysical Instruments for Marius Lunar pit Investigation (GIMLI), will be funded through NASA’s PRISM program, which uses commercial partners for lunar payload delivery. PSI will collaborate with Honeybee Robotics to develop instruments for a lander and rover, with additional support from the Norwegian Space Agency.
GIMLI’s scientific team, led by PSI’s Than Putzig, aims to investigate the Moon’s subsurface geology directly, utilizing ground-penetrating radar, seismic sensors, and a gravimeter. This comprehensive approach may uncover underground lava tubes, enhancing our understanding of the Moon’s volcanic history.
Even if no caves are found, the investigation will still yield valuable information regarding the formation of MHP and the region’s geological history. The mission leverages insights from geology and volcanism on Earth to enhance knowledge of lunar processes. The collaboration includes researchers from multiple institutions, underscoring a united effort to better understand the Moon’s past.
