NASA funds GIMLI mission to search for a cave beneath a lunar pit

NASA selected a PSI-led proposal, GIMLI, to determine whether a large cave or lava tube extends underground from the Marius Hills pit on the Moon. The mission will use ground-penetrating radar, seismic sensors, a gravimeter and cameras delivered via the CLPS program, with Honeybee Robotics and the Norwegian Space Agency as partners.

• GIMLI is led by PSI and funded through NASA's PRISM program
• Instruments include ground-penetrating radar, seismic sensors, a gravimeter and cameras
• Honeybee Robotics will build much of the hardware; Norway will supply the radar
• A confirmed cave could shelter astronauts from radiation and temperature swings
