NASA Backs Mission to Probe Mysterious Lunar Pit
NASA is supporting a project to study a large hole on the Moon.
The hole is called Marius Hills Pit.
Scientists want to find out whether it opens into a long cave made by ancient lava.
They plan to use radar, sensors that detect shaking, a gravity-measuring instrument, and cameras.
These tools will help them examine both the pit and the ground below it.
The Moon’s old lava caves might teach scientists about its past.
If some caves are still intact, they could also offer shelter for people living on the Moon.
NASA has backed GIMLI, a project led by the Planetary Science Institute through its PRISM programme.
The mission will investigate Marius Hills Pit, about 34 meters deep and 65 by 90 meters across.
Researchers do not yet know whether the pit connects to an extensive underground lava tube.
GIMLI will use ground-penetrating radar, seismic sensors, a gravimeter, and cameras to study the pit and its surroundings.
The findings could reveal lunar volcanic history and assess whether intact lava tubes could provide natural shelter for future human outposts.
- Who
- The Planetary Science Institute is leading GIMLI with NASA and Honeybee Robotics as partners.
- What
- The project will investigate whether Marius Hills Pit connects to an underground lava tube.
- Where
- Marius Hills Pit, in an ancient volcanic region on the Moon's nearside.
- When
- Why
- To investigate the Moon's subsurface and volcanic history, and explore whether intact lava tubes could provide natural shelter.
Potential lava tube
Unconfirmed underground extension
Whether the pit opens into a cave
Potential lava tube
The mission is designed to investigate the anticipated possibility that a lava tube extends from Marius Hills Pit.
Unconfirmed underground extension
The existence of the pit is confirmed by satellite imagery, but available data do not prove that it connects to a long underground cave system.
Potential use of intact tubes
Potential lava tube
Intact lava tubes could provide structurally sound natural shelters for long-term human outposts.
Unconfirmed underground extension
Their existence and condition at this site have not yet been established; GIMLI aims to search for an underground void.
