Lunar regolith sample collected by China's Chang'e 5 mission displayed at Airshow China 2021. On 16 December 2020, China's Chang'e 5 mission returned to Earth with about 2 kilograms of rock and dirt it picked up from the Moon. It is the first lunar regolith sample to return to Earth since 1976.
The Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) is designed to measure heat flow from the interior of the Moon. The probe will attempt to drill 2.13 to 3.05 meters (7 to 10 ft) into the lunar regolith to investigate the Moon's thermal properties at different depths.
Subnautica is a 2018 action-adventure horror survival game developed and published by Unknown Worlds Entertainment. The player controls Ryley Robinson, a survivor of a spaceship crash on an alien oceanic planet, which they are free to explore.
The term lunar soil is often used interchangeably with "lunar regolith" but typically refers to the finer fraction of regolith, that which is composed of grains one centimetre in diameter or less. Some have argued that the term " soil " is not correct in reference to the Moon because soil is defined as having organic content, whereas the Moon ...
The thickness of the lunar regolith varies between 2 meters (6.6 ft) beneath the younger maria, to up to 20 meters (66 ft) beneath the oldest surfaces of the lunar highlands. The regolith is predominantly composed of materials found in the region, but also contains traces of materials ejected by distant impact craters.
Building the lunar base inside a deep crater would provide at least partial shielding against radiation and micrometeoroids. Artificial magnetic fields have been proposed [ 61 ] [ 62 ] as a means to provide radiation shielding for long range deep space crewed missions, and it might be possible to use similar technology on a lunar habitat.
The Lunar Prospector probe, launched in 1998, employed a neutron spectrometer to measure the amount of hydrogen in the lunar regolith near the polar regions. [32] It was able to determine hydrogen abundance and location to within 50 parts per million and detected enhanced hydrogen concentrations at the lunar north and south poles.
In the particular case of the Moon, this is more often known as lunar gardening. Planetary bodies lacking an atmosphere will generally also lack any erosional processes, with the possible exception of volcanism , and as a result impact debris accumulates at the object's surface as a rough "soil," commonly referred to as regolith .
