What is the Moon made of?
The Moon is a rocky satellite, and is made of similar material to the Earth. It has an outer layer, or mantle, of rock, and a core that is probably made up mostly of iron. Unlike the Earth’s liquid mantle, the interior of the Moon is cool and solid. There is little or no volcanic activity on the Moon. However, while it was cooling early in its life, floods or streams of lava ran out across the Moon’s surface.
Dead planet!
Living things need air and water to stay alive, and neither of these is available on the Moon. The atmosphere of the Moon is a higher vacuum than can be created in most scientific laboratories. The Moon also suffers extreme temperature swings between the lunar day and night. Lunar conditions have been re-created in laboratories on the Earth, but no form of terrestrial life has been able to survive them. There is some water on the Moon’s surface, in the form of frost that can be found in shadowed craters near the Moon’s poles.
