The Moon is the only natural satellite of Earth. It has caves which may serve as refuge from cosmic radiation and other damaging effects from space. It has recently become apparent, by collision of L-cross into the Moon’s South Pole, that it also has plenty of water in forms of ice. The discovery of spectral shift which identified water, led scientist renew their enthusiasm for a lunar outpost. Analysis of water on a mostly pristine environment might have recorded events of our solar system shortly after the Moon’s formation. A notable atmosphere must be created before terraforming can begin. However, the Moon is too small to hold an atmosphere so putting a global giant air dome or replenishing the atmosphere as needed.
