Lunar habitation is any human social and material structure and activity on the Moon making human habitation on the Moon. Therefore, it is more than the particular surface space habitats and more specific than the moonbases which can consist of any facility. History Lunar habitats have been designed for many different proposed moonbases. The only lunar habitats that sofar have been erected were the temporary Apollo Lunar Modules, such as Eagle of Tranquility Base, the very first. Advantages, disadvantages, problems and potential solutions Setting up structures on a natural body would provide ample sources of material for their construction, particularly for purposes such as shielding from cosmic radiation. The energy required to send objects from the Moon to space is much less than from Earth to space. This could allow the Moon to serve as a source of construction materials within cis-lunar space. Rockets launched from the Moon would require less locally produced propellant than rockets launched from Earth. Some proposals include using electric acceleration devices (mass drivers) to propel objects off the Moon without building rockets. Others have proposed momentum exchange tethers (see below). Furthermore, the Moon does have some gravity, which experience to date indicates may be vital for fetal development and long-term human health. Whether the Moon's gravity (roughly one sixth of Earth's) is adequate for this purpose is uncertain. In addition, the Moon is the closest large body in the Solar System to Earth. While some Earth-crosser asteroids occasionally pass closer, the Moon's distance is consistently within a small range close to 384,400 km. This proximity has several advantages: Building observatory facilities on the Moon from lunar materials allows many of the benefits of space based facilities without the need to launch these into space. The lunar soil, although it poses a problem for any moving parts of telescopes, can be mixed with carbon nanotubes and epoxies in the construction of mirrors up to 50 meters in diameter. It is relatively nearby; astronomical seeing is not a concern; certain craters near the poles are permanently dark and cold, and thus especially useful for infrared telescopes; and radio telescopes on the far side would be shielded from the radio chatter of Earth. A lunar zenith telescope can be made cheaply with ionic liquid. A farm at the lunar north pole could provide eight hours of sunlight per day during the local summer by rotating crops in and
