Scientists are trying to prove that life is possible on moon; however, no one has ever been on the moon longer than three days. It has not been possible largely because space suits alone can't protect astronauts from extreme temperature variation, radiation, and meteorite impacts. The moon has no atmosphere or magnetic field to protect its inhabitants unlike Earth. According to a research inside of intact lava tube is the safest place to seek shelter.
A new study has confirmed the existence of a large open lava tube in the Marius Hills region of the moon, which could be utilised to protect astronauts from dangerous conditions on the surface of the moon. When a lava flow develops a hard crust, which thickens and forms a roof above the still-flowing lava stream lava tubes are formed. When the lava stops flowing, the tunnel sometimes drains; as a result a hollow void is formed. Knowing the existence of these lava tubes is also a difficult task. A senior researcher at JAXA, Japan's space agency analyzed radar data from the SELENE spacecraft to detect existing lava tubes. They found a special kind of echo pattern which they believe is evidence of a tube near the entrance to the lava tube. For a lava tube to be detectable by gravity data, it would need to extend several kilometres in length and at least one kilometre in height and width. Research is going on to get more accurate results.
