Universe Today – Living Underground on Other Worlds. Exploring Lava Tubes

Future Moon and Mars colonists will already be facing a life underground, to hide from the surface radiation, micrometeorite bombardment, extreme temperatures and to create a usable atmosphere. These natural tunnels will save them the hard work of needing to dig the tunnel.

The natural roofs on these caverns are thought to be 10 meters or more thick, with one site estimated to have a roof that’s 45-90 meters thick. This would be more than enough to protect against solar radiation and galactic cosmic radiation.
