Russia wants to build a base in the Moon’s underground tunnels

Back in 2008, the Japanese Kaguya spacecraft made a fascinating discovery when it found a metres-deep cave in the Sea of Tranquility. Amazed by the find, NASA had its orbiting Lunar Reconnaissance Orbiter Camera (LROC) to have in the depth scan of the area, which came back with high res images, like the one above. Scientists believe these are actually entrances to a complex labyrinth of lunar tunnels. Now, one of the most renowned Russian cosmonaut Sergei Krikalev claims that these caves are actually an idea spot for placing a colony.
