Lunar Pits


Pits are remarkable features that provide a window into the subsurface. Their origin is somehow related to the volcanic plumbing system that transported lava that flooded the mare basins. The big question is – what do they lead into? An open cave system (in the form of lava tubes) or a dead end? An LROC image of the Mare Tranquillitatis pit taken when turning the spacecraft 45° showed that the floor extends at least 25 meters under the surface (yellow arrows connect like features). But how far does the floor extend? 50 meters, 100 meters, 1000 meters? What a great target for a robotic explorer – spelunking on the Moon!
