NASA’s Lunar orbiter discovered a total 200 lunar pits on Moon’s surface. The size of such a hole ranges from 900 meters in diameter down to 5 meters. Robert Wagner, an Arizona State University researcher, had the following to say: “A habitat placed in a pit — ideally several dozen meters back under an overhang — would provide a very safe location for astronauts: no radiation, no micrometeorites, possibly very little dust, and no wild day-night temperature swings,”
As it was also stated above by one of the researchers who helped discover the holes, these pits could provide a safe place where astronauts could stay. For now the proposed method of further exploring the underground caves which connect two or more holes would be to drop drones. The aim would be to control or program these drones to explore the surroundings from within the unknown tunnels.
Meanwhile NASA’s moon surface will be scanned and researchers want to see an increase in search algorithms. For them this is very important as it could prove to be critical, especially if mankind wants to house one day astronauts in or on the moon.
