We could have a colony there by 2022
In October, Japan’s Selenological and Engineering Explorer probe discovered a large underground cave on the Moon. The cave is 100 meters (328 feet) wide and 50 kilometres (31 miles) long, which could comfortably house the population of a village. This has lead some to suggest it as a possible location for a lunar station.
Radio waves that were used to investigate the cave revealed it to possibly be structurally sound, and containing deposits of ice and water inside rocks that might be used for fuel production.
The cave is believed to be a lava tube created by volcanic activity from 3.5 billion years ago. It’s located just metres underneath volcanic domes called the Marius Hills.
Junichi Haruyama, a senior researcher with the Japan Aerospace Exploration Agency, explained that lava tubes “might be the best candidate sites for future lunar bases, because of their stable thermal conditions and potential to protect people and instruments from micrometeorites and cosmic ray radiation,” according to The Guardian.
“If we ever have a human base on another world I would bet it would be the Moon first,” senior NASA scientist Chris McKay told Futurism. “Being so close, and constantly so close, is really a killer advantage over Mars, or asteroids, or anywhere else. Like Vasco de Gama we will stay in sight of shore as we venture out.”
