Huge amounts of water in the Moons poles has encouraged NASA and the European Space Agency, ESA, to lead projects designed to let us settle in distant and harsh environments such as the Moon. Projects are now under way such as the ESA's MoonVillage, which might be a first step in the exploration of Mars, as it would also act as a 'pit stop'. However, in order to live on the Moon, this episode explores the difficulties we face, including low gravity, lack of atmosphere, extreme temperatures, and chances of meteor impacts. This episode uses stunning CGI and archive to explore.
