For decades the thought of colonising the Moon has tantalised scientists and visionaries alike. Various colonies have graced our screens, from the sprawling Moonbase Alpha in Space: 1999 to the compact mining colony in Moon.
A lunar colony is arguably the next logical step for mankind. It is our nearest stellar neighbour, a mere 238,000 miles (383,000km) away, which makes resupplying relatively easy. One attraction is the comparatively abundant supply of Helium-3 on the moon, which is an ideal fuel for fusion reactors.
Various space programmes have theoretically mapped out a route for establishing a permanently manned lunar colony. China has expressed interest in a base on the far side of the Moon. It was revealed in October 2015 that Esa and Roscosmos are planning a series of missions to the Moon to assess the possibilities for permanent settlement.
