Lunarpedia is a wiki for planning to get back to the Moon. Its topic area covers everything that can have a Lunar settlement perspective. Lunarpedia is meant to be the Moon Society's successor to the Artemis Data Book, this time allowing contributions from space enthusiasts everywhere. After it's initial success, an idea hatched among Lunarpedia contributors that the Wiki concept could be applied to Mars missions and enthusiasts, which resulted in the founding of Marspedia.
As of December 2018, Lunarpedia is still online and being active worked on by The Moon Society.
