Lunarpedia
Lunarpedia is a wiki dedicated to lunar science, education, development and research. Lunarpedia is an educational public resource provided by The Moon Society, which is a US-based 501c3 tax-exempt non-profit organization.
Lunarpedia's mission is to cover everything we will need to know how to do on Luna (the Earth's moon) to set up self-sustaining bases and colonies, as well as related efforts, designs, and business models that may eventually lead there. Construction is underway and you can help!
Lunarpedia has some sister sites, a general space wiki at Exoplatz, a space dictionary at Exodictionary, a Mars wiki at Marspedia, and scientific fiction at Scientifiction.org.
