NASA is reaching plans to develop a permanent colony on our moon, Luna. Some Astronomers plan to colonize Mars, but there are a number of reasons that the Moon is the best place to start space colonization, but the basis of most of them are its proximity to the Earth. Most of these stem from the lower cost of access to the Moon. There are also important engineering, economic and political advantages to starting colonization with the Moon. So humans will most likely inhabit Luna before any other planet or moon.
