Using data collected by an American instrument on India’s Chandrayaan-1 lunar orbiter scientists have produced the first global map showing the locations and quantities of trace water on the Moon.
The map above, reduced to post here, is the result. The green areas at high latitudes show the most evidence of water, but the amounts remain very tiny, and the evidence remains somewhat uncertain.
Regardless, this map indicates that the high latitudes of the Moon will likely be the most valuable real estate for future colonists.
