Mapping Luna

Using altimeter data from the Lunar Reconnaissance Orbiter, scientists have put together the most detailed topographical map of the lunar surface to date. The true, established roughness of the surface suggests the Moon's past was even more violent than scientists had thought-- and they'd already thought it was pretty violent.

The new map can also help those planning to settle Luna. By identifying areas that are permanently in shadow, and therefore constantly cold, the map can tell us where water ice might exist on the surface-- a key to the success of future outposts and settlements.
