Lunar Reconnaissance Orbiter
NASA's Lunar Reconnaissance Orbiter orbit will make a high-resolution map of the composition of the lunar surface and seek out potential sources of water-ice that may exist in the bottom of dark polar craters. If found, water ice could be a used by astronauts to make fuel, air and perhaps grow food on the Moon.
The mission is a key step in NASA's plan to send astronauts back to the Moon.
