Soviet robotic lander Luna 17 still sitting on Mare Imbrium
where it delivered the Lunokhod 1 Rover in November 1970, LROC
NAC Image M114185541RE. NASA's Goddard Space Flight Center built
and manages the mission for the Exploration Systems Mission
Directorate at NASA Headquarters in Washington. The Lunar
Reconnaissance Orbiter Camera was designed to acquire data for
landing site certification and to conduct polar illumination
studies and global mapping. Operated by Arizona State
University, LROC consists of a pair of narrow-angle cameras
(NAC) and a single wide-angle camera (WAC). The mission is
expected to return over 70 terabytes of image data.
