 NASA, ESA, and J. Garvin (NASA/GSFC) Hubble studied these three sites on the Moon. Scientists used Hubble's ultraviolet photos of these sites and moon rocks and soil gathered in the 1970s during the Apollo missions to help them identify the minerals at these sites. Lefthand photo: The Aristarchus crater and the nearby Schroter's Valley rille (part of which shows at upper left corner) have never been visited by man or robot. |
