Looking Back at Our Moon

NASA's latest exploration spacecraft to Mars (MRO) is now 6 million miles away from Earth, when it stretches its muscle, pointing its high resolution camera at our Moon. At this distance, assuming we are in the MRO, the Moon would be as small as a shiny star. But to MRO's high resolution camera, what it saw was a beautiful crescent shown above. Once it is in Mars orbital, it is going to discern a Martian object as small as a coffee table! Using this wonderful camera, NASA hopes to locate the ill-fated Mars Polar Lander and another ill-fated lander made by Europian Space Agency.
