“This picture — click to enlunanate — is from the Lunar Reconnaissance Orbiter, and shows a region of the Moon inside the crater Henry Frères. Taken on March 7, 2010, the image shows an area just 500 meters (550 yards) across — if it were Earth, you could easily walk across it in less than ten minutes — and shows objects down to less than a meter in size.”
