There's a new hole in the Moon, shown this week by the Lunar Reconnaissance Orbiter (LRO) Camera team, apparently one of five such discoveries mentioned in a July 27th Nature News report. This ten-meter crater on the northeast edge of Mare Tranquillitatis on the Moon's near side appeared between the August 1971 Apollo 15 image (left) and LRO's September 2009 image. NASA has had a program involving amateur observers since 2005 watching for such impacts (PDF with 200+ candidates). See also news from last September about fresh Mars craters.
