A quarter moon is visible in this oblique view of Earth's horizon and airglow, recorded with a digital still camera on the final mission of the Space Shuttle Columbia. Columbia's crew was killed on Feb. 1, 2003 when the shuttle broke up on re-entry into Earth's atmosphere. NASA
Apollo 8 served as the first manned lunar orbit mission, and the first manned flight of the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle. Lift off occurred on December 21, 1968. This photograph of Earth above the lunar horizon is one of many taken by the crew.
