Moon Day is celebrated on July 20th of each year to commemorate the famous moon landing by the crew of Apollo 11 on July 20, 1969.
A total of twelve people have landed on the Moon. This was accomplished with two US pilot-astronauts flying a Lunar Module on each of six NASA missions across a 41-month time span starting on 21 July 1969 UTC, with Neil Armstrong and Buzz Aldrin on Apollo 11 (with Armstrong being first to set foot on the surface), and ending on 14 December 1972 UTC with Gene Cernan and Jack Schmitt on Apollo 17 (with Cernan being the last to step off the lunar surface). All Apollo lunar missions had a third crew member who remained onboard the Command Module. The last three missions had a rover for increased mobility.
