As part of the Apollo program by NASA, 24 astronauts flew nine lunar missions between December 1968 and December 1972. During six successful two-man landing missions, twelve men walked on the lunar surface, six of whom drove Lunar Roving Vehicles as part of the last three missions. Three men have reached the Moon twice, one on both an orbital mission and a circumlunar flight, while the other two landed once apiece after previous orbital missions. As of August 2025, five of the 24 remain alive.
Apart from these 24 men and the three men and one woman on the Artemis II lunar flyby in 2026, no human has gone beyond low Earth orbit. Several non-human animals have circled or orbited the Moon, including two tortoises, several turtles, and five mice.
Apollo 8 and 10–17 were the nine crewed Apollo lunar missions. Apollo 4–6 and AS-201 and AS-202 were uncrewed, while AS-203 is considered a test flight. The Apollo program included three other crewed missions: Apollo 1 (AS-204) did not launch and its crew died in a ground-based capsule fire, while Apollo 7 and Apollo 9 were low Earth orbit missions that tested spacecraft components and docking maneuvers. Apollo missions 18, 19, and 20 were canceled. Twelve astronauts later flew unused Apollo command modules in the Apollo Applications Program's Skylab and Apollo–Soyuz Test Project. Of the 24 astronauts who reached the Moon, two went on to command a Skylab mission, one commanded Apollo–Soyuz, one flew as commander for Approach and Landing Tests of the Space Shuttle, and two commanded orbital Space Shuttle missions.
