<Tr> <Td_colspan="2"> <P> </P> Left to right: Armstrong, Collins, Aldrin Apollo program ← Apollo 10 Apollo 12 → </Td> </Tr> <P> Apollo 11 was the spaceflight that landed the first two humans on the Moon . Mission commander Neil Armstrong and pilot Buzz Aldrin, both American, landed the lunar module Eagle on July 20, 1969, at 20: 18 UTC . Armstrong became the first to step onto the lunar surface six hours after landing on July 21 at 02: 56: 15 UTC; Aldrin joined him about 20 minutes later . They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth . Michael Collins piloted the command module Columbia alone in lunar orbit while they were on the Moon's surface . Armstrong and Aldrin spent just under a day on the lunar surface before rejoining Columbia in lunar orbit . </P> <P> Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center in Merritt Island, Florida, on July 16 at 9: 32 am EDT (13: 32 UTC) and was the fifth manned mission of NASA's Apollo program . The Apollo spacecraft had three parts: a command module (CM) with a cabin for the three astronauts, and the only part that landed back on Earth; a service module (SM), which supported the command module with propulsion, electrical power, oxygen, and water; and a lunar module (LM) that had two stages--a lower stage for landing on the Moon, and an upper stage to place the astronauts back into lunar orbit . </P> <P> After being sent toward the Moon by the Saturn V's upper stage, the astronauts separated the spacecraft from it and traveled for three days until they entered into lunar orbit . Armstrong and Aldrin then moved into the lunar module Eagle and landed in the Sea of Tranquility . They stayed a total of about 21.5 hours on the lunar surface . The astronauts used Eagle's upper stage to lift off from the lunar surface and rejoin Collins in the command module . They jettisoned Eagle before they performed the maneuvers that blasted them out of lunar orbit on a trajectory back to Earth . They returned to Earth and landed in the Pacific Ocean on July 24 . </P>
