"A" - Apollo 11 was the spaceflight that first landed
humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz
Aldrin, both American, landed the Apollo Lunar Module Eagle on July 20, 1969,
at 20:17 UTC. Armstrong became the first person to step onto the lunar surface
six hours 39 minutes later on July 21 at 02:56 UTC; Aldrin joined him 19
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. Command module pilot Michael Collins flew the command module Columbia
alone in lunar orbit while they were on the Moon's surface. Armstrong and
Aldrin spent 21 hours 31 minutes on the lunar surface at a site they named
Tranquility Base before lifting off to rejoin Columbia in lunar orbit.
