Apollo 11

Apollo 11 (July 16–24, 1969) was the fifth manned flight in the United States Apollo program and the first spaceflight to land humans on the Moon. Commander Neil Armstrong and Lunar Module Pilot Edwin “Buzz” Aldrin landed the Lunar Module Eagle on July 20 at 20:17 UTC, and Armstrong became the first person to step onto the surface about six hours later, at 02:56 UTC on July 21. Aldrin joined him 19 minutes afterward, and together they spent about two and a half hours exploring the site they had named Tranquility Base upon landing. They collected 47.5 pounds (21.5 kg) of lunar material before re-entering the Lunar Module. In total, they were on the Moon’s surface for 21 hours, 36 minutes before returning to the Command Module Columbia, which remained in lunar orbit, piloted by Michael Collins.
