Apollo 11 was the spaceflight that first landed humans on the Moon. It was one of the most-awaited occasion for all the NASA’s team and not only. The first person to step onto the Moon was Neil Armstrong. 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 stayed on
the lunar surface for six hours on July 21 at 02:56:15 UTC; Aldrin joined him
19 minutes later.
They spent about
two and a quarter hour together outside the spacecraft, and collected 47.5
pounds (21.5 kg) of lunar material to bring back to Earth.
pilot Michael Collins flew the command module Columbia alone in lunar orbit
while they were on the Moon’s surface.
So, Armstrong and Aldrin spent 21.5 hours on the lunar surface at a site they named Tranquility Base before rejoining Columbia in lunar orbit.
