Neil Armstrong became the first human to walk on the Moon during Apollo 11.
Apollo 11 was NASA’s first crewed lunar landing mission. It launched from Florida on July 16, 1969, with Armstrong as commander, Michael Collins as command-module pilot, and Edwin “Buzz” Aldrin as lunar-module pilot.
Armstrong and Aldrin landed the lunar module Eagle in the Moon’s Sea of Tranquility on July 20, 1969. Armstrong stepped onto the lunar surface first, followed by Aldrin about 19 minutes later. Collins remained in lunar orbit aboard the command module Columbia.
The astronauts spent more than two hours outside the lunar module, collecting samples, taking photographs, and deploying scientific instruments. Apollo 11 returned safely to Earth on July 24. A common mix-up is naming Aldrin, who was the second person on the Moon, or Collins, who never walked on the lunar surface.
