Apollo 11 history: the first Moon landing and its key moments

Apollo 11 history begins with a launch that changed space travel forever. On July 16 at 13:32 UTC, the American spaceflight lifted off atop a Saturn V rocket from Kennedy Space Center in Florida and headed for the Moon.

The mission carried Neil Armstrong, Michael Collins, and Edwin “Buzz” Aldrin, and all three were flying their second and final spaceflight. Armstrong was the commander, Collins stayed in lunar orbit aboard Columbia, and Aldrin flew beside Armstrong into the landing phase.

Why was Apollo 11 sent to the Moon?

Apollo 11 fulfilled the national goal set by President John F. Kennedy in May 1961: land a man on the Moon and return him safely before the end of the decade. That goal gave the flight its purpose, and Apollo 11 became the American spaceflight that first landed humans on the Moon.

Armstrong’s earlier flight was Gemini 8 in March 1966, where he took part in the first docking of two spacecraft. By the time Apollo 11 launched, all three astronauts were experienced fliers, but the mission still carried the pressure of a first attempt at the Moon.

How did the Moon landing happen?

Armstrong and Aldrin landed in the Sea of Tranquility on July 20 at 20:17 UTC. While they descended, Collins remained in lunar orbit aboard Columbia, waiting for the return trip.

About six hours after landing, Armstrong became the first human to walk on the Moon. Nineteen minutes later, Aldrin followed him onto the surface. Armstrong’s first steps came with the line: “That’s one small step for [a] man, one giant leap for mankind.”

The two Moonwalkers spent around two and a half hours walking on the surface and collected 21.5 kg of lunar material. Their time outside the spacecraft was short by human standards, but it marked the first walk on another world.

What did people see and hear during Apollo 11?

Armstrong’s moonwalk was broadcast live to an estimated 600 million viewers, roughly one-fifth of the world’s population. That made the landing a shared event for people watching across the globe, even while the astronauts were on the Moon itself.

The mission also had a tense backdrop in space race history. On July 21, while Armstrong and Aldrin were still on the lunar surface, the Soviet Union’s Luna 15 crashed on the Moon.

What happened after the Moon landing?

Apollo 11 did not end on the Moon. The mission returned safely to Earth on July 24, splashing down in the Pacific Ocean. The flight had begun with a Saturn V launch from Florida and ended with a safe ocean recovery, closing the first Moon-landing mission in American spaceflight.

The names attached to Apollo 11—Armstrong, Aldrin, and Collins—became part of the story of the first Moon landing. Armstrong became the first person to walk on the Moon, Aldrin followed him onto the surface, and Collins kept the command module in lunar orbit until the return.

Apollo 11 history is really the story of a launch, a landing, a walk on the Moon, and a safe return. Now test how well you know the mission.
