Moon Landing
Apollo 11 landed on the Moon
July 20, 1969
What Happened
On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. Their spacecraft, Apollo 11, had launched four days earlier from Kennedy Space Center in Florida. Michael Collins stayed in orbit above while his crewmates descended to the lunar surface in a small landing craft called the Eagle. Armstrong stepped out first, uttering the famous words: "That's one small step for man, one giant leap for mankind."
The Race to Get There
The Moon landing was the finish line of a decade-long race between the United States and the Soviet Union. The Soviets had beaten America into space — first with Sputnik in 1957, then with Yuri Gagarin in 1961. President Kennedy responded by promising a Moon landing before the end of the 1960s. NASA had just eight years to figure out how to do it.
Why It Still Matters
The Apollo program employed 400,000 people and produced technology that found its way into everyday life — from scratch-resistant lenses to memory foam. Armstrong and Aldrin spent about two and a half hours on the surface, collecting 21 kilograms of rock samples. Those samples are still studied today and helped confirm theories about how the Moon formed. Use the date calculator to see exactly how many days ago humanity first touched another world.
