Apollo 11 blasted off on July 16, 1969. Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins were the astronauts on Apollo 11.
Four days later, Armstrong and Aldrin landed on the moon.
They landed on the moon in the Lunar Module. It was called the Eagle. Collins stayed in orbit around the moon. He carried out experiments and took pictures.
On July 20, 1969, Neil Armstrong became the first human to step on the moon. He and Aldrin walked around for three hours. They did experiments and picked up bits of moon dirt and rocks for later analysis.
The two astronauts returned to orbit, joining Collins. On July 24, 1969, all three astronauts came back to Earth safely.
