Neil Armstrong, the first man to walk on the moon, has died. He was 82 years old.

Armstrong was an American astronaut and the commander of the Apollo 11 spacecraft on its mission to put men on the moon.

Apollo 11 was launched on July 16, 1969, and began orbiting the moon three days later. On July 20, Armstrong and his co-pilot, astronaut Edwin E. “Buzz” Aldrin, took off from Apollo 11 in a small landing craft called Eagle. A third astronaut, Michael Collins, remained in the main ship, orbiting the moon until they returned.

Hundreds of millions of people around the world watched on TV as the Eagle landed on the moon. When Armstrong stepped out of the ship and onto the moon’s surface, he said, “That’s one small step for (a) man, one giant leap for mankind.”*

Armstrong and Aldrin explored the moon for more than two hours and collected about 50 pounds of moon rocks. They left behind a plaque which said: “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

The Eagle remained on the moon for about 21 hours and then rejoined Apollo 11 for the return trip to Earth. Once the astronauts were back on Earth, they spent 16 days in quarantine to make sure they had not brought back any germs from space.
