This Day in History: Armstrong Walks on Moon

This Day in History: , Armstrong Walks on Moon.
July 20, 1969.
More than a billion people were
listening when Armstrong uttered
those immortal words: "That's one
small step for man, one giant leap for mankind.".
Moments after his left foot
became the first to touch the
lunar surface, Armstrong was
joined by "Buzz" Aldrin.
Two hours later, both men were
back in the lunar module, the
"Eagle." They slept on the moon
before rejoining the command module.
Getting astronauts to the
moon was the biggest non-military
human effort in Earth's history.
It cost $24 billion, involving more
than 400,000 people.
Other missions to the
moon followed.
Human beings have not set
foot on the moon since 1972
