Flight
controllers celebrate the successful conclusion of the Apollo 11 lunar
landing mission on July 24, 1969, at NASA's Mission Control Center in
Houston. On July 20, Apollo 11 astronaut Neil Armstrong planted the
first human foot on another world.
With more than half a billion people
watching on television, he climbed down the ladder and proclaimed:
"That's one small step for a man, one giant leap for mankind."
