NASA
The project's main success came in 1969 when Neil Armstrong and Buzz Aldrin landed on the Moon as part of Apollo 11. The mission was a big success for NASA and over six million people watched it worldwide. After Apollo 11, six more Apollo flights went to the moon. Five of them landed. The one that did not land, Apollo 13, had to abort its mission when an oxygen tank exploded in the spaceship. Apollo 17 was the last mission to land on the Moon.
