The Apollo 11 spacecraft launched from Cape Canaveral on July 16, 1969. Four days later, humans walked on the surface of the moon for the first time.

A team of thousands was required to make that lunar mission a success. Dr. Al Koller was a member of that team, working in the Firing Room.

Forty-five years ago this week, the flight of Apollo 11 changed the course of human history.

On July 16, 1969, a Saturn V rocket launched from the Kennedy Space Center carrying astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin Jr. into space. Four days later, Neil Armstrong, closely followed by Buzz Aldrin, left the lunar module Eagle and walked on the surface of the moon.
