Apollo 11 was the spaceflight which landed the first humans, Neil Armstrong and Edwin "Buzz" Aldrin, Jr, on Earth's Moon in 1969. Launched from the Kennedy Space Center Florida on July 16, Apollo 11 was the 5th manned mission, and the 3rd lunar mission, of NASA's Apollo program. A Saturn V launched Apollo 11 from Launch Pad 39A, part of the Launch Complex 39 site at the Kennedy Space Center. It entered orbit 12 minutes later. After one and a half orbits, the S-IVB third-stage engine pushed the spacecraft onto its trajectory toward the Moon.
