Neil Alden Armstrong (born August 5, 1930) is a former American astronaut, test pilot, and Naval Aviator, and was the first human to set foot on the Moon. Armstrong's first spaceflight was Gemini 8 in 1966, for which he was the command pilot. On this mission, he performed the first manned docking of two spacecraft together with pilot David Scott. Armstrong's second and last spaceflight was as mission commander of the Apollo 11 moon landing mission on July 20, 1969. On this famous "giant leap for mankind", Armstrong and Buzz Aldrin descended to the lunar surface and spent 2.5 hours exploring, while Michael Collins orbited above.
