Michael Collins, born October 31, 1930, selected as part of the third group of fourteen astronauts in 1963, he flew into space twice. His first spaceflight was on Gemini 10, in which he and Command Pilot John Young performed two rendezvous with different spacecraft and undertook two extra-vehicular activities (EVAs, also known as spacewalks). His second spaceflight was as the Command Module Pilot for Apollo 11. While he stayed in orbit around the Moon, Neil Armstrong and Buzz Aldrin left in the Lunar Module to make the first manned landing on its surface. He is one of 24 people to have flown to the Moon. Collins was the fourth person, and third American, to perform an EVA; and is the first person to have performed more than one EVA. As Neil Armstrong and Edwin ''Buzz'' Aldrin took man's first steps on the moon, a third crew member orbited high above. Astronaut Michael Collins waited in the command module while his fellow astronauts spent more than 21 hours on the lunar surface. He was the first astronaut to orbit the far side of the moon alone; on each pass on the far side, he was cut off from human contact on Earth because there were no satellites available to relay his communications back to Earth.
