David Randolph Scott (born June 6, 1932) (Col, USAF, Ret.) is a retired test pilot and NASA astronaut who was the seventh person to walk on the Moon. The commander of Apollo 15, Scott was selected as an astronaut as part of the third group in 1963. Scott flew three times in space, and is the only living commander of an Apollo mission that landed on the Moon and one of four surviving Moon walkers.Before becoming an astronaut, Scott graduated from the United States Military Academy at West Point and joined the Air Force. After serving as a fighter pilot in Europe, he graduated from the Air Force Experimental Test Pilot School and the Aerospace Research Pilot School. Scott retired from the Air Force in 1975 with the rank of colonel, and more than 5,600 hours of logged flying time.
As an astronaut, Scott made his first flight into space as pilot of the Gemini 8 mission, along with Neil Armstrong, in March 1966, spending just under eleven hours in low Earth orbit. Scott then spent ten days in orbit in March 1969 as Command Module Pilot of Apollo 9, a mission that extensively tested the Apollo spacecraft, along with Commander James McDivitt and Lunar Module Pilot Rusty Schweickart.
After backing up Apollo 12, Scott made his third and final flight into space as commander of the Apollo 15 mission, the fourth manned lunar landing and the first J mission. Scott and James Irwin remained on the Moon for three days. Following the return to Earth, Scott and his crewmates fell from favor with NASA after it was disclosed they had carried 400 unauthorized postal covers to the Moon. After serving as director of NASAs Dryden Flight Research Center in California, Scott retired from the agency in 1977. Since then, he has worked on a number of space-related projects and served as consultant for several films about the space program, including Apollo 13.
