Alfred Merrill "Al" Worden (born February 7, 1932), (Col, USAF, Ret.), is an American astronaut and engineer who was the Command Module Pilot for the Apollo 15 lunar mission in 1971.
One of only 24 people to have flown to the Moon, he orbited it 74 times in the Command Module Endeavour.During Apollo 15's return flight to Earth, Worden performed an extravehicular activity to retrieve film cassettes from the exterior of the spacecraft, the command and service module.
It was the first "deep space" EVA in history, at great distance from any planetary body.
As of 2019, it remains one of only three such EVAs which have taken place, all during the Apollo program's J-missions.
