Gordon served as command module pilot of Apollo 12 in November 1969, orbiting the Moon 45 times aboard the command module Yankee Clipper while crewmates Pete Conrad and Alan Bean landed on the surface. During his time in orbit he photographed candidate landing sites for future missions.
Gordon logged a total of 315 hours and 53 minutes in space across his two missions. Of that time, 2 hours and 41 minutes were spent in extravehicular activity.
In May 1961, Gordon won the Bendix Trophy race from Los Angeles to New York City, flying an F4H-1 Phantom II at an average speed of 869.74 miles per hour. He completed the transcontinental flight in 2 hours and 47 minutes, setting a new speed record for the route.
Gordon was slated to command Apollo 18 and walk on the Moon as part of that mission. The mission was canceled due to budget cuts, leaving him as one of the few Apollo astronauts who orbited the Moon but never landed.
After retiring from NASA and the Navy in January 1972, Gordon served as executive vice president of the New Orleans Saints football club from 1972 to 1976.

He served as the first project test pilot for the F4H-1 Phantom II and logged more than 4,500 hours of flying time before NASA selected him in October 1963 as part of its third astronaut group.
