One of the earliest NASA astronauts, “Pete” Conrad was the third man to walk on the moon. It was the crowning achievement of his NASA career, which included four space trips totaling more than 1,180 hours in space.
He also flew twice during the Gemini program, and spent 28 days on the first U.S. space station, Skylab, in 1973. Before joining NASA, Conrad was a flight instructor and test pilot at the Navy Test Pilot School in Patuxent River, Md. Lately, he was working on opening up space to civilians for vacation trips. Conrad died July 8 from injuries suffered in a motorcycle accident in California. He was 69.
