United States Navy personnel of the Vietnam War

Ronald_E._Evans

Ronald Ellwin Evans Jr. (November 10, 1933 – April 7, 1990) was an American electrical engineer, aeronautical engineer, officer and aviator in the United States Navy, and NASA astronaut. As Command Module Pilot on Apollo 17 he was one of the 24 astronauts to fly to the Moon, and one of 12 people to fly to the Moon without landing.
Before becoming an astronaut, Evans graduated with a Bachelor of Science degree in electrical engineering from the University of Kansas and joined the U.S. Navy in 1956. After receiving his naval aviator wings, he served as a fighter pilot and flew combat missions during the Vietnam War. In 1964 he received a Master of Science degree in aeronautical engineering from the U.S. Naval Postgraduate School. Achieving the rank of captain, he retired from the Navy in 1976.
Evans was selected as an astronaut by NASA as part of NASA Astronaut Group 5 in 1966 and made his only spaceflight as command Module pilot aboard Apollo 17 in December 1972, the last crewed mission to the Moon, with Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt. During the flight, Evans and five mice orbited the Moon a record 75 times as his two crewmates descended to and explored the surface. He is the last person to orbit the Moon alone and, at 147 hours and 43 minutes, holds the record for the most time spent in lunar orbit. During Apollo 17's return flight to Earth, Evans performed an extravehicular activity (EVA) to retrieve film cassettes from the service module. It was the third "deep space" EVA, and is the spacewalk performed at the greatest distance from any planetary body. As of 2024, it remains one of only three deep space EVAs, all made during the Apollo program's J-missions. It was the final spacewalk of the Apollo program.
In 1975, Evans served as backup Command Module Pilot for the Apollo–Soyuz Test Project mission. He worked on the development of the Space Shuttle before retiring from NASA in March 1977 to become a coal industry executive.
