Short answers, pulled from the story.
Ronald Evans holds the record for the most time spent in lunar orbit: 147 hours, 43 minutes, and 37.11 seconds, achieved during the Apollo 17 mission in December 1972. He also orbited the Moon 75 times, more than any other person, and is the last individual to orbit the Moon alone.
On the return journey from the Moon, Evans performed a one-hour, five-minute, 44-second extravehicular activity to retrieve film cassettes and camera equipment from the Scientific Instrument Module bay. It was the third deep space EVA in history, performed farther from any planetary body than nearly any other spacewalk, and was the final spacewalk of the entire Apollo program.
Evans served as a naval aviator and fighter pilot, flying Vought F8U Crusaders and completing 112 combat missions during the Vietnam War. He earned a Bachelor of Science in electrical engineering from the University of Kansas in 1956 and a Master of Science in aeronautical engineering from the U.S. Naval Postgraduate School in 1964.
Ronald Ellwin Evans Jr. was born on the 10th of November 1933, in St. Francis, Kansas. He died on the 6th of April 1990, in Scottsdale, Arizona, at the age of 56, from a heart attack in his sleep.
Evans flew Apollo 17 in December 1972 with Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt. While Cernan and Schmitt descended to and explored the Taurus-Littrow valley, Evans remained in the Command Module America in lunar orbit.
After leaving NASA in March 1977, Evans worked as a marketing executive in the coal industry in Scottsdale, Arizona, then as Director of Space Systems Marketing at Sperry Flight Systems, which made instrumentation for the Space Shuttle. He later formed his own consulting company and partnered with a Japanese entrepreneur building a space-exploration theme park.
