Ken Mattingly was a student at the Air Force Aerospace Research Pilot School when NASA selected him as an astronaut in April 1966. His first assignment was to be the Command Module Pilot on the Apollo 13 mission. Three days prior to launch, he was removed from the mission due to exposure to German measles, which he never contracted. As a result, he missed the dramatic in-flight explosion yet safe return of the crew. However, Mattingly was involved in helping the crew solve the problem of power conservation during re-entry. He finally flew as Command Module Pilot for Apollo 16. Commander John Young, Lunar Module pilot Charles Duke, and Mattingly were launched on April 16, 1972. Young and Duke explored the lunar surface for three days while Mattingly used instruments mounted in the service module from an altitude of 100 km to photographically and geochemically map a band of the lunar surface around the equator.
