Notable for his participation in the Apollo 16 lunar mission; the STS-4 voyage of the Space Shuttle Columbia; and the STS-51-C flight of the Space Shuttle Discovery, this NASA astronaut was also originally on the Apollo 13 crew roster, but did not participate in this mission because of concerns that he had contracted measles.
After completing his B.S. in Aeronautical Engineering at Auburn University, he enlisted in the United States Navy and went on to train at Edwards Air Force Base's Air Force Aerospace Research Pilot School.
Upon ending his career with NASA, he worked for the Lockheed Martin and General Dynamics corporations.
Born Thomas Kenneth Mattingly II, he spent his early years in Chicago, Illinois and Hialeah, Florida.
He and John Young were both crew members on the Apollo 16 mission of 1972.
