Rear Admiral Thomas K. Mattingly II (USN, Ret.), born March 17, 1936, in Chicago, Illinois, and deceased October 31, 2023, was a distinguished U.S. Navy pilot and NASA astronaut. A graduate of Auburn University with a B.S. in Aeronautical Engineering (1958), he served as a naval aviator before being selected as a NASA astronaut in 1966. Originally slated for Apollo 13, he instead flew as Command Module Pilot on Apollo 16 (1972), orbiting the Moon and performing an EVA, and later commanded two Space Shuttle missions, STS-4 (1982) and STS-51C (1985), logging over 504 hours in space. Mattingly held numerous honors, including the NASA and Navy Distinguished Service Medals, and contributed significantly to Apollo suit development and early Shuttle flight testing. He retired from NASA in 1985 and was survived by his son, Thomas III. Courtesy of NASA.
