Ken Mattingly

Thomas Kenneth Mattingly II was born on March 17, 1936, in Chicago, Illinois, and built his path to space through naval aviation. He flew as a carrier pilot, logging hours in the A-1H Skyraider and the A-3B Skywarrior, before attending the U.S. Air Force Aerospace Research Pilot School at Edwards Air Force Base. By the time NASA selected him in 1966, he was an experienced naval aviator who would go on to accumulate thousands of flight hours over his career. Meticulous and engineering-minded, Mattingly quickly became one of the astronaut corps' most trusted technical specialists, serving as the astronaut representative in the development and testing of the Apollo spacesuit and its life-support backpack, and supporting the Apollo 8 and Apollo 11 crews, before receiving a flight assignment of his own.

Mattingly's career is inseparable from Apollo 13. Named command module pilot for that mission, he was removed from flight status just days before launch after being exposed to German measles through backup crewman Charlie Duke; Mattingly never developed the illness, but the decision stood and Jack Swigert took his seat. When an oxygen tank ruptured en route to the Moon, he joined the ground effort in Houston, working long hours in the simulator to help devise the delicate power-up sequence that safely returned the crippled spacecraft and its crew to Earth. Two years later he flew his own lunar voyage as command module pilot of Apollo 16, launched on April 16, 1972. Orbiting the Moon aboard the command module Casper while Young and Duke worked the surface, Mattingly operated a suite of scientific instruments, then performed a deep-space extravehicular activity on the return to retrieve film cassettes from the service module's instrument bay. He later commanded two Space Shuttle flights: STS-4 aboard Columbia in June 1982, the fourth and final orbital test flight of the Shuttle, and STS-51-C aboard Discovery in January 1985, the first mission dedicated entirely to the Department of Defense. Across three missions he logged roughly 504 hours in space.

Mattingly retired from NASA in 1985 and from the U.S. Navy, where he had reached the rank of rear admiral, the following year, afterward working in the aerospace industry. He is remembered as much for the mission he did not fly as for the two he commanded: the man grounded by a measles scare who then helped save the lives of the Apollo 13 crew from a console in Mission Control. Portrayed prominently by Gary Sinise in the 1995 film Apollo 13, he became one of the more widely recognized figures of the Apollo era. Ken Mattingly died on October 31, 2023, at the age of eighty-seven, remembered as a rigorous engineer and aviator whose calm competence shaped some of the defining moments of American spaceflight.
