Destination Moon—Astronaut Group 5 (the "Original Nineteen"), Part VIII
Thomas Kenneth Mattingly II (17 March 1936-31 October 2023), Rear Admiral, U.S. Navy—He flew as Command Module Pilot on Apollo 16 (Casper & Orion, 1972), Commander on S.T.S.-4 (Columbia, 1982), & CDR on S.T.S.-51-C (Discovery, 1985); he was replaced as C.M.P. on Apollo 13 just three days before launch due to the risk of measles; post-N.A.S.A. & the Navy, he helped develop the X-33.

Commentary: We regret not marking Rear Admiral Mattingly's death when it occurred, one month shy of three years hence (31 October 2023), especially since we did note Frank Borman's death, one week later (7 November 2023). In October 2023, "The Explorers' Club" observed the sixtieth anniversary of the selection of Astronaut Group 3.

In the feature film Apollo 13 (1995), Mattingly was played by Gary Sinise.
