missions. Slayton created a crew rotation, where a crew would be selected as the backup crew for a mission and would later be the prime crew three missions later. During the Apollo 1 fire, Slayton was in the Cape Canaveral LC-34 blockhouse. He was a close friend of fellow astronaut Gus Grissom and had considered working inside the capsule to determine communications problems and would have worked under the footrests, where the fire would later begin. After the fire, Slayton called a meeting of the astronauts from the first groups to be chosen, in April 1967 and announced that they were the candidates for the first lunar landing. Slayton oversaw the crew reassignments for the upcoming Apollo missions, as well as the selection for

Shepard would be later reassigned to command Apollo 14 by the Office of Manned Spaceflight director George Mueller, against Slayton's wishes, who felt that Shepard needed additional training time. After the postal covers scandal during the Apollo 15 mission, Slayton reassigned the crew to non-flying jobs, effectively ending their astronaut careers. Slayton supported keeping

Return to flight status

While grounded, Slayton took several measures to attempt to be restored to flight status, including regularly exercising, taking vitamins, quitting cigarette smoking and coffee and reducing his consumption of alcoholic beverages. In 1970 his palpitations became more frequent and he started taking experimental daily doses of

, a crystalline alkaloid. This treatment was successful, but concerned that taking medication would still disqualify him from solo flying, Slayton stopped taking it against doctors orders. After a decade of seeing doctors around the world, in 1971 Slayton was examined at the Mayo Clinic after a long period without heart fibrillation, and was determined to not have a coronary condition. On March 13, 1972, NASA announced that Slayton had returned to flight status.


Apollo–Soyuz flight

Post-NASA career

After his retirement from NASA, Slayton served as president of Space Services Inc., a Houston-based company earlier founded to develop rockets for small commercial payloads. He served as mission director for a rocket called the Conestoga, which was successfully launched on September 9, 1982, and was the world's first privately funded rocket to reach space. Slayton also became interested in aviation racing, and was President of International Formula One Pylon Air Racing and

of Columbia Astronautics. He also served on the COMSTAC, Department of Transportation's Commercial Space Advisory Committee. In 1991, Slayton began working with space historian Michael Cassutt to write his autobiography, titled ''Deke!: U.S. Manned Space from Mercury to the Shuttle'', which was published in 1994, a year after his death.

Personal life

Slayton married Marjorie "Marge" Lunney (1921–1989) on May 18, 1955, and they had one son, Kent Sherman, born April 8, 1957. They divorced in April 1978, and Slayton moved to a condominium near the Johnson Space Center. He married Bobbie Belle Jones (1945–2010), who also worked at NASA, in October 1983, and they remained married until his death. When Slayton was a test pilot, one of his pilot colleagues was also named Don. In order to avoid confusion in radio communications, Slayton was referred to by his initials, D.K., which were eventually shortened to "Deke." In 1992, Slayton was diagnosed with a malignant brain tumor. On June 13, 1993, he died in his home in League City, Texas, from the illness, at the age of 69.
