Selection and training Selected as an astronaut candidate in 1978, Coats became a NASA astronaut in August 1979. He was a member of the
STS-4 astronaut support crew, and was a capsule communicator (
CAPCOM) for
STS-4 and
STS-5. A veteran of three
space flights, Coats flew on
STS-41-D in 1984,
STS-29 in 1989, and
STS-39 in 1991. From May 1989 to March 1990, he served as Acting
Chief of the Astronaut Office.
STS-41-D On his first mission, Coats was pilot on the crew of
STS-41-D, which launched from
Kennedy Space Center, Florida, on August 30, 1984. This was the maiden flight of the Orbiter
Discovery. The mission was delayed three times over a two-month period prior to liftoff. Delays included the first pad abort of the Shuttle program (and the first for NASA since
Gemini 6A) as well as a fire on the launch pad. During this 6-day mission the crew successfully activated the OAST-1 solar cell wing experiment, deployed three satellites (SBS-D, SYNCOM IV-2, and TELSTAR 3-C), operated the CFES-III experiment, the student crystal growth experiment, and
photography experiments using the
IMAX motion picture camera. The crew earned the name "Icebusters" in successfully removing hazardous ice particles from the orbiter using the
Remote Manipulator System. STS-41-D completed 96 orbits of the Earth before landing at
Edwards Air Force Base, California, on September 5, 1984.
STS-61-H In February 1985, Coats was selected as the commander of
STS-61-H, which was subsequently canceled after the
Challenger accident.
STS-29 As commander of
STS-29, Coats and his crew launched from
Kennedy Space Center aboard
Discovery on March 13, 1989. During this highly successful five-day mission, the crew deployed a
Tracking and Data Relay Satellite (TDRS), and performed numerous secondary experiments, including a Space Station "
heat pipe" radiator experiment, two student experiments, a protein crystal growth experiment, and a
chromosome and plant cell division experiment. In addition, the crew took over 3,000 photographs of the earth using several types of cameras, including the
IMAX 70 mm movie camera. Mission duration was 80 orbits and concluded with a landing at Edwards Air Force Base, California, on March 18, 1989. With the completion of his second mission, Coats has logged a total of 264 hours in space.
STS-39 Coats commanded a seven-man crew on
STS-39, an unclassified eight-day
Department of Defense mission launched from the Kennedy Space Center, Florida on April 28, 1991. Crew members worked around the clock in two-shift operations during which they deployed, operated and retrieved the
SPAS-II spacecraft, in addition to conducting various science experiments including research of both natural and induced phenomena in the Earth's atmosphere. After completing 134 orbits of the Earth,
Discovery and her crew landed at the Kennedy Space Center, Florida on May 6, 1991. With the completion of his third mission, Coats has logged over 463 hours in space.
Johnson Space Center director In November 2005, Coats was hired as the 10th director of the Johnson Space Center (JSC). Coats retired from NASA on December 31, 2012. == Post-astronaut career ==
