Heflin began working at Houston's Manned Spacecraft Center (now Johnson Space Center) on June 6, 1966. His initial role was as a ground test vehicle engineer and test conductor for the development and qualification of water recovery hardware and procedures for the
Apollo command module. He was also a director for the command module's reaction control subsystem deactivation and pyrotechnic safing team. He was on the prime recovery ships during the splashdowns and post-landing activities of
Apollo 8,
Apollo 10,
Apollo 16,
Apollo 17, each of the three
Skylab missions, and the
Apollo-Soyuz Test Project. Heflin then worked as a flight controller for orbiter electrical and environmental systems for the
Space Shuttle Approach and Landing Tests as well as the Shuttle's first nine missions. Heflin progressed up the chain of command to work as a flight director, beginning with the April 1985 flight of
STS-51D. He went on to oversee 20 Space Shuttle flights, with seven as lead flight director in charge of overall operations on the ground. Heflin was lead flight director for: •
STS-30 (May 1989), which deployed the Magellan planetary probe to Venus •
STS-34 (October 1989), which deployed the
Galileo probe to Jupiter •
STS-41 (October 1990), which deployed the
Ulysses probe to the sun •
STS-44 (November–December 1991), a Department of Defense mission that also deployed the unclassified Defense Support Program Satellite •
STS-47 (September 1992), which carried the Spacelab payload •
STS-61 (December 1993), the first Hubble Space Telescope repair and servicing mission •
STS-65 (July 1994), the second flight of the International Microgravity Laboratory When the Space Shuttle
Columbia broke up on February 1, 2003, Heflin was serving as chief of the flight director office. That same day, he took part in an emotional press conference in which he and Shuttle Program Manager
Ron Dittemore outlined the details of the accident as they knew them at that point. That job was followed by a stint as deputy director of the Mission Operations Directorate, an organization of approximately 3,000 government and contractor employees responsible for the planning, training and flying of humans in space. In 2007, he became associate director (technical) at JSC. At one time or another, Heflin has also been a charter member and deputy manager of the EVA (
extravehicular activity) Project Office and served on the NASA Space Flight Safety Panel and as JSC's Ombudsman. He was also a member of the NASA Advisory Council Task Force on
International Space Station Operational Readiness. On March 1 of 2013, Milt Heflin retired from NASA. == Team name ==
