Selected by NASA in January 1990, Halsell became an astronaut in July 1991. A five flight veteran, Halsell has logged over 1,250 hours in space. He was the pilot on
STS-65 (July 8–23, 1994) and
STS-74 (November 12–20, 1995), and commanded
STS-83 (Apr 4–8, 1997),
STS-94 (July 1–17, 1997) and
STS-101 (May 19–29, 2000). From February to August 1998, he served as NASA Director of Operations at the
Yuri Gagarin Cosmonaut Training Center, Star City, Russia. Halsell also served as manager of Shuttle Launch Integration at
Kennedy Space Center, Florida, from July 2000 to January 2003. Halsell was responsible for Space Shuttle preparation, launch, and return on 13 missions. After the
Columbia accident, he led the NASA Return to Flight Planning Team, responsible for implementing the recommendations of the accident investigation board into the Shuttle Program, and resulted in the resumption of missions in 2005. He then served as the Assistant Director for Aircraft Operations Division of the Flight Operations Directorate. Halsell retired from NASA in November 2006 to accept a position with
ATK Launch Systems, where he served as Vice President of Space Exploration Systems, and was the ATK site manager at
Marshall Space Flight Center, Huntsville, Alabama. On October 10, 2011, Halsell joined
Dynetics, as a technical director in their Space Division.
Spaceflights STS-65 flew the second International Microgravity Laboratory (IML-2). During the 15-day flight, the crew conducted more than 80 experiments focusing on materials and life sciences research in microgravity. The mission was accomplished in 236 orbits of the Earth, traveling 6.1 million miles in 353 hours and 55 minutes. STS-74 was NASA's second Space Shuttle mission to rendezvous and dock with the Russian Space Station Mir. During the 8-day flight, the Atlantis crew successfully attached a permanent docking module to Mir and transferred over 2,000 pounds of food, water and scientific supplies for use by the cosmonauts. The STS-74 mission was accomplished in 129 orbits of the Earth, traveling 3.4 million miles in 196 hours, 30 minutes, 44 seconds. STS-83, the Microgravity Science Laboratory (MSL-1) Spacelab mission, was cut short because of problems with one of the Shuttle's three fuel cell power generation units. Mission duration was 95 hours and 12 minutes, traveling 1.5 million miles in 63 orbits of the Earth. STS-94, a re-flight of the Microgravity Science Laboratory (MSL-1) Spacelab mission, focused on materials and
combustion science research in microgravity. Mission duration was 376 hours and 45 minutes, traveling 6.3 million miles in 251 orbits of the Earth. STS-101 was the third Shuttle mission devoted to International Space Station (ISS) construction. Objectives included transporting and installing over 5,000 pounds of equipment and supplies, and conducting a spacewalk. The mission was accomplished in 155 orbits of the Earth, traveling 4.1 million miles in 236 hours and 9 minutes. == DUI and reckless murder charges ==
