NASA Astronaut JD Wetherbee : Only US Astronaut to Command 5 Space Shuttle Missions on Risk

NASA career

Wetherbee was selected as an astronaut candidate in 1984, and became an astronaut in June 1985. He piloted mission STS-32 in 1990 and commanded missions STS-52 (1992), STS-63 (1995), STS-86 (1997), STS-102 (2001), and STS-113 (2002). The final three missions were dockings with Mir and the International Space Station; STS-113 was the last Space Shuttle mission before the Columbia disaster.

Wetherbee served as Deputy Director of the Johnson Space Center (August 1995 to April 2000), Director of the Flight Crew Operations Directorate (April 2000 – 2002), and Technical Assistant to the Director of JSC's Safety & Mission Assurance Directorate (April 2003 to June 2004).

Spaceflight experience

STS-32: Columbia (January 9–20, 1990) included the successful deployment of the Syncom IV-F5 satellite, and retrieval of the 21,400-pound Long Duration Exposure Facility (LDEF) using the Remote Manipulator System (RMS). The crew also operated a variety of middeck experiments and conducted numerous medical test objectives, including in-flight aerobic exercise and muscle performance to evaluate human adaptation to extended duration missions. Mission duration was 173 orbits in 261 hours and 01 minute.

STS-52: Columbia (October 22 to November 1, 1992) successfully deployed the Laser Geodynamic Satellite (LAGEOS), a joint Italian-American project. The crew also operated the first U.S. Microgravity Payload (USMP) with French and American experiments, and successfully completed the initial flight tests of the Canadian-built Space Vision System (SVS). Mission duration was 236 hours and 56 minutes.

STS-63: Discovery (February 2–11, 1995), was the first joint flight of the new Russian-American Space Program. Mission highlights included the rendezvous with the Russian Space Station, Mir, operation of Spacehab, and the deployment and retrieval of Spartan 204. The mission was accomplished in 129 orbits in 198 hours and 29 minutes.

STS-86: Atlantis (September 25 to October 6, 1997) was the seventh mission to rendezvous and dock with the Russian Space Station Mir. Highlights included the delivery of a Mir attitude control computer, the exchange of U.S. crew members Mike Foale and David Wolf, a spacewalk by Scott Parazynski and Vladimir Titov to retrieve four experiments first deployed on Mir during the STS-76 docking mission, the transfer to Mir of 10,400 pounds of science and logistics, and the return of experiment hardware and results to Earth. Mission duration was 169 orbits in 259 hours and 21 minutes.

STS-102: Discovery (March 8–21, 2001) was the eighth Space Shuttle mission to visit the International Space Station. The mission accomplishments included the delivery of the Expedition 2 crew and the contents of the Leonardo Multi-Purpose Logistics Module, the completion of two successful spacewalks, the return to Earth of the Expedition 1 crew, as well as the return of Leonardo, the reusable cargo carrier built by the Italian Space Agency. Mission duration was 307 hours and 49 minutes.

STS-113: Endeavour (November 23 to December 7, 2002) was the sixteenth Space Shuttle mission to the International Space Station. The launch occurred on November 23, 2002, to deliver the P1 Truss segment, which provides structural support for the Space Station radiators. Endeavour also delivered a new Expedition 6 crew to the Station, returning to Earth on December 7, 2002, with the Expedition 5 crew ending their 6-month stay in space. The total mission duration was 13 days, 18 hours and 47 minutes.
