jet Selected by NASA in June 1985, Baker became an astronaut in July 1986 upon completion of a one-year training and evaluation program. Following the
Challenger accident, Baker was assigned from January 1986 to December 1987 as a member of the team that was pursuing redesign, modification and improvements to the Shuttle Landing and Deceleration Systems, to include nosewheel steering, brakes, tires, and drag chute, in an effort to provide greater safety margins during landing and rollout. He was then assigned to the
Shuttle Avionics Integration Laboratory, where he was involved in the checkout and verification of the computer software and hardware interfaces for
STS-26 (the return-to-flight mission) and subsequent flights. Baker then served as an ascent, entry and orbit spacecraft communicator (
CAPCOM) for Shuttle missions
STS-27,
STS-29,
STS-30,
STS-28,
STS-34,
STS-33,
STS-32,
STS-36,
STS-31,
STS-38, and
STS-35. His duties included communication with the Shuttle crew during simulations and actual missions, as well as working procedural problems and modifications between missions. He served as the leader of the Astronaut Support Personnel team at the
Kennedy Space Center for Shuttle missions
STS-44,
STS-42 and
STS-45. He was assigned as the Flight Crew Operations Directorate Representative to the
Space Shuttle Program Office from December 1992 to January 1994. Between March and October 1995, he served as the Director of Operations for NASA at the
Gagarin Cosmonaut Training Center in
Star City, Russia. He was responsible for the coordination and implementation of mission operation activities in the
Moscow region for the joint U.S./Russian Shuttle/Mir program. From October 1997 to August 2001, he was the assistant director of Johnson Space Center (JSC) for Human Space Flight Programs, Russia and was responsible for implementation and integration of NASA's Human Space Flight Programs in Russia. Those activities included
International Space Station (ISS) training, operations, technical liaison, logistics and personnel administration support. He also served as the NASA JSC representative to the
Russian Space Agency, Gagarin Cosmonaut Training Center, Star City; Mission Control Center-Moscow,
Energia Rocket and
Spacecraft Corporation, Krunichev State Scientific and Production Space Center and other Russian government agencies and manufacturers involved in the ISS program. After his return to JSC in August 2001, he was assigned as the International Space Station Program Manager for International Operations responsible for the coordination of program operations, integration and flight crew training and support activities with the International Partners.
Space flights A veteran of four
space flights, Baker has logged 965 hours in space. He served as pilot on
STS-43 (August 2–11, 1991) and
STS-52 (October 22 to November 1, 1992), and was the mission commander on
STS-68 (September 30 to October 11, 1994) and
STS-81 (January 12–22, 1997).
STS-43 Space Shuttle Atlantis launched from the Kennedy Space Center,
Florida, on August 2, 1991. During the flight, crew members deployed the fifth
Tracking and Data Relay Satellite (TDRS-E), in addition to conducting 32 physical, material, and life science experiments, mostly relating to the
Extended Duration Orbiter and
Space Station Freedom. After 142 orbits of the Earth, the 9-day mission concluded with a landing on Runway 15 at the Kennedy Space Center on August 11, 1991. Mission duration was 213 hours, 21 minutes, 25 seconds.
STS-52 Space Shuttle
Columbia launched from the Kennedy Space Center, Florida, on October 22, 1992. During the mission crew members deployed the Italian Laser Geodynamic Satellite (
LAGEOS), used to measure movement of the Earth's crust, and operated the U.S. Microgravity Payload 1 (USMP-1). Additionally, the
Advanced Space Vision System (SVS) developed by the
Canadian Space Agency was tested by the Canadian
payload specialist and the crew using a small target assembly that was released from the remote manipulator system. The SVS will be used for Space Station construction. These three primary payloads together with numerous other payloads operated by the crew encompassed geophysics, materials science, biological research and applied research for Space Station Freedom. Following 159 orbits of the Earth, the 10-day mission concluded with a landing on Runway 33 at the Kennedy Space Center on November 1, 1992. Mission duration was 236 hours, 56 minutes, 13 seconds.
STS-68 Space Shuttle
Endeavour launched from the Kennedy Space Center, Florida, on September 30, 1994. This flight was the second flight of the Space Radar Laboratory (SRL), which consists of a large radar called SIR-C/X-SAR (Shuttle Imaging Radar-C/X-Band Synthetic Aperture Radar) and MAPS (Measurement of Air Pollution from Satellites). As part of NASA's Mission to Planet Earth, SRL was an international, multidisciplinary study of global environmental change, both natural and man-made. The primary objective was to radar map the surface of the Earth to help us understand the contributions of
ecology,
hydrology,
geology, and
oceanography to changes in our Planet's environment. Real-time crew observations of environmental conditions, along with over 14,000 photographs, aided in interpretation of the radar images. This SRL mission was a highly successful test of technology intended for long-term environmental and geological monitoring of planet Earth. Following 183 orbits of the Earth, the eleven-day mission concluded with a landing on Runway 22 at
Edwards Air Force Base,
California, on October 11, 1994. Mission duration was 269 hours, 46 minutes, 10 seconds.
STS-81 Space Shuttle
Atlantis launched from the Kennedy Space Center, Florida on January 12, 1997. STS-81 was the fifth in a series of joint missions between the U.S.
Space Shuttle and the Russian Space Station
Mir and the second one involving an exchange of U.S. astronauts. In five days of docked operations more than three tons of food, water, experiment equipment and samples were moved back and forth between the two spacecraft. Following 160 orbits of the Earth the STS-81 mission concluded with a landing on Kennedy Space Center's Runway 33 ending a 3.9 million mile journey. Mission duration was 244 hours, 56 minutes. ==Post NASA==
