Spaceflight Experience

STS-37 Atlantis (April 5-April 11, 1991) was launched from the Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. During the 93 orbits of the mission, the crew deployed the Gamma Ray Observatory (GRO) to study gamma ray sources in the universe. GRO, at almost 35,000 pounds (16 Mg), was the heaviest payload deployed to date by the Shuttle Remote Manipulator System (RMS). The crew also conducted an unscheduled space walk to free the GRO high gain antenna, and conducted the first scheduled extravehicular activity in 5½ years to test concepts for moving about large space structures. Several middeck experiments and activities were conducted including test of elements of a heat pipe to study fluid transfer processed in microgravity environments (SHARE), a chemical processing apparatus to characterize the structure of biological materials (BIMDA), and an experiment to grow larger and more perfect protein crystals than can be grown on the ground (PCG II). Atlantis carried amateur radio equipment for voice contact, fast scan and slow scan TV, and packet radio. Several hundred contacts were made with amateur radio operators around the world. Mission duration was 143 hours, 32 minutes, 44 seconds.

STS-59 Endeavour (April 9-April 20, 1994) was the Space Radar Laboratory (SRL) mission. SRL consisted of three large radars, SIR-C/X-SAR (Shuttle Imaging Radar C/X-Band Synthetic Aperture Radar), and a carbon monoxide sensor that were used to enhance studies of the Earth's surface and atmosphere. The imaging radars operated in three frequencies and four polarizations. This multispectral capability of the radars provided information about the Earth's surface over a wide range of scales not discernible with previous single-frequency experiments. The carbon monoxide sensor MAPS (Measurement of Air Pollution by Satellite) used gas filter radiometry to measure the global distribution of CO in the troposphere. Real-time crew observations of surface phenomena and climatic conditions augmented with over 14,000 photographs aided investigators in interpretation and calibration of the data. The mission concluded with a landing at Edwards AFB after orbiting the Earth 183 times in 269 hours, 29 minutes.

STS-76 Atlantis (March 22-March 31, 1996) was the third docking mission to the Russian space station Mir. Following rendezvous and docking with Mir, transfer of a NASA astronaut to Mir for a 5-month stay was accomplished to begin a continuous presence of U.S. astronauts aboard Mir for the next two-year period. The crew also transferred 4800 pounds (2,200 kg) of science and mission hardware, food, water and air to Mir and returned over 1100 pounds (500 kg) of U.S. and ESA science and Russian hardware. Godwin performed a six-hour spacewalk, the first while docked to an orbiting space station, to mount experiment packages on the Mir docking module to detect and assess debris and contamination in a space station environment. The packages will be retrieved by a future shuttle mission. The Spacehab module carried in the Shuttle payload bay was utilized extensively for transfer and return stowage of logistics and science and also carried Biorack, a small multipurpose laboratory used during this mission for research of plant and animal cellular function. This mission was also the first flight of Kidsat, an electronic camera controlled by classroom students via a Ku-band link between JSC Mission Control and the Shuttle, which uses digital photography from the Shuttle for science and education. The STS-76 mission was accomplished in 145 orbits of the Earth, traveling 3.8 million miles (6.1 Gm) in 221 hours and 15 minutes.

STS-108 Endeavour (December 5-December 17, 2001) was the 12th shuttle flight to visit the International Space Station. Endeavour’s crew delivered the Expedition-4 crew and returned the Expedition-3 crew. The crew unloaded over 3 short tons (2.7 Mg) of supplies, logistics and science experiments from the Raffaello Multi-Purpose Logistics Module and repacked over 2 short tons (1.8 Mg) of items no longer needed on the station for return to Earth. Godwin used the Shuttle’s robotic arm to install the MPLM onto the Station Node, and participated in a space walk to wrap thermal blankets around ISS Solar Array Beta Gimbal Assemblies. STS-108 was accomplished in 185 Earth orbits, traveling 4.8 million miles (7.7 Gm) in 283 hours and 36 minutes.
