He began astronaut training in February 1984 and served as backup payload specialist to Marc Garneau for space shuttle mission STS-41-G, which flew October 5 to 13, 1984.
His team designed and tested an experimental "anti-gravity suit" that may help astronauts withstand the effects of extended spaceflight on the cardiovascular system.
During this 17-day flight aboard the Space Shuttle Columbia, he and his six crewmates performed 43 experiments devoted to the study of life and materials science.
This training program involves advanced instruction on both shuttle and space station systems, EVA (spacewalking), robotic operations, and Russian language.
Within the NASA Astronaut Office, Thirsk served as a CapCom (capsule communicator) for the International Space Station (ISS) program.
CapComs speak directly with the space station crew, and assist with technical planning for the mission and last-minute troubleshooting.
