Bio
Walker studied aeronautical and astronautical engineering at Purdue University and joined McDonnell Douglas after graduation. His work centered on electrophoresis processing equipment, a commercial microgravity research system intended to study material separation in space.
NASA flew Walker on STS-41-D, STS-51-D, and STS-61-B in 1984 and 1985. On each mission he operated the Continuous Flow Electrophoresis System and helped demonstrate how private-industry experiments could be integrated into shuttle operations.
After his flights, Walker remained active in space-industry and education work. His career is important because it sits between NASA astronaut operations, commercial payload development, and the early shuttle-era experiment economy.
