Mission Specialist (MS) Thornton rolls DSO 404 strip chart on middeck

STS008-14-378 (30 Aug-5 Sept 1983) --- Astronaut William E. Thornton, a very busy mission specialist conducting a great deal of bio-medical experimentation, checks a prolific roll of data in the mid deck of the Earth-orbiting Space Shuttle Challenger. The electrode on Dr. Thornton’s forehead indicates that his four crewmates were not his only test subjects during the extensive test on this six-day flight.
