Astronaut Winston E. Scott works in the opened cargo bay of the Shuttle Endeavour. This spacewalk took place on February 17th, 1996, during mission STS-72, (1/11/96 - 1/20/96), during which time NASA was able to evaluate space station assembly techniques. At center left is the Canadarm, used to recover satellites. At the back of the cargo bay are two gold-colored satellites. The nearer, square satellite is the American Office of Aeronautics and Pace (OAST) Flyer. The round satellite is the Japanese Space Flyer Unit, (SFU-1).
