STS008-07-149 (2 Sept 1983) --- Many hours were spent, by its crew members, running tests with the Payload Flight Test Article (PFTA) and the Remote Manipulator System (RMS). The bar-bell shaped test device and the arm stand out brilliantly against the darkness of space. The two TV cameras on the "wrist" and "elbow" of the Canadian-built robot arm provided some close-up scenes of the variegated testing with the PFTA. This frame was exposed with a 35mm camera aimed through the windows on the flight deck of the Earth-orbiting Space Shuttle Challenger.
