STS-56 MS2 Cockrell with HERCULES camera at overhead window W8 on OV-103's FD

STS056-08-018 (8-17 April 1993) --- Aboard Discovery, astronaut Kenneth D. Cockrell, mission specialist, records Earth imagery with the Hand-Held, Earth-Oriented, Real-Time, Cooperative, User-Friendly, Location-Targeting and Environmental System (HERCULES). HERCULES is a device that makes it simple for Shuttle crew members to take pictures of Earth, as they merely point a modified 35mm camera and shoot any interesting feature, whose latitude and longitude are automatically determined in real-time. The powder-box shaped attachment is the Inertial Measurement Unit (IMU) for the system. The STS-56 crew downlinked a number of the still images during the flight, while others are likely to be stored on disc and returned to Earth with the crew.
