The Flight of the GeoCam Payload

June 1993

The GeoCam payload was designed tested and built by the CAN DO Technical Team headed up by Chief Engineer Tom O'Brien . The final payload integration and assembly was done in a clean room at Goddard Space Flight Center in Maryland.

The payload structure was designed to fit a standard NASA Get Away Special (GAS) five cubic payload canister with a fused silica window and a motorized door to allow it to photograph the Earth.

The payload structure mounted four Nikon F3 cameras (see below) each equipped with an 85mm lens. Two cameras were loaded with color film, one with positive (slide)film and one with negative (print) film. The other two cameras were loaded with high resolution black & white film and infrared black & white film . The exact combinations of film, filter and aperture were based on extensive testing done by the Can Do Technical team with the advice and consultation of the expert staff at the National Geographic Society in Washington DC.
