Paper Abstract

The Viking Project required a space-hardened, sterilizeable camera which would survive external temperature, 200 MPH sand storms and a landing on Mars. The approach used to satisfy these constraints will be discussed. The resulting camera was a facsimile design with mechanical scanning and an array of photosensors which were electrically selectable to provide focussing, spectral range selection and resolution selection. The camera provided PCM digital output of the video data and interfaced with an on-board computer to select azimuth and elevation pointing angles data rates, selection of black and white or color imaging, etc. The camera has resolution equivalent to a human observer, positional accuracy equivalent to a metric camera and radiometric accuracy sufficient to relate intensity changes to material and topographical characteristics of the planet.
