Paper Abstract

A "time dilation" push-broom imaging CCD sensor is being considered for certification of landing and roving sites for the Mars Rover/Sample Return Mission. It would be used to certify several candidate sites of 10 km by 10 km. Rocks and holes of size 1 m and larger will be identified using an optical sensor with 0.25 m resolution. This requires a large aperture camera and a camera pointing control system designed for high accuracy and stability. The imaging time is stretched out by a factor of 8 over the time required to fly directly over the imaged site to reduce the data rate and to increase the exposure time. Six parallel data strings are used to reduce the data rate through each string to a manageable 25 Mbps.
