Motion of Phoenix and the ground with respect to the HiRISE detectors

Motion of Phoenix and the ground with respect to the HiRISE detectors
Motion of Phoenix and the ground with respect to the HiRISE detectors As Phoenix descended to Mars, Mars Reconnaissance Orbiter rotated to compensate for its motion, making Phoenix appear to travel in a direction perpendicular to the linear detectors of the HiRISE camera. However, the ground was moving in a different direction, at an angle to the detectors, which caused gaps in the resultant image. Courtesy of Timothy Reed
