Abstract

The Mariner 9 spacecraft was inserted into orbit around Mars on 14 November 1972. The spacecraft carried two slow scan vidicon camera systems; the wide angle camera had a focal length of 50 millimeters and an 11 by 14 degree rectangular field of view; the narrow angle camera had a 500 millimeter focal length and a 1.1 by 1.4 degree field of view. The spacecraft orbit had a 65 degree inclination and the orbital period was approximately twelve hours. During the first 120 days of the mission, images were taken on opposite sides of the planet within each 24 hour period. At the start of orbital operations, approximately 60 images per day were returned. The number of frames per day decreased toward the end of the mission, and a total of 7,000 frames were transmitted by June 1972. The spacecraft operations for a typical Martial orbit are shown in figure 1.
