Two Viking spacecraft scheduled to land on Mars in the summer of 1976 will return multispectral panoramas of the Martian surface with resolutions 4 orders of magnitude higher than have been previously obtained and stereo views with resolutions approaching that of the human eye. Mission constraints and uncertainties require a carefully planned imaging investigation that is supported by a computer model of camera response and surface features to aid in diagnosing camera performance, in establishing a preflight imaging strategy, and in rapidly revising this strategy if pictures returned from Mars reveal unfavorable or unanticipated conditions.
计划于1976年夏天登陆火星的两艘海盗号航天器将传回火星表面的多光谱全景图，其分辨率比之前获得的高出4个数量级，还将传回分辨率接近人眼的立体视图。任务的限制和不确定性要求进行精心规划的成像调查，该调查由相机响应和表面特征的计算机模型提供支持，以帮助诊断相机性能、制定飞行前成像策略，以及在从火星传回的图片显示出不利或意外情况时迅速修改该策略。
