The features that will be considered for observation on Mars are reviewed. The mission requirements, which are dictated by the features, are discussed. The mission scenarios assume the utilization of the H-2 launch vehicle. Additionally, spacecraft system structures are reviewed. Features that will be considered for observation by Mars satellites are as follows: (1) topographical and geographical features of the Mars surface; (2) material compositions and mineral resources on the Mars surface; (3) composition, pressure, and water vapor content of the Mars atmosphere; (4) vertical structure of the Mars atmosphere; and (5) the climate on Mars (clouds, polarcaps, and sand dusts). Mission operational requirements for exploration vehicle configurations (Mars-oriented and Earth-oriented), including mission equipment installation, onboard data processing, communication, attitude control, electric power source, and solar paddle systems, are reviewed. It is concluded that the Earth-oriented configuration is suitable for high-resolution local topography missions and the Mars-oriented configuration is suitable for atmospheric observation of the Martian surface.
