>>5 Six instruments will be carried by the 2005 Mars Reconnaissance Orbiter to achieve these objectives:
High Resolution Imaging Science Experiment (HiRISE):←たぶんこれだろう This visible camera can reveal small-scale objects in the debris blankets of mysterious gullies and details of geologic structure of canyons, craters, and layered deposits.
Compact Reconnaissance Imaging Spectrometers for Mars (CRISM): This instrument splits visible and near-infrared light of its images into hundreds of "colors" that identify minerals, especially those likely formed in the presence of water, in surface areas on Mars not much bigger than a football field.
Context Imager (CTX): This camera will provide wide area views to help provide a context for high-resolution analysis of key spots on Mars provided by HiRISE and CRISM.
Shallow Subsurface Radar (SHARAD): This sounding radar will probe beneath the Martian surface to see if water ice is present at depths greater than one meter. [More]
Mars Climate Sounder (MCS): This atmospheric profiler will detect vertical variations of temperature, dust, and water vapor concentrations in the Martian atmosphere.
