Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) Science Objectives
The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) is designed to acquire images of the martian surface with a spatial resolution of 6 meters (~20 ft) per pixel over a swath about 30 kilometers (18.6 mi) wide. CTX is a Facility Instrument, the operation of which is led by the MRO MARCI science team.
Main objective: To obtain images that provide context for the very high spatial resolution pictures to be obtained by the MRO High Resolution Imaging Science Experiment (HiRISE) and the high spectral resolution MRO Compact Reconnaissance Imaging Spectrometer for Mars (CRISM).
Stereo: By rolling the MRO spacecraft so that its instruments are pointed at specific targets, it will be possible to obtain stereo pairs of images for selected areas on Mars. CTX stereo images will be used to understand the planets geology and geomorphology, as well as to help refine understanding of candidate future Mars landing sites.
Mosaics: Rolling of the MRO spacecraft so that it can point the instruments at specific targets will also permit opportunities to build up mosaics over large areas of interest at the 6 meters per pixel scale. Areas of interest include, for example, the vast sedimentary rock outcrops of northern Sinus Meridiani and western Candor Chasma.
