Compact Reconnaissance Imaging Spectrometer for Mars (CRISM)

NSSDCA ID: 2005-029A-02

Mission Name: Mars Reconnaissance Orbiter
Principal Investigator:Dr. Scott Murchie


The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) on the Mars Reconnaissance Orbiter is a hyperspectral imaging spectrometer designed to map the surface mineralogy of Mars. In particular it will be looking for evidence of aqueous and hydrothermal deposits and other mineralogical indicators of water. It will be used to search for layering of surface features and will monitor the pattern and density of dust and ice clouds.

CRISM will measure 560 individual wavelengths of sunlight reflected from the surface in the range from 400 to 4050 nanometers (visible to shortwave infrared) at 6.55 nanometers/channel. At a nominal 300 km altitude CRISM has a field of view 18 meters wide and 10.8 km long, with a spatial resolution of 18 meters. Over the first year of the mission CRISM will map the entire planet at a resolution of 100 to 200 meters. Based on these maps, targets will be selected for higher resolution imaging. Total estimated cost of CRISM is $17.6 million.
