What is CRISM?
The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is 1 of 6 science experiments on the Mars Reconnaissance Orbiter, which takes measurements of both the surface and the atmosphere of Mars.
CRISM data are used to find minerals’ spectral signatures on Mars. Different minerals form in different settings, ranging from ancient lakes and deltas to volcanic lava flows. We use the mineral evidence to understand how different geologic processes have shaped the planet over time. CRISM also observes the polar ice caps and atmosphere to understand seasonal and year-to-year variations in the Martian weather.

CRISM Spectral Library
The MRO CRISM Spectral Library is an analysis tool for interpreting CRISM data. it currently contains 2,260 spectral analyses of 1,134 Mars-analog samples, all measured under desiccating conditions so that materials that adsorb water look as they would on Mars. This was made avaialble to the community through the PDS on the day that MRO entered Mars orbit!

What is planetary geology?
Planetary geology is the study of the geological processes that have occurred or are ongoing on planets, moons, asteroids, and comets.
MSL Site Selection
CRISM has been supporting landing site selection for the Mars Science Laboratory (MSL) mission with hundreds of observations that have been converted to color and mineral indicator maps. [ more ]
In June 2011, CRISM science and operations team members received two NASA Public Service Group Achievement Awards for an outstanding mission. At the same time, CRISM's PI received a NASA Distinguished Public Service Medal.
