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 LibraryThe 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! |
The MICA Files » ![]() The MICA Files is a compilation of published descriptions and type locations of unique spectral features identified on Mars by using data from CRISM. Learn more » CRISM Quickmap
Revealing Questions What is an emission phase function?An emission phase function (EPF) is a sequence of multiple measurements of the same target from different viewing angles through the atmosphere over a short time while the Sun’s light source is constant. This allows better characterization of the dust and gas in the atmosphere that contribute to every CRISM targeted image. CRISM Facts CRISM data were essential in helping choose the landing site for the Mars Science Laboratory mission (the Curiosity rover) and will help with the Mars 2020 Rover! |
