![]() ![]() The objective of this mode is to identify new scientifically interesting locations that could be further investigated. In this mode CRISM will map half of Mars within a few months after aerobraking and most of the planet after one year. In the untargeted mode, CRISM reconnoiters Mars, recording approximately 50 of its 544 measurable wavelengths at a resolution of 100 to 200 meters per pixel. The instrument has two modes, a multispectral untargeted mode and a hyperspectral targeted mode. In addition, CRISM is monitoring ice and dust particulates in the Martian atmosphere to learn more about its climate and seasons.ĬRISM measures visible and infrared electromagnetic radiation from 370 to 3920 nanometers in 6.55 nanometer increments. All of these materials have characteristic patterns in their visible-infrared reflections and are readily seen by CRISM. ![]() ![]() These materials include iron and oxides, which can be chemically altered by water, and phyllosilicates and carbonates, which form in the presence of water. In order to do this, CRISM is mapping the presence of minerals and chemicals that may indicate past interaction with water - low-temperature or hydrothermal. CRISM is being used to identify locations on Mars that may have hosted water, a solvent considered important in the search for past or present life on Mars. ![]()
