Example of Surface Composition Maps:TES, CRISM and HiRISE and  research for 2021 landing site

TES: Hematite

​

Notice that there is only one area with a large concentration of Hematite.

location of Hematite

Current Research Results using HiRISE and CRISM:

The USA rover, Perseverance, landed in Jezero Crater, Mars on 2/18/2021. One mission goal is to find signs of past life.  Many of the instruments you have been learning about were used to determine where these signs of life might be as illustrated below from two recent research projects by research scientists. These scientists knew which type of surface materials would be the most likely to show signs of past life. They use JMARS to find them!

These minerals and groups are formed on earth in a wet environment where life possibly could have existed or where evidence of life could be found.
