Multiple Instruments Used for Mars Carbon Estimate

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. This image from NASA's 2001 Mars Odyssey spacecraft show part of the floor of an unnamed crater in Noachis Terra.

Dunes

The soil at this location has a different texture than any that NASA's Mars rover Opportunity has seen earlier. The largest features on the ground in this image are a few inches or centimeters across.

Gale Crater

This image taken by NASA's 2001 Mars Odyssey shows just one of the many channels located in the northern part of Terra Sabaea which is heavily fractured and channeled, breaking up into a chaotic terrain as the elevation drops down to the northern plains.
