Dark Light
Data from other instruments, such as THEMIS and CRISM, imply that chlorides are present here; the CRISM data reveal that iron/magnesium clays are also present.

Our goal is to compare textures and determine stratigraphy for these two materials. Enhanced color very useful for mapping units of distinct composition.

Sunken and Pitted Ejecta

The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area (north is up, west is to the left).

Layered Bedrock

This un-named crater in southwestern Arabia Terra contains a treasure! Layered sediments are the key to the puzzle of Martian history. They tell us about the conditions that existed when the sediments were deposited, and how they changed over time.
Terra Sabaea

Possible Impact Melt in Terra Sabaea

Nighttime and daytime infrared images from THEMIS suggest a consolidated deposit in the floor of this ancient crater in Terra Sabaea, potentially with some bedrock exposure.

The Saga of Airy-0

Up to now, we’ve never imaged Airy-0, a crater within Airy Crater that formerly was used to define zero longitude on Mars.
