Dark Light
Dr. Gerald A. Soffen (February 7, 1926 — November 22, 2000) was a project scientist for the NASA’s Viking program of Mars landers.

This crater on Mars was named after him, and this image covers a small portion of the crater floor.

Here, we see a diversity of bedrock colors and textures and wind-blown (aeolian) features.

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.

Layers in Meridiani Planum

Also visible in a Context Camera image, our high resolution picture shows layers exposed where the crater ejecta has been eroded.
