Opportunity: Seeking clay minerals

4335-6-pancamSols 4335-6, April 4-5, 2016. After driving back closer to the head of Marathon Valley, where slopes are not as steep, Opportunity’s Pancam has shot a series of filtered images to identify likely outcrop targets to examine closely. The warm-tinted areas in the composite image above are thought to include the sought-after clay minerals first spotted from orbit. (For more on the geological background of this location, see here and here.)

This image combines Pancam frames from Sols 4335 and 4336; the false-color images were created by Holger Isenberg. Click to enlarge.
