Field Report From Mars: Sol 4410 - June 20, 2016

Opportunity is finishing up its activities here in Marathon Valley, on the western rim of the 22 km-diameter Endeavour impact crater. Over the past few weeks it has been “walking” along a ridge inspecting the outcrops. From orbit this location was spied as containing significant clay minerals, so the rocks here have been studied carefully.

A closer look at the valley. Marathon Valley is an unusually deep “cut” in the rim of Endeavour. This may be part of the reason why we are seeing something a little different here. But maybe not. Science can be peculiar that way. (Which is why scientists tend to be skeptical of everything and test everything. When a bunch of scientists start saying the same thing, then you have some pretty significant results to talk about.) Those are 1 meter contours.
