Although the Curiosity rover has been in the limelight the past few weeks, and for good reason, elsewhere on Mars the Opportunity rover continues its studies of the region around the rim of the huge Endeavour crater. Yes, she’s still there!
The rover is now in an area where clays have been identified from orbit, a prime target of the rover, as clays indicate a past watery environment which was non-acidic (ph neutral). It isn’t known exactly what these deposits might look like on the ground, but the rover is now investigating an interesting-looking outcrop of darker rock right in one of the clay deposit areas. Does it contain some of the long-sought clays? We don’t know yet, but it is still a curious-looking outcrop even if it doesn’t. It’s a mix of thin “fin-like” pieces, similar to others seen before in other locations, and other blocky chunks. Appearance-wise, it resembles dry, eroding clays on Earth.
