The Mars Exploration Rover Opportunity is still exploring Mars. Below is a brief field report summary of its latest activity.

During the last week of Febraury, 2018, on Sol 4999 since landing on Mars (14 tears ago), Opportunity woke up at took a picture of the sunrise over the southeast rim of Endeavour crater. Opportunity then proceeded with its science activities here on the inner wall of Endeavour crater.

For its special sol 5000, Opportunity did a selfie using the microcopic imager on the end of the arm. The other Mars Exploration Rover, Spirit, had used the microscopic imager to do a selfie (actually just images of the of the underside of the rover to look for clearance on a rock) many years ago. But this was the first time that Opportunity had attempted a true selfie. Because the Microscopic Imager is a fixed focus "handlens", images of far away features are out of focus and the mosaic selfie is not perefct. But when these images arrived, the Science Team and Rover Engineers were a bit surprosed that the selfie  was actually pretty good. The selfie is a bit blurry, but as a sol 5000 "birthday" present, it is a great selfie from of a verteran Mars Rover on Mars. It is an excellent example of an old rover learning a new trick.

So we bumped towards the big outcrop ("Copper Cliff"). In the next plan we will center the rover work volume on a target that we have selected.

An attempt to bump left and get a small bright vein into the IDD work volume failed to get the target in the work plane. The Rover Planners figure that it could take several attempts to acquire such a tiny target. So the Science Team decided on Wednesday to bag it and move on to bigger fish. The decision was made to drive to the outcrop to the immediate west "Copper Cliff". On Friday we will then plan how to proceed. If lucky, we will have one of the lithologies within the work volume. If not, we will determine what we want to examine and bump to it for planning on Monday.


Opportunity Rover: Finished Outcrop Walk, Starting Detailed Examination of Outcrops, Looking for Clays


We on the MER Opportunity science team are currently doing an “outcrop walk” with Opportunity on the slopes of Cape York, a small residual part of the rim on the 20+ km diameter Endeavour crater, Mars.  This part of Cape York where we are currently exploring is where we have evidence for ancient clays and we would like to examine them. On Earth, when mapping the geology of an area, a geologist often walks around getting a general feel for what outcrops are present and what particular outcrops will be the best for sampling or for testing  a particular hypothesis.
