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.

Opportunity just finished up the super crater overview panorama, pulled away from the summit (here at -1380 m) and we are on our way to Marathon Valley! It's all downhill (about 70 m down in elevation) from here.

Above is a map showing the drive and 1 m contours. Note the small impact crater a few meters to the SW which is visible in the Navcam posted below.

Opportunity made it to the summit!! The view is spectacular. From here we can see all the way to the other side of the crater, we can see the rim looking north along the path to this location, and we can see far to the south, including another large impact crater that lies 10 km or so south of Endeavour.

We will be doing a Pancam color summit panorama over the next few days before moving on. Here is the Navcam pan from this location.

Despite memory problems, Opportunity is forging ahead and is now approaching the highest point on the rim of Endeavour crater. The view is beginning to be spectacular.

Above is part of the Navcam view taken on sol 3893. The view looks across the deck of the rover toward the summit which is now just a few meters away. ON the left you can see the flloor of Endeavour crater and the far rim 12 miles away.

Opportunity is continuing its drives along the rim of the 22-km diameter impact crater Endeavour. In the next few drives it will be at or near the highest peak along the rim, Cape Tribulation summit. At that point Opportunity will be as high in elevation on Mars as it will ever be. The panoramic view from that summit should be awesome. Mid summer is only a few sols away.   

Opportunity finished up its work on Wdowiak Ridge and has now continued southward along the rim of Endeavour crater. The ultimate goal is a large valley cutting through the crater rim that we have informally named “Marathon Valley”.

Opportunity continues to work its way up Wdowiak Ridge as it ascend southward along the rim of Endeavour crater. Currently Opportunity is examining some rocks  that were excavated and thrown out of a nearby small impact crater, Ulysses crater.

The various positions occupied by Opportunity as it works its way around several rock targets are shown on this overhead view of the local Navcam panoramas.

There was a stand-down of activities on Opportunity for a week or so as we emptied the flash memory and reformatted it following discovery of some “bad” flash memory blocks. Like re-formatting the memory card in you camera when it becomes troublesome, Opportunity simply wiped its data storage memory and reformatted it. This was completed about sol 3773 and currently it appears to have worked. Opportunity has re-commenced the long climb up this high and steep segment of the Endeavour crater rim.
