Seen here with its robotic arm extended studying a rock called “Athens”, the Mars Exploration Rover Opportunity is still actively involved in science even after 3,970 days on Mars!
A couple of weeks before checking out “Athens” the rover took four images with the Pancam of the area called Marathon Valley located on the western rim of Endeavour Crater from its vantage point overlooking the valley.
The scene spans from east to southeast and the image was taken on 13 March 2015. The view is very close to the true color.
In the last Curiosity post the rover had undergone a fault condition. A “transient short circuit” triggered an on-board fault-protection program to halt activity on 27 February. The mission team took a few days to test and determine the cause. In the meantime a sample from a Telegraph Hill drilling was held for testing. Satisfied the problem has been cleared, the rover continues on and the sample has been delivered to the on-board laboratory.
The plan is drive Curiosity through the Artist’s Drive valley to reach higher layers of Mount Sharp.
The map was made in part from data from the HiRISE camera on the Mars Reconnaissance Orbiter.
A problem has developed with the Mars Science Laboratory also known as Curiosity.
The image above shows the drill section of the rover after it finished drilling into “Telegraph Peak” on 24 February 2015. On 27 February 2015 as the sample was being transferred the sample powder obtained from the drilling process an electrical “irregularity” triggered a fault-protection event. The fault-protection event halted the process because it stopped the arm activity.
Telemetry indicates a transient short circuit occurred prompting the pre-programmed response to the anomolous condition by stopping activity; hopefully sparing the rover further damage. Mission managers are running tests and will continue to work through the problem. In all likelyhood Curiosity will be back to work soon — stay tuned.
The other day I was checking out images of Curiosity and thought the rover was pretty clean. Turns out only be parts of the rover are clean. This selfie shows quite a bit of dust build up.
It’s a great picture. You really should have a look at the full image at the Mars Science Laboratory website. Not only will you get a very large image with great detail on the rover, there is also the wonderful terrain.
Curious about how a rover can take a selfie?
The scene combines dozens of images taken during January 2015 by the Mars Hand Lens Imager (MAHLI) camera at the end of the rover’s robotic arm. The pale “Pahrump Hills” outcrop surrounds the rover, and the upper portion of Mount Sharp is visible on the horizon. Darker ground at upper right and lower left holds ripples of wind-blown sand and dust.
The annotated version above labels several of the sites Curiosity has investigated during three passes up the Pahrump Hills outcrop examining the outcrop at increasing levels of detail. The rover used its sample-collecting drill at “Confidence Hills” as well as at Mojave, and in late February was assessing “Telegraph Peak” as a third drilling site.
The view does not include the rover’s robotic arm. Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic’s component images. The arm was positioned out of the shot in the images, or portions of images, that were used in this mosaic.
The Mars Exploration Rover Opportunity continues to set records. Picture it, the little rover begins its mission on Mars and at the start the idea of surviving the first Martian winter was hard to believe. Now 11 years later Opportunity has traveled almost a regulation marathon’s distance.
In February 2015, NASA’s Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover’s position relative to where it could surpass that distance.
The map shows the rover’s location as of Feb. 10, 2015, in the context of where it has been since late December 2014 and the “Marathon Valley” science destination ahead. Opportunity is within about 220 yards (200 meters) of completing a marathon. The green band indicates where it could reach the official Olympic marathon-race distance of 26.219 miles (42.195 kilometers). The rover’s route might zigzag as the rover team chooses a path toward Marathon Valley, so there is uncertainty about where exactly it will pass marathon distance.
Curiosity took this image of the Martian landscape a couple of days agon on 12 February 2015.
Currently Curiosity is examining sites inside Gale Crater, recently drilling into a rock at a place called Mojave 2. The drilling technique is changing to suit the fragile rock, using a less heavy handed approach to drilling is paying off.

This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA’s Curiosity Mars Rover shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.
The scene combines multiple frames taken with Mastcam’s right-eye camera on Aug. 7, 2014, during the 712th Martian day, or sol, of Curiosity’s work on Mars. It shows an outcrop at the edge of “Hidden Valley,” seen from the valley floor. This view spans about 5 feet (1.5 meters) across in the foreground. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Figure A is a version with a superimposed scale bar of 50 centimeters (about 20 inches).
This is an example of a thick-laminated, evenly-stratified rock type that forms stratigraphically beneath cross-bedded sandstones regarded as ancient river deposits. These rocks are interpreted to record sedimentation in a lake, as part of or in front of a delta, where plumes of river sediment settled out of the water column and onto the lake floor.
