Solar Panels Get a Small Energy Boost
Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals now only about 492 feet 150 meters away.
The project is preparing to mask off the troubled Bank 7 sector of the Flash file system with a new version of the flight software to be uploaded shortly. On Sols 3928 and 3929 Feb. 10 and 11, 2015, Opportunity performed some targeted color Panoramic Camera Pancam observations. On Sol 3930 Feb. 12, 2015, the rover drove about 66 feet 20 meters to get a view into Marathon Valley. This was followed by a post-drive Navigation Camera Navcam panorama. Opportunity drove again on Sol 3932 Feb. 14, 2015, bumping near a potential surface target. An atmospheric argon measurement with the Alpha Particle X-ray Spectrometer APXS was made. On the following two sols a 360-degree Navcam panorama was collected.
A small dust cleaning events occurred on Sol 3934 Feb. 16, 2015 improving energy production by about 12 percent. On Sol 3935 Feb. 17, 2015, the robotic arm was used to collect a Microscopic Imager MI mosaic of the surface target Jean Baptiste Charboneau followed by an APXS placement on the same for a multi-hour integration. Opportunity drove again on Sol 3936 Feb. 18, 2015, with a 9.8-meter drive to get a better view into the interior of Marathon Valley.
As of Sol 3936 Feb. 18, 2015, the solar array energy production was 559 watt-hours with an atmospheric opacity Tau of 0.816 and an improved solar array dust factor of 0.695.
Total odometry is 26.13 miles 42.05 kilometers.

Latest Drive Puts Rover Within Marathon-Distance Record
Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals now only about 656 feet 200 meters away.
The project is operating the rover without using the Flash storage system to avoid resets associated with a corrupted portion of Flash. The project is preparing to mask off the troubled sector of Flash and resume using the remainder of the Flash file system.
On Sol 3923 Feb. 5, 2015, Opportunity drove 72 feet 21.7 meters south, following the drive with post-drive Panoramic Camera Pancam and Navigation Camera Navcam drive-direction panoramas. On the following sol, the rover completed the Navcam 360-degree panorama with more imagery.
On Sol 3925 Feb. 7, 2015, Opportunity performed the first sol of a two-sol touch n go using the robotic arm the touch to collect Microscopic Imager frames and then place the Alpha Particle X-ray Spectrometer on a surface target for a multi-hour integration. On the next sol the go, the rover drove over 102 feet 31 meters and then collected more drive direction imagery. With this drive Opportunity exceeded 26 miles 42 kilometers of driving distance on Mars.
As of Sol 3927 Feb. 9, 2015, the solar array energy production was 479 watt-hours with an atmospheric opacity Tau of 0.824 and a solar array dust factor of 0.606.
Total odometry is 26.11 miles 42 kilometers.

Rover Continues Driving While Team Works on Rover Memory Issues
Opportunity drove on Sols 3916, 3918 and 3921 Jan. 29, Jan. 31 and Feb. 3, 2015, totaling about 282 feet 86 meters. The operations strategy has been to perform pre-drive targeted imaging, then drive on the first sol of a multi-sol plan, collecting post-drive Panoramic Camera Pancam and Navigation Camera Navcam imagery in the forward direction for data return that evening. Then, on the next sol, complete the 360-degree Navcam panorama with images in the rearward direction.
As of Sol 3921 Feb. 3, 2015, the solar array energy production was 484 watt-hours with an atmospheric opacity Tau of 0.949 and a solar array dust factor of 0.632.
Total odometry is 26.08 miles 41.97 kilometers.

Several Drives This Week Put Opportunity Near Marathon Distance
Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals now about 984 feet 300 meters away.
The project is operating the rover without using the Flash storage system to avoid reset problems and is using instead random access memory RAM for temporary storage of telemetry. The project is preparing to mask off the troubled sector of Flash and resume using the remainder of the Flash file system in normal operations.
Opportunity drove on Sols 3909, 3911 and 3914 Jan. 22, Jan. 24 and Jan. 27, 2015, totaling almost 279 feet 85 meters. On the evening of Sol 3912 Jan. 25, 2015, an atmospheric argon measurement was collected with the Alpha Particle X-ray Spectrometer. Targeted color imagery is being collected as the rover makes progress towards the Spirit of St. Louis crater and Marathon Valley.
As of Sol 3914 Jan. 27, 2015, the estimated solar array energy production was 534 watt-hours with an atmospheric opacity Tau of 0.891 and an inferred solar array dust factor of 0.636.
Total odometry is 26.02 miles 41.88 kilometers.

Team Has Plan to Fix Flash Memory Issue
Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals now less than 1,312 feet 400 meters to the south.
The Flash memory degradation causes multiple resets of the rover on each wake-up. To mitigate this, the project is operating the rover without using the non-volatile Flash storage system, and using instead the volatile random access memory RAM for temporary storage of telemetry. Recently, the project was able to configure the rover to use this mode at every wakeup without the need to set this mode each time with a ground command.
Meanwhile, the project is preparing to mask off the troubled sector of Flash and resume using the remainder of the Flash file system in normal operations. The plan to implement the masking was reviewed last week by an independent panel and the project was given the go ahead.
Opportunity drove on Sols 3902, 3905 and 3908 Jan. 14, Jan. 16 and Jan. 21, 2015, totaling over 574 feet 175 meters.
As of Sol 3908 Jan. 21, 2015, the solar array energy production was 440 watt-hours with an atmospheric opacity Tau of 1.037 and a solar array dust factor of 0.596 from Sol 3906/Jan. 18, 2015.
Total odometry is 25.97 miles 41.80 kilometers.

Team Working on Strategy to Fix Flash Memory Issue
Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals now less than 1,969 feet 600 meters to the south.
The Flash memory degradation is causing multiple resets of the rover on each wake-up. To mitigate this, the project is operating the rover without using the non-volatile Flash storage system, and using instead the volatile random access memory RAM for temporary storage of telemetry. This requires real-time commanding the rover on the first day sol of each plan.
Meanwhile, the project has developed the strategy to mask off the troubled sector of Flash and resume using the remainder of the Flash file system in normal operations. The project plans to implement the masking after an independent review is held later this week.
Using RAM storage, Opportunity drove on Sol 3895 Jan. 7, 2015, to do a small turn in place. Since arriving on the summit of Cape Tribulation on Sol 3894 Jan. 6, 2015, Opportunity has been collecting a full color, 360-degree Panoramic Camera Pancam panorama.
As of Sol 3901 Jan. 13, 2015, the solar array energy production was 395 watt-hours, an atmospheric opacity Tau of 1.056 and a solar array dust factor of 0.606.
Total odometry is 25.86 miles 41.62 kilometers.

Rover Reaches the Summit of Cape Tribulation After Several Drives this Week
Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals now only about 1,969 feet 600 meters to the south.
The Flash memory continues to degrade causing multiple resets of the rover on each wake-up. To mitigate this, the project is operating the rover without using the non-volatile Flash storage system, and instead relies on the volatile random access memory RAM for temporary storage of telemetry. This requires real-time commanding the rover on the first sol of each plan. Meanwhile, the project is developing a strategy to mask off the troubled sector of Flash and resume using the remainder of the Flash file system in normal operations.
Using RAM storage, Opportunity drove on Sols 3875, 3881, 3893 and 3894 Dec. 18, 24, 2014 and Jan. 5 and Jan. 6, 2015, totaling over 656 feet 200 meters. With the drive on Sol 3894 Jan. 6, 2015, Opportunity is now on the summit of Cape Tribulation, the highest point so far on the western rim of Endeavour Crater. This point is 443 feet 135 meters above the plain of Botany Bay before the rover started climbing the rim.
As of Sol 3894 Jan. 6, 2015, the solar array energy production was 438 watt-hours, an atmospheric opacity Tau of 1.041 and a solar array dust factor of 0.631.
