Latest Spirit Update
Spirit Remains Silent at Troy
Spirit Status for sol 2621-2627
Release Date: 5/26/11

More than 1,300 commands were radiated to Spirit as part of the recovery effort in an attempt to elicit a response from the rover. No communication has been received from Spirit since Sol 2210 (March 22, 2010). The project concluded the Spirit recovery efforts on May 25, 2011. The remaining, pre-sequenced ultra-high frequency (UHF) relay passes scheduled for Spirit on board the Odyssey orbiter will complete on June 8, 2011.

Total odometry is unchanged at 7,730.50 meters (4.80 miles).


Latest Opportunity Update
Rover Continues Driving While Team Works on Rover Memory Issues
Opportunity Status for sol 3915-3921
Release Date: 2/5/15

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.

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).
