SPIRIT UPDATE:  Spirit Remains Silent at Troy - sols 2621-2627, May 18-24, 2011:

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).

OPPORTUNITY UPDATE:  Just In Time For Halloween, A Network Problem And An Amnesia Event Slows Down Robotic Arm Work - sols 4181-4187, October 28, 2015-November 03, 2015:

Opportunity is within 'Marathon Valley' on the west rim of Endeavour Crater.

The plan ahead was for Opportunity to use the robotic arm to place the Alpha Particle X-ray spectrometer down on a target for a week while the project conducted a weeklong test and readout of Flash memory. However, a Deep Space Network problem prevented the rover's plan from being radiated, so the rover executed run out plans on Sols 4184 and 4185 (Oct. 31 and Nov. 1, 2015).

On Sol 4186 (Nov. 2, 2015), commands were sent to the rover to enable the use of Flash memory and to spend the week returning science data already in Flash memory. Although those commands were successful, the rover experienced an amnesia event on Sol 4186 (Nov. 2, 2015). As contingency, Flash Bank 7 readouts were performed instead. On Sol 4187 (Nov. 3, 2015), the rover successfully mounted Flash and began the return of the science data. The plan for the balance of the week is to continue with the return of science data from Flash.

As of Sol 4187 (Nov. 3, 2015), the solar array energy production was 344 watt-hours with an atmospheric opacity (Tau) of 0.472 and a solar array dust factor of 0.574.

Total odometry is 26.48 miles (42.62 kilometers), more than a marathon.
