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:  Prepping for Comet Siding Spring Imaging - sols 3806-3812, October 08, 2014-October 14, 2014:

Opportunity is on the west rim of Endeavour Crater heading towards 'Marathon Valley,' a putative location for abundant clay minerals only a mile (1.6 kilometers) to the south.

The rover is examining the ejecta field of the small crater named 'Ulysses' and preparing for observations of Comet Siding Spring later in the week. On Sol 3806 (Oct. 8, 2014), Opportunity took a late evening set of Panoramic Camera (Pancam) images as a preliminary test of imaging the comet.

On the next sol, Opportunity bumped 5 inches (13 centimeters) to get off some small rocks under the wheels. On Sol 3809 (Oct. 11, 2014), there looked to be a small rock underneath the left front wheel that might cause the rover to shift if the robotic arm is pressed against the surface target for a Rock Abrasion Tool (RAT) brush. So, a basic set of Microscopic Imager (MI) mosaics and an Alpha Particle X-ray Spectrometer (APXS) was performed without surface contact. Then a RAT preload test was done to see if the rover moved at all. Since no movement was observed, it was judged that the rover was stable enough to proceed with a RAT brush on Sol 3812 (Oct. 14, 2014).

That morning another comet imaging test was performed as a 'dress rehearsal' for the actual observations one week later. After the successful brush on Sol 3812, another MI mosaic was collected and the APXS was placed for a multi-sol integration. Another 'amnesia' event occurred on the evening of Sol 3812, however it was benign to rover operations. The rover is otherwise in good health.

As of Sol 3812 (Oct. 14, 2014), the solar array energy production was 605 watt-hours with a slightly elevated atmospheric opacity (Tau) of 1.19 and a solar array dust factor of 0.763.

Total odometry is 25.34 miles (40.78 kilometers).
