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:  Ground Control Restored Quickly After Reset - sols 3745-3751, August 06, 2014-August 12, 2014:

Opportunity is moving south along the west rim of Endeavour Crater heading towards "Marathon Valley," a putative location for abundant clay minerals.

On Sol 3746 (Aug. 7, 2014), the rover began with a Phobos moon transit observation, then a 236-foot (72-meter) drive south towards a formation, called "Wdowiak Ridge." On the evening of that sol, Opportunity experienced a Flash-induced reset that stopped all sequences, but otherwise left the rover in good health.

At the start of the next plan, the project commanded a real-time activate for Opportunity to restore sequence control and to execute the next plan, a 2-sol "touch 'n go." On Sol 3748 (Aug. 9, 2014), Opportunity used the robotic arm to collect a Microscopic Imager mosaic of a target of opportunity called "Icy Straight." This was followed by the placement of the Alpha Particle X-ray Spectrometer on the same surface target for a multi-hour integration ("the touch"). Then, on Sol 3749 (Aug. 10, 2014), the rover drove over 328 feet (100 meters) ("the go"), including some mid-drive imaging. Keeping up the pace, the rover continued driving south towards Wdowiak Ridge on the next two sols with drives of 183 feet and 108 feet (56 meters and 33 meters), respectively.

As of Sol 3751 (Aug. 12, 2014), the solar array energy production was 679 watt-hours with an atmospheric opacity (Tau) of 0.811 and a solar array dust factor of 0.789.

Total odometry is 25.25 (40.63 kilometers).
