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:  Several Drives This Week Put Opportunity Near Marathon Distance - sols 3909-3914, January 22, 2015-January 27, 2015:

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).
