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:  A New Year Yields Interesting Bright Soil - sols 4590-4602, December 22, 2016 January 03, 2017:

Opportunity is located on the rim of Endeavour crater, heading south along the rim.  The near-term plan is to reach a valley called "Willamette" where grooves are seen in orbital imagery.  Just before the holidays, the rover encountered some difficult, steep terrain.  As the rover tried to advance up 20-degree slopes, the wheels began to dig up the soil and progress slowed to a near stop.  Sensing this, the rover stopped her drive and waited.  So, on Sol 4590 (Dec. 22, 2016), the team had Opportunity back down a short, 2-foot (70-cm) distance to put the rover on a more solid footing.  

Before we could continue with rover activities through the holidays, Mars Odyssey went into “safe mode,” an event that prevented relay data return from Opportunity.  The rover was patient for several sols and in good health.  With Odyssey back, on Sol 4601 (January 2, 2017) Opportunity moved another 6.6 feet (2 meters) to get a good look of the terrain that was disturbed during the up-hill driving challenge.  The disturbed soil reveals brightly colored, unconsolidated material that is of great interest to the science team.  So, the plan ahead is to use the rover's robotic arm instruments to investigate this bright soil.  

As of Sol 4602, (January 3, 2017) the solar array energy production is 520 watt-hours with an atmospheric opacity (Tau) of 0.752 and a solar array dust factor of 0.683.

Total odometry is 27.17 miles (43.74 kilometers).
