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:  Opportunity Nears Crater Rim - sols 2641-2647, June 29-July 5, 2011:

Opportunity is now within 2 kilometers (1.2 miles) of the first landfall on the rim of Endeavour crater, at a place called "Spirit Point."

With multi-sol planning for the 4th of July holiday weekend, the rover drove only once in the past week with a drive to the southeast on Sol 2645 (July 3, 2011), of over 162 meters (531 feet). On Sol 2642 (June 30, 2011), the Alpha Particle X-ray Spectrometer (APXS) performed another atmospheric argon measurement. On the next sol, a forward link ultra-high frequency (UHF) test was conducted with the Mars Reconnaissance Orbiter.

As of Sol 2647 (July 5, 2011), solar array energy production was 421 watt-hours with an atmospheric opacity (Tau) of 1.03 and a solar array dust factor of 0.596.

Total odometry is 31,630.68 meters (31.63 kilometers, or 19.66 miles).
