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:  Rock Studies Continue for Opportunity - sols 2860-2865, February 09-14, 2012:

Opportunity is positioned on the north end of Cape York on the rim of Endeavour Crater with an approximate 15-degree northerly tilt for favorable solar energy production.

While positioned for the winter, Opportunity is conducting regular radio Doppler tracking measurements to support geo-dynamic investigations of the planet, in-situ (contact) science investigations of the rock target, "Amboy," including an extended Microscopic Imager mosaic, and continued collection of the 13-filter (stereo) 360-degree "Greeley" panorama. The Mössbauer spectrometer is currently on the surface target Amboy and is collecting a very long, (multi-sol) integration. Radio Doppler tracking passes were performed on Sols 2861 (Feb. 10, 2012) and 2863 (Feb. 12, 2012). More segments of the Greeley panorama were collected.

As of Sol 2865 (Feb. 14, 2012), solar array energy production was 274 watt-hours with an atmospheric opacity (Tau) of 0.678 and a solar array dust factor of 0.467.

Total odometry is unchanged at 21.35 miles (34,361.37 meters).
