SPIRIT UPDATE: Spirit Remains Silent at Troy - sols 2594-2601,
April 21-28, 2011:

No communication has been received from Spirit since Sol 2210 (March 22,
2010).

Deep Space Network X-band listening and commanding covering a range of
frequencies and local solar times on Mars is continuing. Selected over
flights by the relay orbiters are exercised to elicit a response from
the rover through the separate ultra-high frequency (UHF) system.

Total odometry is unchanged at 7,730.50 meters (4.80 miles).

OPPORTUNITY UPDATE: Opportunity Makes Three Drives This Week -
sols 2573-2580, April 20-27, 2011:

Opportunity continues the trek towards Endeavour crater.

The rover drove on Sols 2574, 2576 and 2579 (April 21, 23 and 26, 2011),
covering over 340 meters (1,115 feet) to the southeast. The rover's
right front wheel motor currents have settled down some, but the project
continues to monitor this. The plan ahead is more driving.

As of Sol 2580 (April 27, 2011), solar array energy production was 381
watt-hours with an elevated atmospheric opacity (Tau) of 0.870 and a
solar array dust factor of 0.507.

Total odometry is 28,384.22 meters (28.38 kilometers, or 17.64 miles).
