OPPORTUNITY UPDATE: Investigating Light-toned Veins in Rock Outcrop -
sols 3187-3193, Jan. 10, 2013-Jan. 16, 2013:

Opportunity is on the inboard edge of "Cape York" on the rim of Endeavour
Crater, now engaged in in-situ (contact) science investigation of veins
in the light-toned outcrop "Whitewater Lake," a place the rover visited
previously.

On Sol 3187 (Jan. 10, 2013), the rover bumped a little over a meter to
reach the vein targets in the outcrop, named "Ortiz." On Sol 3189
(Jan. 12, 2013), Opportunity, using her robotic arm, collected a large
Microscopic Imager (MI) mosaic of the vein targets. This was followed by
the placement of the Alpha Particle X-ray Spectrometer (APXS) for an
overnight integration. On Sol 3191 (Jan. 14, 2013), the rover collected
more MI mosaics of a target offset from the first and completed this
with placing the APXS on the new target.

Opportunity started exhibiting memory symptoms this month similar to
events seen with Spirit in 2009. This is not a health and safety concern,
but can cause loss of some data intended for downlink. It can be avoided
for more important data by downlinking before any rover nap. The suspect
cause is corruption in the flash file system used by the rover for
non-volatile telemetry storage. The project implemented a detection
diagnostic on Sol 3189 (Jan. 12, 2013) to flag the occurrence of these
events in separate non-volatile memory. No events have occurred since
Sol 3183 (Jan. 6, 2013), and the rover remains in good health.

As of Sol 3193 (Jan. 16, 2013), the solar array energy production was
498 watt-hours with an atmospheric opacity (Tau) of 1.08 and a solar
array dust factor of 0.623.

Total odometry is 22.03 miles (35455.34 meters).
