OPPORTUNITY UPDATE: Rover Completes Mini-Walkabout -
sols 4344-4350, April 13, 2016-April 19, 2016

Opportunity is exploring 'Marathon Valley' located on the rim of Endeavour
crater. The objective is to identify specific outcrops for evidence of
clay minerals.

Opportunity has completed a mini-'walkabout' with extensive imaging of
the region and is now beginning the in-situ (contact) investigation. On
Sol 4345 (April 14, 2016), the rover moved just about 8 feet (2.5 meters),
approaching a target for investigation with the robotic arm instruments.
On Sol 4347 (April 16, 2016), Opportunity used the robotic arm to collect
a Microscopic Imager (MI) mosaic of the surface target, named 'Pierre
Pinaut.' This was followed by the placement of the Alpha Particle X-ray
Spectrometer (APXS) on the same target for a multi-hour integration. In
between these activities, the rover continues to collect extensive Panoramic
Color (Pancam) color panoramas, Navigation Camera (Navcam) panoramas and
targeted multi-filter images.

On Sol 4350 (April 19, 2016), Opportunity attempted to collect additional
MI mosaics, but a goal error occurred because the first image with the
MI camera did not complete. This is an anomaly that has seen before where
a camera image fails to complete. The project is investigating this and
is preparing diagnostics to run on the camera system.

As of Sol 4350 (April 19, 2016), the solar array energy production is
635 watt-hours with an atmospheric opacity (Tau) of 0.461 and a solar
array dust factor of 0.762.

Total odometry is 26.58 miles (42.78 kilometers), more than a marathon
