Rover begins contact science of rock target on Knudsen Ridge

Opportunity is exploring 'Marathon Valley' on the rim of Endeavour crater.

The rover is up on the very steep slopes of 'Knudsen Ridge.'

Opportunity has begun the in-situ (contact) investigation of the current site. On Sol 4291 (Feb. 18, 2016), the rover bumped about 27 inches (68 centimeters) towards the first surface target, called 'Charles Caugee' (named for a member of the Corps of Discovery).

After the successful bump, more documentary imagery was collected using both the Panoramic Camera (Pancam) and Navigation Camera (Navcam).

Then, on Sol 4295 (Feb. 22, 2016), the robotic arm was used to collect a detailed Microscopic Imager (MI) mosaic.

The plan ahead is to place the Alpha Particle X-ray Spectrometer (APXS) to collect elemental information about this target.

As of Sol 4296 (Feb. 23, 2016), the solar array energy production was 543 watt-hours with an atmospheric opacity (Tau) of 0.409 and a solar array dust factor of 0.707.

Total odometry is 26.51 miles (42.66 kilometers), more than a marathon

Opportunity Mars Rover Goes Six-Wheeling up a Ridge
Pasadena CA (JPL) Feb 26, 2016
NASA's senior Mars rover, Opportunity, is working adeptly in some of the most challenging terrain of the vehicle's 12 years on Mars, on a slope of about 30 degrees. Researchers are using Opportunity this month to examine rocks that may have been chemically altered by water billions of years ago. The mission's current targets of investigation are from ruddy-tinted swaths the researchers call "red ... read more
