Opportunity Targets Amboy Rock For Extra Study Ahead of Winter
by Staff Writers
Pasadena CA (JPL) Jan 16, 2012

Opportunity very much needs a spring clean from a passing dust devil.

Opportunity is positioned for winter on the north end of "Cape York" on the rim of Endeavour Crater.

The rover is tilted about 15 degrees to the north for favorable solar energy production. Opportunity is conducting in-situ (contact) science investigations of the rock target, "Amboy."

The Mossbauer spectrometer has been in place for several sols on Amboy. On Sol 2829 (Jan. 8, 2012), the Microscopic Imager was used to make additional surveys of the target with the Mossbauer being placed again on the same point.

After some image assessments, the robotic arm was used on Sol 2831 (Jan. 10, 2012), to slightly reposition the Mossbauer.

Ongoing with the long Mossbauer integrations, Opportunity has been conducting regular radio Doppler X-band tracking passes in support of an experiment to measure the precession and nutation of the planet.

Opportunity has also been collecting color Panoramic Camera (Pancam) images of the full 360-degree "Greeley" panorama from this site.

The plan ahead is more Mossbauer, more Pancam and more radio Doppler tracking.

As of Sol 2832 (Jan. 11, 2012), solar array energy production was 281 watt-hours with an atmospheric opacity (Tau) of 0.697 and a solar array dust factor of 0.471.

'Greeley Haven' is Winter Workplace for Mars Rover
Pasadena CA (JPL) Jan 10, 2012
NASA's Mars Exploration Rover Opportunity will spend the next several months at a site informally named "Greeley Haven." The name is a tribute to planetary geologist Ronald Greeley (1939-2011), who was a member of the science team for the Mars rovers and many other interplanetary missions. The site is an outcrop that provides a sun-facing slope to aid in maintaining adequate solar power du ... read more
