sols 2690-2696, August 18-24, 2011 Opportunity Studies Rocks on Crater Rim
Opportunity has begun the in-situ (contact) investigation of rocks around the rim of Endeavour crater.
On Sol 2690 (Aug. 18, 2011), the rover began the approach to a large ejecta block, named "Tinsdale 2" with a 4-meter (13-foot) drive. On Sol 2692 (Aug. 20, 2011), Opportunity completed the approach to Tinsdale 2 with a turn-around to face the rock and a short 2-meter (7-foot) forward approach to the target. On Sol 2694 (Aug. 22, 2011), Opportunity started the multi-sol, multi-target in-situ (contact) investigation with a Microscopic Imager (MI) mosaic of a set of surface targets collectively named "Timmins," followed by a placement of the Alpha Particle X-ray Spectrometer (APXS) for an overnight integration. On Sol 2695 (Aug. 23, 2011), the rover collected another MI mosaic on a different target spot, again followed by an overnight APXS integration. On Sol 2696 (Aug. 24, 2011), Opportunity did it again with another set of MI mosaics and an APXS integration.
