Opportunity Status at end of sol 90 and 91

With 811.57 meters (a little over one half of one mile) on its odometer, 12,429 images downloaded and a record for the longest one-sol drive under its belt, Opportunity completed its prime mission. Finishing 90 sols of surface operations since landing day marked completion of the last of the official success criteria for Opportunity's prime mission.

On sol 90, the rover continued with the multi-sol panoramic camera and miniature thermal emission plains photometry observations. The alpha particle X-ray spectrometer was busy collecting data on the soil targets "Nougat" and "Fred Ripple."

On sol 91, Opportunity completed more remote sensing and took a Moessbauer spectrometer read on Fred Ripple. The rest of the sol was spent driving. A 40-meter (131.2 feet) drive in the southeasterly direction left Opportunity only 160 meters (about 525 feet) from the rim of "Endurance Crater."
