Spirit has completed investigations with its robotic arm on "Assemblee" rock. The investigation included pictures taken with the microscopic imager, 92 hours of Moessbauer spectrometer integration, and alpha particle X-ray spectrometer work on the target "Gruyere."
Other observations included dust devil movies and a panoramic camera image of the rock abrasion tool bit (which has worn down from extensive use because Spirit has exceeded its intended lifespan by more than 480 sols).
As of sol 571 (Aug. 11, 2005), Spirit is still approximately 100 meters (328 feet) from the summit, and the rover will continue driving towards it.
Sol 565 (Aug. 5, 2005): Spirit took a picture of the bit on the rock abrasion tool and drove 2.35 meters (7.71 feet) to Assemblee.
Sol 566: Spirit did remote sensing and used the microscopic imager and alpha particle X-ray spectrometer to investigate Gruyere on Assemblee.
Sol 567: Spirit used the Moessbauer spectrometer on Assemblee for 23 hours and 5 minutes. Spirit also performed targeted remote sensing, including miniature thermal emission spectrometer stares on four targets and imaging with the panoramic camera.
Sol 568: Spirit took another Moessbauer spectrometer reading on Assemblee for 23 hours and 5 minutes. It also completed panoramic camera imaging with 13 filters on four targets, and it took a dust devil movie.
Sol 569 and 570: Spirit took more Moessbauer spectrometer readings on Assemblee and performed remote sensing.
Sol 571 (Aug. 11, 2005): Spirit used the alpha particle X-ray spectrometer and microscopic imager on two targets on Assemblee.
As of the end of its 571st sol on Mars, Spirit has driven 4,691 meters (2.91 miles).

Opportunity Parks Itself In Front Of A Field Of "Cobbles"

Pasadena CA (JPL) Aug 15, 2005
After months of being the "other rover" as she struggled across some pretty barren plains of sand and blueberries, Opportunity has again taken center stage. One of the things we've been wondering about for awhile was whether the blueberries are the same everywhere, or whether they change from place to place if you travel far enough.
