Opportunity Status at end of sol 144-149

While Opportunity is hard at work inside "Endurance Crater," engineers at JPL are busy testing engineering models in the Lab's simulated martian environment. A tilt platform is being used to determine Opportunity's ability to climb back up over the "curb" below its current location.

On sol 144, Opportunity completed the Moessbauer spectrometer integration on the rock abrasion tool hole on the "Cobble Hill" area. Microscopic images were also collected.

Sol 145 was a busy day, with the rover collecting more post-rock abrasion tool Cobble Hill and pre-"Virginia" microscopic images. The tool then bored a 4.3-millimeter (0.17 inches) hole in Virginia. Deep sleep mode was invoked for the overnight hours.

Sol 146 was used to examine the newly-abraded hole with the microscopic imager and the alpha particle X-ray spectrometer.

On sol 147 the rover performed a long Moessbauer spectrometer integration on Virginia and completed some remote sensing from its location in the crater. After relaying the data through both Mars Global Surveyor and Mars Odyssey, Opportunity went into deep sleep mode for the night.

"London" was Opportunity's target on sol 148. The rock abrasion tool ground a 4.5-millimeter (0.18 inches) hole in the rock. The alpha particle X-ray spectrometer was then placed on the hole for integration.

On sol 149 the rover continued to scrutinize London with the alpha particle X-ray spectrometer and the microscopic imager. A Moessbauer spectrometer integration was initiated and will be completed on sol 150. Deep sleep mode was invoked for the overnight hours.
