Mars Exploration Rover Update - August 23, 2007

OPPORTUNITY UPDATE: Brightening Skies Bolster Opportunity - sol 1256-1265, Aug 23, 2007:

Opportunity is healthy and remains perched near the rim of “Victoria Crater.” The rover was on a low-power schedule that alternated between a 3-sol plan and a 4-sol plan.

Tau (atmospheric opacity) has begun to stabilize this week at around 3.7, resulting in solar array energy between 230-240 watt hours. Therefore in the upcoming week, the team will return to nominal planning.

The rover conducted a lot of what engineers call “runout science.” This includes: panoramic camera wide-range tau measurements, navigation camera tau measurements, navigation camera cloud measurements, panoramic camera soria (imaging a rough, rocky area near the rover), front hazard avoidance camera images, rear hazard avoidance camera images, navigation camera images, panoramic camera sky spot, panoramic camera dust monitoring on the mast, miniature thermal emission spectrometer target calibration and panoramic camera high-sun surveys.

Sol-by-sol summary:

Sol 1256: Opportunity conducted one hour of runout science.

Sol 1257: On this sol, the rover’s activities included the following: uplinked on high-gain antenna, panoramic camera wide-range tau, navigation camera tau, navigation camera bitty cloud, panoramic camera soria, front hazard avoidance camera images, rear hazard avoidance camera images, navigation camera images, panoramic camera wide-range tau, panoramic camera horizon survey, panoramic camera calibration target, mast dust monitoring, miniature thermal emission spectrometer calibration target and panamoric camera high-sun survey.
