Spirit Rover Update
4 Dec 2006
- sol 1017-1023, December 04, 2006:
Spirit is healthy. Downlink of information from the rover resumed after a 48-hour gap in downlink that resulted from NASA's Mars Odyssey releasing most of its Deep Space Network coverage earlier in the week to Mars Global Surveyor to support efforts to recover communications with Global Surveyor.
This week, Spirit changed robotic-arm targets from "Berkner Island" to "Bear Island" and executed a microscopic image mosaic, five hours of data collection with the alpha particle X-ray spectrometer and nearly 48 hours with the M?ssbauer spectrometer. The engineering team planned and commanded Spirit's second drive of the season on sol 1022.
Sol 1017 (Nov. 12, 2006): Spirit used its microscopic imager to take exposures for a stereo mosaic of target Bear Island, then placed the alpha particle X-ray spectrometer on that target. After the Mars Odyssey pass, the rover took a tau (atmospheric clarity) measurement and then began a five-hour reading with the alpha particle X-ray spectrometer.
Sol 1018: The panoramic camera took thumbnail images of the sky, and the navigation camera scanned for clouds. The team changed tools to the M?ssbauer spectrometer and used it for a 10-hour integration on Bear Island.
Sol 1019: In the morning, the miniature thermal emission spectrometer assessed the sky and ground, and the panoramic camera examined the sky. The miniature thermal emission spectrometer then stared at target "Baudoin." Some engineering maintenance was done and then the M?ssbauer spectrometer was restarted on target Bear Island.
Sol 1020: In the morning, the miniature thermal emission spectrometer assessed the sky and ground, and the panoramic camera examined the sky. The rover restarted the M?ssbauer data-collection on Bear Island for a 23-hour, overnight integration.
Sol 1021: Spirit's miniature thermal emission spectrometer assessed light-toned material in the rover's tracks in the morning. The M?ssbauer spectrometer was restarted on Bear Island. The panoramic camera conducted a light experiment by taking multiple images throughout the day. The miniature thermal emission spectrometer assessed target "Allan Hills" during the communications pass with Mars Odyssey. After the Odyssey pass, the M?ssbauer observation was completed and the panoramic camera took a tau measurement at sunset.
Sol 1022: Spirit's arm was stowed before the rover began a short drive to a nearby outcrop. After the drive the navigation and hazard avoidance cameras took images. A tau measurement was taken as well.
Sol 1023 (Nov. 28): The panoramic camera took images of targets "El Dorado" and "Prat" as well as thumbnail images of the sky. The miniature thermal emission spectrometer conducted a sky and ground observation.
As of sol 1023, Spirit's odometry is 6,877.63 meters (4.27 miles).
