Pasadena CA (JPL) Jun 21, 2010 Opportunity is driving again and has now covered 21 kilometers (13 miles) of odometry on Mars. The pancam mast assembly (PMA) azimuth error from Sol 2257 (May 30, 2010), has been attributed to a problem within the miniature thermal emission spectrometer (Mini-TES) instrument. An investigation of the Mini-TES is ongoing. The PMA has been restored to operation for imaging (not Mini-TES use). On Sol 2267 (June 10, 2010), a quick fine attitude (QFA) was performed to refine the rover's attitude knowledge and to correct for gyro drift. Additional drive direction imagery was also collected. On Sol 2270 (June 13, 2010), Opportunity drove for the first time since the PMA anomaly, covering over 70 meters (230 feet). The rover drove again on Sol 2272 (June 15, 2010), achieving almost 72 meters (236 feet) of distance to the east. As of Sol 2272 (June 15, 2010), solar array energy production was 297 watt-hours, atmospheric opacity (Tau) was 0.280 and the solar array dust factor is 0.570. Total odometry is 21,005.47 meters (21.00 kilometers, or 13.05 miles).

Spirit Catching More RaysPasadena CA (JPL) Jun 21, 2010 Spirit remains silent at her location called "Troy" on the west side of Home Plate. No communication has been received from the rover since Sol 2210 (March 22, 2010). It is likely that Spirit has experienced a low-power fault and has turned off all sub-systems, including communication and gone into a deep sleep. While sleeping, the rover will use the available solar array energy to recharg ... read more |
