The USGS is pleased to announce that Landsat 5 tested imaging with the Thematic Mapper on January 10, 2008 during a pass over Brazil and Argentina. Landsat 5 imaging was suspended on October 6, 2007 due to a loss of a cell within one of two batteries. The Landsat Flight Operations Team has determined the status of the power system and potential solutions for maximum imaging operations. We are still in a testing phase, as the new battery configuration is being characterized. Experts in Thematic Mapper data have determined that the sensor is operating normally. We expect to return to a new operational state in upcoming weeks.
