USGS Keeps Landsat 5 Satellite Alive

Geoplace.com, July 9, 2012

The U.S. Geological Survey (USGS) injected a bit of life into its aging Landsat 5 satellite, which has orbited Earth more than 150,000 times since its launch in 1984 and has been experiencing problems with its thematic mapper (TM) instrument. Engineers have been able to power-on a long-dormant data-collection instrument aboard the satellite—the multispectral scanner (MSS), which has been offline for more than a decade. USGS now is acquiring MSS data over the United States only. The news is significant, because USGS continues to work toward launch of an eighth Landsat satellite, meaning that data from current Landsat craft still are key to Earth-observing operations. Landsat 7, activated in 1999, continues to collect images worldwide. But, in 2003, Landsat 7 experienced a hardware failure that caused a 22-percent loss of data in every image. Meanwhile, the Landsat Data Continuity Mission (LDCM or Landsat 8), is scheduled for launch in January 2013.
