USGS Completes Decommissioning of Landsat 5

 

On June 5, 2013, the U.S. Geological Survey Flight Operations Team transmitted the last command to the Landsat 5 satellite, effectively terminating the mission 29 years, 3 months and 4 days after its launch by NASA from Vandenberg Air Force Base on March 1, 1984. The Landsat program is a joint effort between USGS and NASA.                                     

 

Landsat 5 had orbited the planet over 150,000 times while transmitting over 2.5 million images of land surface conditions around the world, long outliving its original three-year design life. In December 2012, USGS announced that Landsat 5 would be decommissioned.  The durable satellite is recognized by the Guinness Book of Records as the longest-operating Earth-observing satellite mission in history. 

 

Landsat 5 beamed its last image down to the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD, on January 6, 2013. Nine days later, Mission Operations began the methodical process of maneuvering the satellite from its 438 mile-high operational orbit into a lower disposal orbit. With Landsat 5's fuel reserve completely depleted, the Operations team issued commands on June 5 to shut off all moving mechanisms and hobble the spacecraft’s ability to generate and store power from its solar arrays.  The final command shut down Landsat 5’s transmitter, silencing the mission permanently.

Really sad. Landsat 5 was a great satellite. Hopefully Landsat 8 will have a long and productive life
