Landsat 5 successfully set the new Guinness World Records title for 'Longest-operating Earth observation satellite’ as stated in an e-mail from Guinness World Records sent to NASA Goddard Space Flight Center in Greenbelt, Md. Outliving its three-year design life, Landsat 5 delivered high-quality, global data of Earth's land surface for 28 years and 10 months.
NASA launched Landsat 5 from Vandenberg Air Force base in Lompoc, Calif. on March 1, 1984. Landsat 5 was designed and built at the same time as Landsat 4 and carried the same two instruments: the Multispectral Scanner System (MSS) and the Thematic Mapper (TM).
Managed by the U.S. Geological Survey (USGS) as part of the Landsat Program, it completed over 150,000 orbits and sent back more than 2.5 million images of Earth’s surface. On Dec. 21, 2012 the USGS announced Landsat 5 would be decommissioned in the coming months after the failure of a redundant gyroscope. The satellite carries three gyroscopes for attitude control and needs two to maintain control.
