GOES-12, known as GOES-M before becoming operational, is an American weather satellite, which is part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. It was launched on July 23, 2001,[3] and spent its first 21 months in space as an on-orbit spare. From April 2003, the satellite took over the GOES-East position, providing coverage of the eastern half of the continental United States. In April 2010, GOES-East operations were taken over by GOES-13, and GOES-12 transitioned to the GOES-South location to devote time to South American imagery.[4] It remained at this post until it was decommissioned on August 16, 2013[3] and subsequently boosted to a graveyard orbit.
