GOES-8, known as GOES-I before becoming operational, was an American weather satellite, which formed part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. It was launched in 1994, and operated until 2004 when it was retired and boosted to a graveyard orbit. [1] [2] At launch, the satellite had a mass of 2,105 kilograms (4,641 lb), and an expected operational lifespan of three or five years. [3] [4] It was built by Space Systems/Loral, based on the LS-1300 satellite bus, and was the first of five GOES-I series satellites to be launched.
GOES-I was launched aboard a Martin Marietta Atlas I rocket, flying from Launch Complex 36B at the Cape Canaveral Air Force Station. [5] The launch occurred at 06:04 GMT on 13 April 1994, [5] and placed the satellite into a geosynchronous transfer orbit. It was then raised into geostationary orbit by means of an R-4D-11 apogee motor. [3] During the first burn of the apogee motor, an unusually high temperature was detected in one of the flanges upon which a thruster was mounted, [6] however later analysis, based on satellites using similar thruster systems, demonstrated that it was still acceptable. [6] During the third burn, a malfunction of the computer controlling the attitude control system caused several manoeuvring thrusters to fire. This resulted in the burn being aborted. [6]
GOES-8 was eventually raised to the correct orbit, and positioned at a longitude of 75° West. [4] [7] Following on-orbit testing, it was activated as the GOES-EAST satellite, allowing GOES-7, which had previously been covering both positions, to assume GOES-WEST operations.
GOES-8 suffered from a design fault with the motor windings in its imager and sounder, with one of two sets failing within a few years of it becoming operational. If the other set had failed, it would have made the system inoperable. This fault also occurred on the GOES-9 satellite, which was launched in 1995. It was corrected before GOES-10 was launched. [8] In 1997, one of its momentum wheels failed, however unlike with GOES-9, the other wheel was not affected, and the satellite was able to continue operations. [4] GOES-8 was also featured in the 1996 film Twister .
GOES-8 was retired from GOES-EAST operations in 2003, when it was replaced by GOES-12. [9] Following this it remained in storage for a year as a backup, before being boosted to a graveyard orbit between 4 and 5 May 2004. [4]
The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research. Spacecraft and ground-based elements of the system work together to provide a continuous stream of environmental data. The National Weather Service (NWS) and the Meteorological Service of Canada use the GOES system for their North American weather monitoring and forecasting operations, and scientific researchers use the data to better understand land, atmosphere, ocean, and climate dynamics.
EWS-G1 is a weather satellite of the U.S. Space Force, formerly GOES-13 and part of the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. On 14 April 2010, GOES-13 became the operational weather satellite for GOES-East. It was replaced by GOES-16 on 18 December 2017 and on 8 January 2018 its instruments were shut off and it began its three-week drift to an on-orbit storage location at 60.0° West longitude, arriving on 31 January 2018. It remained there as a backup satellite in case one of the operational GOES satellites had a problem until early July 2019, when it started to drift westward and was being transferred to the U.S. Air Force, and then the U.S. Space Force.
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, 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. It remained at this post until it was decommissioned on August 16, 2013 and subsequently boosted to a graveyard orbit.
GOES-11, known as GOES-L 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 in 2000, and operated at the GOES-WEST position, providing coverage of the west coast of the United States, until December 6, 2011.
GOES-10, known as GOES-K before becoming operational, was an American weather satellite, which formed part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. It was launched in 1997, and after completing operations as part of the main GOES system, it was kept online as a backup spacecraft until December 2009, providing coverage of South America as GOES-SOUTH, and being used to assist with hurricane predictions for North America. It was retired and maneuvered to a graveyard orbit on 1 December 2009.
GOES-9, known as GOES-J before becoming operational, was an American weather satellite, which formed part of the U.S. National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. It was launched in 1995, and operated until 2007 when it was retired and boosted to a graveyard orbit. At launch, the satellite had a mass of 2,105 kilograms (4,641 lb), and an expected operational lifespan of three years. It was built by Space Systems/Loral, based on the LS-1300 satellite bus, and was the second of five GOES-I series satellites to be launched.
GOES-7, known as GOES-H before becoming operational, is an American satellite. It was originally built as a weather satellite, and formed part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. Originally built as a ground spare, GOES-H was launched in 1987 due to delays with the next series of satellites. It was operated by NOAA until 1999, before being leased to Peacesat, who use it as a communications satellite. As of 2009, it was operational over the Pacific Ocean, providing communications for the Pacific Islands. On April 12, 2012, the spacecraft was finally decommissioned and moved to a graveyard orbit.
