GOES-17 (designated pre-launch as GOES-S) is an environmental satellite operated by the National Oceanic and Atmospheric Administration (NOAA). The satellite is second in the four-satellite GOES-R series (GOES-16, -17, -T, and -U). GOES-17 supports the Geostationary Operational Environmental Satellite (GOES) system, providing multi-spectral imaging for weather forecasts and meteorological and environmental research. The satellite was built by Lockheed Martin, based on the A2100A platform, and expected to have a useful life of 15 years (10 years operational after five years of standby as an on-orbit replacement). [6] GOES-17 is intended to deliver high-resolution visible and infrared imagery and lightning observations of more than half the globe. [7]
The satellite was launched on 1 March 2018 [2] and reached geostationary orbit on 12 March 2018. [8] In May 2018, during the satellite's testing phase after launch, a problem was discovered with its primary instrument, the Advanced Baseline Imager (see Malfunctions, below). [9] [10] GOES-17 became operational as GOES-West on 12 February 2019. [4] In June 2021, NOAA announced that due to the cooling problem with the satellite's main imager, GOES-T would replace the GOES-17 in an operational role "as soon as possible". [11] GOES-T launched on March 1, 2022. [12] [13]
The satellite was launched into space on 1 March 2018 by an Atlas V (541) launch vehicle from Cape Canaveral Air Force Station, Florida. [2] It had a launch mass of 5,192 kg (11,446 lb). [2] [14] On 12 March 2019, GOES-17 joined GOES-16 (launched in 2016) in geostationary orbit at 35,700 km (22,200 mi) above Earth. [8]
On 24 October 2018, GOES-17 began a 20-day, 2.5°/day westward drift maneuver from its checkout position of 89.5° West longitude to its operational position of 137.2° West. During the drift maneuver, all instruments except for the magnetometer were disabled. Meanwhile, GOES-15 began an eastward drift maneuver on 29 October 2018 to 128° West, with all of its sensors still functioning. It reached its new location on 7 November 2018. GOES-17 began transmitting its first images on 13 November 2018. The first high-definition images transmitted were of Alaska, Hawaii, and the Pacific Ocean. [15] GOES-15's drift was intended to provide additional separation from GOES-17 to prevent communication interference. GOES-17 reached its assigned longitude 13 November 2018 and began additional testing. [5] GOES-17 was declared operational on 12 February 2019. Both GOES-17 and GOES-15 operated in tandem through early 2020 to allow assessment of GOES-17's performance as GOES-West. [16] On 2 March 2020, GOES-15 was deactivated and moved to a storage orbit, with plans to re-activate it in August 2020 supplement GOES-17 operations due to the known flaws with the Advanced Baseline Imager. [17] [18]
On 23 May 2018, NOAA announced that there were problems with the cooling system of the Advanced Baseline Imager. [9] [10] Due to the cooling failure, infrared and near-infrared imaging was only possible 12 hours per day. The issue affects 13 of the infrared and near-infrared channels on the instrument. No other sensors of the satellite are affected.
During a media conference call on 24 July 2018, [19] the problem component was identified as the loop heat pipe, which transports heat from the cryocooler and ABI to radiators. [20] The degraded performance of this component means the ABI gets hotter than intended, which lowers the sensitivity of the infrared sensors. In order to work properly, the sensors need to be cooled to varying degrees depending on what wavelength they observe; the sensors operating in the longest wavelengths need to be kept as low as −212.8 °C (−351.0 °F; 60.3 K) in order to reduce thermal noise. [nb 1]
The GOES-R System program director, Pam Sullivan, [21] said on the conference call that preliminary projections suggested that via thermal mitigation measures such as changing the spacecraft alignment, ABI performance could be significantly improved, depending on the season. The orbit of the spacecraft brings the ABI into full sunlight more often around the equinoxes, resulting in more solar radiation being absorbed by the ABI and degrading the performance of the infrared channels, with projections indicating that 10 of the 16 channels will be available 24 hours a day, with the other six channels available for "most of the day, to varying degrees, depending on their wavelength. [19] Around the solstices, the orbit alignment is such that the ABI receives less direct sunlight, and it is projected that 13 of the 16 channels will be available 24 hours a day with the other three channels available 20 or more hours per day.
The loop heat pipe (LHP) was manufactured by Orbital ATK (now owned by Northrop Grumman). On 2 October 2018, NOAA and NASA appointed a five-member Mishap Investigation Board to further examine the issue. [22] NOAA worked with Northrop Grumman to identify exactly what caused the loop heat pipe to fail, using engineering-grade copies of the spacecraft components for testing. [19] Possible causes mentioned in the conference call included debris or foreign objects inside the heat pipe, or an improper amount of propylene coolant. The final conclusion of the independent failure review team's investigation, released on 3 October 2018, was that "the most likely cause of the thermal performance issue is foreign object debris (FOD) blocking the flow of the coolant in the loop heat pipes. A series of ground-based tests introducing FOD into test pipes support FOD as the most likely cause. A second potential cause, mechanical failure, was investigated and deemed unlikely. The failure review team recommended changes to the ABI radiators on the subsequent GOES-R Series satellites, including a simpler hardware configuration and the use of ammonia as the coolant rather than propylene. The system was redesigned, and a Critical Design Review (CDR), originally scheduled for December 2018 but delayed as a result of a government shutdown, was eventually held on 7–8 February 2019. [16]
Various software workarounds were introduced in order to minimize the impact of the loop heat pipe (LHP) problem on GOES-17.
In October 2018, Lockheed Martin finished assembling the next unit of the GOES-R series, GOES-T, and was preparing to begin environmental testing of the completed satellite, when NOAA ordered the removal of the ABI to return to the manufacturer, Harris Corporation, for remanufacturing. [23] [nb 2] As a result, the scheduled May 2020 launch of GOES-T was delayed [23] [24] until March 1, 2022. [25] The 2024 launch of GOES-U will probably not be delayed as a result of the redesign. [19]
On 20 November 2018, a memory error occurred in the ABI which resulted from a software update for its cryocooler subsystem. This resulted in automated onboard safety checks shutting down the cryocooler. It was restored to operation on 25 November 2018, and engineers began working on a permanent software fix for deployment in January 2019. [26] [27]
On 15 August 2019, GOES-17 experienced a brief "spacecraft anomaly" from about 13:45 to 17:00 UTC. This anomaly prevented delivery of all bands and scenes. [28]
NOAA's GOES-R Series of satellites is designed to improve the forecasts of weather, ocean, and environment by providing faster and more detailed data, real-time images of lightning, and advanced monitoring of solar activities and space weather. GOES-17 can collect three times more data at four times image resolution, and scan the planet five times faster than previous probes.
GOES-17 has the same instruments and capabilities as GOES-16 (currently serving as GOES-East), and will complement its work by scanning a different area of the world. GOES-17 is GOES-West when it moves to 137.2° West longitude and cover the west coast of the continental U.S., Hawaii, and much of the Pacific Ocean. These two satellites are expected to monitor most of the Western Hemisphere and detect natural phenomena and hazards in almost real time. [8] [29]
Its capabilities will allow better: [29]
Along with GOES-16, these newly advanced satellites can give near-real-time updates on what is happening in the atmosphere across the United States. [30]
The instrument suite of GOES-17 is identical to that of GOES-16. It includes: [31]
The Advanced Baseline Imager (ABI) was built by Harris Corporation [32] Space and Intelligence Systems (formerly ITT/Exelis) for the GOES-R line of satellites for imaging Earth's weather, climate and environment. Key subcontractors for the ABI instrument included BAE Systems, Babcock Incorporated, BEI Technologies, DRS Technologies, L-3 Communications SSG-Tinsley and Northrop Grumman Space Technology, and Orbital ATK. [33] The imaging capabilities of the ABI are superior to previous imagers in several ways.
This instrument has 16 bands (11 more than the last GOES imager: [34] )
2 Visible Bands:
4 Near IR Bands:
10 other Infrared Bands:
The temporal resolution of ABI products changes depending on the type of image:
Spatial resolution will be dependent on what band is being used - band 2 is the highest resolution out of all channels, with a resolution of 500 m (1,600 ft). Channels 1, 3, and 5 will have a resolution of 1 km (0.6 mi), while all other bands in NIR/IR will have a resolution of 2 km (1.2 mi). [35]
The Geostationary Lightning Mapper (GLM) is used for measuring lightning (in-cloud and cloud-to-ground) activity. To do this, it considers a single channel in the NIR (777.4-nm) constantly, even during the day, to catch flashes from lightning.
The sensor has a 1372 × 1300 pixel CCD, with an 8–14 km (5.0–8.7 mi) spatial resolution (with the resolution decreasing near the edges of the field of view (FOV). The GLM has a frame interval of 2 milliseconds, meaning it considers the entire study area 500 times every second. [36]
Development of the GLM was contracted to the Lockheed Martin Advanced Technology Center in Palo Alto, California. [37]
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.
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites are mainly of two types: polar orbiting or geostationary.
Deep Space Climate Observatory is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. This is NOAA's first operational deep space satellite and became its primary system of warning Earth in the event of solar magnetic storms.
NOAA-17, also known as NOAA-M before launch, was an operational, polar orbiting, weather satellite series operated by the National Environmental Satellite Service (NESS) of the National Oceanic and Atmospheric Administration (NOAA). NOAA-17 also continued the series of Advanced TIROS-N (ATN) spacecraft begun with the launch of NOAA-8 (NOAA-E) in 1983 but with additional new and improved instrumentation over the NOAA A-L series and a new launch vehicle.
NOAA-16, also known as NOAA-L before launch, was an operational, polar orbiting, weather satellite series operated by the National Environmental Satellite Service (NESS) of the National Oceanic and Atmospheric Administration (NOAA). NOAA-16 continued the series of Advanced TIROS-N (ATN) spacecraft that began with the launch of NOAA-8 (NOAA-E) in 1983; but it had additional new and improved instrumentation over the NOAA A-K series and a new launch vehicle. It was launched on 21 September 2000 and, following an unknown anomaly, it was decommissioned on 9 June 2014. In November 2015 it broke up in orbit, creating more than 200 pieces of debris.
NOAA-18, also known as NOAA-N before launch, is an operational, polar orbiting, weather satellite series operated by the National Environmental Satellite Service (NESS) of the National Oceanic and Atmospheric Administration (NOAA). NOAA-18 also continued the series of Advanced TIROS-N (ATN) spacecraft begun with the launch of NOAA-8 (NOAA-E) in 1983 but with additional new and improved instrumentation over the NOAA A-M series and a new launch vehicle. NOAA-18 is in an afternoon equator-crossing orbit and replaced NOAA-17 as the prime afternoon spacecraft.
NOAA-15, also known as NOAA-K before launch, is an operational, polar-orbiting of the NASA-provided Television Infrared Observation Satellite (TIROS) series of weather forecasting satellite operated by National Oceanic and Atmospheric Administration (NOAA). NOAA-15 was the latest in the Advanced TIROS-N (ATN) series. It provided support to environmental monitoring by complementing the NOAA/NESS Geostationary Operational Environmental Satellite program (GOES).
Landsat 8 is an American Earth observation satellite launched on 11 February 2013. It is the eighth satellite in the Landsat program; the seventh to reach orbit successfully. Originally called the Landsat Data Continuity Mission (LDCM), it is a collaboration between NASA and the United States Geological Survey (USGS). NASA Goddard Space Flight Center in Greenbelt, Maryland, provided development, mission systems engineering, and acquisition of the launch vehicle while the USGS provided for development of the ground systems and will conduct on-going mission operations. It comprises the camera of the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS), which can be used to study Earth surface temperature and is used to study global warming.
The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting. The spacecraft were provided by NASA and the European Space Agency (ESA), and NASA's Goddard Space Flight Center oversaw the manufacture, integration and test of the NASA-provided TIROS satellites. The first polar-orbiting weather satellite launched as part of the POES constellation was the Television Infrared Observation Satellite-N (TIROS-N), which was launched on 13 October 1978. The final spacecraft, NOAA-19, was launched on 6 February 2009. The ESA-provided MetOp satellite operated by EUMETSAT utilize POES-heritage instruments for the purpose of data continuity. The Joint Polar Satellite System, which was launched on 18 November 2017, is the successor to the POES Program.
NOAA-13, also known as NOAA-I before launch, was an American weather satellite operated by the National Oceanic and Atmospheric Administration (NOAA). NOAA-I continued the operational, polar orbiting, meteorological satellite series operated by the National Environmental Satellite System (NESS) of the National Oceanic and Atmospheric Administration (NOAA). NOAA-I continued the series (fifth) of Advanced TIROS-N (ATN) spacecraft begun with the launch of NOAA-8 (NOAA-E) in 1983. NOAA-I was in an afternoon equator-crossing orbit and was intended to replace the NOAA-11 (NOAA-H) as the prime afternoon (14:00) spacecraft.
NOAA-7, known as NOAA-C before launch, was an American operational weather satellite for use in the National Operational Environmental Satellite System (NOESS) and for the support of the Global Atmospheric Research Program (GARP) during 1978-1984. The satellite design provided an economical and stable Sun-synchronous platform for advanced operational instruments to measure the atmosphere of Earth, its surface and cloud cover, and the near-space environment. An earlier launch, NOAA-B, was scheduled to become NOAA-7, however NOAA-B failed to reach its required orbit.
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.
NOAA-6, known as NOAA-A before launch, was an American operational weather satellite for use in the National Operational Environmental Satellite System (NOESS) and for the support of the Global Atmospheric Research Program (GARP) during 1978–1984.

GOES-16, formerly known as GOES-R before reaching geostationary orbit, is the first of the GOES-R series of Geostationary Operational Environmental Satellites (GOES) operated by NASA and the National Oceanic and Atmospheric Administration (NOAA). GOES-16 serves as the operational geostationary weather satellite in the GOES East position at 75.2°W, providing a view centered on the Americas. GOES-16 provides high spatial and temporal resolution imagery of the Earth through 16 spectral bands at visible and infrared wavelengths using its Advanced Baseline Imager (ABI). GOES-16's Geostationary Lightning Mapper (GLM) is the first operational lightning mapper flown in geostationary orbit. The spacecraft also includes four other scientific instruments for monitoring space weather and the Sun.
GOES-18 is the third of the "GOES-R Series", the current generation of weather satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The current and next satellites of the Series will extend the availability of the Geostationary Operational Environmental Satellite (GOES) satellite system until 2037. The satellite is built by Lockheed Martin in Littleton, Colorado. It is based on the A2100A satellite bus and will have an expected useful life of 15 years.
NOAA-21, designated JPSS-2 prior to launch, is the second satellite in National Oceanic and Atmospheric Administration (NOAA)'s latest series of U.S. polar-orbiting, non-geosynchronous, environmental satellites, known as the Joint Polar Satellite System (JPSS). Launched on November 10, 2022, along with LOFTID, NOAA-21 now operates in the same orbit as NOAA-20 and Suomi NPP. It travels in a polar orbit, crossing the equator approximately 14 times a daily, and provides complete global coverage twice a day.
