NOAA's latest generation of geostationary weather satellites
The Geostationary Operational Environmental Satellite (GOES) – R Series is the nation’s most advanced fleet of geostationary weather satellites. The GOES-R Series significantly improves the detection and observation of environmental phenomena that directly affect public safety, protection of property and our nation’s economic health and prosperity.
The satellites provide advanced imaging with increased spatial resolution and faster coverage for more accurate forecasts, real-time mapping of lightning activity, and improved monitoring of solar activity and space weather.
The GOES-R Series is a four-satellite program (GOES-R/S/T/U) that will extend the availability of the operational GOES satellite system through 2036.
Remote environmental sensing is only part of the GOES-R Series mission. The satellites also provide unique capabilities to relay data directly to users to meet critical needs
DCS is a satellite relay system used to collect information from Earth-based data collection platforms that transmit in-situ environmental sensor data from more than 20,000 platforms across the hemisphere.
GOES Rebroadcast provides the primary relay of full resolution, calibrated, near-real-time direct broadcast space relay of Level 1b data from each instrument and Level 2 data from the Geostationary Lightning Mapper (GLM). GRB replaces the GOES VARiable (GVAR) service
The Emergency Managers Weather Information Network (EMWIN) is a direct service that provides users with weather forecasts, warnings, graphics and other information directly from the National Weather Service (NWS) in near real-time. The HRIT service is a new high data rate (400 Kpbs) version of the previous LRIT (Low Rate Information Transmission), broadcasting GOES-R Series satellite imagery and selected products to remotely-located user terminals.
The SARSAT system detects and locates mariners, aviators and other recreational users in distress. The GOES-R Series continues the legacy function of the SARSAT system on board NOAA’s GOES satellites. This system uses a network of satellites to quickly detect and locate signals from emergency beacons onboard aircraft, vessels and from handheld personal locator beacons. The GOES-R Series SARSAT transponder operates with a lower uplink power than the current system (32 bBm), enabling GOES-R Series satellites to detect weaker beacon signals.
The GOES-R series spacecraft bus is three-axis stabilized and designed for 10 years of on-orbit operation preceded by up to five years of on-orbit storage. The spacecraft carries three classifications of instruments: nadir-pointing, solar-pointing, and in-situ. Visit the Spacecraft page of this site for more information.

The most recent images of Earth's western hemisphere from the GOES constellation.
Environmental satellites provide data in several different formats. The most commonly used channels on weather satellites are the visible, infrared, and water vapor.
Visible satellite images, which look like black and white photographs, are derived from the satellite’s signals. Clouds usually appear white, while land and water surfaces appear in shades of gray or black. The visible channel reflects solar radiation. Clouds, the Earth's atmosphere, and the Earth's surface all absorb and reflect incoming solar radiation. Since visible imagery is produced by reflected sunlight (radiation), it is only available during daylight.
In the infrared (IR) channel, the satellite senses energy as heat. The Earth’s surface absorbs about half of the incoming solar energy. Clouds and the atmosphere absorb a much smaller amount. The Earth’s surface, clouds, and the atmosphere then re-emit part of this absorbed solar energy as heat. The infrared channel senses this re-emitted radiation. Infrared imagery is useful for determining cloud features both at day and night.
Water vapor imagery is used to analyze the presence and movement of water vapor moisture in the upper and middle levels of the atmosphere. The wavelength spectrum used to detect water vapor is in the 6.7 to 7.3 micrometer wavelength range. The darker regions in water vapor imagery are areas where very little water vapor exists in the middle and upper troposphere, and the lighter regions are very moist. Water vapor imagery is a very valuable tool for weather analysis and prediction because water vapor imagery shows moisture in the atmosphere, not just cloud patterns. This allows meteorologists to observe large-scale circulation patterns even when clouds are not present.
The National Oceanic and Atmospheric Administration (NOAA) maintains two primary constellations of environmental satellites: geostationary and polar-orbiting. These satellites are part of NOAA's integrated observing system, which includes satellites, radar, surface automated weather stations, weather balloons, sounders, buoys, instrumented aircraft and other sensors, along with the data management infrastructure needed for this system.
Geostationary satellites orbit 35,800 km (22,300 miles) above Earth's equator at speeds equal to Earth's rotation, which means they maintain their positions and provide continuous coverage. Information from geostationary satellites is used for short-term (1 day) weather forecasting and severe storm warning and tracking.
Polar-orbiting satellites make regular orbits around the Earth’s poles from about 833 km (517 miles) above the Earth’s surface. The Earth constantly rotates counterclockwise underneath the path of the satellite, making for a different view with each orbit. Information from polar-orbiting satellites is used for mid-range (3-7 day) forecasts and advanced warnings of severe weather.
GOES satellites continually view the continental United States, Pacific and Atlantic Oceans, Central and South America, and Southern Canada. To fully cover Alaska, Hawaii, the entire continental United States and the Pacific and Atlantic Oceans (for tropical storms), NOAA operates two GOES satellites simultaneously: GOES East and GOES West. GOES East is located at 75.2° W and provides most of the U.S. weather information. GOES West is located at 137.2°W over the Pacific Ocean. In addition to two operational satellites, NOAA also maintains an on-orbit spare.
Since 1975, GOES have provided continuous imagery and data on atmospheric conditions and solar activity (space weather). They have even aided in search and rescue of people in distress. GOES data products have led to more accurate and timely weather forecasts and better understanding of long-term climate conditions. NASA builds and launches the satellites and NOAA operates them.
GOES-R launched on November 19, 2016, and was followed by GOES-S on March 1, 2018. GOES-T launched on March 1, 2022, and GOES-U is planned for launch on June 25, 2024.
GOES-U, the final satellite in the GOES-R Series, launched on June 25, 2024. GOES-U launch aboard a Falcon Heavy rocket from Launch Complex 39A, at NASA’s Kennedy Space Center in Florida. GOES-U reached geostationary orbit on July 7, 2024, and was renamed GOES-19. After completing on-orbit checkout of its instruments, systems, and data products, NOAA plans to put GOES-19 into operations as GOES East, replacing GOES-16, in April 2025.
GOES-T, the third satellite in the GOES-R Series, launched on March 1, 2022. GOES-T lifted off from Space Launch Complex 41 at Cape Canaveral Space Force Station, Florida, aboard an Atlas V 541 rocket. GOES-T reached geostationary orbit on March 14, 2022, and was renamed GOES-18. GOES-18 replaced GOES-17 as the operational GOES West satellite at 137.0 degrees west longitude on January 4, 2023.
GOES-S launched on March 1, 2018 and was renamed GOES-17 when it reached geostationary orbit on March 12, 2018. GOES-17 joined its sister satellite, GOES-16, in orbit.
The first satellite in the series, GOES-R, launched on November 19, 2016, and became GOES-16 when it reached geostationary orbit. GOES-16 replaced GOES-13 as NOAA’s operational GOES East satellite at 75.2 degrees west longitude on December 18, 2017. GOES-17 served as GOES West from February 12, 2019 until it was replaced by GOES-18 on January 4, 2023. GOES-17 is now the on-orbit standby for the operational constellation.
GOES satellites are placed into a geosynchronous orbit that keeps them over a specific location on the earth. By maintaining a position hovering over a fixed point on Earth's surface, GOES are able to constantly monitor atmospheric conditions in a particular portion of the Earth's atmosphere. Note that non-geosynchronous orbits (for example polar orbits) move over an ever-rotating earth underneath them, therefore seeing a constantly changing view, which has advantages for other types of missions.
GOES-16 became operational as NOAA’s GOES East on December 18, 2017, replacing GOES-13. From its operational location of 75.2 degrees west longitude, GOES-16 is keeping watch over most of North America, including the continental United States and Mexico, as well as Central and South America, the Caribbean, and the Atlantic Ocean to the west coast of Africa.

In 2025, NOAA is celebrating 50 years of its heralded Geostationary Operational Environmental Satellite program, known as GOES. For five decades, NOAA and NASA have partnered to advance NOAA satellite observations from geostationary orbit. GOES are our sentinels in the sky: keeping constant watch for severe weather and environmental hazards on Earth and dangerous space weather. As NOAA celebrates the long legacy of the GOES, we continue to rely on these satellites for short-term forecasts of hazardous weather, detection and monitoring of environmental phenomena like wildfires, smoke, volcanic ash, dust storms and fog, and warnings of approaching space weather that can disrupt communication and navigation systems, disrupt power grids, damage satellites in space and expose astronauts to harmful radiation.
NOAA’s newest satellite, GOES-19, provided a beautiful view of Earth during the winter solstice. Currently positioned over the Western Hemisphere at 89.5° west longitude, between NOAA’s GOES East and GOES West satellites, GOES-19 captured this celestial moment from space while undergoing post-launch testing. Launched on June 25, it is set to replace GOES-16 in the GOES East position this spring. The winter solstice marks a special moment as the shortest day and longest night of the year in the Northern Hemisphere. At precisely 4:21 a.m. EST, the Northern Hemisphere reached its maximum tilt away from the sun, positioning the sun directly over the Tropic of Capricorn, 23.5° south of the equator.
As the 2024 Atlantic hurricane season comes to a close on Nov. 30, NOAA looks back at its above-average activity, with a record-breaking ramp up following a peak-season lull. The Atlantic basin saw 18 named storms with 11 intensifying into hurricanes. Five of those were major hurricanes intensifying into Category 3 or higher. GOES-16 (GOES East) is constantly monitoring the Atlantic basin for the development of tropical storm systems. Once a storm forms, GOES-16 tracks its development, movement and intensity and measures lighting activity in near real-time.
NOAA’s newest satellite, GOES-19, has been monitoring an increasingly active sun, as we enter solar maximum of Solar Cycle 25. The GOES-19 Solar Ultraviolet Imager (SUVI) and a brand-new Compact Coronagraph (CCOR-1) are now observing the sun and its influence on Earth. Recently, the GOES-19 SUVI operated in a special mode, called “extended coronal imaging (ECI).” Typically, SUVI capture’s the sun’s activity in six types of extreme ultraviolet light, each showing different temperatures on the sun. During ECI, SUVI captured images slightly off-center from the sun, using two of these light types (171 Å and 195 Å). By doing this, scientists can create three-panel mosaic images that reveal more of the sun’s outer atmosphere, known as the middle corona. This extended view helps connect the details in SUVI images with the new CCOR-1 images. As GOES-19 undergoes post-launch testing before becoming NOAA’s operational GOES East satellite in spring 2025, its data should be considered preliminary and non-operational. Once operational, the Space Weather Prediction Center (SWPC) will use data from both CCOR-1 and SUVI to issue early warnings and improve the accuracy of forecasts, protecting vital infrastructure from space weather threats.
On Oct. 29, 2024, NOAA shared the first imagery from the GOES-19 Solar Ultraviolet Imager (SUVI). The GOES-19 SUVI, which launched on June 25, 2024, began observing the sun on Sept. 24, 2024. On Oct. 3, 2024, the GOES-19 SUVI captured an X9 solar flare, the most powerful flare so far in the current solar cycle. The sun’s 11-year activity cycle has entered the solar maximum period, meaning phenomena such as solar flares and coronal mass ejections are occurring more frequently than during other parts of the solar cycle. SUVI monitors the sun in the extreme ultraviolet portion of the electromagnetic spectrum to watch for hazardous space weather that could affect Earth.
On Oct. 17, 2024, NOAA shared initial imagery from the GOES-19 lightning Mapper. The GOES-19 Geostationary Lightning Mapper (GLM) instrument, launched on June 25, 2024, is now continuously observing lightning over the Western Hemisphere. Recently, the GOES-19 GLM detected and monitored lightning activity in two extremely hazardous hurricanes – Helene and Milton. Lightning activity in the outer rainbands and eyewalls of these hurricanes was associated with rapid intensification. Frequent lightning outside the Hurricane Milton’s core was associated with intense rain bands that produced widespread flash flooding and tornadoes across Florida on Oct. 9, 2024. GOES-19 is currently undergoing post-launch testing, which includes validation and calibration of its instruments, systems and data to prepare it for operations. NOAA plans for GOES-19 to replace GOES-16 as GOES East in April 2025
The GOES-R/GeoXO quarterly newsletter for April – September 2024 is now available. We successfully launched the final satellite in the GOES-R Series! Congratulations to the team for achieving this milestone! After reaching geostationary orbit on July 7, GOES-U was renamed GOES-19. Post-launch testing is underway, and I look forward to GOES-19 becoming GOES East next April. GOES-19 hosts a new space weather instrument, CCOR-1, on behalf of NOAA’s Space Weather Follow-On Program, which will observe the solar corona and provide critical data for space weather forecasting. There has also been a lot of progress on GeoXO. We selected vendors to build the spacecraft and the ACX, OCX and LMX instruments and are on track to complete the Mission Definition Review in late 2024.
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) onboard NOAA’s GOES-19 satellite are powered on, performing well and observing the sun. On Sept. 14 2024, EXIS observed an X-class “extreme” solar flare that erupted from an active region of the sun that had just rotated into Earth’s view. Solar flares are huge eruptions of energy on the sun and often produce clouds of plasma traveling more than a million miles per hour. When these plasma clouds reach Earth, they can cause radio communications blackouts, disruptions to electric power grids, errors in GPS navigation, and hazards to satellites and astronauts. This particular flare resulted in aurorae visible as far south as Texas. EXIS, with its multiple sensors, can observe and quantify the light from solar flares and help determine in real-time whether a flare will affect us on Earth. EXIS data will provide NOAA’s Space Weather Prediction Center with early indications of impending space weather storms so forecasters can issue alerts, watches and warnings.
On Sept. 18, 2024, NOAA shared the first images of the Western Hemisphere from its GOES-19 satellite. The satellite’s Advanced Baseline Imager (ABI) instrument recently observed a number of weather events, environmental phenomena, and striking views of Earth. Wildfires in the Midwest and the Amazon blanketed nearby areas with smoke. Storms flared up over the Southeast and a low-pressure system over Canada brought severe weather. Tropical Storm Francine formed in the Gulf of Mexico and quickly developed into a hurricane, making landfall in Louisiana. GOES-19 also captured mesmerizing von Kármán vortices around Guadalupe island, cloud streets over Virginia, and cumulus clouds over the Midwest. GOES-19 is currently undergoing post-launch testing, which includes validation and calibration of its instruments, systems and data to prepare it for operations. NOAA plans for GOES-19 to replace GOES-16 as GOES-East in April 2025.
On Sept. 11, 2024, NOAA satellites monitored Hurricane Francine as it made landfall in Louisiana as a Category 2 hurricane. Francine developed into a tropical storm in the Gulf of Mexico on Sept. 9, as the historical peak of Atlantic hurricane season approached. The storm brought flash flooding and caused widespread power outages in Louisiana, Mississippi and Alabama. GOES-16 (GOES-East) watched in near real-time as Francine developed into a tropical storm and intensified into a hurricane. The satellite provided a detailed look of the storm and monitored cloud top cooling and lightning activity within the hurricane.
The Space Environment In-Situ Suite (SEISS) instrument onboard NOAA's GOES-19 satellite on June 25, 2024, is now sending radiation data back to Earth. Data collected from SEISS over the three-day time period from August 23–25, 2024, show a number of radiation belt disturbances. The radiation belts are regions of space around Earth filled with energetic electrons and protons that can damage or interfere with satellite electronics. The GOES-19 SEISS Magnetospheric Particle Sensor - High Energy observed several large dropouts followed by rapid increases in the radiation belt electron and proton fluxes during these disturbances. Following the rapid increases, MPS-HI observed periodic "drift echoes" (short duration flux enhancements), most clearly in the three lowest-energy proton channels (96 keV, 138 keV, and 193 keV traces), as these enhanced fluxes repeatedly drifted around the Earth and passed by the GOES-19 satellite. Once GOES-19 assumes its operational role as NOAA’s GOES-East satellite, the Space Weather Prediction Center will use GOES-19’s SEISS data to issue solar radiation storm and radiation belt alerts.
On Aug. 14, 2024, NOAA satellites watched Tropical Storm Ernesto intensify into a hurricane. The storm brought strong winds and flooding to the Virgin Islands and Puerto Rico before moving northward. As it traveled northward over the Atlantic Ocean toward Bermuda, Ernesto intensified into a Category 2 hurricane. On Aug. 17, Hurricane Ernesto made landfall in Bermuda as a Category 1 hurricane. Hurricane Ernesto also caused dangerous swells and rip currents along the U.S. East Coast. GOES-16 monitored the storm as it developed and intensified in near real-time, helping forecasters determine what areas would be impacted. Infrared imagery from GOES-16 indicated what areas of the hurricane were the most intense. The GOES-16 Geostationary Lightning Mapper also captured lightning activity within the storm.
In early August 2024, NOAA satellites tracked Debby, a storm that impacted Florida’s Big Bend region near Steinhatchee before moving up the East Coast, causing widespread flooding and damaging winds as far north as New York state with numerous destructive tornadoes along its path. NOAA’s GOES-16 satellite monitored and tracked the storm in near real-time as it developed and moved northward. GOES-16 imagery revealed details such as cloud top cooling, winds and lightning activity, which help estimate a storm’s intensity.
The Goddard Magnetometer (GMAG) instrument, launched onboard NOAA’s GOES-19 satellite on June 25, 2024, is now transmitting magnetic field measurements down to Earth. On July 23, 2024, the GOES-19 GMAG captured a space weather phenomenon known as electromagnetic ion cyclotron waves. These waves play a significant role in controlling the levels of dangerous energetic particles that can cause damage to satellites and harm astronauts. GMAG space weather products can help to improve forecasts of the likelihood of elevated levels of dangerous energetic particles.
Roughly 100 wildfires are raging out of control across the western United States and hundreds more are burning in Canada, destroying homes, forcing evacuations, and affecting air quality. NOAA satellites have been closely monitoring these blazes, including California’s Park Fire, which is currently the largest active wildfire in the U.S. The Park Fire, which started on July 24, 2024, is believed to have been ignited by arson. A suspect has been arrested, accused of pushing a burning car into a gully, sparking the blaze. As of Aug. 1, the fire has consumed 392,480 acres across Butte, Plumas, Shasta, and Tehama counties. Fueled by very dry grass and brush, and driven by strong winds, the fire is only 18% contained.
At the end of a humid day in the Midwest, GOES East watched as a derecho ripped through the region on July 15. The storm system developed and moved east across Iowa before reaching Illinois, Indiana and southwest Michigan. The Chicago National Weather Service office confirmed the derecho spawned at least 19 tornadoes in the Chicagoland area. GOES East saw the storms grow in size and intensity over Iowa. The Advanced Baseline Imager onboard GOES East captured infrared imagery revealing the structure of the storm and where it was the most intense. The Geostationary Lightning Mapper on GOES East also measured lightning within the storm system.
Hurricane Beryl, the first hurricane of the 2024 Atlantic hurricane season, rapidly strengthened to a Category 5 storm unusually early in the year. This explosive strengthening was fueled in part by exceptionally warm ocean temperatures. Beryl first formed as a tropical depression on June 28, 2024, with winds of 35 mph; within the first 24 hours, the storm rapidly intensified into a hurricane with winds of 75 mph. This was the farthest east that a hurricane has formed in the month of June. In the following 24 hours, Beryl underwent another instance of rapid intensification becoming an extremely dangerous Category 4 hurricane. At that point Beryl became the first Category 4 hurricane to form in the month of June. On July 2, 2024, Beryl became the earliest Category 5 hurricane observed in the Atlantic on record and only the second Category 5 hurricane to occur in July.
On July 7, 2024, GOES-U executed its final engine burn, placing the satellite in geostationary orbit 22,236 miles above Earth. Upon reaching this milestone, GOES-U was renamed GOES-19. GOES satellites are designated with a letter prior to launch and a number once they achieve geostationary orbit. NOAA’s GOES-U satellite launched on June 25, 2024, lifting off from NASA’s Kennedy Space Center in Florida. The satellite launched aboard a SpaceX Falcon Heavy rocket from Space Launch Complex 39A. The launch was managed by NASA’s Launch Services Program, based at Kennedy Space Center.
GOES-U, the latest of NOAA’s four advanced geostationary satellites, soared into orbit on a SpaceX Falcon Heavy rocket at 5:26 p.m. EDT from NASA’s Kennedy Space Center in Florida. At 10:18 p.m., mission managers confirmed the spacecraft’s solar arrays successfully deployed, and the spacecraft was operating on its own power. GOES-U will take about two weeks to reach its geostationary orbit. Once there, the satellite will be renamed GOES-19. On board GOES-U is a suite of seven instruments for collecting advanced imagery and atmospheric measurements, providing real-time mapping of lightning activity, and detecting approaching space weather hazards. Also on board for the first time is the compact coronagraph that will observe the sun’s outermost layer, called the corona, for large explosions of plasma that could produce geomagnetic solar storms.
NASA, NOAA, SpaceX, and GOES-U mission managers met on June 20 to conduct a Flight Readiness Review at NASA’S Kennedy Space Center in Florida. During the review, teams provided an update on the mission status and certified the readiness to proceed with final launch preparation activities.
For nearly 50 years, NOAA and NASA have partnered to develop NOAA’s geostationary satellites as part of the most sophisticated weather-observing, environmental monitoring, and space weather monitoring satellite system in the world. When NOAA’s GOES-U satellite is launched, it will be the fourth and final satellite in the GOES-R Series, and a bridge to a new age of advanced satellite technology – GeoXO. A new video, “From GOES to GeoXO: Past Highlights to Future Horizons,” offers a retrospective of the GOES legacy and a look to the future with GeoXO.
On June 15, 2024, GOES-U, encapsulated in its protective payload fairing, arrived at NASA Kennedy and SpaceX’s hangar at the spaceport’s Launch Complex 39A. Crews began transporting the satellite from the Astrotech Space Operations Facility in Titusville, Florida, on June 14, with the operation finishing early on June 15. The next mission milestone includes connecting the encapsulated GOES-U to the SpaceX Falcon Heavy rocket that will launch it into space, ahead of rolling the stack out to the launch pad.
On June 13, 2024, technicians encapsulated the 20-foot-tall GOES-U satellite inside two payload fairing halves in preparation for connecting it to the Falcon Heavy rocket that will launch the satellite into space. During the ascent phase of the launch, the fairing halves will protect GOES-U from aerodynamic pressure and heating. Once GOES-U no longer requires this protection, approximately four minutes after liftoff, the halves will be jettisoned and return to Earth, where SpaceX crews will recover them for use on future missions.
On June 6, 2024, NASA and NOAA hosted a media availability to view and photograph the GOES-U satellite at the Astrotech Space Operations payload processing facility in Titusville, Florida. Subject matter experts from NASA, NOAA, Lockheed Martin, and L3Harris Technologies provided a mission overview and answered questions about the satellite’s capabilities to assist meteorologists with predicting, observing, and tracking hazardous weather events on Earth and in space. The opportunity provided media with a last look at the final weather-observing and environmental monitoring satellite in NOAA’s GOES-R Series before technicians prepare it for launch aboard a SpaceX Falcon Heavy rocket. View photos and video of media day.
Last month, we challenged kids to draw how they imagine lightning looks either within the clouds or striking the ground, from above the sky or from their window. The GOES-U satellite will help scientists “see” lightning and predict where it will strike, helping meteorologists forecast the path of hurricanes, how strong severe thunderstorms can become, and when tornadoes will form. Thank you to everyone who participated! We chose 23 selections to feature.
Earth-observing satellites can see many different things, from changing seasons, weather patterns, and land features. From their unique view, satellites can also observe the deep swirling hues and colors of the ocean. With data from NASA’s PACE mission now available, NOAA and NASA are collaborating to develop applications for monitoring various indicators of ecosystem health. NOAA is also preparing for a more advanced Ocean Color instrument (OCX) to be flown on the future GeoXO mission. Having an ocean color instrument on a geostationary satellite such as GeoXO will allow continuous monitoring of a specific area. Additionally, its higher resolution imagery will improve observations of water clarity, chlorophyll concentrations, and help distinguish different types of phytoplankton. GeoXO will begin operating in the early 2030s, taking over after the GOES-R series reaches the end of its operational lifetime.
Have you ever watched a lightning storm from your window at home? Did you know that scientists can use weather satellites to watch lightning from above, too? On June 25, 2024, NOAA will be launching its latest weather satellite called GOES-U (GOES is short for Geostationary Operational Environmental Satellite). GOES-U will be the fourth and final satellite in the GOES-R group of satellites that keep an eye on Earth’s weather from space. GOES-U will also help scientists “see” lightning and predict where it will strike.
Challenge: Draw how you imagine lightning to look, either within the clouds or striking the ground, from above the sky or from your window. Use any materials you would like – crayons, markers, pencils, pens, aluminum foil, paint, yarn, or anything else you find. The sky's the limit!
The art challenge is open through May 31, 2024. Selected art submissions will appear online and in social media the first week of June. Visit our art challenge webpage for instructions for submitting your art.
Throughout history, humans have wondered what Earth looked like from above. The advent of satellites changed our perspective dramatically, though early imagery was often blurry and lacked detail. Today, thanks to decades of technological advancements and innovation, the quality and resolution of satellite imagery has significantly improved. Satellites from NOAA and other organizations around the world capture vital information that help us stay safe, while also sharing the beauty of our planet from afar. For us, every day is Earth Day!
On April 8, 2024, the moon moved directly between the Earth and sun, completely blocking the sun’s light and causing a total solar eclipse. During this event, the moon’s shadow passed over parts of Mexico, the United States, and Canada, and millions of people were treated to a celestial show where the sky darkened as if it were dawn or dusk throughout its path of totality. NOAA satellites play a crucial role in observing solar eclipses and their effects. GOES-16 and GOES-18 watched the moon’s shadow pass over the Earth. The satellites also captured the effects of the eclipse shadow on surface weather, including the drop in land and air surface temperature, and dissipation of clouds. Although solar eclipses happen all over the Earth about twice a year, the next total solar eclipse is not predicted to occur in the United States until March 30, 2033, where it will be seen from northwestern Alaska. Another will occur across parts of Canada, Montana, and the Dakotas on Aug. 23, 2044. However, it won’t be until Aug. 12, 2045, when one will cross the contiguous United States from California to Florida.
The GOES-R/GeoXO quarterly newsletter for January – March 2024 is now available. Excitement is building for the GOES-U launch, now scheduled for June 25, 2024. SpaceX has repaired the liquid oxygen leak found during testing of the center core booster and launch preparations are back on track. The team is preparing for satellite fueling and encapsulation in the rocket fairing, conducting mission tests and rehearsals, and preparing for the remaining pre-launch reviews. Meanwhile, we are also working hard on GeoXO. The team conducted a successful kickoff meeting for the Sounder and work continues on the Imager. Evaluation boards are busy reviewing proposals for the spacecraft and the OCX, LMX, and ACX instruments. We plan to award the remaining GeoXO contracts by fall.
On March 23–24, 2024, NOAA’s GOES-16 and GOES-18 satellites, and others operated by international partners, observed numerous flares erupt from the sun, including a powerful X-class solar flare. Additionally, a surge of extremely hot plasma, known as a coronal mass ejection (CME), raced toward Earth, resulting in geomagnetic storms and auroras. The EXIS instruments onboard both GOES-16 and GOES-18 detected the flare. The satellites’ SUVI instruments viewed the flare and the initiation of the CME. Solar activity is expected to increase as Solar Cycle 25 reaches its peak, which is expected this year. NOAA and partner satellites will continue to watch for increased solar activity.
NOAA is preparing for a milestone satellite launch in 2024. GOES-U will be the fourth and final satellite in NOAA’s latest generation of geostationary operational environmental satellites called the GOES-R Series—the nation’s most advanced weather-observing and environmental monitoring satellite system. Like the three other GOES-R Series satellites already in orbit, GOES-U will provide near real-time, high-resolution imagery that will deliver critical information for weather forecasts, severe weather prediction, lightning detection, and space weather forecasts. GOES U will also carry something new when it launches – a critical space weather instrument called the Compact Coronagraph-1, or CCOR-1. Being able to monitor the sun’s corona helps scientists detect and characterize coronal mass ejections that can spark geomagnetic storms here on Earth– the costliest type of space weather events that can cause widespread damage to power grids, satellites, and communication and navigation systems.
NASA and SpaceX now are targeting Tuesday, June 25, for the launch of GOES-U, the fourth and final satellite in National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellites (GOES) – R Series. The new launch date allowed time for teams to fully repair and test the Falcon Heavy core booster after a liquid oxygen leak was identified during routine new booster testing in February. NASA and SpaceX teams have resumed preparation of the GOES-U launch. GOES-U will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.
Since late February, NOAA satellites have been tracking wildfires that spread through the Texas Panhandle. The largest wildfire in the state’s history broke out on Feb. 26 and quickly spread, fueled by dry, windy conditions. By Mar. 4, the blaze, known as the Smokehouse Creek fire, had become one of the largest fires in U.S. history. GOES-16 (GOES East) observed these fires in near-real time. This geostationary satellite keeps constant watch over the same geographic area over time, and helps to locate fires, detect changes in a fire’s behavior, and predict its direction. By combining data from multiple channels on its Advanced Baseline Imager (ABI) instrument, both a fire’s hot spot and associated smoke plume can be visualized.
In honor of Women’s History Month, a new web feature turns the spotlight on women in NOAA’s Office of Geostationary Earth Orbit Observations. Celebrating Women in GEO tells the stories of women who are driving innovation and who have been instrumental within its geostationary satellite programs. These remarkable individuals exemplify the spirit of innovation, dedication, and leadership, and are helping to shape the future of how we monitor our constantly changing world. Ultimately, the work these women do helps safeguard lives, protect communities, and preserve our planet’s vital natural resources. Their contributions are also inspiring future generations to pursue careers in science, technology, engineering, and mathematics (STEM).
As we leave meteorological winter behind, NOAA satellites have been monitoring the extent of ice coverage in the Great Lakes. The Great Lakes typically see peak ice coverage in late February to early March. Ice plays an important role in the ecosystems, economy, and coastal resilience of the Great Lakes. In 2024, ice coverage reached a historic low. A number of factors have contributed to the historic low this year, such as a strong El Niño and well above-average temperatures this winter. NOAA satellites have observed little ice on the Great Lakes this year.
NASA and SpaceX are now targeting no earlier than May 2024 for the launch of NOAA's GOES-U satellite. The new date allows for additional testing and preparation of a new Falcon Heavy center core booster after a liquid oxygen leak was discovered during routine new booster testing. GOES-U is the fourth and final satellite in the GOES-R Series of advanced geostationary satellites.
The latest video in the Earth from Orbit series highlights GOES-U’s arrival at Kennedy Space Center last month. After being packed in a high-tech shipping container that acts as a mobile clean room, GOES-U caught a ride aboard a C-5 Super Galaxy aircraft from Buckley Space Force Base in Colorado to NASA’s Kennedy Space Center in Florida. After landing, the satellite was taken to Astrotech Space Operations, where it was removed from its shipping container, inspected, and placed onto a test stand. GOES-U will now undergo final preparations for a spring 2024 launch from Kennedy Space Center, where it will launch aboard a SpaceX Falcon Heavy rocket.
NOAA’s GOES-U, the fourth and final satellite in the GOES-R Series of advanced weather-observing and environmental monitoring satellites, arrived at NASA’s Kennedy Space Center in Florida on Jan. 23, 2024, to begin final preparations for its upcoming launch. Shipping a satellite is no small feat. GOES-U is the size of a small school bus and weighs over 6,000 pounds! The spacecraft team at Lockheed Martin in Littleton, Colorado, where GOES-U was built, packed the satellite in a high-tech shipping container that protected its sensitive instruments and acted as a mobile clean room during transport. GOES-U was then driven to Buckley Space Force Base in Aurora, Colorado, and loaded on the C-5M Super Galaxy cargo transport that carried it to Florida. GOES-U safely landed at the NASA Launch and Landing Facility airstrip at Kennedy Space Center and was transported to the Astrotech Space Operations spacecraft processing facility in nearby Titusville, where it will go through a series of electrical tests to confirm it is working properly and mechanical configurations to prepare it for launch. GOES-U is scheduled to launch no earlier than April 30, 2024.
NOAA’s GOES-U, the fourth and final satellite in the Geostationary Operational Environmental Satellites (GOES) – R Series, the Western Hemisphere’s most advanced weather-observing and environmental monitoring system, is entering the final stage of preparations before liftoff. NASA and SpaceX are targeting no earlier than April 30 for the launch of GOES-U on a Falcon Heavy rocket. The GOES-U team has spent years building the instruments and spacecraft, integrating all the satellite’s components, and conducting rigorous testing to ensure it can withstand the harsh launch conditions and successfully take up residence 22,236 miles above Earth. Before that happens, the spacecraft must complete several final milestones. Learn more about GOES-U’s road to launch.
The GOES-R/GeoXO quarterly newsletter for October – December 2023 is now available. Happy New Year! It’s a very exciting time for the GEO Program! We are gearing up to launch the last of the GOES-R Series satellites. GOES-U will soon ship to Kennedy Space Center and begin final preparations for its planned launch in April. GeoXO also had a successful quarter. The final development RFP, for the ACX instrument, was released in October. Evaluation boards are busy reviewing proposals for the spacecraft and the OCX, LMX, and ACX instruments. GOES-16 and GOES-18 continue to provide critical data to keep us informed of and safe from severe weather and environmental hazards. The program is looking forward to more GEO successes in 2024!
NOAA satellites see our planet from a unique and captivating perspective. Every year, they capture the beauty and wrath of Mother Nature unfolding beneath them—devastating hurricanes, raging wildfires, erupting volcanoes—as well as the changing seasons, ocean color, nighttime lights, and more. The view of NOAA satellites isn’t just limited to Earth; they also capture images of our moon and the sun as we navigate our cosmic journey. As we head into the new year, take a look back at some satellite imagery highlights from 2023.
