A collaborative NOAA & NASA program

April 18, 2018: 1st Quarter 2018 GOES-R Series Program Quarterly Newsletter

The GOES-R Series Program quarterly newsletter for the time period January – March 2018 is now available. GOES-S lifted off on a picture perfect day right at the opening of the launch window on March 1. The satellite reached geostationary orbit on March 12 and was renamed GOES-17. GOES-17 is now undergoing post-launch testing in preparation for taking over as NOAA’s GOES West operational satellite late this year. View the 1Q 2018 newsletter.

April 9, 2018: What’s Next for GOES-17

On March 1, 2018, at 5:02 PM ET, NOAA’s GOES-S satellite blasted off into space and soon took its place as GOES-17, the nation’s newest satellite in NOAA’s most advanced geostationary series. The Atlas V rocket that launched the satellite propelled it into orbit 22,000 miles above Earth. Although the young satellite has already traveled far from home, its journey to become a vital component of the United States’ weather forecasting operations is only just beginning. Find out what's next for our newest member of the team in this feature.

April 4, 2018: First GOES-17 Magnetometer Data

On March 22, 2018, the GOES-17 Magnetometer (MAG) became the first instrument on the satellite to begin transmitting data! This figure shows data from the outboard Magnetometer instrument on board the GOES-17 satellite. The data has been filtered to highlight a space weather phenomenon known as plasma waves. These waves play a significant role in controlling the levels of dangerous energetic particles that can cause damage to satellites and harm astronauts. An important characteristic of these waves is how fast they oscillate up and down or their frequency (shown in the bottom panel of the figure). The Magnetometers on the GOES-R Series of satellites, with five times higher resolution, can observe more wave frequencies allowing us to undertake research into new space weather products that help forecasters better determine the likelihood that elevated levels of dangerous energetic particles will occur during space weather events.

March 12, 2018: GOES-S Reaches Geostationary Orbit

On March 12, GOES-S executed its final liquid apogee engine burn, placing the satellite in geostationary orbit 22,236 miles away. GOES-S is now GOES-17! Tomorrow, GOES-17 will perform its second stage solar array deployment, releasing the solar array yoke and solar pointing platform. In the days that follow, several maneuvers will be conducted to put GOES-17 in its 89.5 degrees west longitude checkout position. Learn what’s next for GOES-17 in this feature story.

March 7, 2018: A New View of the Sun

When the sun flared dramatically last September, causing geomagnetic storms and radio blackouts on Earth, a new NOAA solar telescope captured the drama from a different perspective. Now, NOAA has released these new images to the scientific community. The primary mission for the GOES-R Series Solar Ultraviolet Imager, or SUVI, is to support space weather forecasting operations at NOAA’s Space Weather Prediction Center, but its unique properties offer several opportunities for new research. Learn more in this feature from NOAA’s National Centers for Environmental Information.

March 1, 2018: GOES-S Solar Array Deploys

After a successful separation from the Centaur upper stage, GOES-S began flying freely. Shortly after, the satellite completed deployment of the Stage 1 solar array that will generate electricity for the spacecraft during its mission. GOES-S is orbiting above the Earth, its systems are in good health and it is operating on its own. Learn more in the NOAA press release.

March 1, 2018: Liftoff! Atlas V Clears the Launch Pad With NOAA’s GOES-S Satellite

Booster ignition and liftoff of the United Launch Alliance Atlas V rocket at 5:02 p.m. EST, from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, carrying NOAA’s GOES-S satellite. The rocket is on its way, carrying NOAA’s second in a series of four next-generation weather satellites. About four minutes into flight, a series of key events occurs in rapid succession: Atlas booster engine cutoff, separation of the booster from the Centaur upper stage, ignition of the Centaur main engine for its first of two burns, then jettison of the payload fairing. Follow the GOES-S Blog for updates.

February 28, 2018: GOES-S Roll to Pad

The United Launch Alliance Atlas V rocket and its GOES-S payload were moved to the launch pad today as preparations continue for Thursday’s launch from Space Launch Complex 41. The Atlas V is in its 541 configuration, which means it has the 5-meter-diameter payload fairing, four solid-fueled boosters and the Centaur upper stage is equipped with a single engine. Liftoff remains on schedule for 5:02 p.m. EST tomorrow. Meteorologists with the U.S. Air Force 45th Space Wing are predicting an 80 percent chance of favorable weather for liftoff of the Atlas V rocket. On launch day, the primary weather concern is cumulus clouds and strengthening ground winds.

February 28, 2018: How to Launch a Rocket

NOAA GOES-S will travel to space aboard a ULA Atlas V 541 expendable launch vehicle, or rocket. The “541” refers to the configuration of the rocket: payload fairing, or nose cone, that covers the satellite is approximately 5 meters in diameter; the four solid rocket boosters that generate extra thrust off the launch pad; and a single engine on the Centaur upper stage. Fully fueled, GOES-S’s Atlas V 541 rocket weighs more than 1 million pounds and is approximately 197 feet tall.

GOES-S and its Atlas V rocket will begin its journey to space when the booster engine and solid rocket boosters ignite and the rocket blasts off. Just under 2 minutes after leaving the launch pad, the rocket’s four solid rocket boosters will complete their burns and be jettisoned while the Atlas booster continues to burn. Approximately 90 seconds later, the payload fairing halves separate and fall back, no longer needed after leaving Earth’s atmosphere. About a minute later, the booster engine will shut down, known as booster engine cutoff (BECO), and the booster and Centaur upper stage separate. With the upper stage now flying free, the main engine will start its first burn. This burn will last for nearly eight minutes before the first main engine cutoff (MECO-1).

After a total of three burns of the Centaur upper stage engine, GOES-S will separate from the upper stage and fly alone in space for the first time! This will occur roughly three and a half hours after liftoff. In the days that follow, GOES-S will perform several instrument deployments and a series of maneuvers to bring the satellite into geostationary orbit. This is scheduled to occur 17 days after launch. Once NOAA GOES-S, now GOES-17, is placed in geostationary orbit, it will undergo a period of checkout and validation, moving to the GOES West operational position in late 2018.

February 21, 2018: GOES-S and the Western Frontier

Working in concert with the recently launched GOES-16, the two new geostationary weather satellites will provide constant watch over the United States and the Western Hemisphere, helping monitor severe storms, wildfires, and daily weather patterns. GOES-S will provide better data coverage over the northeastern Pacific, where many weather systems that affect the western U.S. originate. Greater coverage means that GOES-S will be in an ideal location to monitor weather hazards unique to the western U.S. These include wildfires, coastal fog, and atmospheric river events, when storms from the Pacific dump heavy rain and snow over the western U.S. Better monitoring of these heavy precipitation events will lead to timelier warnings to the public about hazards such as flooding and mudslides.
