GOES-S Now in Geosynchronous Transfer Orbit above Earth

NOAA's GOES-S satellite launches on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

The second in a series of four next-generation weather satellites is now in geosynchronous transfer orbit above the Earth. NOAA’s Geostationary Operational Environmental Satellite-S (GOES-S) launched on a 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.

There were no weather constraints at the time of rocket liftoff.

“It was a chamber of commerce day,” said NASA Launch Director Tim Dunn. “We’ve been working on GOES-S for about 15 months. This is a huge year for the Launch Services Program.”

GOES-S separated from the United Launch Alliance Centaur upper stage at 8:34 p.m. EST, followed shortly afterward by mission manager confirmation that the spacecraft’s Stage 1 solar array successfully deployed and the spacecraft was operating on its own power.

When it reaches geostationary orbit 22,300 miles above Earth, in approximately two weeks, it will be renamed GOES-17. It is the second in the GOES-R Series of weather satellites that includes GOES-16 (formerly GOES-R), along with -S, -T and -U. When the satellite is declared operational, late this year, it will occupy NOAA’s GOES-West position and provide faster, more accurate data for tracking wildfires, tropical cyclones, fog and other storm systems and hazards that threaten the western United States, including Hawaii and Alaska, Mexico, Central America and the Pacific Ocean, all the way to New Zealand. More information about NOAA’s GOES satellites is available at https://www.nasa.gov/content/goes.

NOAA manages the GOES-R Series program through an integrated NOAA/NASA office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. NASA also oversees the acquisition of the spacecraftinstruments and launch vehicles. Lockheed Martin Space of Littleton, Colorado, built the spacecraft and is responsible for spacecraft development, integration and testing.

This concludes today’s coverage of the GOES-S countdown, launch and ascent into space.

Centaur Stage in Coast Phase

The Centaur stage of a United Launch Alliance Atlas V rocket is firing its small thrusters to position itself and the GOES-S payload into the proper position to fire its main engine for the final time during the mission.  NASA TV will resume coverage at 8:15 p.m. EST. Spacecraft separation is set to occur at approximately 8:31:55 p.m.

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.

T-4 Minutes and Counting

The GOES-S countdown is underway toward a liftoff at 5:02 p.m. EST. During the last four minutes of the countdown, the Atlas and Centaur propellant tanks will be brought up to flight pressure, the rocket and spacecraft will be confirmed on internal power, and the Eastern Range and launch managers will perform final status checks. A computerized autosequencer will take over the countdown in order to conduct a host of activities in precise order.

NOAA’s GOES-S Ready to Launch Aboard an Atlas V Rocket

Good afternoon from Kennedy Space Center in Florida. A United Launch Alliance Atlas V rocket stands ready for liftoff at Space Launch Complex 41 at Cape Canaveral Air Force Station. The Atlas V will carry NOAA’s Geostationary Operational Environmental Satellite-S (GOES-S). Launch is targeted for 5:02 p.m. EST, at the beginning of a two-hour launch window today.

The weather forecast for today’s launch is now at a 90 percent chance for favorable weather at liftoff.
