Atlas V GOES-T Mission Profile

A United Launch Alliance (ULA) Atlas V 541 rocket passed the Launch Readiness Review on Feb 26th, and will launch Geostationary Operational Environmental Satellites (GOES) –T mission for NOAA, NASA and NASA’s Launch Services Program (LSP). The launch is planned for March 1st from Space Launch Complex-41 at Cape Canaveral Space Force Station, Fla.

Weather conditions have improved at Kennedy Space Center, Space Force Delta 45 is now predicting 80% chance of acceptable weather; Primary concerns are cumulus clouds and liftoff winds.
Total time from Launch to spacecraft separation will be just over 3 1/2 hours.
LAUNCH DATE: March 1, 2022

The Atlas V 541 rocket, fitted with four side-mounted solid rocket boosters, will deliver GOES-T into an optimized geosynchronous transfer orbit (GTO) three-and-a-half hours after liftoff.

Atlas V enhances the GOES-T satellite’s trip to space by using all the rocket’s performance to deliver the payload with a much higher perigee, or low point of the transfer orbit, and substantially reducing inclination relative to the equator in contrast to standard GTOs. Those actions by the launch vehicle benefit the satellite by getting GOES-T closer to its final geosynchronous orbit, thereby requiring fewer orbital maneuvers, and conserving its onboard fuel supply for longer mission life.

The satellite will operate 22,236 miles (36,000 km) above Earth to cover the western half of the continental U.S., Alaska, Hawaii, Mexico, Central America, and surrounding Pacific Ocean waters. It will replace GOES-17 (launched as GOES-S) as the GOES-West observatory, working in tandem with GOES-16 (launched as GOES-R) in the GOES-East location that covers the Eastern U.S., Caribbean, and Atlantic.

Atlas and Delta rockets have launched all the GOES weather satellites to date; GOES-T will be the 19th launched since 1975.
