NOAA’s GOES-T Reaches Geostationary Orbit, Now Designated GOES-18

On March 14, 2022, GOES-T executed its final engine burn, placing the satellite in geostationary orbit 22,236 miles above Earth.

Upon reaching this milestone, GOES-T was renamed GOES-18. GOES satellites are designated with a letter prior to launch and a number once they achieve geostationary orbit. NOAA’s GOES-T satellite launched on March 1, 2022, at 4:38 p.m. EST, lifting off from Cape Canaveral Space Force Station in Florida. The satellite launched aboard a United Launch Alliance Atlas V rocket from Space Launch Complex 41. The launch was managed by NASA’s Launch Services Program, based at Kennedy Space Center.

GOES-T separated from the Atlas V Centaur upper stage at 8:11 p.m. EST on March 1. GOES-T mission managers confirmed that its solar arrays successfully deployed at 8:28 p.m. EST and the satellite was operating on its own power.

The launch vehicle delivered GOES-T to a geostationary transfer orbit, a highly elliptical orbit where the satellite is close to the Earth during one part of its orbit and far from the Earth on the opposite side. Placing GOES-T in a geostationary transfer orbit provides the satellite a path to reach its final geostationary orbit over the equator (see diagram below). After a series of orbit-raising maneuvers and engine burns, on March 14, GOES-T was delivered into a circular geostationary orbit. The satellite is now in position to orbit at the same rate Earth rotates, so it can keep constant watch over the same region.
