KENNEDY SPACE CENTER, Fla. — The launch window extended for an hour, and United Launch Alliance (ULA) needed every minute of it. After resolving multiple issues, the Atlas V rocketed into the black on a mission to send the most advanced weather satellite, GOES-R, into geostationary orbit.
The first issue that cropped up turned out to be a false-positive indicator on the launch vehicle. ULA’s frustrations didn’t end there, however. The Eastern Range also encountered an issue, which delayed the liftoff time to the very end of the window. Finally, under nearly perfect conditions, the Atlas V 541 with GOES-R lifted off at 6:42 p.m. EST (23:42 GMT) from Space Launch Complex-41 at Cape Canaveral Air Force Station.
The workhorse of ULA‘s stable of launch vehicles, the Atlas V for this mission was set up in its 541 configuration: this includes a 5-meter payload fairing, four supplemental solid rocket boosters, and a single-engined Centaur stage.
It was the fourth launch of this configuration of the Atlas V, with the most notable payload being the Mars Science Laboratory – otherwise known as Curiosity – which took to the skies in November 2011.
