The GOES-R, GOES-S, and GOES-T launch vehicle is an Atlas V 541 expendable launch vehicle (ELV). The term expendable launch vehicle means each vehicle is only used once. The three numbers in the 541 designation signify a payload fairing, or nose cone, that is approximately 5 meters (16.4 feet) in diameter; four solid-rocket boosters fastened alongside the central common core booster; and a one-engine Centaur upper stage.

A launch vehicle is chosen based on how much mass the vehicle can lift into space. A two-stage Atlas V 541 launch vehicle was selected for the GOES-R, S and T launches because it has the right liftoff capability for the heavy weight requirements.

The GOES-R satellites weigh 6,173 pounds, or 2,800 kilograms at launch. The launch vehicle is 191 feet tall and will weigh 1.17 million pounds


Atlas Stage 1

Stage 1: Atlas V Rocket: Fuel and oxygen tanks that feed an engine for the ascent; powers spacecraft into Earth orbit.

Atlas rocket motors

Solid Rocket Motors: Used to increase engine thrust; four total.


Atlas Centaur

Stage 2: Centaur: Fuel and oxidizer and the vehicle's "brains"; fires twice, once to insert the vehicle-spacecraft stack into low Earth orbit.


Atlas payload fairing

Payload Fairing: Thin composite or nose cone to protect the spacecraft during the ascent through Earth's atmosphere.
