First Stage Liquid Oxygen Loading Beginning
Liquid oxygen is flowing into the first stage of the United Launch Alliance Atlas V rocket. The engine, seen above, will combine the oxygen with refined kerosene to generate about 860,000 pounds of thrust at liftoff. This Atlas V is equipped with four solid-fueled boosters that will provide extra thrust to lift the rocket and its GOES-R satellite into space. Launch remains on schedule for 5:42 p.m. EST.
