Go for Cryo Loading

The launch team completed its polls confirming they are reading to begin loading supercold propellants – known as cryogenics – into the Atlas V rocket and its Centaur upper stage. The countdown is in a planned hold at T-2 hours, but everything is on schedule for liftoff at 5:42 p.m. EST. The launch window extends for one hour today to begin the GOES-R mission.
