24-hour scrub. Nothing today.
From SpaceFlightNow.com
“Today’s planned liftoff of the United Launch Alliance Atlas 5 rocket carrying the Air Force’s next durable and secure communications satellite in the Advanced Extremely High Frequency series was postponed by a purge problem feeding to the Centaur interstage adapter. Launch from Cape Canaveral has been rescheduled for Friday at 2:42 p.m. EDT (1842 GMT).”
I’ll post the live thread tomorrow morning.
