Cape Canaveral Air Force Station, Fla. (July 23, 2014) – The launch of a United Launch Alliance Delta IV carrying the AFSPC-4 mission was scrubbed today due to an issue with the ground support equipment environmental control system that supports the launch vehicle.

The launch is rescheduled for Thursday, July 24 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida, pending resolution of the ground environmental control system item. The launch time is 6:59 p.m. EDT at the opening of a 65-minute window. The forecast for July 24 shows a 30 percent chance of favorable weather conditions for the launch tomorrow.
