United Launch Alliance issued the following statement regarding the scrub:
(Vandenberg Air Force Base, Calif. Jan. 11, 2018) – The launch of a United Launch Alliance Delta IV carrying the NROL-47 mission was scrubbed today due to an issue with a ground system valve.
The launch is planned for Friday, Jan. 12, from Space Launch Complex-6 at Vandenberg Air Force Base. The forecast shows a 90 percent chance of favorable weather conditions for launch. The launch time is 1:00 p.m. PT.
