Marc’s Update: The ULA launch of the Delta IV carrying the GPS IIF-01 satellite has been tentatively rescheduled for May 27 according to 45th Space Wing Public Affairs. The launch window for Thursday is 11-11:19 p.m. EDT.

“The launch of a Delta 4 rocket carrying the first in a new series of next generation GPS satellites has been rescheduled for Sunday night (May 23) at 11:17 PM EDT from Cape Canaveral, Florida after the countdown was halted barely 4 minutes prior to liftoff, shortly before midnight on Friday (May 21). The last minute countdown scrub was called after loss of “the telemetry signal between the GPS and the satellite ground support equipment,” according to a statement issued by the Air Force and United Launch Alliance (ULA).”
