Delta IV launch early Friday morning

Early Friday morning at midnight, United Launch Alliance is

launching a Delta IV from Cape Canaveral carrying the third and fourth satellites for the Geosynchronous Space Situational Awareness Program, or GSSAP. The rocket will be launching in its Medium+ (4,2) configuration with a 4m payload fairing and 2 strap-on solid rocket boosters. Currently, weather favours an 80% chance of a successful liftoff. The launch will occur sometime between 12am-4am Friday, no exact launch time has been announced. If the launch gets delayed 24 hours there's another launch opportunity Saturday morning.
