If all goes as now planned, a United Launch Alliance Delta IV Heavy rocket will soar from Cape Canaveral Space Force Station’s Space Launch Complex-37 tomorrow, carrying a mission for the National Reconnaissance Office. This is the 16th and final launch of a Delta IV Heavy rocket. It was rescheduled after a nitrogen pipeline issue led to a scrubbed attempt more than a week ago. As of right now, the launch is targeted for 12:53pm tomorrow.
