The launch of the Atlas V 551 carrying the Space Test Program (STP)-3 mission for the U.S. Space Force’s Space Systems Command (SSC) has been delayed to Dec. 6 at 4:04 a.m. Eastern due to a leak in the Rocket Propellant (RP)-1 ground storage system. The mission is set to launch from Space Launch Complex (SLC)-41 at Cape Canaveral Space Force Station, Florida.
