The launch of a United Launch Alliance Atlas V 551 rocket carrying the Space Test Program-3 (STP-3) mission for the U.S. Space Force’s Space Systems Command (SSC) has been scrubbed. The team repaired the ground storage system but will require additional time to verify the sample integrity of the fuel prior to tanking operations. Launch is now scheduled for Tuesday, Dec. 7 at 4:04 a.m. EST.
