The launch of a United Launch Alliance (ULA) Atlas V rocket carrying the NROL-101 mission for the National Reconnaissance Office is now planned for Nov. 4, 2020, at 5:54 p.m. EST.
The Atlas V was rolled to the pad today for final launch processing. Upon arriving at the launch pad we experienced an upper payload environmental control system flow rate reduction. The team is in the process of rolling the Atlas V back to the vertical integration facility (VIF) to complete troubleshooting. The vehicle and payload are healthy.
