The launch date for a United Launch Alliance Atlas V carrying NROL-79 for the National Reconnaissance Office is under review. The team is actively working to resolve Atlas V second stage booster issues discovered during vehicle testing. This additional time will allow the ULA team to ensure all systems are operating nominally prior to launch. A new launch date will be released once it is established. The Atlas V is set to lift off from Space Launch Complex-3 at Vandenberg air Force Base in California.
 
The Atlas V SBIRS mission remains on schedule for Jan. 19 from Cape Canaveral Air Force Station in Florida, pending final vehicle verifications.
