United Launch Alliance ground crews on California’s Central Coast are gearing up to send a classified U.S. government spy satellite into orbit as soon as Monday — weather permitting — aboard one of the company’s four remaining Delta 4-Heavy rockets.

United Launch Alliance’s next launch attempt for its Delta 4-Heavy rocket from Cape Canaveral with a top secret U.S. government spy satellite will be delayed to no earlier than early Tuesday.

Meteorologists are anticipating favorable odds of good weather during the countdown to launch an Atlas 5 rocket and U.S. military satellite on Thursday evening from Cape Canaveral.
