US: The launch of three US Air Force space surveillance satellites has been postponed for the second time in the past few days. According to a United Launch Alliance spokeswoman the delay was because of weather conditions this time. The trio of satellites comprising the Air Force Space Command (AFSC)-4 mission was scheduled to lift off from Cape Canaveral Air Force Station in Florida aboard a ULA Delta 4 rocket. But the weather never cleared enough during a 65-minute window.
According to ULA spokeswoman Jessica Rye, the postponement followed a delay July 23 caused by an issue with the ground support equipment environmental control system that supports the launch vehicle. ULA has rescheduled the launch for July 25, although weather forecasts only show a 40% chance of favorable conditions then, she said. The primary payload onboard the Delta 4 are two satellites that will serve as the first-generation of the Geosynchronous Space Situational Awareness Programme, a previously classified space surveillance system first disclosed in February by Gen William Shelton, commander of Air Force Space Command.
The rocket will also carry the Automated Navigation and Guidance Experiment for Local Space, or ANGELS, satellite.
