ULA And USAF Successful Launch At Last! And Celebrates A Golden Anniversary
Before this evening's launch the most recent delay was as a result of during the final seconds of the launch countdown, an anomalous data signature with the thrust vector control system on one of the two solid rocket motors mounted to the Delta IV booster was detected.
