A Delta IV rocket carrying a national security satellite successfully launched from Vandenberg Air Force Base Friday afternoon.
Mission NROL-47 took off at Vandenberg’s Space Launch Complex-6 near the Pacific Ocean, about 10 miles west of Lompoc.
The United Launch Alliance rocket carrying a National Reconnaissance Office payload was supposed to launch Wednesday but was rescheduled for Thursday, then delayed multiple times and finally scrubbed due to a ground system valve problem.
The rocket launched Friday 2:11 p.m. after another delay following an initial 1 p.m. launch time. NROL-47 marks United Launch Alliance’s 27th launch for the federal National Reconnaissance Office.
It’s the 36th flight for a Delta IV rocket since the first in 2002, according to the company’s website.
