The NROL-35 Atlas 5 launch by the numbers.

The United Launch Alliance Atlas 5 rocket unleashed two million pounds of thrust at 7:19 p.m. PST (10:19 p.m. EST) on Dec. 12 to blast off from Vandenberg Air Force Base in California on the NROL-35 mission. See photos of the launch from the press viewing site.

There’s a new launch being added to Vandenberg Air Force Base’s schedules — another Delta 4 rocket flight for the National Reconnaissance Office.
