Flying the second of back-to-back launches for the National Reconnaissance Office, Rocket Lab placed a classified U.S. government payload into orbit Thursday after a liftoff from New Zealand. It was the third Electron rocket flight in less than six weeks, the busiest stretch of missions in the Rocket Lab’s history.
