Rocket Lab launches US spy satellite on mystery mission

Another U.S. spy satellite has taken flight on a mystery mission. The U.S. National Reconnaissance Office's (NRO) NROL-199 spacecraft launched today (Aug. 4) atop a Rocket Lab Electron booster from New Zealand, rising off the pad at 1 a.m. EDT (0500 GMT; 5 p.m. local time in New Zealand). If all goes according to plan, Rocket Lab will deploy the satellite about an hour after liftoff. The launch occurred about two days later than planned after high winds delayed an attempted liftoff on Aug. 2. Rocket Lab shut down its webcast shortly after the Electron reached orbit at the request of the NRO. More
