On December 06, 2013 at 07:14 UTC the "Atlas-5” rocket-carrier was launched from Vandenberg Air Force Base, the spaceport on California's Central Coast, USA. The rocket orbited a US classified spy satellite. The satellite is owned by the National Reconnaissance Office, but government officials do not disclose the identities of the NRO's spacecraft, only saying the payload will serve national security purposes. But independent satellite-watchers believe the spacecraft will join the NRO's fleet of spacecraft with radars to penetrate cloaks of clouds and darkness and reveal what adversaries are doing regardless of weather or time of day. The mission is officially named as NROL-39.
