Video: Missile alert satellite launches atop Atlas 5

United Launch Alliance teams mounted a top secret payload for the National Reconnaissance Office on top of an Atlas 5 rocket Monday at Cape Canaveral in preparation for a liftoff scheduled just after sunset Nov. 3.

A Chinese Long March 4C rocket failed to place its top secret military payload into orbit Wednesday after a launch from the Taiyuan space base southwest of Beijing, according to the state-run Xinhua news agency.

The Atlas 5 rocket emerges from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station. Liftoff is set for Thursday at 5:55 p.m. EST.
