Video: OA-7 Cygnus freighter arrives at its orbital destination

United Launch Alliance crews at Cape Canaveral have topped off an Atlas 5 rocket for liftoff Monday with the U.S. military’s next infrared sentinel to join a satellite fleet designed detect missile launches around the world.

A Soyuz booster set for liftoff Wednesday with a Russian cosmonaut, a German flight engineer, and a former NASA flight surgeon heading for the International Space Station arrived at its launch pad in Kazakhstan Monday.

Rolling toward a mid-May deployment of a clandestine spy satellite, United Launch Alliance’s triple-body Delta 4-Heavy rocket moved from its Cape Canaveral assembly building to pad 37B yesterday.
