Photos: Atlas 5 rocket soars from West Coast

Delays have set up the possibility of up to three rocket launches this weekend from different pads along Florida’s Space Coast, including two SpaceX missions on Sunday that could set a company record for the shortest span between two Falcon 9 rocket launches. But in the world of ever-changing launch schedules, numerous factors such as weather and technical issues could thwart launch plans this weekend. 

This photo gallery shows the U.S. Navy’s third Mobile User Objective System (MUOS) satellite being encapsulated in the rocket’s nose cone and being lifted atop the Atlas-Centaur vehicle. Liftoff is planned for Jan. 20.

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Thursday to begin a pursuit of the International Space Station.
