Orion Launch from UCS-3

A Delta IV Heavy rocket roars to life at Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The launch vehicle is carrying NASA's Orion spacecraft on an unpiloted flight test to Earth orbit. Liftoff was at 7:05 a.m. EST. The flight will send Orion 3,600 miles in altitude beyond the Earth's surface on a four-and-a-half hour mission.
