Reporters run for cover as Antares rocket explodes

United Launch Alliance has begun stacking its first Atlas 5 rocket to fly in service to the International Space Station, a commercial mission to send supplies to the orbiting complex.

The ocean-sailing ship that transports rocket stages from United Launch Alliance’s factory to U.S. launch sites completed its latest voyage overnight, pulling into port to deliver the Atlas 5 that will send a cargo freighter to the International Space Station in March.
