Reporters run for cover as Antares rocket explodes

Watch the post-launch news conference from the Kennedy Space Center following the successful launch of an Atlas 5 rocket on December 6, carrying the Orbital ATK Cygnus cargo ship bound for the International Space Station.

A two-stage Northrop Grumman Antares rocket rolled out of its horizontal integration facility Monday for the mile-journey south to launch pad 0A at the Mid-Atlantic Regional Spaceport in Virginia, where liftoff on a space station resupply mission is scheduled for Wednesday.

A hundred days after the last U.S. commercial resupply of the International Space Station by a Cygnus cargo ship launched atop an Atlas 5 rocket, the booster and freighter duo will do it again Tuesday.
