Gallery: Antares rocket explodes

A Northrop Grumman Antares rocket and Cygnus cargo carrier climbed into orbit Saturday from Wallops Island, Virginia, in pursuit of the International Space Station with more than 7,200 pounds of research hardware and provisions, the second supply ship launch to the space station in less than 24 hours.

A commercial Cygnus supply freighter will transport a motley mix of experiments to the International Space Station, helping scientists engaged in a range of research disciplines from studying the birth of the solar system to helping astronauts survive marathon missions in space.

This is the pre-launch news conference held Dec. 2 at NASA’s Kennedy Space Center for liftoff of the Orbital ATK commercial Cygnus cargo ship aboard a United Launch Alliance Atlas 5 rocket for the International Space Station.
