Gallery: Antares rocket explodes

Northrop Grumman is gearing up for up to four launches this year at Wallops Island, Virginia, including two launches with Cygnus cargo ships heading to the International Space Station, and a pair of Minotaur rocket flights carrying classified payloads into orbit for the U.S. government’s spy satellite agency.

Powered by two Russian-made RD-181 main engines, a Northrop Grumman Antares rocket fired into a mostly sunny sky Saturday afternoon over Virginia’s Eastern Shore carrying nearly 7,500 pounds of equipment to the International Space Station.
