Gallery: Antares rocket explodes

The Orbital ATK’s Cygnus commercial resupply spacecraft, named the SS Deke Slayton II, is packed up and poised for launch to the International Space Station.

Orbital ATK’s seventh Antares rocket stands ready for launch with a Cygnus supply ship Saturday on a two-day flight to the International Space Station.

Bidding farewell to the International Space Station today, the commercial Cygnus cargo ship separated to a safe distance before igniting an intentional fire in microgravity like never before, all in the name of science.
