Gallery: Antares rocket explodes

A year after a launch mishap left Orbital ATK’s Cygnus supply ship without a ride to the International Space Station, company officials say the cargo delivery system is on the verge of a comeback, thanks to deals with United Launch Alliance and a decision to redesign its Antares booster with new rocket engines.

Orbital ATK ground crews in Virginia are fueling the next Cygnus cargo freighter this week for launch toward the International Space Station in mid-October on the first flight of the company’s upgraded Antares rocket in two years.

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a two-day pursuit of the International Space Station.
