Gallery: Antares rocket explodes

Managers aborted liftoff of a commercial Antares cargo launcher Saturday when an aircraft strayed into restricted airspace near the rocket’s planned flight path east from Virginia’s Eastern Shore.

Watch the post-launch press conference held at the Kennedy Space Center following the successful launch of an Atlas 5 carrying Orbital ATK’s Cygnus AO-6 cargo craft, which is headed to the International Space Station.

With investigators zeroing in on a decades-old rocket engine as the cause of a catastrophic launch mishap, Orbital Sciences officials said the company plans to use other launchers to send cargo to the International Space Station while modifying its Antares rocket with a new propulsion system.
