Gallery: Antares rocket explodes

Space station resupply missions launched from Virginia are set to resume in March 2016, after Orbital ATK integrates newly-built rocket engines into the Ukrainian-made booster stage of the company’s commercial Antares rocket and puts it through an on-pad test firing in January.

Officials from NASA, Orbital ATK, Wallops Flight Facility and the Commonwealth of Virginia preview Sunday night’s flight of the Antares rocket during the pre-launch news conference held on the eve of liftoff.

Engineers erected a commercial Antares rocket vertical on its launch pad on Virginia’s Eastern Shore Friday, positioning the 13-story booster for liftoff Sunday night with more than 5,000 pounds of supplies and experiments for the International Space Station.
