Gallery: Antares rocket explodes

The debut launch of an upgraded version of Orbital ATK’s Antares rocket has slipped to Friday after ground teams resolved a minor vehicle issue and made emergency preparations for Hurricane Matthew, which bypassed the Antares launch site on Virginia’s Eastern Shore this weekend.

The Japanese space agency has delayed the planned Sept. 30 launch of an HTV space station cargo ship to repair a leak in the vehicle, clearing the way for Orbital ATK to slip the launch of its Cygnus supply ship from Aug. 22 to the second half of September to complete tests and analysis of its re-engined Antares rocket, officials said Wednesday.

The two structural elements of Orbital ATK’s OA-7 Cygnus space freighter were delivered to Kennedy Space Center for final assembly, the packing of cargo and launch to the International Space Station.
