DULLES, Va.Oct. 28, 2014--
Orbital
Sciences Corporation (NYSE:ORB), one of the world s leading space
technology companies, confirms that today s Antares rocket launch from
NASA s Wallops Flight Facility was not successful. Shortly after
lift-off from the Mid-Atlantic Regional Spaceport Pad 0A at 6:22 p.m.
(EDT), the vehicle suffered a catastrophic failure. According to NASA s
emergency operations officials, there were no casualties and property
damage was limited to the south end of Wallops Island. Orbital has
formed an anomaly investigation board, which will work in close
coordination with all appropriate government agencies, to determine the
cause of today s mishap.
It is far too early to know the details of what happened, said Mr.
Frank Culbertson, Orbital s Executive Vice President and General Manager
of its Advanced Programs Group. As we begin to gather information, our
primary concern lies with the ongoing safety and security of those
involved in our response and recovery operations. We will conduct a
thorough investigation immediately to determine the cause of this
failure and what steps can be taken to avoid a repeat of this incident.
As soon as we understand the cause we will begin the necessary work to
return to flight to support our customers and the nation s space
program.
Orbital will provide more information as it becomes available and is
verified.
