Following a scrub yesterday due to a boat breaking the range safety keep out area the Orbital Sciences Orb-3 mission made another attempt today. Following a very some and uneventful countdown the Antares rocket carrying the ‘Deke Slayton’ Cygnus lifted off on time at 6:22pm EDT, unfortunately approximately 6 seconds later a catastrophic failure occurred causing the rocket to explode and come crashing back to the launchpad.
Orbital Sciences have instigated a failure investigation team which will be led by Richard Straka, Deputy General Manager of Orbital’s Launch Systems Group. The investigation team will include representatives from NASA, Orbital, and the Mid-Atlantic Regional Spaceport in Wallops, Va.
Reports on NASA TV indicate significant damage to the launch pad and fires could be seen burn over a wide area after the explosion. All range personnel have been accounted for.
This is certainly a setback for Orbital Sciences, the Commercial Cargo program and the numerous science teams that had payloads on Cygnus, it shouldn’t have too much of an impact on future launches for the other suppliers to the station. However until the cause of the anomaly is known and resolved we seriously doubt there will be any further Cygnus launches to the station.
We will continue to update this post as further information becomes available.
