Orbital CRS-3 Update 10/30/2014

Launch Site Status:

Based on initial sweeps conducted by an Orbital safety team, it appears a significant amount of debris remains on the site and it is likely substantial hardware evidence will be available to aid in determining root cause of the Antares launch failure. Some of the Cygnus cargo has also been found and will be retrieved as soon as we have clearance to do so to see if any survived intact. After up close visual inspections by the safety team, it still appears the launch site itself avoided major damage. There is some evidence of damage to piping that runs between the fuel and commodity storage vessels and the launch mount, but no evidence of significant damage to either the storage vessels or launch mount. Detailed evaluations by MARS and their engineering team will occur in the next couple of days. An Orbital-led team has begun cataloging and documenting the location of all pieces of debris over the next several days after which the debris will be relocated to storage bays on the island for further evaluation.

Antares Data Review:

Telemetry data has been released to Orbital and our engineers presented a very quick look assessment to the Accident Investigation Board at the end of the day. It appears the Antares vehicle had a nominal pre-launch and launch sequence with no issues noted. All systems appeared to be performing nominally until approximately T+15 seconds at which point the failure occurred. Evidence suggests the failure initiated in the first stage after which the vehicle lost its propulsive capability and fell back to the ground impacting near, but not on, the launch pad. Prior to impacting the ground, the rocket’s Flight Termination System was engaged by the designated official in the Wallops Range Control Center.
