It just missed falling back on the pad. I did a frame by frame analysis of
the NASA video. It shows one engine going fuel rich starting with yellow
exhaust changing to a yellow/red exhaust flame color followed by a fire in
the aft section. At 1 second into the event there is a bright flash from the
aft section coupled with a horizontal radial flame ejecting multiple parts
at high velocity.
To me, it appeared like a burn through in the duct between the turbine and
main combustion chamber changing the O/F mixture and chamber pressure. The
change in pressure across the turbine resulting in an over rev failure of
the turbine/pump assembly.
Regen cooling failure would also change the O/F mixture, but I would place
the duct failure at the top for elimination from the visual data I have.
Looking at the picture and the lack of debris, Orbital Science may be
limited to visual and telemetry data. I hope that the detonation wave just
distributed the debris over a larger area.

The Wallops Incident Response Team completed today an initial assessment
of Wallops Island, Virginia, following the catastrophic failure of Orbital
Science Corp.’s Antares rocket shortly after liftoff at 6:22 p.m. EDT
Tuesday, Oct. 28, from Pad 0A of the Mid-Atlantic Regional Spaceport at NASA’s
Wallops Flight Facility in Virginia.
“I want to praise the launch team, range safety, all of our emergency
responders and those who provided mutual aid and support on a
highly-professional response that ensured the safety of our most important
resource -- our
people,” said Bill Wrobel, Wallops director. “In the coming days and weeks
ahead, we'll continue to assess the damage on the island and begin the
process of moving forward to restore our space launch capabilities. There's no
doubt in my mind that we will rebound stronger than ever.”
The initial assessment is a cursory look; it will take many more weeks to
further understand and analyze the full extent of the effects of the
event. A number of support buildings in the immediate area have broken windows
and imploded doors. A sounding rocket launcher adjacent to the pad, and
buildings nearest the pad, suffered the most severe damage.
At Pad 0A the initial assessment showed damage to the transporter erector
launcher and lightning suppression rods, as well as debris around the pad.
The Wallops team also met with a group of state and local officials,
including the Virginia Department of Environmental Quality, the Virginia
Department of Emergency Management, the Virginia Marine Police, and the U.S.
Coast Guard.
The Wallops environmental team also is conducting assessments at the site.
Preliminary observations are that the environmental effects of the launch
failure were largely contained within the southern third of Wallops
Island, in the area immediately adjacent to the pad. Immediately after the
incident, the Wallops’ industrial hygienist collected air samples at the
Wallops
mainland area, the Highway 175 causeway, and on Chincoteague Island. No
hazardous substances were detected at the sampled locations.
Additional air, soil and water samples will be collected from the incident
area as well as at control sites for comparative analysis.
The Coast Guard and Virginia Marine Resources Commission reported today
they have not observed any obvious signs of water pollution, such as oil
sheens. Furthermore, initial assessments have not revealed any obvious impacts
to fish or wildlife resources. The Incident Response Team continues to
monitor and assess.
Following the initial assessment, the response team will open the area of
Wallops Island, north of the island flagpole opposite of the launch pad
location, to allow the U.S. Navy to return back to work.
Anyone who finds debris or damage to their property in the vicinity of the
launch mishap is cautioned to stay away from it and call the Incident
Response Team at 757-824-1295.
Further updates on the situation and the progress of the ongoing
investigation will be available at:
