Launch is scrubbed until early next year, as there is a structural issue with the 1st stage fuel tank that will require repair.
I will provide further comment as soon as this has been carefully analyzed. Consistent with our policy, we must be 100% green for launch with no outstanding concerns whatsoever. It is not just a matter of repairing the damage, but also understanding at a fundamental level how to ensure it never happens again.
We will also do another full review of all the vehicle systems, including propulsion, structures, avionics, software and ground support systems. Therefore, I expect that the earliest that launch would occur is late January.
Third time's the charm.

Due to high winds, we placed the countdown on hold and began draining the fuel tank. As we drained fuel from the 1st stage tank, a faulty pressurization valve caused a vacuum condition in the tank.
This caused a fuel tank barrel section to deform and suck slightly inward. It is important to note that the root cause is an electrical fault with a valve, not structural design.
At this point, it appears that no other damage was sustained to the vehicle or the satellite. The rocket will be lowered down this afternoon and placed in its hangar for further inspection.
