Falcon 1 Launch Delayed Until 2006

An anonymous reader writes "Florida Today is reporting that SpaceX will have to wait until 2006 to launch their Falcon 1 rocket that was scheduled for today. Engineers called off the launch when they noticed structural problems with the first-stage tanks. From the article: 'The Falcon 1 was to be launched from the U.S. Army's Ronald Reagan Ballistic Missile Defense Test Site on Kawajalein Atoll in the Pacific Ocean. Its payload: an $800,000 space research satellite that was built by cadets at the U.S. Air Force Academy.'"

The linked article isn't very informative. More information can be found here and here. a brief history of the company can be found here and a brief readout of this particular rocket can be found here.

Damage From Faulty Valve Causing Vacuum in a Tank

[Somegeek]

An update on Spacex's website gives the apparent cause of the damage:

"Posted December 19, 2005 at 4:40 p.m. California time: Here is the apparent cause of structural damage (further analysis may change the conclusion):

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 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. --- Elon ---"

It's a little disconcerting that a "structural" problem would be found only 15 minutes before the launch. The only thing I can think of off hand that makes sense is something related to fueling the rocket.

Actually, the problem was in draining the rocket. From the official update page:

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 inward. It is important to note that the root cause is an electrical fault with a valve, not structural design.
