Orion EFT-1 Launch Scrubbed for Today (Update)

Keith's note: Today's attempt to launch Orion EFT-1 has been scrubbed today after continuing issues with ground winds - and then with fill and drain valves on the Delta IV Heavy Launch vehicle. There were also issues with battery levels on the rocket's video system. The plan seems to be to try again tomorrow with a 7:05 am ET launch time.

Keith's update: According to speakers at today's NASA press briefing, the ship that caused the launch delay was never in a position to present a safety hazard. While winds caused the first two scrubs, the ultimate scrub for the day had to do with sluggish response times for liquid Hydrogen valves on the Delta IV Heavy. This is an issue that has been seen before on a prior launch. There are also some minor issues having to do with battery life for instrumentation inside of Orion and inside the Delta IV Heavy rocket that are being addressed. If a launch attempt is made tomorrow but is not successful, then ULA will need to skip over Saturday in order to replenish ground tanke supplies. Overall the tone of the briefing was that this all went by the books, the issues are understood and can be handled.
