Sounds like another reason for bold aside from wind violation. Still waiting to hear why.av Nicole Mortillaro via twitter 12/4/2014 1:10:36 PM

You know, soon I'll be able to recite the countdown go/no-go list myself.av Nicole Mortillaro via twitter 12/4/2014 1:25:03 PM

Sounds like they will try to cycle the valve to see if it closes. Did not close all the way.av Nicole Mortillaro via twitter 12/4/2014 1:27:21 PM

This is Randy Attwood in Mississauga. These delays are frustrating of course - especially for Nicole and Aarti. I am reminded of the saying astronauts use during long holds as they sit on the launch pad - "I would rather be on the ground, wishing I was in space than in space, wishing I was on the ground!" You don't proceed until everything is good to go. Launch rules are written months ago when there isn't the "GO FEVER" - everyone wants to light the candle now but it is best to wait for all weather and technical issues to be resolved. -
In the Space Shuttle days, especially since 1998 when the shuttles visited and built the International Space Station, there was a very short launch window - 10 minutes in fact. This was because the shuttle had to launch into the plane of the ISS orbit. You can think of it as a track the ISS is on - it takes tremendous energy to change the plane of your orbit. So if this were a shuttle - or an unmanned cargo mission to the ISS, we would be standing down and trying again tomorrow.
-
There is 1 hour left in the launch window - 1 hour left to get off the ground or recycle to tomorrow. The launch window is determined based on various reasons - lighting in the launch and landing areas, the flight path of the Orion, many different variables which determine how long we will sit here and try to launch. Weather for tomorrow looks worse than today - so hopefully the technical problems will be solved and we will go soon.
-
The fill and drain valves are closed so that the liquid oxygen and hydrogen fuel tanks can be pressurized for launch. They have seen this in the past on previous Delta 4 Heavy launches, they used a workaround successfully then and they are implementing that now - essentially opening and closing the valves 5 times each to ensure they work properly. LOX cycles look good on all three cores - working the hydrogen valves now
