Maybe HipShot can answer that question, it IS his field, after all....or was before he retired. My observation might be to go back to the early days of the US Space Program, say Mercury or Geminii. How long did they let those birds sit on the pad before scrubbing a mission. I recall that one of them was forced to go to the bathroom in his suit rather than break him out of the capsule to find a facility. That bird flew, too. I guess it was Sheppherd and after he "went" they lit the candle!
It's probably already too late, assuming they were fueled and ready to go at 1am est last night. Upthread the time-window was listed as 48 hrs but who knows how nk enginering works with rocket tanks. The only thing we know for sure is that some nk engineers are now very nervous. LOL.
I read somewhere that they have 48 hours from the time they fuel the thing until the time when the acidic fuel begins to degrade the missile...... don't know how fast or how severely that problem develops but they may not have many more hours to decide to launch it or else risk catastrophe when they do try to launch it and it blows up. Would be NICE if we had some way of making it blow up for them..........
Dan(9698) is an ex-missile guy. He might be able to answer this one.
