How about filling each female connector with some sort of conducting
paste so that when the male pin is inserted, any gap is filled with that
conducting paste and thus there would be no air to freeze in there.

(Perhaps the paste could be mercury which would probably solidify once
that cold but still form a good bridge between the male pin and the
female cyclinder.

lets hope the lessons of the past have been noticed so whatever system
finally replaces shuttle has a minimum of these pesky problems.

I seriously doubt the current replacement will ever fly, new president
and congress will call for a re design. its too costly, too large a
capsule and rather than being a affordable replacement its a pork
piggie payoff. with funding as is we just cant afford a bloated piggie
squealing on the pad
