31 - "Are there any Freepers who can supply an explanation for what we see happening?"

More NASA incompetence.

I think we would do better putting a 6 year old StarTrekkie in charge.

Seems like FIRST thing to do would be to isolate each compartment - THAT immediately tells which eqpt''s it CAN'T be.

Sure, an "outside" bubble check isn't practical - can't "paintbrush" soapy water solution in a vacuum, best I can tell, even if it could be done to coat the whole exterior of the thing coating every joint.

But an outside IR camera, aimed back at the single compartment in darkness, should reveal a "trail" of gasses from one or more joints or seals or connections.

And are you sure you want to randomly "paint (er, contaminate with water) joints designed to be pure and pristine in a space environment?
