The worst environment for the tank was, believe it or not, PROOF pressure testing on the ground and then during its ride launch aboard a Titan IV in 1997.

Lessee... Do I believe that proof pressure testing (250%?) in an oxidizing atmosphere under one gee or being kicked upstairs under umpteen gees through an oxidizing atmosphere is tougher than coasting through flat space? Um. No. You are correct about the toughest conditions.

BTW, did you guys put a slow spin on it to alleviate thermal stresses? I know they are tiny, but they build up.

Just a science junkie asking questions. ;>) Congrats again.

BTW, what would a cook know about thermal stresses on thin-walled pressure vessels? Harumph. Ignore me... 8>)

Actually I meant, 'Um... yes.' I think.

Sometimes I transpose things... which is why I'm not a rocket scientist... ;>)

Testing on earth is tougher than space is the point I was trying to get across. Oxidizing atmosphere, 1 gee, all of that.

I'm tired again. And it's beginning to show.

LOL!!! Obviously, this 'science junkie' cook as a great handle on these things. Believe you me, I don't know if they put a slow spin on it. The tank is buried and covered with heaters and thermal blanket. Other components might require the slow spin, tho.
