Any reason why the foam cannot be *inside* the fuel tank?

Because if anything came off, for any reason, it would go into the
SSME?
I suspect that could spoil your whole day.

Liquid oxygen soaked into an organic material is an explosive.
So any internal insulation in the oxygen tank would have to
be non-organic.


In principle, you could immerse the LO2 tank in the LH2 tank, and insulate
the outside of the LO2 tank.

You know, that's an idea I don't think I've seen before. It's interesting
if nothing else.
