So a mist of liquid would work about as I thought it would...nice to
know.
Big pustuales (sp?) on the sides of S'v bioships...an interesting
image...

 I based this idea on Brin's book (as mentioned) and on stuff I've read
from the Apollo & other space programs where ice crystals have been
observed from outgassed atmosphere, ejected material, etc.

AFAIK, the shuttle (and the rest of the stuff in orbit) has more probs
with the sun's heat than internal heat. With no atmosphere, the sun's
heat
can be brutal. While the shadow parts of a craft can be vacumn-cold -
which can lead, I've read, to terrible strains on the structural
integrity. (Heating expansion/contraction of the metal isn't even for
the
structure, for starters)
