Hi All,
I could start writing all kinds of angry E-mails, but I have always

I'm glad the AMSAT-BB is not reflecting the great community that is amateur

Hummh,
We get an equilibrium of a cube to be about 55F (13C) when exposed to the
sun on one side and all the other sides radiating to cold space. (assuming
they are thermally connected).
I wonder why the big difference between our calculations?
