    Black body radiation for cooling in space

    Black body radiation for cooling in space Since we all know, not just as Big E. told us, that in space we need no water to cool our systems. Additionally, we do not have lots of it there. Normally. So we have to get some nice formula to calculate how fast our space ship can cool down when...

    Physicists from Germany, fascinated by Dr. Zubrin's visions for many years.

    For many years, I have been interested in space travel as a hobby (I have been working as a physical systems modeler in the automotive industry for decades). I have been particularly fascinated by Dr. Robert Zubrin's missions to Mars. I have been investigating a variant for the colonization of...
