NASA space scientists have been studying giraffe skin so they can apply what they learn from it to the construction of spacesuits.

One of the problems with science fiction, which is probably one of the reasons why I haven't done one for many, many years, is the fact that everything is used up. Every type of spacesuit is used up, every type of spacecraft is vaguely familiar, the corridors are similar, and the planets are similar.

We found out the Gemini spacesuit was well oxygen was flowing to keep me cool as well as to breathe and it wasn't good enough. My visor got fogged.
