They do not send bad stuff in space. It has to be proven reliable. A well known operating sysem would never go in space. And a weel known "free" competitor of the previous no more. VxWorks... is it possible to buy it and install on my PC?


The languages too are an important issue. When I worked in the domain I knew that the old C was not allowed, due to memory management problems, well known from C designers who are sometimes confrontated to "unexplainable malfunctions".

As explained in the article, radioactivity too is a major problem. I remember have seen big TO3 transistors destroyed with just one ion, or a SPARC microcontroler (sun stations) sending strings of errors from radiations.
