You know the problem with creationist astronauts is that the very act of launching oneself into the heavens would be seen as hubris and punishable by the almighty to them. One need only look at the story of the Tower of Babel to see what I mean.
Furthermore, the philosophy of creationism is incompatible with scientific curiosity. If God Did It why would we need to spend money going into space? That money could be better spent building more missions and on rigorous schools to study the Bible and nothing else.
