Many expeditions to the “Unknown” ended gruesomely because they didn’t know and were not prepared; While going to these places today one has a very good chance to survive. I can only assume it will be the same with space explorations (once we’ll get there). The first trips will have extremely poor surviving rates but later you might as well go there with your class field trip.
