In my opinion and at this time people should not be flown into space instead of robots because of the huge expense of life support. The amount of funds that can be saved and put toward further exploration and scientific discovery is the only reason that I believe sending people to space is a waste of very tight funding.
People should not be flown to space instead of robots. Just like the stealth manless flyers hunt down terrorists because of the lack of a life to be sacrificed. Only after the robots have tested the unexplored trenches of dangerous space travel should people be allowed to fly to space.
