Too bad space flight in real life is probably limited to rockets to get up there - no "reactionless drive" flying saucers. And then rockets, solar sails, or "nuclear pulse propulsion" (Project Orion) to get anywhere. Seems antimatter is ridiculously expensive, warp drive doesn't work, that black hole thing uses too much energy, and even the Bussard ramjet looks impossible. Which means sending robots out there and launching manned missions to orbit is hard, manned missions to the moon are even harder, who knows if manned interplanetary flight can be done, and it looks like slower-than-light interstellar travel is near or at impossible for biological life.
I used to think that money and politics were holding space travel back - and they could be - but the more I learned about how space travel works in real life, the more I can see why there doesn't seem to be much progress in it. If space travel were easier, companies and even private citizens could be doing it more by now.
edit to add: lol I forgot I already posted in this thread earlier
