I have mentioned before that we should forget about sending people to Mars for the time being, and just send robots. For the same reason UFOs aren’t extraterrestrials; space travel is incredibly difficult and dangerous.

Space is an extremely hostile place actively trying to kill you, making interplanetary travel so difficult and dangerous there isn’t a good reason to attempt it anytime soon, never mind interstellar travel.
