I've been thinking a lot recently about space exploration and colonization, and the big question that's been running through my head has been this: would I be willing to leave everything on Earth behind and go to Mars, even if there was a strong possibility that I would never return home?
Wondering what everyone here on Tildes thinks about that question.
