Mars; the final frontier.
...if you plan to be one of those Mars One colonists. For humanity at large, it's approximately the third frontier, depending on whether you start counting with John Glenn's sub-orbital flight. Or the fourth frontier, if you start with those Russian dogs and monkeys.
Who would want to do this? This woman seems perfectly sane.
On the other hand, a British paper reported the rumor that some of the colonists plan to grow weed and bogart the whole planet. That actually would make a great movie.
What happens, however, when faster ships are developed in ten or twenty years? Or are they counting on that?
