Mars One recently announced that they have narrowed down the candidates for the potential colonization of Mars to just 100 individuals. Ultimately, the company plans on launching 4 individuals into space in the next few decades and staging a reality television show on the Red Planet. Some people are (perhaps understandably) skeptical of the feasibility of this enterprise. After all, we haven't even set up a base on the moon yet. In fact, we haven't even been to the moon is decades. As such, some argue that a colony on the moon is a lot more realistic; others argue that even a moon colony is out of our reach.
What do you think? Can we make it to the moon? What about Mars?
