So NASA is talking about one-way trips to Mars, because the difficulty with getting to Mars is getting back. But who do we send? Then consider the jail debate: we have some prisoners on death row that we're just going to execute. It seems like two problems with one solution, where we turn Mars into a prison planet. The bonus is a new reality TV show, too. The unintended side-effect? Only one guy arrives alive at Mars, wearing a necklace made of ears.

PS - In reality, a one-way trip to Mars will probably be even more expensive.
PPS - Because after a few years, you have to send a rescue mission.
