Would you leave everything you have here on Earth for a one-way ticket to Mars?  According to KSDK TV in St. Louis, well over 200,000 people have applied for the Mars One mission which is a privately funded mission to colonize Mars by 2025. 

According to Mars One, the cost of putting the first four people on Mars will be more than six billion dollars, and another four billion dollars for each trip that follows. Selling the rights to a possible reality show could raise part of the money.

Critics of the Mars One mission, including the head of NASA, who recently said he doubts enough money can be raised.
