In the 2020s, Mars One -- essentially a Dutch-made extraplanetary reality TV show -- will send amateur astronauts on a one-way trip to Mars. The Mars One mission, according to a new report by aerospace researchers at MIT, might make for particularly morbid viewing: Analyzing the Mars One mission plan, they found that the first astronaut would suffocate after 68 days. The other astronauts would die of starvation, dehydration, or incineration in an oxygen-rich atmosphere.
