Mars One

A team of engineers at that studies the technology needed for humans to live on other planets has determined that the One to send four people to colonize the Red Planet by 2025 is not possible. 

“The claim they make is that no technology is required for their mission,” said Syndey Do, a doctoral candidate in aeronautics and astronautics at MIT and the lead author of the study. “Our numbers that is not feasible.”

Mars One is a nonprofit organization based in the Netherlands that has boldly promised the world to send four people on a one-way trip to Mars by 2024, with an additional four people arriving every two years.

To finance the mission, the Mars One team has proposed a reality TV show in which 40 aspiring astronauts from around the world would compete to be the first people to settle on Mars. 

The MIT team was already at work on building what they call a “settlement-analysis tool” (it’s a computer model) that would help them understand what was needed for humanity to live on another planet. After chatting about the Mars One project in their office one day, they decided to use their tool to see whether the Mars One plan had legs.

To test the feasibility of Mars One’s plan to have colonizers grow all their food, the team built a simulated Martian habitat, put in data on how crops grow in space and then put in ideal growth conditions. Even with those ideal conditions, the Mars One would an area four times larger than the one it had , they said.

Andrew Owens, another of the MIT team, looked at how many spare parts would need to be brought to the planet to keep the colony functioning. He determined that over time, replacing failed parts would get very costly and would take up an amount of space in spacecraft that were also supposed to transport people.

In the end, they determined that it would be cheaper to send people to Mars on a round trip, rather than keep them there for years.

Before you start accusing the MIT engineers of wet blankets, consider that these guys go to work every day and try to figure out how to make Mars colonization possible.

Owens put it this way in an with The Times: “It’s not that Mars colonization is infeasible; it is just that technology development will be required to make it feasible.”  
We’ll get there one day!
