^^ I'm skeptic about this Mars One. Even its leading supporter, Gerard ’t Hooft, the Dutch Noble laureate and ambassador for project doubted the mission plan. You would even raise an eyebrow if you know Mars One has a core staff of only three people: Norbert Kraft, chief medical officer; Arno Wielders, chief technical officer, and Bas Lansdorp, CEO.

yhokz101 what you've read about astronaut would suffocate after 68 days was actually the independent feasibility study done by MIT on Mars One mission plan.
