Mars One will establish a permanent human settlement on Mars. Crews of four will depart every two years, starting in 2024.
A key part of the success of such a mission seems to rely on the following:
On Mars, water can be extracted from the soil.
This will supposedly give them everything they need in terms of water, oxygen and food production.
This organization also solicits donations from the public to fund their 'mission to mars'. That's just ten years from now.
Is this scientifically viable?
