Colonize Mars. The great theme of science fiction, the Dutch foundation March One wants to give it body. She plans to send, from 2024, 24 men and women on the red planet, a journey of no return.

Objective: to live on a planet with no atmosphere, exposed to cosmic rays, with traces of ice as a water supply, and average temperatures around -60 ° C. ..
It is a beautiful dream, that will be really difficult to achieve. Who says colonize a planet says send an extremely heavy infrastructure : housing units and work vehicles , ground transportation, equipment for crops, a plant for energy, but also any device to extract water from the soil Mars. Participants can build anything there.
The amount of water necessary for a person is considerable . For example, a French consume more than 100 liters of water per day . It therefore can not be brought from Earth . To validate the extraction of subsurface ice concept for drinking, eating , showering , it is essential to implement a prior probation experience.
We know that the ice is in the soil , but it was never retrieved. The exploitation of resources, especially water , is under study. In 2008, the Phoenix lander sent to the planet tried mining for ice but did not succeed because the ice and soil were extremely hard .
