Be part of the first
settlement on Mars
Mars One aims to establish a permanent human settlement on Mars. Mars is the only planet we know of that can currently feasibly support human life and will be humankind's first step to become a multiplanetary species. Mars One's crews will go to Mars not to simply visit, but to live, explore and create a second home for humanity. The first men and women to go to Mars are going there to stay.
After the Earth, Mars is the most habitable planet in our solarsystem due to several reasons: Its soil contains water to extract it isnt't too cold or too hot. It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation.
Before carefully selected and trained crews will depart to Mars, several unmanned missions will be completed, establishing a habitable settlement waiting for the first astronauts to arrive.
The Sun is a reliable, robust and plentiful energy source. Using solar panels is the best choice for Mars One since it takes away the requirement to develop and launch a nuclear reactor, thereby saving time and money while avoiding the risk and concerns of use of a nuclear power source.
