The Mars Underground. If you have free time tonight or tomorrow, watch this amazing documentary that explains how we can get to Mars soon and colonise it.
As James Cameron puts it:
This film captures the spirit of Mars pioneers who refuse to let their dreams be put on hold by a slumbering space program. Their passionate urge to walk the soil of an alien world is infectious and inspirational. This film is the manifesto of the new space revolution.
Perhaps you have seen it already -- it was released two years ago -- but if you haven't, it's an uplifting and fairly realistic look at what we can do to get there and transform the Red Planet into another Earth.
Too bad the people with the money are not interested in any of this.
