Within a few years, humans will be able to voyage to Mars. We will settle the red planet, transforming its raw materials into resources and tackling the challenges that await us, creating a new frontier for humankind. Dr Robert Zubrin explains how populous Martian city-states will emerge, producing their own air, water, food, power and more. How they must be beautiful to attract settlers, and what that might look like. How the primary exports are unlikely to be material goods but intellectual products, created by a technically adept population in a frontier environment where people will be forced to innovate – including GMOs, robotics, AI and power production. Zubrin even predicts the red planet’s customs, social relations and government – of the people, by the people, for the people, with inalienable individual rights – that will overcome traditional forms of oppression to draw talented Earth immigrants.
