When Robert Zubrin published his classic book The Case for Mars a quarter century ago, setting foot on the Red Planet seemed a fantasy. Today, manned exploration is certain, and as Zubrin affirms in The New World on Mars, so too is colonization. We will settle on Mars, and with our knowledge of the planet, analyzed in depth by Dr. Zubrin, we will utilize the resources and tackle the challenges that await us. What we will we build? Populous Martian city-states producing air, water, food, power, and more. Zubrin's Martian economy will pay for necessary imports and generate income from varied enterprises, such as real estate sales-homes that are airtight and protect against cosmic space radiation, with fish-farm aquariums positioned overhead, letting in sunlight and blocking cosmic rays while providing fascinating views. Zubrin even predicts the Red Planet customs, social relations, and government that will overcome traditional forms of oppression to draw Earth immigrants. With all of this in place, Zubrin's Red Planet will become a pressure cooker for invention, benefiting humans on Earth, Mars, and beyond. We can create this magnificent future, making life better, less fatalistic. The New World on Mars proves that there is no point killing each other over provinces and limited resources when, together, we can create planets.
