Weinersmith as they dive into their book, A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through?

Earth is not well. The promise of starting life anew somewhere far, far away—no climate change, no war, no doomscrolling—beckons, and settling the stars finally seems within our grasp. Or is it? Critically acclaimed, bestselling authors Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of research, they aren’t so sure it’s a good idea. 

In a world hurtling toward human expansion into space, A City on Mars investigates whether the dream of new worlds won’t create nightmares, both for settlers and the people they leave behind. In the process, the Weinersmiths answer every question about space you’ve ever wondered about, and many you’ve never considered:

Can you make babies in space? Should corporations govern space settlements? What about space war? Are we headed for a housing crisis on the Moon’s Peaks of Eternal Light—and what happens if you’re left in the Craters of Eternal Darkness? Why do astronauts love taco sauce? Speaking of meals, what’s the legal status of space cannibalism?

With deep expertise, a winning sense of humor, and art from the beloved creator of Saturday Morning Breakfast Cereal, the Weinersmiths investigate perhaps the biggest questions humanity will ever ask itself—whether and how to become multiplanetary.
