“Helpfully pulls back the curtain on some of the lesser-discussed challenges to humanity’s off-Earth pursuits . . . Any reader enthusiastic about space settlement will find much to appreciate in this book . . . [The Weinersmiths] write with a confident belief that humanity will one day travel off-planet.” –Science
From the bestselling authors of Soonish, a brilliant and hilarious off-world investigation into space settlement
Earth is not well. The promise of starting life anew somewhere far, far away—no climate change, no war, no Twitter—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. Space technologies and space business are progressing fast, but we lack the knowledge needed to have space kids, build space farms, and create space nations in a way that doesn’t spark conflict back home. 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.
Get in, we’re going to Mars.

“Science writing is rarely as readable (or deflating) as A City on Mars, an informed, irreverent study of how little we actually know of the practical considerations of space colonization, from sex and legal cannibalism to issues of settlement.” —Chicago Tribune, 75 Top Picks for Fall
“Starting life anew somewhere far, far away sounds appealing. But that fantasy is so much further from realization than we think, argues this wife-and-husband-team persuasively.” —MIT Tech Review

Wong,Science “A must-read!”—Jonathan McDowell, Center for Astrophysics, via X
“Excellent . . . sets out persuasively and amusingly why you would have to be wildly optimistic or crushingly stupid to want to set up a space settlement any time soon.” —Stephen Bush, FT
“Wickedly irreverent . . . The cheeky tone is loads of fun, and Zach’s humorous illustrations of, for instance, contraptions proposed to facilitate zero-gravity sex, entertain . . . A boisterous takedown of techno-utopianism.” —Publishers Weekly (starred review)

“There is simply no more engrossing, entertaining, or thorough way to understand the intense challenge of humanity's off-Earth future than A City on Mars. I laughed the whole way through.” —Hank Green, New York Times bestselling author of An Absolutely Remarkable Thing and host of CrashCourse and SciShow
“Scientific, educational, and fun as hell.”—Andy Weir, New York Times bestselling author of The Martian and Project Hail Mary
“Listen up, humans. How to poop in space will be the least of our concerns. Herein are challenges most space-heads, including me, never even considered: not just technological, but legal, ethical, geopolitical. Despite the breadth and depth of research and some impressive near-wonk-level detail, this is a clear, lively, and hilarious read. Slam dunk, Weinersmiths!"—Mary Roach, New York Times bestselling author of Fuzz and Packing for Mars
“This might be the best book ever written about humans in space, or at least the funniest. I don't know of anything else quite like it: an extended, comical confrontation between the dreams of space colonies and the gross, dangerous, tedious realities. Read it before you go.” —Scott Aaronson, Schlumberger Chair of Computer Science and Director of Quantum Information Center, University of Texas at Austin
"Of the many books and extensive literature on Space mission architectures, technical and otherwise, this is the only one that is a must-read to understand the deep financial, physiological and technical constraints of one of the largest and most ambitious endeavors of our time: enabling humans to become a multi-planetary species.” —Professor Sinead O'Sullivan, member of the Advisory Council of the European Space Policy Institute
“A fun, and sobering, exploration of what it means to explore beyond our planetary home. Sure, the stars beckon and TV shows and movies make space travel seem like a blast, but before you invest in another billionaire’s crypto-powered Mars colonization dream, you might want to pick up this book and learn about the risks, astronomical costs and thorny ethical issues involved. The Weinersmiths take you on a journey to our unlikely future on other planets with impressive detail, eye-opening facts, and extremely funny cartoons.” —Jorge Cham, author of Oliver’s Great Big Universe and creator of PHD Comics
“Earth may not be perfect, but we evolved here. Everywhere else in the Universe will try heartily to kill you in nasty ways. The Weinersmiths logically and patiently lay out the case that if we want to live in space, there's a lot of ground work to do first. If you're a gung-ho Moon and Mars enthusiast, this book will show you why it's best to slow down the space race just a bit.”—Phil Plait, writer of the “Bad Astronomy Newsletter”
“A City on Mars is deeply researched, hilarious, and sobering. Zach and Kelly Weinersmith have given us a bracing to-do list for the new age of space. Highly, highly recommended.” —James S.A. Corey, author of The Expanse series
“A refreshing, clear-headed breath of life-support oxygen amidst all the tech-bro naivety and hype on space colonisation. Impeccably researched and argued, yet witty and very easy to read. Superb!” —Professor Lewis Dartnell, New York Times bestselling author of Being Human
