"A wonderful example of what it means to really think a difficult project through, a skill that many of us should acquire . . . The Weinersmiths are self-confessed space geeks who tread a fine line between the sort of constructive critique that would still qualify them as bona fide members of the space-settlement movement and a style of gentle ridicule that might get them rejected as traitors to the cause. A City on Mars is, foremost, a case study in the application of common sense." --Shlomo Angel, Wall Street Journal

"An exceptional new piece of popular science . . . Forceful, engaging and funny... an essential reality check for anyone who has ever looked for home in the night sky . . . hilarious.

"Laugh-out-loud-funny." --Scientific American

"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

"The Weinersmiths artfully encourage readers to entertain the thought of living on Mars while skillfully highlighting the absurdity of such a prospect through compelling data and delving into serious questions all through a lighthearted lens . . . [this] tongue-in-cheek narrative will captivate even the skeptics, directing their gaze upward at night." --Debbra Palmer, The New York Journal of Books

"Helpfully pulls back the curtain . . . painstaking research, clear-eyed objectivity, and good-natured humor . . . Any reader enthusiastic about space settlement will find much to appreciate in this book . . . most importantly, they write with a confident belief that humanity will one day travel off-planet." --Gifford J. Wong, Science

"Entertaining and informative romp through what's stopping us from moving off-planet . . . Well researched and argued, it's also a very fun read." --Jennifer Rothschild, Arlington Magazine

"Full of some of the choice-iest bits of awkward human space exploration histories and theories . . . could have been the research notes for an Ursula K. Le Guin, or a James S. A. Corey story, except that it's filled with jokes, palette cleansing anecdotes and charming cartoon illustrations . . . a popular science book that reads like a conversation with a friend . . . you can't get away from this book without thinking about how precious life on Earth is." --Mark Popinchalk, Astrobites

"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

"Inventive, funny, and informative . . . Filled with fun illustrations that bring the writing to life, this accessible and thought-provoking book explores what it will really take to build a society on another planet." --American Scientist

"[A] romp through the many rooms of space folly... amusingly literal and impeccably scientific"--Stuart Jeffries, The Guardian, Book of the Day (UK)

"A very funny book, underpinned by deadly serious questions about the future of humanity." --Ben Spencer, 19 Best Science and Environment Books of 2023, The Times (UK)

"Informative and entertaining"--Andrew Crumey, Literary Review (UK)

"Manages to be at the same time informative, sceptical and hilarious"--Engineering and Technology, Books of the Year

"Immersive and entertaining . . . the Weinersmiths' passion and enthusiasm shine through every page of this absorbing, lively exploration." --Booklist (starred review)

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

"A must-read!" --Jonathan McDowell, Center for Astrophysics, via X

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
