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? Bestselling authors Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of original research, and interviews with leading space scientists, engineers and legal experts, they aren't so sure it's a good idea. Space tech and space business are progressing fast, but we lack the deep 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 a nightmare, both for settlers and the people they leave behind.

With deep expertise, a winning sense of humour 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.
Quick read with some humor sprinkled in here and there. Good structure makes it easy to skip sections that one finds boring. Overall it gives a good perspective on the various challenges of space settlements.
Accessible and intricately researched, with scattered humor to keep the reader's interest.
Getting to space is the easy part. Staying there is going to be a lot more complicated than anyone wants to believe. There are plenty of established tropes in science-fiction and among serious space enthusiasts, but a lot of them have major gaps in them when you start pressing for details. What happens to a fetus in microgravity? Can you scrape together enough soil nutrients to supply agriculture for a whole Mars city, or do you need to constantly import fertilizer from Earth? How do you make sure you have enough medical supplies on-hand?
The authors wanted to write about what we know about space settlement. But it turns out it's a really good primer for what we don't know and need to research before we can get serious.

It's also an interesting companion to Under Alien Skies, which takes the approach of "assuming we're able to work out the details, this is what it would be like there." And, well, we have a lot more details to work out.
If you've looked askance at Elon Musk's claim/plan to settle Mars this century, this book will validate your priors in a most entertaining way. The first 3 parts cover the physical & mental aspects of space settlement. As someone who works on satellites, none of this is surprising to me. At least a couple times a week, someone in the office will exclaim "space is hard!" as we try to solve a problem. Additionally, the book spends 2 parts of the legal and geopolitical environment of settling space. The authors' position is that space settlement nerds don't really spend enough time thinking through the ramifications. In particular, while there are better frameworks for space settlement than what we have, there's not a clean path to get there and space settlement nerds aren't really moving society in a real way to get there. There's an extended discussion of an attempt to …

In particular, while there are better frameworks for space settlement than what we have, there's not a clean path to get there and space settlement nerds aren't really moving society in a real way to get there. There's an extended discussion of an attempt to establish a new state in space by dint of a small cubesat launched by a space society. (As a side note, I'm quite surprised that the book doesn't go into the attempts to create micro-states such as Sealand. Those would be a lot easier to attain statehood with that space environments, and yet none of those has even come close to succeeding.)
What really makes the book though is that the authors are both funny and pay attention to the weird facts of space. Steve Bannon once ran Biosphere 2! The humor won't be a surprise to regular readers of Zach Weinersmith's web strip, Saturday Morning Breakfast Cereal.
A City on Mars (EBook, 2023, Penguin Press)
5 stars
I really enjoyed the breadth (and depth) of the analysis the Weinersmith's make in this book. The science-y bits were great, but the law related pieces were the most interesting in my opinion.
I think their point about how space exploration geeks just completely skip over law was really insightful. The fact that we already have international law that most likely applies to the moon, and the different reasons why powerful countries agree to international law or not, was interesting.
After reading this book, I came away significantly less enthusiastic about a settlement on Mars (or the Moon) however I still, like the authors, think it is a good use of time and money if done the right way.
