Library's review
Konklusionen er at det er voldsomt svært og måske endda umuligt at oprette en koloni af jordmennesker på Mars. Bogen er gennemtænkt og nydeligt illustreret med et gran eller to humor undervejs. Hvor stort skal et terrarium være for at der kan bo mennesker i det?

Description
"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"--… (more)

As
A large section of the book is also devoted to examining legal and ethical concerns regarding space settlement, and though I found myself skimming a fair bit of the detail that covered the former, the issues raised were interesting to consider. The analogy with company towns is a clever comparison, I look at the mess Musk’s ego has made of Twitter, and know I could never trust him to act in my (or society’s) best interests.
The Weinersmith’s interject some humour into their work, which enhances its readability and their enthusiasm for the topic comes across well. Zach’s illustrations are a lighthearted, if superfluous, addition. I do think readers will require at least a casual interest in the subject to stay engaged with the narrative. The length of the book works against it slightly, though I appreciate the authors’ thoroughness.
A City on Mars is a pretty pessimistic view of the viability of space colonisation, there are still many questions to be answered and I agree with the Weinersmith’s conclusion that just because we can, doesn’t mean we should. Life in space is no guarantee of utopia, in fact we’d just be taking all the same problems with us, and likely creating many more.
In particular, they focus on a lot of issues that advocates of space settlement tend to gloss over or ignore while they're busy thinking about rocket schedules and mineral abundances. Like, for instance, the fact that the longest anyone has ever been in space is about a year and a half and no one's ever lived in Moon gravity for more than a few days or Mars gravity at all. So we have zero data on what it would mean, physiologically, to spend a lifetime somewhere other than Earth, or whether we can reproduce there without problems. Indeed, there hasn't even been much in the way of good animal experiments on any of that yet. Then there are issues of psychology and government, because no matter what the most idealistic of space dreamers might want to believe, humans do inevitably take our own flawed humanity with us wherever we go. And what about legal barriers? Does current space law even permit this sort of thing? Do we need to have clearer and more useful international law on the subject first to prevent problems down the road? And is expanding into space going to usher in a new era of cosmic harmony, or is it likely to actually be a new source of conflict?
On top of which, the simple fact is that space is a terrible place. As is the moon, as is Mars. It is profoundly difficult to overestimate just how hard it will be to keep human beings alive there, never mind thriving, or how much of what we take absolutely for granted on Earth will have to be struggled for there. Antarctica is a garden spot by comparison.
None of which is probably anything space enthusiasts (of which I do count myself one, although never one who thought Elon Musk-style near-term Mars settlement was anything but a pipe dream) are likely to want to hear. But whether or not you're convinced by their arguments, they are very much worth listening to, and the authors are certainly right that not enough attention is paid to these topics.
I should say that, while this sounds like a massive downer, it is written in a pleasant, humorous style (even if it is sometimes a stretch to keep that up during long chapters about international law), and also that the authors don't think that cities on Mars don't sound awesome, or even that they're not a good long-term goal for humanity. Ultimately, their argument is for doing it when we're actually truly capable of doing it right... and that that is really not today.
