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? 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.

What will the world of tomorrow be like? How does progress happen? And why don't we have a lunar colony already? In this witty and entertaining book, Kelly and Zach Weinersmith give us a snapshot of the transformative technologies that are coming next - from robot swarms to nuclear fusion powered-toasters - and explain how they will change our world in astonishing ways. By weaving together their own research, interviews with pioneering scientists and Zach's trademark comics, the Weinersmiths investigate why these innovations are needed, how they would work, and what is standing in their way.
