A city on Mars

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? 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.
