Any reader enthusiastic about space settlement will find much to appreciate in this book . . . The Weinersmiths write with a confident belief that humanity will one day travel off-planet. Science 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 Twitterbeckons, 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.
