The Reality of Building Cities in Space: Challenges and Envisioned Life on Mars and the Moon

A new book titled "A City on Mars" by Kelly and Zach Weinersmith explores the challenges and uncertainties surrounding the idea of building cities in space. The authors found that there is little research on the long-term health effects of living on the moon or Mars, particularly in relation to human reproduction and development. They also highlight the legal complexities and potential conflicts over property rights in space. The Weinersmiths argue that more research and international negotiations are needed before humanity can realistically establish sustainable space settlements.
