Space Business Podcast #129 - Kelly Weinersmith, Co-Author: A City On Mars
A City on Mars: Can we settle space, should we settle space, and have we really thought this through? – That is the title of a book published in late 2023 which then became an instant NY Times bestseller and went on to win a 2024 Hugo Award. My guest this week is Kelly Weinersmith, one of its two authors, together with her husband. The book is a critical, and humorously written, examination of the question of whether humanity should settle space. It touches on everything ranging from legal aspects all the way to having babies in Space. For me as a die-hard proponent of humanity settling in space, this was a fun and insightful conversation to have. I’m sure you’ll enjoy it, too!
