Then Bruce Betts, the chief scientist of The Planetary Society, and I will talk about the most significant challenges humanity might face when we build habitats in space. Kelly and Zach Weinersmith join us this week to discuss their new book, A City on Mars. I'm Sarah Al-Ahmed of The Planetary Society, with more of the human adventure across our Solar System and beyond. Can we settle space? It might be more complex than you think, this week on Planetary Radio.
