Outer space is back in style. For the first time in decades, NASA is sending astronauts back to the moon. Millionaires are exiting the atmosphere on a regular basis. And Elon Musk says humans may land on Mars to set up settlements by 2030. But would mastering space be worth it?

In their new book, “A City on Mars,” co-authors (and spouses) Dr. Kelly and Zach Weinersmith argue that it’s probably not. From biology to engineering to international law, they charmingly survey the many charms and dangers that space inevitably entails, with pictures to boot. For this week’s Chatter episode, Scott R. Anderson spoke with Kelly and Zach about their book, what role they think space exploration and settlement should play in humanity’s future, and why space may not be all it’s cracked up to be anytime soon.

Among the works mentioned in this episode:

• The book “Soonish,” also by Kelly and Zach.
• The book “Dark Skies: Space Expansionism, Planetary Geopolitics, and the Ends of Humanity” by Daniel Deudney.
• The book “The Creation of States in International Law” by James Crawford.
• The television series “The Expanse.”
• The 1970s film “Libra.”
• The television series “For All Mankind.”
