Episode notes

The chapter explores the exercise needs of astronauts in space, including the challenges of maintaining bone and muscle mass in microgravity and potential differences in exercise requirements on Mars. It also discusses the rationale behind colonizing Mars, weighing the benefits of using resources for Martian settlement against addressing Earth's issues like climate change.

Can we settle space, should we settle space, and have we really thought this through?

The allure of a fresh start on a new planet has captivated humans for a very long time, and now, public figures like Elon Musk are trying to make it a reality. But should we? Is it even possible? And how would life on Mars even look like?

These are the questions Zach and Kelly Weinersmith tackled with a deep expertise and winning sense of humor in their new book, A City on Mars, which has become an instant bestseller.

Zach is a cartoonist and writer best known for his webcomic Saturday Morning Breakfast Cereal (SMBC). Outside of SMBC, he has worked on a sketch comedy series, a podcast, and multiple other webcomics. Kelly, on the other hand, is a biologist, writer, and podcaster. She is a faculty member in the Department of BioSciences at Rice University and an alumni collaborator with the Parasite Ecology Group at the University of California, Santa Barbara.

Today, Zach is joining me on Into the Impossible to discuss whether and how to become multi-planetary.
