  • TWiS 201: Born to Explore - With Jay Gallentine
    Mar 13 2026

    When most people think about deep space exploration, management acumen is generally not the first thing they settle on—but without it, no robotic mission would ever succeed. This week we are joined by Jay Gallentine, author of multiple books on the robotic exploration of space. Each of these tomes is a somewhat of a masterpiece; a deep dive into a topic that few explore in such detail. His newest book, "Born to Explore," started off as a book about robots exploring Mars, but his interviews with former JPL manager John Casani was so compelling that he transformed it into a biography. John Casani is a legend at JPL and NASA, and his story reads like a combination of a spaceflight adventure, personal memoir, and a pirate's tale. You'll love the book, and you'll love hearing about it from Jay. Join us!

  • TWiS 199: The Obsolete Astronaut? - And a New Report on Crewed Mars Missions
    Feb 27 2026

    In this age of rapidly advancing AI and robotic technology, do we still need to send humans into space? The argument has long been that people can do things better and faster off-Earth, but the changing face of robotic tech has some feeling otherwise. This week's guest is a returning friend of the show, Dr. Pascal Lee, who has thoughts on how and when robots may perform better--and more safely--than humans in space, and then, of course, Tariq and I worry about how our mechanical masters might take our place in the cosmos. Pascal also reports on his recent experience with the National Academies' report on the human exploration of Mars. Join us!
