We're Not Going to Mars Without the Moon First

Few people can say they’ve lived in space but Sandy Magnus has.

Listen on

In this episode of Deep, Ben Kaplan talks with the former NASA astronaut who spent four and a half months aboard the International Space Station, logged three shuttle missions, and later became Chief Engineer for Advanced Capabilities at the U.S. Department of Defense.

Magnus shares what it’s like to move to space rather than just visit, how living off-Earth changes your view of our fragile planet, and why microgravity may hold the key to new markets in biotech, manufacturing, and resource development.

She also breaks down the realities of commercial spaceflight from the economics of lunar mining and private space stations to the tension between safety and profit as companies like SpaceX, Boeing, and Blue Origin push the frontier forward.

If you want to understand where government, defense, and commercial space really intersect and what it takes to turn exploration into industry this episode goes beyond the countdown.
