Zubrin's Mars advocacy and the Mars Society

In the fourth and final episode of Understood: The Making of Musk, host Jacob Silverman launches into Musk’s ultimate quest, his desire to colonize Mars, and how he went from wanting to save earth to wanting to escape it. 

You’ll hear the origin story of SpaceX. And hear from an astrophysicist who says Musk’s plan is completely delusional.
