As the head of science at NASA, Thomas Zurbuchen managed an $8.6 billion dollar budget. A typical Monday, for him, might have involved hitting an asteroid with a space craft or trying to launch a rocket.

In this episode, he shares what he learned about leading extremely technical, complex, and expensive projects with a high risk of failure.
