In 2021, the U.S. space agency NASA launched a spacecraft toward a pair of asteroids more than 11 million kilometers away. The target? The smaller of the two asteroids, just 170 meters wide. The success of the $300 million, seven-year project demanded careful coordination of scientists, engineers, and project managers across different national space agencies. It also required strong leadership from NASA's head of science, Thomas Zurbuchen. He shares his path to an executive role at NASA, his management philosophies, and how he oversees trailblazing space missions with high risk of failure.
