Space exploration is as much a story of leadership and teamwork as it is a story of exploration and discovery. Leadership Moments from NASA delves into the organizational culture, leadership styles, and insights of NASA senior executives spanning five decades of human spaceflight, to share the lessons they learned from critical moments where they took on seemingly insurmountable challenges.

Dr Dave has led the sort of life that most people only dream of. He has set records for spacewalking. He has lived undersea for weeks at a time. He has saved lives as an emergency doctor, launched into the stratosphere twice and performed surgery in zero gravity. But if you ask him how he became so accomplished, he’ll say, 'I’m just a curious kid from Saskatchewan.' Curious indeed.

Is the human body built for Mars? NASA's studies on the International Space Station show we need to fix a few things before sending people to the Red Planet. Astronauts go into space with good vision and come back needing eyeglasses. Cognition and DNA expression could be affected for years. And then there's the discomfort of living in a tight space with crewmates, depression, and separation from the people you love.

In Defying Limits, Dave Williams shares the events that have defined his life, showing us that whether we’re gravity-defying astronauts or earthbound terrestrials, we can all live infinite, fulfilled lives by relishing the value and importance of each moment. The greatest fear that we all face is not the fear of dying but the fear of never having lived. Each of us is greater than we believe. Together, we can exceed our limits to soar farther and higher than we ever imagined.
