Mike Massimino
Mike Massimino helps organizations build resilient, high-performing teams through lessons learned as a NASA astronaut. A leadership and teamwork keynote speaker, Mike is a Columbia University professor, bestselling author, and veteran of two space shuttle missions.


Mike Massimino, a former NASA astronaut, brings a firsthand perspective on teamwork, resilience, and innovation forged in one of the most demanding environments imaginable: outer space.
A veteran of two space shuttle missions and four spacewalks, Mike is a professor of mechanical engineering at Columbia University and the senior advisor for space programs at the Intrepid Sea, Air and Space Museum. He is also a New York Times bestselling author, writing Spaceman and Moonshot, and was the first person to Tweet from space.
Mike's experience training for the most complicated spacewalk ever attempted and repairing the Hubble Space Telescope, gives him a rare vantage point on how teams solve problems when the stakes and the pressure are both extremely high. He persisted through three rejections over seven years before becoming an astronaut, including overcoming a medical disqualification, a story that speaks directly to persistence and adaptability.
Audiences leave Mike's talks with practical lessons on building high-performing teams, staying resilient through repeated setbacks, and embracing new technology rather than resisting it. His stories translate the discipline of human spaceflight into strategies that apply directly to business and leadership.
Mike offers audiences a rare, credible voice on teamwork and perseverance, grounded in real missions.
Topics, sessions and talks
When Mike Massimino arrived at NASA, he found a culture that placed the success of the team and the mission above any individual astronaut's accomplishments. That culture built strong relationships, not just between astronauts but with NASA's leadership, forged through years of shared training and the experience of spaceflight itself. Those bonds carried Mike and his colleagues through astronaut training, tragedy, and the repair of the Hubble Space Telescope, a foundation he traces to the teamwork and leadership that shaped his career.
Mike Massimino's second spaceflight came near the end of the Space Shuttle Program, as NASA faced retiring a proven vehicle, relying solely on Russia's Soyuz for years, and opening the door to commercial companies entering spaceflight. Mike walks audiences through how an organization built around one way of operating adapts when that model ends without losing its mission, connecting that period at NASA to the uncertainty organizations face when a familiar system gives way to something new.
A childhood spent watching Neil Armstrong's first steps on the moon planted an idea in Mike Massimino's mind that took decades, three rejections, and one medical disqualification to become real. Mike overcame that disqualification by training his own eyes to see better, then went on to fly two space shuttle missions and complete four spacewalks. His story makes the case that persistence, not talent alone, is what turns a distant goal into an achieved one.
Mike Massimino's first spaceflight was aboard Space Shuttle Columbia. On its next mission, the shuttle and its crew, seven of Mike's friends, were lost during re-entry. Amid the grief, Mike and his colleagues faced an urgent question: what would happen to an unfinished space station and a Hubble Space Telescope still needing repair. Refusing to let that loss be in vain, the team rebuilt the program from the ground up, a resolve Mike connects to organizations recovering from their setbacks.
It's easy to lose sight of why the work matters, even for astronauts. Mike Massimino encourages audiences to hold onto the bigger picture behind their effort, not just its daily challenges. For Mike, that purpose was servicing the Hubble Space Telescope, one of the most productive scientific instruments ever built, whose repairs unlocked discoveries that reshaped how we see the universe. Connecting to that larger purpose, he argues, is what makes the hard parts of any job worth it.
