Commanding the Axiom Mission 1 in 2022, Michael López-Alegría led the first all-private team of commercial astronauts to the International Space Station. His career spans decades of flight, transitioning from a career as a United States Naval aviator and test pilot into a role as a central figure in the commercialization of low Earth orbit.
Naval Aviation and NASA Selection
Born in Madrid in 1958, López-Alegría moved to Mission Viejo, California, during his youth. He graduated from the United States Naval Academy in 1980 with a degree in systems engineering and later earned a Master of Science in Aeronautical Engineering from the Naval Postgraduate School in 1988. Before joining NASA, he served as a test pilot and instructor at Naval Air Station Whiting Field and the Naval Air Test Center in Maryland. His training included the United States Naval Test Pilot School and the Harvard Kennedy School's program for senior executives.
