To Dan Tani, becoming an astronaut seemed unimaginable. And yet, for 16 years, Tani lived his dream as a NASA astronaut, going on two space expeditions. In this episode, Tani reflects on his pride in the U.S., his love for planet Earth, and his passion for sharing his experiences with others. Among all of his identities, Tani is proud to be a good “citizen of the planet.” Voices of Exchange is a podcast from the U.S. Department of State, brought to you by the Office of Alumni Affairs at State’s Bureau of Educational and Cultural Affairs (ECA), featuring stories from the millions-strong exchange program alumni network.
