He helped to build the International Space Station. He flew three times in a space shuttle and once in a Crew Dragon. He performed ten spacewalks. Before becoming an astronaut, he was underwater.

And now he is looking forward to watching the return to the Moon and on the Lunar surface — the Artemis program. He says he is stubborn. And he likes to solve problems. NASA astronaut Stephen Bowen.
