Jun'ichirō Kawaguchi

There's a certain kind of quiet hero who never trends on social media but absolutely should, and Jun'ichiro Kawaguchi is exactly that guy. He grew up in Hirosaki, deep in Aomori snow country, went to the University of Tokyo, and ended up at JAXA steering one of the most audacious space missions ever attempted — sending the Hayabusa probe to asteroid Itokawa, over 300 million kilometers away, collecting a sample, and coaxing the thing back home after it went nearly silent and everyone assumed it was lost. The fact that Hayabusa limped back to Earth in 2010 after years of malfunctions, against what seemed like impossible odds, is one of those real-life stories that makes scripted drama feel lazy. Kawaguchi didn't give up on his spacecraft, and honestly that stubbornness from a kid out of northern Japan saving a probe that the universe kept trying to kill is just genuinely moving to me.

Jun'ichirō Kawaguchi is a Japanese scientist born on September 24, 1955, in Hirosaki, Aomori Prefecture, Japan. He studied at the University of Tokyo. He is recognized as a scientist with roots in Aomori Prefecture.
