Japanese astronaut who flew on the International Space Station for 141 days, conducting scientific experiments and spacewalks. Known for being the first Japanese astronaut to spend over 100 days in space.
Kimiya Yui is a trailblazing Japanese astronaut from the Japan Aerospace Exploration Agency (JAXA), renowned for being the first astronaut with a military background. His extraordinary journey has taken him from the skies as a fighter pilot to the depths of space, making him an inspiration to many.
Born on January 30, 1970, in Kawakami, Nagano, Japan, Yui's fascination with the sky led him to enroll in the National Defense Academy of Japan in 1992. He graduated and joined the Japan Air Self-Defense Force, where he piloted an F-15 Eagle fighter and worked in the Air Staff Office's Defense Planning Division.
In 2009, Yui was selected as an astronaut candidate by JAXA, marking a significant milestone in his career. He underwent rigorous training, becoming certified as an ISS astronaut in July 2011. This achievement was remarkable, as Japanese government policy historically separated scientific fields from military works, making Yui the first astronaut with a military background.
In June 2012, Yui participated in the NEEMO 16 undersea exploration mission, aboard the Aquarius underwater laboratory. He spent over 24 hours underwater, officially becoming an aquanaut on June 12. This unique experience prepared him for the challenges of space exploration.
In November 2016, Yui assumed the role of Chief of the JAXA Astronaut Corps, overseeing the training and development of future astronauts. His leadership has been instrumental in advancing Japan's space program.
In 2013, Yui was assigned as backup Flight Engineer for Italian astronaut Samantha Cristoforetti on ISS Expedition 42/43. He later became the prime crew Flight Engineer for ISS Expedition 44/45, launched on July 22, 2015, alongside cosmonaut Oleg Kononenko and astronaut Kjell Lindgren.
Kimiya Yui's remarkable journey serves as a testament to his dedication, perseverance, and passion for space exploration. As a pioneer in Japan's space program, he continues to inspire future generations of astronauts, scientists, and engineers.
Yui's story is a shining example of the power of human curiosity, pushing the boundaries of what is possible, and exploring the unknown.
