Koichi Wakata
Koichi Wakata (born August 1, 1963, Saitama, Japan) is a Japanese astronaut who accumulated a number of records during his career. Among them, he spent the longest time in space of anyone who was not an American astronaut or a Russian cosmonaut, staying in orbit for over 504 days. He was the first Japanese astronaut to go on five spaceflights. In addition, in 2014 Wakata became the first Japanese astronaut to command the International Space Station (ISS).
When Wakata was a young boy he dreamed of becoming an astronaut. However, he did not think it was possible, because at that time Japan did not have any astronauts. He instead turned his attention to building and flying airplanes. Wakata attended Kyushu University in Fukuoka, on the island of Kyushu. He received a bachelor’s degree in aeronautical engineering in 1987 and a master’s degree in applied mechanics in 1989. Years later, in 2004, he earned a doctorate in aerospace engineering.
In 1989 Wakata began to work at Japan Airlines as an aircraft structural engineer. Three years later the National Space Development Agency of Japan (now the Japan Aerospace Exploration Agency, or JAXA) chose him to begin astronaut training. The organization sent him to train with the National Aeronautics and Space Administration (NASA) at the Johnson Space Center in Houston, Texas. There he explored such subjects as shuttle and ISS robotics, shuttle payloads, and ISS operations.
In 1996 Wakata went on his first flight into space in the space shuttle Endeavour on the STS-72 mission. He operated the shuttle’s robotic arm to retrieve a Japanese satellite, the Space Flyer Unit, that had been launched several months earlier and to release and retrieve an American satellite, the Office of Aeronautics and Space Technology-Flyer, which flew on its own for two days.
In 2000 Wakata journeyed to the ISS on the shuttle Discovery on the STS-92 mission, which was the 100th space shuttle flight. Once again he used the robotic arm, this time to move and install portions of the space station. In 2006 Wakata commanded a small team at the National Oceanic and Atmospheric Administration’s undersea habitat off the coast of Florida. During the weeklong stay the crew attempted missions on the ocean floor. The undersea environment simulates the conditions in space.
In 2009 Wakata undertook his first long-duration mission at the ISS, launching for a second time aboard Discovery on STS-119. He stayed for about five months, becoming the first Japanese astronaut to live at the ISS for an extended period of time. While there, he conducted experiments and attended to station installations using the robotic arms. He returned to Earth aboard Endeavour on STS-127.
Wakata began a six-month stay at the ISS at the end of 2013, launching aboard a Russian spacecraft on the Soyuz TMA-11M mission. For two of those months, in 2014, he served as commander of the space station. During that time he was responsible for the safety of the astronauts as well as the routine running of the station.
In 2022 he went to the ISS on his third long-duration mission, Crew-5, aboard SpaceX’s Dragon spacecraft Endurance. He became one of the few people to have flown aboard three different types of spacecraft: the space shuttle, Soyuz, and Dragon. He also made two spacewalks with American astronaut Nicole Aunapu Mann.
