Yi So-yeon (born June 2, 1978) is a South Korean scientist and Ph.D. graduate of KAIST (Korea Advanced Institute of Science and Technology). On April 8, 2008, she became the first Korean^[1] and the second Asian woman (defined as a female resident of a country in Asia at the time of her spaceflight)^[2] to fly in space, after Chiaki Mukai.

[edit] Biography

Yi So-yeon was born to father Yi Gil-soo and mother Jeong Geum-soon and raised in Gwangju, South Korea.^[3]

Yi studied at Gwangju Science High School. She earned bachelor’s and master’s degrees with a focus on mechanics at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon. Her doctorate in biotech systems was conferred on 29 February 2008 in a ceremony at KAIST although she was unable to be present due to her training commitments in Russia.

[edit] Korean Astronaut Program

Main article: Korean Astronaut Program

Yi So-yeon and Ko San participate in a space station hardware training session in the Space Vehicle Mockup Facility at the Johnson Space Center by Crew Systems instructor Glenn Johnson.

Yi was one of the two finalists chosen on 25 December 2006 through the Korean Astronaut Program. On 5 September 2007, the Korean Ministry of Science and Technology chose Ko San, over Yi So-yeon, following performance and other tests during their training in Russia.^[4][5]

On 7 March 2008, she was selected to train with the primary crew, and on 10 March the Ministry of Education, Science and Technology announced that Yi would replace Ko. This was after the Russian Federal Space Agency asked for a replacement because Ko violated regulations several times at a Russian training center by removing sensitive reading materials and mailing one back to Korea.^[6][7][8][9] On 8 April 2008, Yi was launched into space on board Soyuz TMA-12, with two Russian cosmonauts. South Korea is reported to have paid Russia $20 Million for Yi's space flight. ^[10]She makes South Korea the third country, after the United Kingdom and Iran, to have a woman as its first space traveler.

[edit] Terminology

Flying as a guest of the Russian government through a commercial agreement with South Korea, Yi's role aboard Soyuz and the ISS is referred to as a spaceflight participant (Russian: uchastnik kosmicheskovo poleta) in Russian Federal Space Agency and NASA documents and press briefings.^[11]

[edit] Mission

Yi So-yeon

During her mission, Yi So-yeon carried out 18 science experiments for KARI and conducted interviews and discussions with media. In particular, she took with her 1,000 fruit flies in a special air-conditioned container box (Konkuk University experiment). She monitored the way the changes in gravity and other environmental conditions alter the behaviour of the flies, or their genome. Other experiments involved the growth of plants in space, the study of the behaviour of her heart, and the effects of gravity change on the pressure in her eye and shape of her face. With a specially designed three-dimensional Samsung camera, Yi took six shots of her face every day to see how it swells in the different gravity. She also observed the Earth, and in particular the movement of dust storms from China to Korea.^[12] She will also measure the noise levels on board the ISS.^[13]

South Korean scientists created a special low-calorie and vitamin-rich version of kimchi for Yi.^[14]

[edit] Return flight

At the end of the mission, Yi returned to Earth along with ISS crew members Peggy Whitson and Yuri Malenchenko aboard Soyuz TMA-11. The craft followed a ballistic re-entry, which typically subjects the crew to extreme force. The re-entry into Earth's atmosphere was a steeper than usual descent, thus subjecting the crew to severe gravitational forces at up to 10 times the amount experienced on Earth. As a result of the re-entry, the TMA-11 craft used in the return flight landed 260 miles (418 km) off-course from its target in Kazakhstan. ^[15] All three survived, although requiring observation by medical personnel.^[16]

Yi was hospitalized after her return to Korea due to severe back pains caused by the rough return voyage^[17].

[edit] Post-flight

After her flight, Yi works as a researcher at KARI as well as acting as Korea's space ambassador, together with Ko San. She will also receive income from future TV commercials.^[18]
