Launch from the Baikonur Cosmodrome; ISS Expedition 17. Landing 94 km NNE of Arkalyk

Yi Soyeon flew on board Soyuz TMA-12 as a guest of the Russian government through the Korean Astronaut Program after the Korean government paid the Russian government 25 million US dollars in agreement to support the first Korean astronaut in space. Her role aboard the Soyuz is referred to as a Spaceflight Participant in English-language Russian Federal Space Agency and NASA documents and press briefings. Ko San was originally scheduled to fly, with Yi Soyeon as his backup. On March 10, 2008, it was announced that Ko San breached regulations surrounding removal of books from the training center in Russia, and therefore would not be allowed to fly. Yi Soyeon spent eight days conducting scientific experiments aboard the International Space Station.

Yi Soyeon was the first space traveller from South Korea. Following a two day solo flight Soyuz TMA-12 docked to ISS on April 10, 2008. Sergei Volkov and Oleg Kononenko replaced Expedition 16 crew members Peggy Whitson and Yuri Malenchenko.


Yi Soyeon landed on April 19, 2008 at 08:29 UTC with Soyuz TMA-11 spacecraft.
