Crew Notes


Yi So-yeon flew 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.[6] Ko San was originally scheduled to fly, with Yi as his backup. On 10 March 2008, it was announced that Ko breached regulations surrounding removal of books from the training centre in Russia,[7] and therefore would not be allowed to fly.[4]

Soyuz TMA-12 approaches the International Space Station for docking on 10 April 2008.

Richard Garriott flew as a private astronaut through a program run by Space Adventures. He is also referred to as a Spaceflight Participant in English-language RKA and NASA documents.

Soyuz TMA-12 saw the joined landing of the world's first two second-generation space travellers, Sergey Volkov and Richard Garriott. Volkov's father, Aleksandr Volkov, flew to space three times and visited the Salyut 7 and Mir space stations. Garriott's father, Owen Garriott, flew to space twice and visited the Skylab space station.
