 He was selected as part of the RKKE-15 Cosmonaut group in 2003.
Soyuz TM-29 was a Russian manned spacecraft launched from the Baikonur Cosmodrome aboard a Soyuz 11A511U rocket.
 It docked with Mir on February 22 at 05:36 GMT with Cosmonauts Viktor Afanasyev of Russia, Jean-Pierre Haigneré of France, and Ivan Bella of Slovakia aboard.
 Since two crew seats had been sold (to Slovakia and France), Afanasyev was the only Russian cosmonaut aboard.
 This meant that Russian engineer Avdeyev already aboard Mir would have to accept a double-length assignment.
