Document 2: Patrick Baudry: Patrick Pierre Roger Baudry (born March 6, 1946 in Cameroon), is a retired Lieutenant Colonel in the French Air Force and a former CNES astronaut.

Document 3: Soyuz TM-29: 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. After the February 27 departure of EO-26 crew commander Padalka and cosmonaut Bella aboard Soyuz TM-28, the new EO-27 Mir crew consisted of Afanasyev as Commander, Avdeyev as Engineer and French cosmonaut Haigneré.

Document 14: Soyuz TM-3: Soyuz TM-3 was the third manned spacecraft to visit the Soviet space station Mir, following Soyuz-T15 and Soyuz-TM2. It was launched in July 1987, during the long duration expedition Mir EO-2, and acted as a lifeboat for the second segment of that expedition. There were three people aboard the spacecraft at launch, including the two man crew of the week-long mission Mir EP-1, consisting of Soviet cosmonaut Alexander Viktorenko and Syrian Muhammed Faris. Faris was the first Syrian to travel to space, and as of November 2010, the only one. The third cosmonaut launched was Aleksandr Aleksandrov, who would replace one of the long duration crew members Aleksandr Laveykin of Mir EO-2.
