Official NASA Biography - 1994
In February 1989, he was enrolled in a cosmonaut detachment as a candidate test cosmonaut. In the period from September 1989 to January 1991, he underwent the complete course of general space training and qualified as a test cosmonaut.
From February 1991 to March 1992, he trained for a flight on the Soyuz-TM transport vehicle and the Mir Station as a member of a group.
From March until July 1992, he underwent flight training to be the flight engineer of a back-up Russian-French crew comprised of G.M. Manakov, A.F. Poleshchuk, and J.P.Haigneré, of France.
He underwent a complete course of training to be the flight engineer for the Soyuz-TM transport vehicle and Mir Station for the 13th primary expedition and, in the period from January 24 to March 22, 1993, accomplished a 179-day space flight with G.M. Manakov.
During the flight, two EVAs were performed, lasting a total of 9 hours and 58 minutes. Testing of the androgynous peripheral docking subassembly of the "Kristall" module was performed.
At present, he is undergoing flight training to be the flight engineer of the stand-by Russian crew for the Mir-18 expedition as part of the Mir-Shuttle program.
Soyuz TM-13 and TM-14 crews were reshuffled extensively due to commercial seat bookings by Austria and Germany and the necessity of flying a Kazakh-born cosmonaut as part of the Baikonur rental agreement. This was the original crew assignment. The Kazakh researchers were moved to the earlier Soyuz TM-13 flight.
Mir Expedition EO-12. Russian astronauts Solovyov and Avdeev and French astronaut Tognini were inserted into an initial 190 x 200 km orbit inclined 51.6 deg. Later on July 27 they maneuvered to a 223 x 343 km orbit, and on July 28 docked with Mir in its 405 x 410 km orbit. Aleksandr Solovyov and Sergey Avdeev undocked from the Mir complex aboard Soyuz TM-15 on February 1 and landed the same day in Kazakhstan after six months in space at 03:58 GMT. Soyuz TM-15's flight was an in-orbit record for a Soyuz spaceship - 188 days 21 h 39 m.
Manned two crew. Mir Expedition EO-13. Transported to the Mir manned orbital station a crew of the thirteenth main expedition comprising the cosmonauts G M Manakov and A F Poleschuk.The Soyuz carried the APAS androgynous docking system instead of the usual probe system. Soyuz TM-16 landed at 06:42 GMT on July 22.
