NASA Official Biography
Tognini has 4000 flight hours on 80 types of aircraft (mainly fighter aircraft including MIG 25, TUPOLEV 154, LIGHTNING MK 3 and MK 5, METEOR, and F 104). He is fluent in English and Russian.
Tognini made his first space flight on board the Soyuz TM-15, TM-14 (July 27 to August 10, 1992). Together with Anatoly Solovyev and Sergei Avdeiev he linked up with Mir 1 (ANTARES mission) and joined the crew of Alexandre Viktorenko and Alexandre Kaleri already on board. They spent 14 days carrying out a program of joint Soviet-French experiments before returning to Earth.
He returned to France following the mission. During 1993-94, he attended a training cycle of the French Institute for High Studies of National Defense (IHEDN).
A veteran of two space flights, Tognini has logged a total of 19 days in space.
Mir Expedition EO-04. Carried Alexander Volkov, Sergei Krikalev, Jean-Loup Chretien to Mir; returned Volkov, Krikalev to Earth. Initial Orbit: 194 X 235 km. Thereafter maneuvered to rendezvous orbit 256 X 291 km before docking with Mir in 337 X 369 km at 17:16 GMT 28 November.
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.
Chandra was deployed from Columbia a little more than seven hours into the flight at 6:47 a.m. CDT. Thanks to a pair of burns by its inertial upper stage (IUS), the third of NASA's four great observatories is now on its way to an elliptical orbit that will support five years of observations into the X-ray mysteries of the universe.

The Space Shuttle Columbia blasted off late Thursday night (early Friday morning, Eastern time) to carry five astronauts to orbit for the long-awaited deployment of Chandra X-Ray Observatory, which will unveil previously invisible mysteries of the universe. Additional Details: here....
STS-93 was first rolled out to pad 39B on June 7 1999. The Chandra/IUS-27 vehicle was placed in the payload canister on June 19. The first launch attempt was on July 20, but controllers aborted the launch at T-6 seconds, just before main engine ignition, due to a data spike in hydrogen pressure data. This was determined to be due to a faulty sensor and a second attempt was on July 22. A lightning storm prevented launch during the 46 minute window, and the launch was again scrubbed. Finally the vehicle lifted off the pad on July 23, but five seconds after launch a short in an electrical bus brought down two of the three main engine controllers. Backup controllers took over, but a further failure on the backup controller bus would have resulted in engine shutdown and the first ever attempt at an RTLS (Return To Launch Site) abort. To further complicate matters engine 3 (SSME 2019) had a hydrogen leak throughout the ascent, causing the engine to run hot. Controllers sweated as temperatures neared redline. The hot engine's controller compensated as programmed by using additional liquid oxygen propellant. The final result was that the shuttle ran out of gas - main engine cut-off (MECO) was at 04:39 GMT, putting Columbia into a 78 km x 276 km x 28.5 degree transfer orbit. Columbia was 1,700 kg short of oxygen propellant and 5 meters/sec slower than planned. The OMS-2 engine burn at 05:12 GMT circularised the orbit 10 km lower than planned.
The orbiter payload bay contained only the Chandra spacecraft, the IUS, and the IUS tilt tableTthe following payloads were carried in the shuttle's cabin: STL-B (Space Tissue Loss), CCM (Cell culture module), SAREX-II (Shuttle Amateur Radio Experiment), EarthKam, PGIM (Plant Growth Investigations in Microgravity), CGBA (Commercial Generic Bioprocessing Apparatus), MEMS (Micro-electric Mechanical System), and BRIC (Biological Research in Canisters) and SWUIS (the Southwest Ultraviolet Imaging System, an 0.18-m UV telescope to be used for airglow and planetary observations); GOSAMR (the Gelation of Sols: Applied Microgravity Research experiment) and LFSAH, the Lightweight Flexible Solar Array Hinge. MSX and SIMPLEX experiments were also to be carried out.
Chandra/IUS-27 was deployed from Columbia at 11:47 GMT July 23. Flight duration was limited; this was the heaviest shuttle (122,534 kg) and heaviest payload (19,736 kg) to that date. Columbia landed at 03:20 GMT on July 28 on runway 33 at Kennedy Space Center. Post-flight inspection found the presence of holes in the cooling lines on the nozzle of SSME 2019 (engine 3) which caused a hydrogen leak. A loose repair pin in the engine broke free and caused the failure. The cause of the short was found to be chaffed wiring inside the shuttle. The entire fleet was grounded for inspection and replacement of wiring as necessary.
Commander Eileen Collins, Pilot Jeff Ashby and Mission Specialists Cady Coleman, Steve Hawley and Michel Tognini worked on experiments involving everything from astronomy to biomedicine to plant growth as the shuttle continued to orbit the Earth every 90 minutes in excellent shape.

Commander Eileen Collins, Pilot Jeff Ashby and Mission Specialists Cady Coleman, Steve Hawley and Michel Tognini conducted experiments ranging from astronomical observations with an ultraviolet telescope to cell culture studies. Investigations also included testing new materials which may one day be used to fabricate sturdier solar arrays. Additional Details: here....
Columbia's astronauts made final preparations Tuesday evening to come home after a successful five-day flight. Commander Eileen Collins, Pilot Jeff Ashby and Mission Specialists Cady Coleman, Steve Hawley and Michel Tognini were awakened at 2:31 p.m. CDT Tuesday to "A Little Traveling Music" by Barry Manilow, requested by Hawley's wife Eileen, and "The Air Force Song," played for Collins and Coleman.
