Trained for missions under both US and Russian programs
In April 1979, the Soviet Union offered France the opportunity to fly a cosmonaut on board a joint Soviet-French space flight, along the same lines as the agreement to fly non-Soviet cosmonauts from member countries of the Intercosmos program. The offer was accepted, and France began a cosmonaut selection program in September 1979. Chr�tien was one of two finalists named on June 12, 1980. He started training at the Yuri Gagarin Cosmonaut Training Center in September 1980. The following year he was named as the research-cosmonaut for the prime crew of the Soyuz T-6 mission.
Soyuz T-6 was launched on June 24, 1982, and Chr�tien, Dzhanibekov and Ivanchenkov linked up with Salyut 7 and joined the crew of Berezovoi and Lebedev already on board. They spent nearly seven days carrying out a program of joint Soviet-French experiments, including a series of French echography cardiovascular monitoring system experiments, before returning to Earth after a flight lasting 7 days, 21 hours, 50 minutes, 42 seconds.
Following the mission he was appointed Chief, CNES Astronaut Office.
Chr�tien was selected as the back-up payload specialist for STS-51G. During 1984-85, he participated in mission training at the Johnson Space Center.
Chr�tien made his second space flight as a research-cosmonaut on board Soyuz TM-7, which launched on November 26, 1988. Together with Volkov and Krikalev, he linked up with Mir 1 and joined the crew of Titov Manarov and Polyakov already on board. They spent 22 days carrying out a program of joint Soviet-French experiments, including a 5 hour 57 minute EVA by Volkov and Chr�tien during which the two men installed the French ERA experimental deployable structure and a panel of material samples. In making the EVA, he became the first non-American and non-Soviet cosmonaut to walk in space. In addition, he was the first non-Soviet cosmonaut to make a second space flight aboard a Soviet spacecraft. The mission lasted 24 days, 18 hours, 7 minutes.
During 1990-93, Chr�tien participated in Buran spacecraft pilot training at the Moscow Joukovski Institute. He has also flown the Tupolev 154 and MIG 25 aircraft, flying simulators equivalent to the Shuttle Training Aircraft (STA).
Chr�tien is fluent in English and Russian.
Manned three crew. Docked with Salyut 7. Transported to the Salyut-7 orbital station the Soviet-French international crew, comprising V A Dzhanibekov (USSR), A S Ivanchenkov (USSR) and Jean-Loup Chretien (France) to conduct scientific research and experiments. Recovered July 2, 1982 14:21 GMT.
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.
Deployed ERA (French experiment).
Atlantis was launched on a mission to the Russian Mir space station. The TI rendevous terminal initiation burn was carried out at 17:32 GMT on September 27, and Atlantis docked with the SO (Docking Module) on the Mir complex at 19:58 GMT. The crew exchange was completed on September 28, with David Wolf replacing Michael Foale on the Mir crew. On October 1 cosmonaut Titov and astronaut Parazynski conducted a spacewalk from the Shuttle payload bay while Atlantis was docked to Mir. They retrieved four MEEP (Mir Environmental Effects Payload ) exposure packages from Mir's SO module and installed the Spektr solar array cap. The MEEP experiments had been attached to the Docking Module by astronauts Linda Godwin and Rich Clifford during Shuttle mission STS-76 in March 1996. In addition to retrieving the MEEP, Parazynski and Titov were to continue an evaluation of the Simplified Aid For EVA Rescue (SAFER), a small jet-backpack designed for use as a type of life jacket during station assembly.
Atlantis undocked from Mir at 17:28 GMT on October 3 and conducted a flyaround focused on the damaged Spektr Module to determine the location of the puncture in its hull. The Mir crew pumped air into the Spektr Module using a pressure regulator valve, and the Shuttle crew observed evidence that, as expected, the leak seemed to be located at the base of the damaged solar panel. Final separation of Atlantis from Mir took place around 20:28 GMT. After two landing attempts were waved off on October 5 due to heavy cloud cover, the crew fired the engines to deorbit at 20:47 GMT on October 6 and landed at Kennedy Space Center at 21:55.
