Premier vol habité (abbreviated PVH , French for “first manned flight”) was the name of a French - Soviet research project in the context of which a Frenchman flew into space for the first time .
preparation
The basis of this Franco-Soviet project was an offer from the Soviet head of state Brezhnev to the French President Giscard d'Estaing in April 1979 to bring a French spaceman on board a Soyuz spaceship to a Soviet space station .
The French space agency CNES finally selected two from 400 applicants who were prepared for this flight: Jean-Loup Chrétien and Patrick Baudry .
scientific programme
Nine scientific experiments were prepared for this space flight:
astronomy
- PIRAMIG: Highly sensitive camera for the visible and near infrared range for studying the mesosphere and stratosphere , but also space.
- PCN: (Photographie du Ciel Nocturne) (Photography of the night sky): Very weak light sources were photographed, including remote regions of space, interstellar dust clouds or the distribution of lightning in tropical thunderstorms.
Materials science
- DIFFUSION: In this experiment, a polycrystalline alloy was dissolved in its own liquid to study diffusions in the liquid state.
- IMMISCIBLE : Alloys were produced by solidifying metallic emulsions in weightlessness.
medicine
- DS1 : This experiment used the Doppler effect to measure the flow rate of blood in arteries. This was used to examine the effects of weightlessness on the blood circulation.
- ECHOGRAPHY : This experiment examined the speed of blood flow and the cross-section of the heart and blood vessels. Values before, during and after the space flight were compared. This was the first time that sonography was used in space.
Life science
- POSTURE : Experiment to study muscle activity and sensory perception in weightlessness
- CYTOS II : The Cytos program has already started on the Salyut 6 space station . Cytos II examined the behavior of bacteria on antibiotics in weightlessness.
- BIOBLOC III : This experiment investigated the extent to which heavy cosmic ions have an impact on living organisms or their genes.
Flight history
Chrétien took off in the Soyuz T-6 spacecraft together with commander Vladimir Dschanibekow and flight engineer Alexander Ivanchenkov on June 24, 1982. On the following day, they docked with the Salyut 7 space station , which was manned by the first long-term crew Anatoly Berezovoi and Valentin Lebedev at the time.
A team swap was not planned, and so Dschanibekow and Ivanchenkov returned with Chrétien on July 2 in their spaceship.
Importance of Mission
This flight was the first space cooperation between the Soviet Union and a Western European country. Previously, only cosmonauts from communist countries were guests on board Soviet space stations as part of the Interkosmos program.
