Soyuz T-10 is the mission designation for the flight of a Soviet Soyuz spacecraft to the Soviet space station Salyut 7, which started on February 8, 1984 . It was the fifth visit by a Soyuz spacecraft to this space station and the 71st flight in the Soviet Soyuz program.

Starting crew

Kisim and Solovyov had previously formed the reserve crew of the previous flight, the take-off of which was canceled (see Soyuz T-10-1 ). Atkow had previously not been called to a support or reserve team.

Mission overview

The spacecraft served the third long-term crew of Salyut 7 with the mission designation Salyut 7 EO-3 for the outward flight. The crew of three entered the dark Salyut station with flashlights. She reported a burnt metal smell in the docking unit. After the space station was restored to working order, an extensive work program began for the cosmonauts. It comprised experiments on earth exploration, ecology, biology, materials research and detailed investigations in the field of medicine by the doctor Atkow.

In the course of the Gyunesch experiment, areas in six different climatic zones from seven different heights were examined. The space station represented one of these levels. Biological experiments concerned plant growth and the development of microorganisms in weightlessness. Of particular medical interest were the adaptation of the cosmonauts to weightlessness, the change in subjective sensations over a long period of time, the blood supply to the eye, changes in the position of the heart in the chest, physical performance and the testing of special training methods. In addition, studies of carbohydrate and salt exchange were carried out, pressure cuffs and medication against space traveler's disease were tested, the bioelectrical activity of the heart was measured and the volume of blood circulation was determined. For the first time, certain yoga exercises to improve performance were also performed. Psychological tests and the testing of new medical devices, such as an improved electrocardiograph, rounded off the medical examination program. The production of biochemical preparations began on board the station. With the help of various melting furnaces, new types of semiconductors were tested and ideal single crystals were grown (corundum). Furthermore, stress tests were carried out on various materials in the open space, which will later be used in the construction elements of the station.

Since the Soyuz spaceships could only stay in space for a limited time, but the planned mission duration was longer, a spaceship exchange had to be carried out. Commandant Malyshev's crew brought a new spacecraft to the station with the Soyuz T-11 and returned to Earth on April 11, 1984 with the Soyuz T-10.
