Mission overview

After changing a few experiments on board the Mir station, everyday research began for the sixth permanent crew. These included earth exploration, medicine, materials science, biology, astronomy, and space technology. So one began with the commercial production of single crystals of highest purity for an American electronics company. The production of proteins was also profitable (approx. 25 million rubles).

When the old crew found a defect in the Soyuz TM-9's thermal insulation on their return, repairs became necessary. To do this, the cosmonauts got out on July 17th for exactly 7 hours. After a successful repair (three insulation sheets were bent open by 60 ° - 90 °) it was not possible to close the access hatch on the Kwant 2 module . So the re-entry had to be done through a lock in the base block. Solovyov and Balandin made an unsuccessful attempt on July 26 to repair the hatch (exit for 3 hours and 31 minutes). The cosmonauts had previously controlled the docking of the new crystal materials science module. It was then transferred to the coupling point opposite that of the Kwant-2 module. The Progress M3 and 42 transport spacecraft delivered supplies . In August the station was handed over to the successor crew.
