After replacing some of the experiments aboard the Mir station the daily research for the sixth crew began. These included earth science, medicine, materials science, biology, astronomy and space technology. So they started the commercial production of high-purity single crystals for an American electronics company. Also profitable (about 25 million rubles ) was the production of proteins.
When the old crew of a defect in the insulation temperature of Soyuz TM -9 found on their return, repair work was necessary. For this purpose, the cosmonauts stepped out for exactly seven hours on July 17. After a successful repair ( three insulation panels were around 60 ° - 90 ° bent ) it was not possible to close the hatch on Kvant 2 module. Thus, the re-entry via a lock in the basic block had to be done. Solovyov and Balandin took on July 26, an unsuccessful attempt to repair the hatch ( exit for 3 hours and 31 minutes). Previously, the cosmonauts had controlled the docking of the new materials science module crystal. It was subsequently converted to the coupling place, which lies opposite to that of the 2- module Kvant. Supplies was delivered to the transport spacecraft Progress M 3 and 42. In August, the station was handed over to the successor occupation.
