Before the spacecraft could undock, however, it was necessary that the ladders and tools used on the inspection be removed. In addition, Mission Control wanted the cosmonauts to examine the Kvant 2 hatch, which had been damaged when it was unlatched too early. With the airlock out of action, the cosmonauts again depressurised the module's instrument compartment and emerged into open space. The TV images of the hatch showed that one of the hinges was obviously deformed, so while the engineers thought that over the cosmonauts moved to the docked TM-9 and began dismantling the worksite. At the end of the EVA they were instructed to try to force the hatch shut, which they eventually managed, as they found difficulty in gaining enough leverage. The airlock chamber and instrument compartment were repressurised and the inner airlock hatch closed, after which the cosmonauts removed their space-suits. After 24 hours the airlock showed no sign of leakage, so they were given permission to leave the inner hatch open. On 4 August, as the cosmonauts handed over control of Mir to the new resident crew, Vladimir Shatalov, head of the Cosmonaut Training Centre, was quoted on Radio Moscow as saying that a single EVA would suffice to repair the hatch. However, some felt that this was over-optimistic and intended to placate those critics of Mir who claimed that too much time was required for maintenance to keep the station running, decreasing the amount of scientific work that could be done. Second EVA for both cosmonauts; Balandin's last, giving a career total of 10 hr 47 min. 1 Link to comment Share on other sites More sharing options...
