Mir Mission Designation: EO-6

Thermal protection sheets on the capsule came loose. On 17 July 1990, Solovyov and Belandin went out to repair the insulation. With the job mostly complete, and running low on oxygen, they reentered Mir through the Kvant-2 module. The airlock hatch would not close properly. Fortunatedly, the design of Kvant-2 allowed the men to use the middle compartment as an airlock to reenter. Another spacewalk on 25 July finally ot the hatch to close properly.

The lesson learned from this was that on all future hatch designs, the hatch opened inwardly so that cabin air pressure could hold a hatch closed in the event of a latching failure.
