20:55 Mir EO-5 Alexander Viktorenko
Aleksandr Serebrov
Closed out experimental racks, either retrieving for return to earth, or discarding into space. Modified the docking node for the arrival of the Kristall module.

15:11 Mir EO-5
Kvant-2
Alexander Viktorenko
Aleksandr Serebrov
Tested the new Orlan-DMA spacesuit. This spacewalk team was the first use of the EVA airlock hatch on the Kvant-2 module. During the spacewalk a mooring post was attached outside the airlock, and a Kurs antenna was removed to enable future EVAs.

Kvant-2
Alexander Viktorenko
Aleksandr Serebrov
Tested the SPK "flying armchair", analogous to NASA's MMU. The SPK did not fly free, but remained tethered to Kvant-2 during the tests.

09:53 Mir EO-5
Kvant-2
Alexander Viktorenko
Aleksandr Serebrov
Conducted more tests of the SPK. Viktorenko reached as far as 45 metres (148 ft) from Mir.

20:22 Mir EO-6
Kvant-2
Anatoly Solovyev
Aleksandr Balandin
At the start of their EVA to repair torn insulation on the Soyuz TM-9, Solovyev and Balandin damaged the hatch on Kvant-2 by opening it before the airlock was completely depressurized. The spacewalking team repaired the insulation on Soyuz, but time constraints required returning to Kvant-2 before they collected their tools and ladders. Unable to securely close the damaged hatch, they used the center section of Kvant-2 as a back-up airlock.

Kvant-2
Anatoly Solovyev
Aleksandr Balandin
Transmitted images of the damaged hatch to TsUP, recovered the ladders and tools left outside earlier and removed debris lodged in the hinge of the airlock hatch, allowing the hatch to close and seal for repressurization.

After removing insulation around the damaged Kvant-2 hatch, they found the hatch to be more heavily damaged than previously understood. Although unable to completely repair the hatch, they added hardware to the hatch.
