Modified the docking node for the arrival of the Kristall module.26 January12:093 hours2 minutes15:11Mir EO-5Kvant-2Alexander ViktorenkoAleksandr SerebrovTested 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.1 February08:154 hours59 minutes13:14Mir EO-5Kvant-2Alexander ViktorenkoAleksandr SerebrovTested the SPK "flying armchair", analogous to NASA's MMU. The SPK did not fly free, but remained tethered to Kvant-2 during the tests.5 February06:083 hours45 minutes09:53Mir EO-5Kvant-2Alexander ViktorenkoAleksandr SerebrovConducted more tests of the SPK. Viktorenko reached as far as from Mir.17 July13:067 hours15 minutes20:22Mir EO-6Kvant-2Anatoly SolovyevAleksandr BalandinAt 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.26 July11:153 hours31 minutes14:46Mir EO-6Kvant-2Anatoly SolovyevAleksandr BalandinTransmitted 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.29 October21:452 hours45 minutes00:30Mir EO-7Kvant-2Gennadi ManakovGennady StrekalovAfter 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.
