| - | - | - | - | - | - | - |
| 8 January 23:08 | 3 hours 6 minutes | 9 January 02:14 | Mir EO-24 | Anatoly Solovyev Pavel Vinogradov | Repaired the damaged airlock sealing system, used the Strela boom to move across Mir and recover an American optical monitoring experiment. Checked the integrity of cable connects to several antennas. | |
| 14 January 21:12 | 3 hours 52 minutes | 15 January 01:04 | Mir EO-24 | Anatoly Solovyev David Wolf | Continued to make more repairs to the airlock hatch on Kvant-2 and used a handheld photo-reflectometer to inspect the exterior surface of the station. | |
| 1 April 13:35 | 6 hours 40 minutes | 20:15 | Mir EO-25 | Talgat Musabayev Nikolai Budarin | Installed a set of handrails and one of two-foot restraints on the outside of the Spektr module in preparation for the repair of the damaged solar array. | |
| 6 April 13:35 | 4 hours 15 minutes | 17:50 | Mir EO-25 | Talgat Musabayev Nikolai Budarin | Begin repair of the damaged Spektr solar panel. After installing a splint on the frayed panel, the spacewalkers had to quickly return to the airlock to handle a problem with station attitude control. | |
| 11 April 09:55 | 6 Hours 25 minutes | 16:20 | Mir EO-25 | Talgat Musabayev Nikolai Budarin | Jettisoned the external thruster engine (VDU) that had been located at the top of the Sofora boom and recover an experiment from the Rapana structure. | Dismantling of the Rapana structure was not completed. |
| 17 April 07:40 | 6 Hours 33 minutes | 14:13 | Mir EO-25 | Talgat Musabayev Nikolai Budarin | Removed two structures and secured them to exterior surfaces and repositioned the new thrust engine (VDU) for future use. | |
| 22 April 05:34 | 6 Hours 21 minutes | 11:55 | Mir EO-25 | Talgat Musabayev Nikolai Budarin | Completed installation of the new VDU thruster unit on top of the Sofora boom. | |
| 15 September 20:00 | 30 minutes | 20:30 | Mir EO-26 | Gennady Padalka Sergei Avdeyev | Internal spacewalk in the depressurised Spektr module to connect electrical and control cables to the solar array servo motor. | |
| 10 November 19:24 | 5 hours 54 minutes | 11 November 01:18 | Mir EO-26 | Gennady Padalka Sergei Avdeyev | Deployed Sputnik-41, deployed a French "meteorite trap" intended to catch some dust from the upcoming Leonids meteor shower. | |
| 7 December 22:10 | 7 hours 21 minutes | 8 December 05:31 | STS-88 ISS Endeavour | Jerry L. Ross James H. Newman | Connected computer and electrical cables between the Unity node, the two mating adapters attached to either end of Unity, and the Zarya Functional Cargo Block (FGB). | First ISS assembly EVA |
| 9 December 20:33 | 7 hours 2 minutes | 10 December 03:35 | STS-88 ISS Endeavour | Jerry L. Ross James H. Newman | Installed two box-like antennas on the outside of the Unity module that are part of the S-band early communications system. | |
| 12 December 20:33 | 6 hours 59 minutes | 13 December 03:32 | STS-88 ISS Endeavour | Jerry L. Ross James H. Newman | Checked on an insulation cover on a cable connection on the lower Pressurized Mating Adapter (PMA-2) to make sure it was fully installed, attached EVA tools on the side of Unity's upper mating adapter (PMA-1) in preparation for future EVAs, and inspected Orbiter Space Vision System targets on Unity. | |
