3 hours 6 minutes  | 
9 January 02:14  | 
Mir EO-24 | 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.[1] | ||
| 14 January 21:12  | 
3 hours 52 minutes  | 
15 January 01:04  | 
Mir EO-24 | 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.[2] | ||
| 1 April 13:35  | 
6 hours 40 minutes  | 
20:15 | Mir EO-25 | 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.[3] | ||
| 6 April 13:35  | 
4 hours 15 minutes  | 
17:50 | Mir EO-25 | 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.[4] | ||
| 11 April 09:55  | 
6 Hours 25 minutes  | 
16:20 | Mir EO-25 | 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.[5] | Dismantling of the Rapana structure was not completed.[6] | |
| 17 April 07:40  | 
6 Hours 33 minutes  | 
14:13 | Mir EO-25 | Removed two structures and secured them to exterior surfaces and repositioned the new thrust engine (VDU) for future use.[6] | ||
| 22 April 05:34  | 
6 Hours 21 minutes  | 
11:55 | Mir EO-25 | Completed installation of the new VDU thruster unit on top of the Sofora boom.[7] | ||
| 15 September 20:00  | 
30 minutes | 20:30 | Mir EO-26 | Internal spacewalk in the depressurised Spektr module to connect electrical and control cables to the solar array servo motor.[8] | ||
| 10 November 19:24  | 
5 hours 54 minutes  | 
11 November 01:18  | 
Mir EO-26 | Deployed Sputnik-41, deployed a French "meteorite trap" intended to catch some dust from the upcoming Leonids meteor shower.[9] | ||
| 7 December 22:10  | 
7 hours 21 minutes  | 
8 December 05:31  | 
STS-88 ISS Endeavour  | 
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).[10] | First ISS assembly EVA | |
| 9 December 20:33  | 
7 hours 2 minutes  | 
10 December 03:35  | 
STS-88 ISS Endeavour  | 
Installed two box-like antennas on the outside of the Unity module that are part of the S-band early communications system.[11] | ||
| 12 December 20:33  | 
6 hours 59 minutes  | 
13 December 03:32  | 
STS-88 ISS Endeavour  | 
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.[12] | ||
