| Start Date/Time | Duration | End Time | Spacecraft | Crew | Remarks | |
|---|---|---|---|---|---|---|
| 17 January | 4 hours | STS-54 |  Gregory J. HarbaughMario Runco, Jr. | Tested space station construction techniques and mobility techniques.[1] | ||
| 19 April 17:15 | 5 hours 25 minutes | 22:40 | Mir EO-13 Kvant-2 |  Gennadi Manakov | Used the Strela boom to install an electric motor on the Kvant-1 module for solar arrays originally installed on the Kristall module. After the installation, Poleshchuk noticed that one of the handles on the Strela boom had become loose and drifted away from Mir. The loss of the Strela handle meant the next EVA would have to be delayed until a new handle could be lifted to orbit the next Progress supply launch. | |
| 18 June 17:25 | 4 hours 33 minutes | 21:58 | Mir EO-13 Kvant-2 | Gennadi ManakovAleksandr Poleschuk | After receiving the replacement part, Manakov and Poleshchuk first repaired the Strela boom and then installed the second electric drive for the solar array. | |
| 25 June | 5 hours 50 minutes | STS-57 Endeavour | G. David LowPeter Wisoff | Helped secure the antenna on the captured EURECA satellite in its stored position for return to Earth. Then both spacewalkers practiced construction maneuvers on the RMS.[2] | ||
| 16 September 05:57 | 4 hours 18 minutes | 10:16 | Mir EO-14 Kvant-2 | Vasily TsibliyevAleksandr Serebrov | Began assembly of the experimental Rapana truss structure. | |
| 16 September 08:40 | 7 hours 5 minutes | 15:45 | STS-51 | James H. NewmanCarl E. Walz | Carried out tests on tools, tethers, and a foot restraint system in anticipation of the repair of the Hubble Space Telescope. A stuck tool chest lid slowed the closeout of spacewalk for at least 45 minutes.[3] | |
| 20 September 03:51 | 3 hours 13 minutes | 07:05 | Mir EO-14 Kvant-2 | Vasily TsibliyevAleksandr Serebrov | Completed assembly of the Rapana truss. | |
| 28 September 00:57 | 1 hour 52 minutes | 02:48 | Mir EO-14 Kvant-2 | Vasily TsibliyevAleksandr Serebrov | Inspected the Mir exterior for damage from the recent Perseid meteoroid shower. The most notable damage they found was a 5mm hole on one of the solar arrays. | |
| 22 October 15:47 | 38 minutes | 16:25 | Mir EO-14 Kvant-2 | Vasily TsibliyevAleksandr Serebrov | Continued their inspection of the Mir exterior for damage from the Perseids. | |
| 29 October 13:38 | 4 hours 12 minutes | 17:50 | Mir EO-14 Kvant-2 | Vasily TsibliyevAleksandr Serebrov | Completed their inspection of the entire outer surface of the Mir. They observed several marks on the hull, there were no complete penetrations. The spacewalking team did notice an unidentified piece of metal drifting by the orbital complex during their inspections. | |
| 5 December 03:44 | 7 hours 54 minutes | 11:38 | STS-61 Endeavour | Story MusgraveJeffrey A. Hoffman | HST servicing: Replaced two sets of gryoscopes and electrical control units, as well as a set of eight fuses. The spacewalks had considerable difficulty closing the latches on the doors due to thermal expansion of the closure bolts. Before re-entering the shuttle, the team prepared the payload bay for the next EVA.[4] | |
| 6 December 03:29 | 6 hours 36 minutes | 10:05 | STS-61 Endeavour | Kathryn C. ThorntonThomas Akers | HST servicing: Thorton rode the RMS to handle the solar arrays while Akers made the cable connections as the team replaced two solar arrays on Hubble. One array was discarded into space, and one array was furled and stowed for return to earth. | |
| 7 December 03:35 | 6 hours 47 minutes | 10:22 | STS-61 Endeavour | Story MusgraveJeffrey A. Hoffman | HST servicing: Replaced the WFPC with WFPC 2 and two magnetometers. | |
| 8 December 03:13 | 7 hours 21 minutes | 10:03 | STS-61 Endeavour | Kathryn C. ThorntonThomas Akers | HST servicing: Replaced Hubble's High Speed Photometer (HSP) with the Corrective Optics Space Telescope Axial Replacement (COSTAR). This replacement fixed the spherical aberration in Hubble's mirror. The HSP was stowed for return to earth. | |
| 9 December 03:30 | 7 hours 21 minutes | 10:51 | STS-61 Endeavour | Story MusgraveJeffrey A. Hoffman | HST servicing: Replaced the electronics for the solar array drive motors. They also placed some made-on-Endeavour covers over the new magnetometers to protect them from debris. |
