Due to non-separation of second stage Intelsat 603 was released from its perigee motor into a Low Earth orbit. Space Shuttle Endeavour on mission STS-49 attached a new perigee motor which boosted the satellite to geosynchronous orbit.
Originally launched as Westar 6 by Space Shuttle Challenger in February 1984 on mission STS-41-B. Was stranded in an incorrect orbit and was recovered in November 1984 by Space Shuttle Discovery on mission STS-51-A. Westar 6 was refurbished and sold to AsiaSat who renamed it AsiaSat 1.
Originally launched in February 1984 as Palapa B2 by Space Shuttle Challenger on mission STS-41-B. Was stranded in an incorrect orbit and was recovered in November 1984 by Space Shuttle Discovery on mission STS-51-A.
Installed new star tracker sensors launched in the Kvant-2 module onto Kvant-1.

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.
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.

Mir EO-5 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.

Mir EO-5 Kvant-2

Conducted more tests of the SPK. Viktorenko reached as far as 45 metres (148 ft) from Mir.
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.

Mir EO-6 Kvant-2

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.
