PAM failures led to Westar 6 and Palapa B2 being stranded in Low Earth orbit. The satellites were subsequently retrieved by Space Shuttle Discovery during mission STS-51-A in November and were returned to Earth for refurbishment. Westar 6 was sold to AsiaSat and renamed AsiaSat 1, and launched by a Chinese Long March 3 carrier rocket on 7 April 1990. Palapa B2 was renamed Palapa B2R and was launched by an American Delta II 6925-8 carrier rocket on 13 April 1990.

Start date/time	Duration	End time	Spacecraft	Crew	Remarks
7 February	5 hours 55 minutes		STS-41-B Challenger	Bruce McCandless II Robert L. Stewart	McCandless and Stewart rode on the Crewed Maneuvering Unit (MMUs) during the first untethered EVAs in history. Both astronauts practiced using tools and procedures for the planned capture and repair of the Solar Maximum Mission (SMM) satellite to be performed in a subsequent flight.[5]
9 February	6 hours 17 minutes		STS-41-B Challenger	Bruce McCandless II Robert L. Stewart	Continued testing the MMUs and practice with tools and procedures to be used with recovery and repair of the SMM satellite.[5]
8 April 14:18	2 hours 38 minutes	16:56	STS-41-C Challenger	George Nelson James van Hoften	Nelson rode the MMU to the SMM satellite. Van Hoften stood by in the payload bay to provide any needed assistance. After three unsuccessful attempts to capture the SMM with the Trunnion Pin Acquisition Device (TPAD) tool and one attempt to grab the satellite by hand, the spacewalkers returned to Challenger. The SMM was recovered the next day with the RMS.[6]
11 April 08:58	6 hours 44 minutes	15:42	STS-41-C Challenger	George Nelson James van Hoften	Completed repair of the SMM satellite and then continued testing of the MMU.[7]
23 April 04:31	4 hours 20 minutes	08:46	Salyut 7 EO-3	Leonid Kizim Vladimir Solovyov	Installed a new ladder to reach the ruptured Main Oxidizer Line on Salyut 7. First of five EVAs to conduct the repair.
26 April 02:40	4 hours 56 minutes	07:40	Salyut 7 EO-3	Leonid Kizim Vladimir Solovyov	Removed installation and installed a valve in the spare oxidizer line. Second of five EVAs to repair the Main Oxidizer Line on the station.
29 April 01:35	2 hours 45 minutes	04:20	Salyut 7 EO-3	Leonid Kizim Vladimir Solovyov	Installed a bypass line around the damaged section of the Main Oxidizer Line on the station. Third of five repair EVAs.
3 May 23:15	2 hours 45 minutes	4 May 02:00	Salyut 7 EO-3	Leonid Kizim Vladimir Solovyov	Installed a second bypass line and replaced thermal insulation at the Main Oxidizer Line of the station. Fourth of five repair EVAs.
18 May 17:52	3 hours 5 minutes	20:57	Salyut 7 EO-3	Leonid Kizim Vladimir Solovyov	Installed two new solar arrays onto the space station.
25 July 14:55	3 hours 35 minutes	18:29	Salyut 7 EP-4	Vladimir Dzhanibekov Svetlana Savitskaya	Tested the URI multi-purpose tool with several metal samples. Savitskaya became the first women in history to perform an EVA.
8 August 08:46	5 hours	13:46	Salyut 7 EO-3	Leonid Kizim Vladimir Solovyov	Using a pneumatic press tool delivered by Soyuz T-12, the cosmonauts completed the fifth and final EVA to repair the damaged Main Oxidizer Line of the station by crimping the ends of the ruptured pipe.
11 October 15:38	3 hours 29 minutes	19:05	STS-41-G Challenger	David Leestma Kathryn Sullivan	Demonstrated the use of the Orbital Refueling System, including the installation of an ORS valve maintenance kit.[8] Sullivan was the first American women and the second women in history to conduct an EVA.[9]
12 November 13:25	6 hours	19:25	STS-51-A Discovery	Joseph P. Allen Dale Gardner	Allen rode the MMU to the Palapa B2 satellite and retrieved it into the payload bay. Gardner and Allen then secured the satellite in the payload bay for return to Earth.[10]
14 November 11:09	5 hours 42 minutes	16:51	STS-51-A Discovery	Joseph P. Allen Dale Gardner	Gardner rode the MMU to the Westar 6 satellite and retrieved it into the payload bay. Allen and Gardner then secured the satellite in the payload bay for return to Earth.[10]
