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. ||||||

## Deep-space rendezvous

There were no deep-space rendezvous in 1984.

## EVAs

| 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. |
| 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. |
| 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. |
| 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. |

| 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. Sullivan was the first American women and the second women in history to conduct an EVA. |
| 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. |
| 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. |
