16 April | 3 hours 6 minutes |
STS-51-D Discovery |
Jeffrey A. Hoffman S. David Griggs |
Installed an improvised switch-pulling tool, called the Flyswatter, on the RMS robotic arm. The Flyswatter was used in an effort to push the sequencer start lever on the Leasat-3 in the proper position for deployment. [4] This attempted repair was the first unplanned spacewalk in NASA history. [5] | |
2 August 07:15 |
5 hours | 12:15 | Salyut 7 EO-4 |
Vladimir Dzhanibekov Viktor Savinykh |
Installed a third pair of solar arrays on exterior of Salyut 7. |
31 August | 7 hours 20 minutes |
STS-51-I Discovery |
William Fisher James van Hoften |
Van Hoften rode the RMS to capture the Leasat 3 satellite and pulled it into payload bay. Fisher and Van Hoften secured and started repairs on the satellite in the payload bay. The retrieval was complicated by a malfunction of the RMS that made operation of the arm more complicated. [6] | |
1 September | 4 hours 26 minutes |
STS-51-I Discovery |
William Fisher James van Hoften |
Completed repairs on the Leasat 3 satellite. Then Van Hoften, riding the RMS, heaved the satellite out of the payload bay, imparting the required spin needed to fire the perigee motor. [6] | |
29 November | 5 hours 32 minutes |
STS-61-B Atlantis |
Jerry L. Ross Sherwood C. Spring |
Practiced construction techniques in the payload bay and assembled and disassembled the two experimental EASE/ACCESS structures. [7] | |
1 December | 6 hours 41 minutes |
STS-61-B Atlantis |
Jerry L. Ross Sherwood C. Spring |
Conducted supplementary experiments on the EASE and ACCESS structures, including a test of the RMS to aid in the construction experiments. [7] |
