EVAs

Start Date/Time	Duration	End Time	Spacecraft	Crew	Remarks
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.^[1] This attempted repair was the first unplanned spacewalk in NASA history.^[2]
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.^[3]
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.^[3]
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.^[4]
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.^[4]
