EVAs

Start Date/Time	Duration	End Time	Spacecraft	Crew	Remarks
26 May 00:40	40 minutes	01:20	CM-116 SLM-1	Paul J. Weitz	Using a 10-foot (3.0 m) long tool, Weitz stood in the open hatch of the Command Module (as Joe Kerwin held onto his legs) and tried to remove a strap preventing the release of a solar panel on Skylab.^[1]
7 June 15:15	3 hours 25 minutes	18:40	Skylab SLM-1	Pete Conrad Joseph P. Kerwin	Used long-handled cable cutters to remove debris that prevented the solar array system from deploying and then forced the solar array system to deploy, providing the Skylab with electrical power needed to operate.
19 June 10:55	1 hour 36 minutes	12:31	Skylab SLM-1	Pete Conrad Paul J. Weitz	Replaced exposed film cassettes with fresh film and repaired an electrical contact.
6 August 17:30	6 hours 31 minutes	7 August 00:01	Skylab SLM-2	Owen K. Garriott Jack R. Lousma	Erected a twin-pole solar shield to improve temperature control in Skylab, replaced film cassettes in the solar observatory and installed micrometeoroid detection panels.
24 August 16:24	4 hours 31 minutes	20:55	Skylab SLM-2	Owen K. Garriott Jack R. Lousma	Installed a new gyroscope selection box, and replaced the film in the solar observatory.
22 September 11:18	2 hours 41 minutes	13:59	Skylab SLM-2	Owen K. Garriott Alan Bean	Replaced the film on the solar observatory and collected the Thermal Coatings Experiment Panel for return to earth.^[2]
22 November 17:42	6 hours 33 minutes	23 November 00:15	Skylab SLM-3	Edward Gibson William R. Pogue	Replaced the film on the solar observatory and repaired the antenna for the earth resources experiment package.
25 December 16:00	7 hours 1 minute	23:01	Skylab SLM-3	Gerald P. Carr William R. Pogue	Used the extreme ultraviolet electronographic camera and the coronagraph contamination camera to photograph Comet Kohoutek. They also replaced the film on the solar observatory.
29 December 17:00	3 hours 29 minutes	20:29	Skylab SLM-3	Gerald P. Carr Edward Gibson	Photographed Comet Kohoutek as it appeared from behind the sun and recovered the Thermal Control Coatings Experiment panel.
