StewartMcCandless 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 February6 hours17 minutesSTS-41-BChallengerBruce McCandless IIRobert L. StewartContinued testing the MMUs and practice with tools and procedures to be used with recovery and repair of the SMM satellite.8 April14:182 hours38 minutes16:56STS-41-CChallengerGeorge NelsonJames van HoftenNelson 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 April08:586 hours44 minutes15:42STS-41-CChallengerGeorge NelsonJames van HoftenCompleted repair of the SMM satellite and then continued testing of the MMU.23 April04:314 hours20 minutes08:46Salyut 7 EO-3Leonid KizimVladimir SolovyovInstalled a new ladder to reach the ruptured Main Oxidizer Line on Salyut 7.
