This attempted repair was the first unplanned spacewalk in NASA history.2 August07:155 hours12:15Salyut 7 EO-4Viktor SavinykhInstalled a third pair of solar arrays on exterior of Salyut 7.31 August7 hoursSTS-51-IDiscoveryWilliam FisherJames van HoftenVan 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.1 September4 hours26 minutesSTS-51-IDiscoveryWilliam FisherJames van HoftenCompleted 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.29 November5 hours32 minutesSTS-61-BJerry L. RossSherwood C.
