STS-49

STS-49 was the maiden flight of the Space Shuttle Endeavour. The primary goal of its nine-day mission was to retrieve a Intelsat VI satellite (Intelsat 603, which failed to leave low earth orbit two years before), attach it to a new upper stage, and relaunch it to its intended geosynchronous orbit. After several attempts, the capture was completed with a three-person extra-vehicular activity, the first time that three people from the same spacecraft walked in space at the same time. It would also stand until STS-102 in 2001 as the longest EVA ever undertaken.
