STS-6

STS-6 carried a crew of four – Paul J. Weitz, commander; Karol J. Bobko, pilot; Story Musgrave and Donald H. Peterson, both mission specialists. Using new spacesuits designed specifically for the Space Shuttle program, Musgrave and Peterson successfully accomplished the program's first extravehicular activity (EVA) on 7–8 April 1983, performing various tests in the orbiter's payload bay. Their spacewalk lasted 4 hours and 17 minutes. Although the 2,300-kilogram (5,000 lb) TDRS satellite was successfully deployed from Challenger, its two-stage booster rocket, the Inertial Upper Stage (IUS), tumbled out of control, placing the satellite into a low elliptical orbit.
