CREW TRAINING - STS-33/51L (ZERO-G)

S85-42474 (16 Oct. 1985) --- A KC-135 aircraft provides a brief period of weightlessness as a preview for a teacher, in training to fly onboard a space shuttle for the Teacher-in-Space Project, and her backup. Sharon Christa McAuliffe (center frame), STS-51L prime crew member, and Barbara Morgan, her backup, monitor an experiment involving magnetic effects - one of the tests to be performed on the STS-51L flight. The experiment uses a control box, a square receptacle containing rubber tubing, stainless steel rod, a filter with desiccant, soft iron wire and a magnet. Photo credit: NASA
