Sharon Christa McAuliffe, right, and Barbara R. Morgan, participating in the Teacher-in-Space Project, team up with Bob Mayfield, a JSC aerospace educations specialist, to preview some experiments in zero-G. A KC-135 aircraft flies a special pattern to provide series of brief periods of weightlessness. McAuliffe, prime crew member for STS-51L, injects a hydroponic solution into a cylinder to review one of the experiments planned for the flight. Morgan is backup for McAuliffe on that mission.
