61A-S-135 (5 Nov 1985) --- Two school teachers in training at the Johnson Space Center got their first ?real time? exposure to a Space Shuttle mission as they monitor activity aboard the Spacelab D-1 science module from the mission control center. Sharon Christa McAuliffe (frame center) and Barbara R. Morgan are briefed by Terry White at the Public Affairs console during a television downlink from the Earth-orbiting Space Shuttle Challenger. McAuliffe is scheduled to fly as teacher/citizen observer on the STS 51-L mission early next year; and Morgan is in training as her backup.
