INTERNATIONAL SPACE STATION -- Teacher-astronaut Barbara Morgan transformed the space shuttle and space station into a classroom Tuesday for her first education session from orbit.
The lesson fulfilled the legacy of Christa McAuliffe with joy and also some sadness. Morgan was McAuliffe's backup for the doomed 1986 flight of Challenger.
Hundreds of youngsters jammed the Discovery Center of Idaho in Boise to talk with Morgan.
One child wanted to know about exercising in space. In response, Morgan lifted the two large men floating alongside her, one in each hand, and pretended to be straining. Another youngster wanted to see a demonstration of drinking in space.
Meanwhile, NASA is still deciding whether to send astronauts out to fix a gouge on the belly of shuttle Endeavour.
