[双语]55岁女教师上太空零重力授课

2007/8/21镜像同步0 回复

The first teacher in space taught her first lesson in zero-gravity Tuesday, answering questions from school children in Idaho from the orbiting International Space Station hundreds of miles above Earth. Barbara Morgan, flanked by crewmates, talked via videolink for 25 minutes to children in Idaho, where Morgan taught at a primary school early in her career. Morgan, now 55, trained as understudy to fellow teacher Christa McAuliffe in the 1980s as the NASA hoped that sending a teacher into space would fire the imaginations of millions and keep up support for its shuttle program. But McAuliffe never made it to space because the Challenger shuttle exploded in 1986. Twenty-two years later, Morgan has fulfilled the aim. She fielded questions such as how fast a baseball travels in space and how to drink in weightlessness. She and her fellow astronauts demonstrated, throwing real balls and swallowing floating bubbles of liquid. Asked how astronauts exercise in space, Morgan grabbed one of her colleagues and lifted him.
