语篇导读：作为“stem in 30”推广活动的一部分，美国宇航员通过视频向参观国家航空航天博物馆的学生们介绍了航天员在太空中的生活。
students from several washington-area schools had a chance to ask astronauts questions recently at the smithsonian national air and space museum as part of its "stem in 30" program.
in a live video from space, astronaut randy bresnik was ready to tell them what they wanted to know.
bresnik began a six-month stay on the international space station in july. the station's six-member crew (工作人员) has three americans. as they orbit (绕轨道飞行) about 250 miles above earth, they are doing tests about living and working in space.
part of their job is telling young people about the challenges and advantages of space travel, something you might do in your lifetime. bresnik has two children, ages 11 and 7, making him the most suitable astronaut to star in a "stem in 30" webcast. the 30-minute shows aim to attract students to stem subjects — science, technology, engineering and math — in fun, creative ways.
bresnik floated (漂浮) around the space station to show weightlessness. he showed how water forms bubbles (气泡) that also float if they leave their containers.
the space station travels five miles per second, circling earth every 1½ hours. because the astronauts see 16 sunrises and 16 sunsets every 24 hours, they depend on their watches to tell them when it's bedtime.
about 650 kids came to the smithsonian to see bresnik's live video.
"it was really cool," said emily steed, 11, a sixth-grader at providence elementary in fairfax county. "it's not every day you get to actually talk to an astronaut in space."
amina gasaway, 14, agreed. she's in ninth grade at washington's phelps high and she is interested in construction and engineering. seeing bresnik makes her want to become an engineer even more than before, she said.
