詞數：334 完成時間：7分鐘 難度：
yi so-yeon, an engineer from seoul, returned to earth on saturday after 11 days aboard the international space station (iss), along with russian cosmonaut yuri malenchenko and us astronaut peggy whitson.
a technical problem turned a routine (常規) return to earth into a sharper than usual descent (下降) that tested the group members' stamina and courage. they landed in the kazakh steppes ( 大草原) about 420km (260 miles) wide of their target.
"during the descent there was some kind of fire outside the soyuz capsule because we were going through the atmosphere," yi said.
"at first i was afraid, but the two other guys looked okay, so i tried to look okay too."
yi smiled and joked her way through a 10-minute news briefing at star city, the wooded sovietera cosmonaut training centre on the edge of moscow. however, malenchenko and whitson looked tired and thin after nearly six months in space. their answers were short and whitson needed support to balance when she walked. the 29-year-old yi has become famous in south korea since the take-off but she brushed this aside and said she has had little contact with friends or family since returning.
