太空行走
[ 2008-09-26 09:10 ]
神舟七號(hào)載人航天飛行任務(wù)總指揮部決定,神舟七號(hào)飛船將于9月25日21時(shí)07分至22時(shí)27分擇機(jī)發(fā)射,進(jìn)行載人航天飛行。飛船運(yùn)行期間,兩名航天員進(jìn)入軌道艙,分別穿著我國(guó)研制的“飛天”艙外航天服和從俄羅斯引進(jìn)的“海鷹”航天服進(jìn)行出艙活動(dòng)準(zhǔn)備。其中,一名航天員出艙進(jìn)行艙外活動(dòng),回收在艙外裝載的試驗(yàn)樣品裝置。
請(qǐng)看中國(guó)日?qǐng)?bào)網(wǎng)站的消息:
Before the spacewalk, the astronaut shouldering the historic task will need the help of another to put on a 120kg, non-powered spacesuit for the extra vehicular activity (EVA).
在太空行走之前,承擔(dān)此項(xiàng)歷史重任的航天員要先在另一名航天員的幫助下穿上重達(dá)120公斤的無(wú)動(dòng)力艙外活動(dòng)航天服。
上述報(bào)道中,extra vehicular activity 就是“艙外活動(dòng)”的英文表達(dá),簡(jiǎn)稱EVA,是我們通常所說(shuō) spacewalk(太空行走)的專業(yè)說(shuō)法。
WIKI百科介紹說(shuō)Extra-vehicular activity (EVA) is work done by an astronaut away from the Earth and outside of a spacecraft. The term most commonly applies to an EVA made outside a craft orbiting Earth (a spacewalk) but also applies to an EVA made on the surface of the Moon (a moonwalk),由此可見(jiàn),“艙外活動(dòng)”(EVA)還具體分為spacewalk(太空行走)和moonwalk(月球行走)。
