太空行走
[ 2008-09-26 09:10 ]
神舟七號載人航天飛行任務(wù)總指揮部決定,神舟七號飛船將于9月25日21時07分至22時27分擇機發(fā)射,進行載人航天飛行。飛船運行期間,兩名航天員進入軌道艙,分別穿著我國研制的“飛天”艙外航天服和從俄羅斯引進的“海鷹”航天服進行出艙活動準備。其中,一名航天員出艙進行艙外活動,回收在艙外裝載的試驗樣品裝置。
請看中國日報網(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,承擔此項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120公斤的無動力艙外活動航天服。
上述報道中,extra vehicular activity 就是“艙外活動”的英文表達,簡稱EVA,是我們通常所說 spacewalk(太空行走)的專業(yè)說法。
WIKI百科介紹說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,“艙外活動”(EVA)還具體分為spacewalk(太空行走)和moonwalk(月球行走)。
