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(jī)發(fā)射,進(jìn)行載人航天飛行。飛船運行期間,兩名航天員進(jìn)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(jìn)的“海鷹”航天服進(jìn)行出艙活動準(zhǔn)備。其中,一名航天員出艙進(jìn)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(dān)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(dá)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(dá),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)。
