When they make it, China will become the third country in the world who is able to conduct extra-vehicular activity in space following the former Soviet Union and the United States. 如果此次太空行走成功,中国将成为世界上继美国和前苏联之后第三个能够进行太空出舱活动的国家。
During the4-day space journey, one of the astronauts from China will float out of the cabin to conduct extra-vehicular activity in space. 在随后的飞行过程中,我国航天员将首次进行空间出舱活动。
The ability to do what is also called " extra-vehicular activity " is essential for China's long-term goals of an orbiting station in the next decade and possibly a visit to the moon, Reuters reported. 而据路透社报道,中国长期以来一直致力于在10年内建立空间站,探访月球。而舱外活动的技术对这些目标尤为重要。
Jonathan Miller, who works with the Johnson Space Center's Extra-Vehicular Activity(EVA) Office in Houston and came here to see the last landing, says his concern goes well beyond the issue of job losses. 而约翰逊•米勒表明自己担心的不仅仅是失业问题。他在休斯敦约翰逊航天中心宇航员舱外活动办公室工作,也亲临现场观看了航天飞机的最后一次着陆。
