Shuttle Discovery astronauts have made the first of two spacewalks this week to carry out maintenance tasks on the International Space Station (ISS). 这个星期发现号航天飞机宇航员已经做出了两次太空漫步中的首次漫步,去执行国际空间站的维护任务

Steve Bowen and Alvin Drew spent six-and-a-half hours outside the orbiting platform, preparing it for the installation of a new store room and moving a faulty coolant pump. 斯蒂夫-波恩和阿尔韦恩-朱在轨道运行平台以外花了6个半小时进行维修;安装一个新储存室,取走一台有故障的冷却液泵。

Discovery arrived at the ISS on Saturday. 发现号航天飞机于星期六到达国际空间站。

It is the ship's final mission into space before being retired to a museum. 这是发现号退役到博物馆前的最后一次太空使命。

Bowen is making a small piece of history, himself. He was called up late for the mission following a bicycle crash injury to the assigned lead spacewalker Tim Kopra. 波恩正在自己撰写一个小篇幅的历史。他在一次自行车事故中受了伤,以后,被指定提为像提姆-考波拉一样的太空行走人士,通过太空行走去完成使命。

It means Bowen is on consecutive shuttle trips having flown on Atlantis in May last year - the first time that has ever happened. 这意味着去年5月波恩在亚特兰蒂斯号飞船上飞行后的未间断飞行——这样的飞行还是第一次。

The US space agency (Nasa) said Monday's spacewalk was the 243rd by American astronauts and the 154th in support of ISS assembly and maintenance. 美国宇航局说星期一的太空行走的243rd是美国宇航员创造的,支持154th国际空间站的组装和维护。

Bowen and Drew relocated a broken ammonia pump, and they also moved some cabling to allow the permanent attachment to the station on Tuesday of the Italian-built logistics module known as Leonardo. 星期二,波恩和朱替换掉一台破损的氨泵。他们还走动铺设电缆将意大利制作的被称为莱奥纳多的后勤模块永久地安装到这个空间站。

The cylinder, which has been used down the years as a packing box for supplies in the orbiter's payload bay, would normally return to Earth with every shuttle mission, but for Discovery's flight it is being left on the station to provide extra storage space. 圆筒式航天飞机已经使用了多年,用作为向国际空间站提供物资的运载舱应该完成航天飞机使命,正常地回到地面。但是,发现号的飞行还是给国际空间站提供了额外的储存空间。

Bowen and Drew ended their walk by carrying out a Japanese request to "bottle" a sample of space vacuum in a metal container. 波恩和朱舱外行走执行了日本国的装瓶要求;将太空真空样品装入一个金属容器,然后结束太空行走。

The light-hearted project will see the capsule, signed by many astronauts, returned to Earth to go on public display. 这个轻松的计划将目睹太空舱返回到地面被许多人签名,继续向公众展示。

Nasa's mission control played the song Message in a Bottle by the British rock group The Police as the two Americans captured their sample of nothing. 美国宇航局地面指挥中心播放由英国摇滚乐团通过瓶中信传递的歌曲。两位很像美国人的警察没有捕获到样品。

Discovery is due back on Earth on Monday, 7 March. The orbiter is expected eventually to go to the Smithsonian Institution's Air and Space Museum. 三月七日星期一是发现号航天飞机返回地面的日子。人们期待着返回舱最终被送入史密森研究院航空航天博物馆。
