Working in space

[00:00.36] Bored with your life? Dreaming of something different? When I feel like that I look up and wonder what life would be like 400km above my head. 厌倦了你的生活？梦见不一样的东西？当我有这种感觉时，我会抬起头，想知道在我头顶 400 公里处的生活会是什么样子。

[00:14.13] That's where the International Space Station orbits the Earth, with six astronauts living and working on board, for months at a time.那是国际空间站绕地球运行的地方，有六名宇航员在船上生活和工作，每次几个月。

[00:24.15] How do they sleep? They spend the night floating in a sleeping bag inside a small cubicle on the ceiling. 他们怎么睡觉？他们在天花板上的一个小隔间里的睡袋里过夜。

[00:33.16] American astronaut Sunita Williams explains: "It's like a little phone booth but it's pretty comfy and it doesn't matter if I turn over and sleep upside down. 美国宇航员苏尼塔·威廉姆斯解释说：“它就像一个小电话亭，但很舒服，我翻身倒睡也没关系。

[00:45.18] I don't have any sensation in my head that tells me I'm upside down."我脑子里没有任何感觉告诉我我颠倒了。”

[00:51.45] Brushing your teeth in a place where you can't have a tap or a sink can be a challenge. 在没有水龙头或水槽的地方刷牙可能是一项挑战。

[00:57.20] Can you imagine the mess that running water would make in zero gravity? 你能想象在零重力下流水会造成什么混乱吗？

[01:02.96] Canadian astronaut Chris Hadfield uses a straw to put a big blob of water from a sealed bag onto an ordinary toothbrush and adds a little toothpaste - which he has to swallow when he's done.加拿大宇航员克里斯·哈德菲尔德（Chris Hadfield）用吸管从密封袋中取出一大团水到普通牙刷上，然后加入少许牙膏——完成后他必须吞下。

[01:18.24] Daily exercise is essential. The lack of gravity makes bones more brittle and muscles lose strength – so astronauts are encouraged to work out for at least two hours a day.日常锻炼是必不可少的。缺乏重力会使骨骼更加脆弱，肌肉也会失去力量——因此鼓励宇航员每天至少锻炼两个小时。

[01:32.52] The role of astronauts in the International Space Station is to act as lab technicians for scientists back on Earth. 宇航员在国际空间站的作用是为地球上的科学家充当实验室技术员。

[01:40.28] So they spend their time maintaining their environment and performing and monitoring experiments in a confined space about the size of a Boeing 747.因此，他们将时间花在维护环境，并在波音 747 大小的密闭空间中进行和监控实验。

[01:52.05] Almost every task is carefully planned by mission control - although most astronauts spend their first days losing stuff until they get used to sticking everything they use to the walls with Velcro, duct tape or clips.几乎每一项任务都由任务控制中心精心计划——尽管大多数宇航员在第一天会丢失东西，直到他们习惯用魔术贴、胶带或夹子将他们使用的所有东西粘在墙上。

[02:08.58] One of their most valued perks is the view from "the office", dominated by that gigantic blue ball down there, sitting in the darkness of space. 他们最看重的好处之一是“办公室”的视野，由下面那个巨大的蓝色球主宰，坐在黑暗的太空中。

[02:20.85] Wow! Absolutely breathtaking!哇！绝对令人叹为观止！
