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. That's where the International Space Station orbits the Earth, with six astronauts living and working on board, for months at a time.

对你的生活感到无聊吗？梦想着不同的东西？当我有这种感觉时，我抬起头来想知道在我头顶 400 公里处的生活会是什么样子。那是国际空间站环绕地球运行的地方，有六名宇航员在船上生活和工作，一次持续数月。

How do they sleep? They spend the night floating in a sleeping bag inside a small cubicle on the ceiling. 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. I don't have any sensation in my head that tells me I'm upside down."

他们怎么睡觉？他们整夜漂浮在天花板上一个小隔间里的睡袋里。美国宇航员苏妮塔·威廉姆斯解释说：“它就像一个小电话亭，但它很舒服，我翻身睡觉也没有关系。我的脑海里没有任何感觉告诉我我倒立了.”

Brushing your teeth in a place where you can't have a tap or a sink can be a challenge. Can you imagine the mess that running water would make in zero gravity? 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.

在没有水龙头或水槽的地方刷牙可能是一个挑战。你能想象流水在零重力下会造成的混乱吗？加拿大宇航员克里斯·哈德菲尔德用一根吸管从密封袋中取出一大团水，放到普通牙刷上，并加入一点牙膏——完成后他必须吞下。

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.

日常锻炼必不可少。缺乏重力会使骨骼更脆，肌肉会失去力量——因此鼓励宇航员每天至少锻炼两个小时。

The role of astronauts in the International Space Station is to act as lab technicians for scientists back on Earth. So they spend their time maintaining their environment and performing and monitoring experiments in a confined space about the size of a Boeing 747. 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.

宇航员在国际空间站中的作用是充当科学家返回地球的实验室技术人员。因此，他们将时间花在维护环境、执行和监控与波音 747 差不多大小的密闭空间中的实验上。几乎每项任务都由任务控制中心精心计划——尽管大多数宇航员在开始的第一天都在丢东西，直到他们习惯了坚持他们用魔术贴、胶带或夹子粘在墙上的所有东西。

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. Wow! Absolutely breathtaking!

他们最宝贵的特权之一是“办公室”的景色，那里有一个巨大的蓝色球，坐在黑暗的太空中。哇！绝对令人叹为观止！
