SPACE is a lonely place. Hundreds of thousands of kilometers from home, astronauts have a hard life. It stands to reason that, once in a while, they need to have a good cry. But this is a lot harder than it sounds.
We still know very little about space, and about living in zero gravity. In fact, we are discovering new things every time astronauts take to the skies (and beyond). As The Atlantic reported in January, crying is not all that simple in space. This is because when a person normally cries,  gravity makes their tears move downwards. But in a spacecraft, this is not the case. Here, there is no gravity, which is why we so often see pictures of astronauts floating around. This means that, strangely, when you cry your tears have nowhere to go. As a result, they just stick to your eyes.
In May 2011, astronaut Andrew Feustel experienced this. “Tears,” as he said, “don’t fall off your eye… they just kind of stay there. ” This can be quite painful. In space, your eyes get very dry, and the added moisture is irritating (气人的). Sometimes, things get even weirder(更怪异的). The astronaut Ron Parise told The Atlantic that when tears get big enough, they “break free of the eye and float around”.
No one can be quite sure why we cry. Why should water in our eyes have anything to do with feeling sad? If you stop to think about it, crying is a very strange thing indeed. And now, thanks to the wonders of space, it just got even stranger.

Sitting at the dinner table and sleeping in bed is normal (正常的 ) for you. How is an astronaut's (宇航员) life in Shenzhou Vl different from yours.'?

Eating: Astronauts in. a space*hip face a choice because of no gravity (引力). They may pick their food, use their hands and put it into their mouths. Or they may let the food stay in the air. Then they float (漂浮) to the food and get it with their mouths. Astronauts have to re-member to close their mouths tightly (紧紧地) while eating. Any crumb (碎屑) could cause big trouble. Bits of food that stay in the air can go into astronauts' noses when they are breathing.

Sleeping: Shenzhon VI astronauts sleep on the wall of the spaceship. People float in a spaceship where there isn't any gravity. So scientists fix (固定) sleeping bags to tbe wall tohelp astronauts.
