The oxygen in the International Space Station will not run out. Because water can be decomposed into oxygen and nitrogen by electricity in the space station, nitrogen and carbon dioxide can also be decomposed into water and methane, so it can be circulated indefinitely. So you don't have to worry about the lack of these things. The only concern is electricity from solar energy. Now it seems that learning chemistry well is really useful. It was because of poor physics that I changed to liberal arts. I regret it when I think about it now.

It is weightless in space, mainly caused by gravity. Others, almost no change. An astronaut once joked that yesterday's coffee is tomorrow's coffee. Think about it. Is it a little queasy? What is even more unbearable is that your urine, waste water and sweat can be processed and recycled, just like that risky bell. Is it a little unbearable?

If you live in the space station, you will feel uncomfortable. There is nothing to miss except seeing the unexpected scenery in outer space. How beautiful the earth is, with mountains, water and Woods, and many good friends to play with. More importantly, you can play around, see different scenery, feel different customs and learn different knowledge. This is what I want. What kind of life do you want?

The beauty on earth can't be felt in space! As for whether everyone thinks so, definitely not! There is also a rich man who applied for the Mars landing plan. He wants to go to this barren Mars. What can he do if he can't come back? People may have considered this, but they just want to experience the difference. Do you want to experience it?
