When astronauts meet100000 cute babies in kindergarten, why?

1. Where does your water come from? What if there is no water?

Astronaut A: The water in the space station comes from the earth, but it has been recycled in the space station. Sweat, urine and moisture we exhale will be collected and recycled. This is mainly due to the water circulation system of the space station, recycling.

Excuse me, can you jump high?

Astronaut A: We are in a weightless environment. We can jump as high as we want. There is no resistance.

What was your biggest challenge when you were in space?

Astronaut A: We have done enough training on the ground, and we can handle it calmly at work. Personally, the challenge mainly comes from life. For example, when we sleep, we always feel like sleeping standing up. We must put our hands in our sleeping bags when we sleep, or we will probably be scared by our waving hands when we wake up.
