Ask for fun with astronauts

How do you drink water in the universe? What do you do when you're sick? Waste they left to go? Is the space suit easy . Here is the answer of the astronauts about these interesting questions.

- How do you drink water in the universe?

Col Robert ' Bob ' Springer, USMC (retired):

Drinking water in the universe is easy, and exciting! Drinking is the same as on earth, but in space, you don't need to use a cup to hold. In fact, you can pour liquid into space (in the shuttle), the surface tension will make it have a round ball shape, and you can put a straw in the middle of this sphere and drink it.

- Under the right conditions, can the dolphin swim in the universe?

Col Robert 'Bob' Springer, USMC (retired):

- No, of course. A dolphin needs a liquid environment to swim, as well as to survive. Without water, dolphins will float in the universe like humans, but it cannot swim.

- In the universe, do you have free time and how do you use it?

Guion S. 'Guy' Bluford, Jr., Col USAF (retired):

No free time is planned during flights. Astronauts sometimes have a break when flying into space. During those times, they can do everything they want to do, like taking pictures, looking out the window, or doing extra work to support the work.

- What is the funniest thing you ever met while in space?

Col Donald ' Don ' McMonagle, USAF (retired):

- Being so attached to a sleeping bag by a colleague that I couldn't escape without damaging the sleeping bag or asking for help.

- Why do you have to wear a traveling suit, and are they comfortable?

CAPT Winston Scott, USN (retired):

We have to wear travel suits to maintain life. Without this outfit, we could not breathe in the universe. In addition, the suit also helps astronauts avoid strong temperature fluctuations in space. Without it, they could be frozen or burned because of different temperature extremes. This suit is quite large, bulky and quite inconvenient. It weighs about 136-158 kg when on earth.

- How to bathe in the universe?

Charles Walker:

The shuttle and the international station all fly in orbit around the earth in a " free-fall " state, meaning that the force that holds them, and everything inside them, on orbit is balanced at zero. is the "weightless" state that we talk about. Everything that people do on the compartments does not seem to be heavy and suspended.

Therefore, when we need to use the bathroom, we have to pay attention to some things. The bathroom here looks very similar to the earth. But when using it, we had to tie the rope over our feet to keep ourselves still on the seat. The fans below the room are turned on to create a top-down spray, passing people and pulling liquids and solid waste away. The liquid is then poured out of space and they will vaporize into atoms. Solid waste is frozen and brought back to earth.

- If the astronaut is ill, do they have any hospitals to take care of the universe?

Col Robert 'Bob' Springer, USMC (retired):

- If you're sick, there's nothing like a hospital there to take care of you. But you must have medical assistance on board. In many flights, one must include a doctor, or if not, one of the remaining astronauts will be trained in medical procedures. In fact, I did this on my second flight, and there was even an opportunity to inject a sick colleague.

- From the universe, how he returned to earth

MajGen Charles F. Bolden, USMC (retired):

- When ready to return to earth, we turn on the train so it can fly back. In the shuttle, we will turn on two system engines to slow the speed down to about 300 miles per hour. The reduction in orbit speed allows gravity to pull the ship back to Earth. Once out of orbit, the ship will glide to land again on the ground. The separation from the orbit is conducted about halfway around the world.
