How to eat and sleep on other universes in Earth?

Learn about the exciting outer space through the words of a NASA astronaut.

Astronauts are always a hot topic on the screen or the world's top selling press publication.

Have you ever seen a lot of pictures of astronauts floating in the cabin, eating food in small tubes like toothpaste, drinking water floating in the form of spheres? And you always think, that is the life of space astronauts.

However, the following share of astronaut Marsha Ivins will show you another corner of life in outer space.

When the spacecraft takes off .

Nothing will stop the emotions from surging through you when you leave Earth. The first thing you will definitely do when the spacecraft is launched, is to look back at the Earth through the window. It must be a thrilling and choking feeling that will envelop you.

The moment the spacecraft is launched from the ground .

For the first time on the spacecraft, you will have a feeling of anxiety and a little 'panic'. It will take about 2 hours for the preparation to take off and you will not know what to do during that time period.

. is a moment especially touched to the point of confusion and somewhat "panic"

People with positions are required to report on their status, while the remaining astronauts will kill time by . going to sleep.

New life in space .

After take-off, with a NASA shuttle will only take about 8.5 minutes to be put into orbit. Their maximum speed was then reached 28,000km / h. When the ship is in orbit, it is when the zero gravity environment is activated.

There will be some interesting phenomena happening now in a gravityless environment. On the one hand, body fluids tend to move upwards, so your face will be inflated like a balloon.

On the other hand, your height will be improved to 5cm while the stomach is clamped and shrunk. However, this doesn't mean much because all the people in the shuttle are so tall!

However, the accumulation of fluid in the upper body will cause constant headaches. Usually, astronauts will take a few days to completely stop the pain. Their body adjusts this amount of fluid after repeated . urination.

Almost every part of the body has problems when it comes to adapting to non-gravity environments

Besides, having no gravity will make you feel disoriented, dizzy and nauseous.

To deal with this phenomenon, the astronaut must calm down and try to help the visual system locate what is above, where is the bottom. In addition, their stomachs also need a few days to stabilize and start having an appetite.

Eating out of space inevitably leads to differences in the taste of the dishes. For example, when you eat a bar of milk chocolate you will feel like a wax.

Astronauts can't cook themselves in a space shuttle or in space stations. Their food will be cooked and specially preserved in a dry form. Whenever they want to eat, they have to add a little water and then heat it with a microwave.

One more strange experience is sleeping outside the Earth. In a zero gravity environment, you can sleep anywhere: on the floor, on the ceiling or on the wall.

Usually, astronauts use special sleeping bags, which prevent them from floating while they are asleep.

The sleeping space is quite cramped .

The ideal sleeping position on the spacecraft is next to the window. The reason is because, the first image when waking up will be the whole view of the Earth from above. In particular, from outer space, every day astronauts can see up to 16 times the sun rises.

. but every day has the opportunity to enjoy this beautiful scenery!

Meanwhile, the stern is the harshest sleeping place. The temperature here is always about 20 degrees Celsius. So, they will wear at least 4 layers of clothes, use hot food through the microwave as a heating bag before going into the sleeping bag in this area.

Back to the ground .

After completing all space missions, the astronauts will return to Earth. However, this feeling of return is not as pleasant as people think.

After landing on Earth, there will be many difficulties in moving to wait for you. First, you must try to re-establish the body balance.

Turning your head to the sides can also cause you to fall back. The muscles that have been 'asleep ' during the journey on the universe will take days, even weeks, to be able to function again. During that time, it is very difficult for you to do tasks in your daily activities.

Besides, being in the universe for too long makes the astronauts' inner ears become very sensitive. The gravity adaptation process on Earth can consume astronauts up to several days.

A trip to space always has interesting things, but there are also some problems that make it hard for you to stay for a while.

However one thing is for sure that the experiences you have in the universe will be things that you will never forget.
