Did you know? Behind the glamorous appearance, astronauts have experienced these embarrassing things...

When talking about astronauts, people will think of them going to the dangerous space alone, breaking through human limits one by one, completing a series of mysterious and magnificent tasks, and constantly refreshing human cognition of space. However, apart from these magnificent space missions, the lives of astronauts are actually full of various unknown embarrassing things, which are particularly interesting. Let's take a look at them today.

It's all coffee's fault

In the early days of the space age, every feeling reported by astronauts would attract great attention from scientists, because they would likely become important research clues. However, not every feeling is worth studying, and some oolong incidents are inevitable, the most typical of which is the space headache incident.

At that time, some astronauts reported experiencing mysterious headaches in space. In order to maximize the safety of astronauts in space, people invested a lot of resources in research.

Is it a change in intracranial pressure? Or a lack of oxygen in the cabin? None of them. The final answer is: caffeine withdrawal symptoms. These astronauts usually like to drink coffee, and they did not forget it even in space. However, these coffees were cooled and dried before being sent into space. This process greatly reduced the caffeine content in the coffee. Therefore, these scary headaches are actually just symptoms of caffeine withdrawal.

Chaos Maker

In order to facilitate the astronauts to move freely in the cabin, there are handrails throughout the International Space Station for astronauts to use for support. However, it is not easy for a novice astronaut to use these handrails gracefully to swim in mid-air. They often need to spend a certain amount of time and energy to learn and adapt, and sometimes it will cause confusion.

One astronaut said that when he tried to fly from one module to another for the first time, he caused a mess because of his over-aggressive movements: behind him, a bunch of scientific research equipment that was not adequately fixed all floated up and "flew freely" in the air, which scared him into a cold sweat. "When you first arrive, you are like a bull in a china shop, clumsy and awkward," he said.

Happy Moon Face

With the advent of the space economy era, space travel is getting closer and closer to us. However, in the early days of space travel, it may not be very friendly to people with high appearance and love of selfies.

The weightless environment will disrupt the uniformity of blood circulation in the body, causing the blood pressure in the head to exceed the standard. In the first few hours of arriving in space, your face will become what astronauts call "moon face", and it is estimated that the selfie at this time will hardly exist in the camera for more than one second.

Midnight Horror

Human beings’ exploration of space is always accompanied by various shocks, including not only external shocks but also shocks to oneself.

When they first enter space, astronauts have not yet fully adapted to the series of abnormal phenomena brought about by weightlessness. For example, when you fall asleep, as your body relaxes, your arms will float up instead of staying at both sides of your body.

Astronaut Vance Brand foolishly forgot this and gave himself a fright, choosing to sleep with a clip to the armrest while the other astronauts strapped themselves into their sleeping bags.

Waking up in the middle of the night, Brand was terrified to see something floating in front of him - yes, it was his own two hands.

Leaking space suit

If we rank all the embarrassing things, the most embarrassing one would be the space suit urine leakage incident.

In the early days of manned space flight, male astronauts often complained that their urine leaked into other parts of their space suits. Researchers repeatedly checked the entire catheter line and the tightness of the space suit, but after a long time of research, they could not find the problem.

The problem is not the technology, but the "vanity" of men - the culprit of urine leakage is that the size of the condom catheter used by the astronauts is too large. It turns out that whenever the doctor asks the male astronauts what size condom catheter they need, driven by male vanity, they usually say "large"!

After learning the whole story, NASA experts acted decisively and changed the sizes of astronauts' urinary catheters from large, medium and small to large, extra large and giant, which greatly improved the "urinary leakage" problem.

Space diapers

However, what really solves this problem fundamentally is diapers. After all, there is no value in exaggerating the size of these things.

Humanoid Godzilla

In addition to the various embarrassing things that happen when entering space, astronauts who have lived in space for a long time will also encounter various ridiculous problems after returning to Earth.

The most intuitive manifestation of the embarrassing incident on the return journey may be the weakening of the human body's ability to move.

The weightless environment in space will cause the bones and muscles of astronauts to gradually atrophy, so those astronauts who live on the space station have to exercise every day. But even so, when they return to Earth, their athletic ability will still deteriorate visibly.

In this regard, Canadian astronaut Chris Hadfield once recalled that in the first week after he returned to Earth, he could only move laboriously and slowly, like Godzilla moving clumsily on land. It was not until four months later that he could run normally.

Cup Throwing Master

After returning to Earth after a long stay in space, it is difficult for astronauts to quickly change many of their behaviors, and this often requires them to pay a certain economic price.

Many astronauts have had this experience: after returning from a long stay in space, they often become "cup-smashing masters" at home - they think that these things will still stay in place as they were in the space station as long as they let go.

Sometimes, when they throw something at someone else, they don't realize until they see it fall to the ground that this is no longer a space station and they need to use more strength to throw it in a parabola.

Because we always forget the existence of gravity, various small objects such as plates, cups, remote controls, etc. have all become "victims".
