Astronauts can not do anything in space

We usually give less importance to some common daily tasks and actions on Earth, like enjoying a loaf of bread with butter or taking a hot shower, but the astronauts of the International Space Station (ISS) end up Finding ourselves realizing how much these things are looked down on by us, at most, we have already traveled by plane into the atmosphere of the planet and we have never had the opportunity to do so. Experience of the absence of gravity

These astronauts face, in addition to the dangers of space travel, microgravity as an obstacle to the performance of daily tasks. Basic habits, such as eating and sleeping, also require adjustments and sacrifices. So here are some things of our everyday life that astronauts simply can not do in the same way in space:

Cry

In the space, tears do not fall on people's faces. After all, it takes gravity. So, if an astronaut starts crying for homesickness, a liquid "ball" of tears forms in his eyes, which interferes with the person's eyes until the ball becomes big enough to fit itself. off.

Taking a Hot Bath

All space resources should be used in the most efficient way possible. So, you can not waste water in any way. Instead of showers (which would be useless because gravity has to bring down the water), astronauts take sponge baths with distilled water from the humidity of the water. Air, urine, oral hygiene and washing.

Indeed: the bath water is reused for other activities. At ISS, water is collected in the air humidity and in human waste to be transformed into purified drinking water. And since there is no effective way to wash clothes, astronauts wear the same clothes on a daily basis, without washing at all.

Savouring Food

the mouth is affected after a period of stay. And on their return to Earth, astronauts said the food had a more intense taste than before. This is because in space, body fluids move differently because of the absence of gravity, so that the fluids eventually reach the head and can fill the nasal pbadages. At least, this is a possibility, while the strong smells in the ISS cabin affect the sense of smell, which influences the taste.

No bread, soda or salt [19659014]

ISS astronauts can not eat a good buttered bread at breakfast. Bread can release crumbs that, floating during the season, can damage equipment or be accidentally inhaled by astronauts.

Regarding soft drinks, Vickie Kloeris, NASA, explains that "soft drinks are not shipped [à ISS] because gasification and refrigerant do not separate into refrigerants." Microgravity ", the drink does not not floating in an environment without weight.

Powdered condiments, such as salt and pepper, are prohibited for the same reasons as bread crumbs, which can damage equipment or enter through the mouth, ears and nose of astronauts.

Write with ordinary pens

The ink of the pen needs the action of gravity to go down to the top (and if you already have tried to write with an ordinary pen back knows it). Thus, to write the pen in space, astronauts need a special pen, whose cartridge is pressurized with nitrogen. This pressure pushes the ink towards the tip and this pen can be used upside down, in the space, at extreme temperatures and even under water. Here on Earth, we can (if we want or need to) coordinate the hours of sleep with sunrise and sunset.

Sleeping on the right

of the Sun. In space, this is not possible. As the ISS rotates around the Earth at an average speed of 27,700 km / h, completing 15.77 orbits a day, astronauts can observe about 15 sunsets in as little as 24 hours.

sleep simply can not depend on light patterns.

Drinking alcohol

Alcoholic beverages are now banned at the # 39, ISS. In 1972, it was proposed to bring sherry to astronauts, but the outrage of the public was louder and the astronauts missed the opportunity to know what it was to live the hangover in space . Years earlier, in 1969, it had been said that Buzz Aldrin had even celebrated his landing on the moon with a dose of wine – but that was not part of the show and some people think that he only one legend.

According to the BBC, Russian cosmonauts could consume cognac in a moderate way to improve their immune health.

Sex

If you were delighted with one of the first scenes of the series The Expanse which shows a couple having bad in microgravity, can take the horse out of the rain because badual acts are forbidden in the ISS. And even if two astronauts were at risk of having bad violating the rules of the station, it would be quite difficult to go unnoticed, because there are rare moments of privacy and astronauts face an intense daily workload. – which means

Defecating in space is a strange and disastrous moment, but also embarrbading. Obviously, there is no toilet on the ISS and the cabin designed for this purpose has no door (only a curtain). So yes, you can hear your colleague doing the "number 2". And not to float as long as they are there, at this moment of concentration, astronauts still have to attach to the structure.

In addition to not being very easy to hit the "target", which is smaller and smaller than a common sanitary seat, lack of gravity can lead to uncomfortable complications, leaks that may eventually occur in the collection container, with fecal matter floating on the ISS.
