We usually do not give as much value to some of the common daily tasks and actions on Earth, such as sipping a piece of sandwich or taking a hot shower, but astronauts at the International Space Station (ISS) our own skin, how much these things are despised by us, that we at most already flew in the atmosphere of the planet and never had the opportunity to experience gravity.
These astronauts stand in addition to the dangers of space travel, microgravity as an obstacle to performing everyday tasks. Basic habits such as eating and sleeping also require adaptations and sacrifices. So below you can check out some of our everyday things that astronauts simply can't do in the same way in space:
In the room, tears do not fall on people's faces. It takes gravity for it. So, if an astronaut starts crying for homelessness, a liquid "tower ball" is formed in the eyes, tormenting the person's eyes until the ball becomes large enough to loosen. This ball of tears, when released, ends up flowing within the ISS.
Take a hot shower
Any resource in space must be used in the most efficient way. So you can't waste water in any way. Instead of showers (which would in any way be useless as gravity draws water down), astronauts take baths of water distilled from humidity, urine, oral hygiene and wash hands.
That's right: bath water is recycled from other activities. At ISS, water is collected from moisture in the air and from human waste to be converted into purified drinking water. And since there is no effective way to wash clothes, the astronauts immediately wear clothes on a daily basis, not even wash.
In the room, the palate is affected after a residence time. And when they return to the ground, astronauts said that food tastes more intense than before. It is that in the room the body fluids move differently due to gravity, so liquids end up in the head and can fill the nasal passages. At least it is an option, while the other is that the strong odors in the ISS cabin affect the sense of smell, which in turn affects the taste.
No bread, soda and salt
ISS astronauts cannot eat a good butter bread for breakfast. Bread can release crumbs that flow through the season, damage equipment or accidentally inhaled by astronauts. Since the 1980s, NASA has replaced tortillas with tortillas in this case.
As for soft drinks, Vickie Kloeris from NASA explains that "carbonated beverages are not shipped [à ISS] because carbon dioxide and refrigerant are not separated into microgravity, where the beverage does not flow in a weightless environment.
Powdered spices, such as salt and pepper, are banned for the same reasons as bread crumbs which can damage equipment or enter the astronauts' mouth, ears and nose. Liquid versions of these spices are provided by NASA – after all, "astronaut food" must also be hot.
Writing with ordinary pens
Pretty ink requires gravity to go down to the tip (and if you've ever tried writing with a plain upside-down pen, you know). So, to write the pen in the room, the astronauts need a special pen whose cartridge is pressed with nitrogen. This pressure pushes the ink toward the tip, and this pen can be used upside down, in the room, in extreme temperatures and even underwater. Another option is to hand over the pen and adopt the good old pen.
Here on Earth we can (if we want or need) to coordinate sleep plans with sunrise and sunset. In the room it is not possible. As the ISS orbits the earth at an average speed of 27,700 km / h and performs 15.77 lanes a day, astronauts can experience about 15 sunsets in as little as 24 hours.
Thus, your sleep plans simply cannot depend on light patterns. So part of the astronaut training before going to the ISS rightly includes the ability to fall asleep and wake up, whether day or night.
Alcoholic beverages today are prohibited on the ISS. In 1972, it was suggested to bring sherry to the astronauts, but the public disgrace spoke louder, and the astronauts missed the chance to know what it was like to experience hangover in the room. Years earlier, in 1969, they say Buzz Aldrin himself celebrated landing on the moon with a dose of wine – but it was not part of the broadcast and therefore some believe it is just a legend.
But according to the BBC, Russian cosmonauts can consume cognac moderately to improve their immune system.
If you were happy with one of the first scenes in the series The Expanseshowing a couple who have sex in microgravity can take the horse out of the rain because sexual acts are prohibited in the ISS. And although a couple of astronauts risked having sex that breaks the station's rules, it would be pretty hard to go unnoticed as there are rare moments of privacy there and the astronauts are dealing with intense daily workloads – which means some time for something fun .
Make "Number 2"
Defecating in the room is a peculiar and disastrous moment, as well as embarrassing. There are of course no toilets on the ISS, and the cabin designed for this purpose has no doors (only one curtain). So yes, you can hear your colleague make "number 2". And not to float while they are in that moment of concentration, astronauts still have to bind to the structure.
In addition to being very easy to hit the "target" which is smaller and smaller than a common sanitary napkin, the lack of gravity can cause some, say, unpleasant complications, as any leakage from the collection container can occur with the stool swims by the ISS. Yuck!
