Swollen eyeballs, baby-like skin, and the overview effect: how astronauts feel when they return to earth | Space
Gravity may seem like clouds, but spending long periods of time without grounding strength can cause chaos on your body. On Friday, NASA and Spacex will launch the Agency’s Crew-10 mission to International Space Station To recover the astronauts Barry “Poach”, Wilmor and Sony Williams, after it was supposed to be a stay for eight days that turned into nine months.
Although this is not the most time he spent a human being as an outdoor – Oleg Kononinko and Nicolay carries the record, with 374 days – most of the tall space tasks with a maximum of six months.
So what happens to the person’s body – and the mind – on Earth?
attractiveness
Lack of gravity leads to a significant and unlike bone density loss. It also causes the muscles to be wasted between your arms, legs, trunk and other places, including your heart, which, because it does not have to pump blood against gravity, should work less difficult.
The size of your blood shrinks, and the way your blood changes – slows down in some areas, which may lead to clots. Liquids also do not decrease, or drain, easily.
“Liquids accumulate in their heads, because they feel that she has a continuous cold,” said Alan Dove, an astronomical physicist at Swinburn University. He said that the olfactory senses are also decreasing, “this is a good thing, by the way, because it wanders there,” he said, about two decades of visitors and there are no open windows.
On the positive side, when they return, they will likely feel that they have finally kicked a nine -month cold. They will also struggle to walk, get the dizziness easily, and they have bad eyesight.
He said that the accumulation of fluid also changes the shape of the eyebrows and weakens their vision. This is why astronauts often wear glasses on board, although they started an ideal vision. Duffy said this tends to return to its nature mostly, although they may need glasses for the rest of their lives.
“The brain becomes water,” said Professor and Director of Radiology at Monash University. He said that the Russian astronauts had a device, similar to a suit, which would absorb liquid and blood away from the brain.
today, space The law said that X and NASA are working on the centrifugation that can sleep the astronauts, which would get out of their heads.
When they come back, their renewal is similar to the intense physical therapy that anyone will come out of a coma.
Brad Taker, an astronomical physicist at the Australian National University, said, which can contribute to the psychological effects of return. Therefore, the doctors’ team must achieve a balance between strengthening astronauts, not their fatigue.
Duffy said their return is “the same is a research project.” This can help inform how patients are treated on the ground with conditions that involve long hospitalization – the only one without weight has many of the same effects that affected the bed. Since most research so far depends on six months residency, Wilmore and Williams will be particularly interesting for the doctors and scientists.
Duffy said that one of the truly the most surprising challenges is that because the clothes float on your skin, your skin gets “almost a child’s allergy.” Again on Earth, some astronauts feel that their clothes are sanding paper.
radiation
Perhaps the most dangerous effect of space residency in space is exposed to radiation, which may increase the risk of cancer and rare cancer. The atmosphere of the Earth and the magnetic field protects us from high levels of radiation, but in space, people do not have this protection.
“Space pioneers will not only be exposed to radiation in space more than Earth.” Nassa“But the radiation they are exposed to can pose increased risks.”
According to NASA, astronauts are exposed to three radiation sources. These include particles trapped in the Earth’s magnetic field, solar active particles of the sun, and finally cosmic rays. The National Center for Space Forexes in the field of peripheral administration and this atmosphere describes: “Slowly variable background, very active for active particles that constantly bomb the Earth” from outside our solar system, “is likely to be from explosive events like Supernova”.
How to protect people from space radiation is one of the problems that scientists try to solve while we are ready to send people to Mars or the moon for longer periods.
Taker said that astronauts do not tend to not adhere to participating in studies with mere retirement, it is not much known for how this radiation later affects life. Therefore, Williams and Wilmmore, who at the end of their career, may present a useful research in this field.
“Overview effect”
“For anyone who was cut off at the wrong airport for a day or two, and he wants to go home – imagine that you managed to see the house all the time,” Dofi said. Then look at this for nine months. “These people are really amazing in terms of their flexibility,” he said.
But when returning, Taker said that anxiety – as a result of severe conditions for a long time – and depression is common.
The husband may also test something called “the effect of general view”. Duffy said that seeing the curvature of the Earth, and seeing it from above – as a kind of its space ship, has led some astronauts to report an incredible relationship with humanity, which is an immediate feeling of fragility.
“Some people call it a sense of inspiration.” Taker said: “Some people call it insufficient feelings in terms of the size of the world.”
Then they must return to the ground, literally and metaphorically. “They have to provide breakfast and they have to lead to work,” Taker said. “It is a great transition from living in a very inspiring environment.”
