Nine months in space can lead to a permanent change of the body, leaving the astronauts Sonita Williams and Barry Wilmur with possible long -term health effects.
It was a task that lasted much longer than the scheme.
US astronauts, Sonita “Sony” Williams and Barry “Poach”, went to space on the plane at Boeing Starlener Calipsu on June 5, 2024. They were supposed to spend eight days at the International Space Station (ISS).
But as the spacecraft approached the station, the defenses were disrupted, and NASA ordered astronauts to stay on the International Space Station while knowing how to return them.
That lasted nine months, or 288 daysWilliams and Wilmmore made two of the tallest NASA astronauts in space in one mission.
Who spent the longest time in space?
ISS events take place at an altitude of 354 km (220 miles), while the average distance to Mars of the Earth is 225 million km (140 million miles).
Astronaut Frank Rubio holds the record for the longest space mission in NASA, where he spent more than a year on the International Space Station.
The total registry of individual space light belongs to the Russian Valeri Polyakov, which spent 437 days on the Mir Space Station.
When did the Spacex Crew-9 mission return to Earth?
the Spacex Dragon The spacecraft that carried Williams and Wilmore to Earth at approximately 5.57 pm local time (21:57 GMT) fell off the coast of Florida, after it was neglected from ISS at 05:05 GMT.
On board with Willmore and Williams, Rossiusus’s novel was for astronauts in Russia Alexander Gorbonov.
NASA provided live coverage of the honor to Splashdown.
Now again on the floor, the crew will have to adapt to the return on the floor, physically and mentally.
How to live in space in the body?
Spending months in precise gravity brutal on the body. Without pulling gravity to the earth, the muscles shrink, the bones weaken and the physical fluids turn.
Space pioneers quickly lose muscle mass because they do not use their legs to support their weight. Their bones become fragile and lose 1 percent of the bone mass per month – equivalent to a whole year of aging on the ground.
Radiation is another great concern. Although ISS is protected by the Earth’s magnetic, the astronauts in the six -month or more missions are more than 10 times the radiation, which occurs naturally on Earth. The prolonged exposure is associated with higher risks of cancer and a possible cognitive decrease.
- Body mass and fluids: Space pioneers lose about 20 percent of body fluids and about 5 percent of the body mass while they are in space.
- Muscle: Minor gravity causes muscle atrophy, but exercise for two hours a day, six days a week, and nutritional supplements can reduce muscle loss.
- leather: The skin and tears whisk easily and slowly heal in space.
- eyes: Microorganism weakens the vision while the radiation increases the risk of cataracts.
- DNA: Most genes are resets after returning to Earth, but about 7 percent remain a disruption.
- Psychological and perception: Radiation may cause brain damage and the beginning of Alzheimer’s disease. The space disrupts the trend, causing movement disease.
- Cardiovascular system: The blood circulation slows down and decreases the production of red blood cells. Errotection is common.
- The immune system: The immune system weakens. Six -month radiation exposure is 10 times the annual exposure on Earth.
- Bones: The skeleton deformation and bone loss with the loss of the bone mass 1 percent every month. Space pioneers become longer because their thorns expand while they are in orbit.
How does the body recover on the ground?
Return to Earth does not immediately back down from pressure on the bodies of astronauts. With their bodies modified to gravity, they suffer from balance problems, dizziness and weak cardiovascular function.
Even after months of landing, everything is not recovered. They face long -term health risks, including cancer, nerve damage and degenerative diseases.
- Access from space: The spine returns to the normal size. Puffer is no longer a problem, and blood pressure is normalized.
- After one week: Movement, confusion and balance disappear. Sleep returns to normal.
- After two weeks: The immune system recovers, and lost body fluids are restored. The production of red blood cells is due to normal.
- After one month: The muscle repair is almost complete and near the pre -trip levels.
- Three months later: Full redevelopment of the skin. The body mass dates back to Earth levels, and vision problems are no longer present.
- Six months later: The risk of bone fractures as well as increased risk of cancer remains. Ninety -three percent of genes dates back to normal, but 7 percent are still disrupted.
