This may remind you of the interstellar movie, but wait that it is not fictional! Yes, astronauts age slowly when they are in space.
When Sunni Williams and Bari Butch “Willmor are preparing to return to the ground after their long stay in space, all concerned with how their gravity will welcome them. Both astronauts live in micrographery over the last nine months, and sudden effects of gravity can affect their health.
Astronauts at space stations age age a little slower than the rest of us. The European Space Agency said this in the post on X.
How gravity land will act on Sanit Williams and Barry Wilmora’s health after returning to the ground
A famous NASA twin study shed more light on how the human body responds to space. For the study of the NASA twins compared the retired astronaut Scott Kelly when he was in space, with his equal brother -in -law, retired astronaut Mark Keli, who remained on the ground.
NASA found that the cattle left in space survived the change of length; Telamers protect our chromosomes and usually become shorter as we age. Scott had some changes in the expression of genes that changed after returning to the ground, but a small subgroup remained six months later.
“Cognitive characteristics of Scott (for example, mental vigilance, spatial orientation, emotions) remained largely unchanged during their time in space and regarding the land. This is important, because it suggests that astronauts can support high levels of cognitive. Keep for longer duration.
“Its bone cleavage and bone reform cycle occurred at a faster rate during the first six months, which he was in space, but slowed down in the second half when his exercise volume was lower,” NASA discovered.
In space, astronauts feel the thickening of the carotid artery, which is any of the two large pipes in the neck (arteries) that carry blood into the head. Space flight conditions can increase oxidative stress and inflammatory reaction, which will lead to dysfunction of the endothelium of the vessels and structural changes in the arteries that return to the level of the previous light.
“By detecting a carotid artery using ultrasound and blood and urine choice, researchers found signs of inflammation and thickening of the carotid walls into Scott during and immediately after its mission,” NASA said.
“NASA recognizes the twins study as the first study of its Kind to compare Molecular Profiles of Identical Twin Astronauts, and a Methodology to Integrate Research from the Teams Was Establisted. Share The Same Genetic Makeup, Twin Studies Provide A Way For Scientists To Explore How Our Health is Impacted by The Environment Around us, Independent of the Faceical Variations that Naturally Occur Between Most Individuals, “NASA had said about this study.
In microgravity, the absence of gravitational force leads to a decrease in muscle use, which leads to muscle atrophy. Astronauts can experience up to 20% of muscle loss during missions that lasted five to eleven days. This decrease in muscle strength causes problems after returning to the gravity of the earth, which affects the posture and movement.
Space flight has long been associated with visual acuity problems such as visual swelling and smoothing the globe. These changes are associated with high intracranial pressure in microgravity, which potentially leads to long -term vision problems.
In the sterile environment ISS may lack the useful germs necessary for a healthy immune system. This absence can lead to impaired immunity regulation, making astronauts more sensitive to infections and allergic reactions when returning.
What medical tests do astronauts after returning to the ground?
X -ray absorption absorption (DEXA) scanned the measurement of bone mineral density to detect bone loss as a result of prolonged weightlessness.
Muscle strength and endurance assessment determine atrophy and functional disorders with a decrease in muscle use in microgravity.
Echocardiograms and MRI evaluate the structure and function of the heart, monitoring such as heart atrophy or altered function.
Evaluation of postural stability reveal disorders in equilibrium and coordination from the adaptation of the vestibular system in microgravity.
Eye traffic tests determine neuro-visual syndrome associated with space light (Sans), which can affect vision.
Memory assessments, attention and executive function reveal the cognitive changes that result from expanded space missions.
When does Sunnite Williams return to the ground?
Sunni Williams and Butch Wilmore are expected to return on March 19 or 20. As of December 2024, plans were created for Williams and Wilmore to return to the ground no earlier than at the end of 2025 on the new Dragon SpaceX capsule.
