American identical twin astronauts Scott and Mark Kelly took part in a special project of NASA. In this context, Scott Kelly, one of the identical twins, was launched into space for a year. Mark was appointed to a 1-year mission on Earth.
Scott, who was sent to space, departed from Earth to the International Space Station on March 27, 2015 and returned exactly 1 year later.
After returning to the planet, researchers examined differences in the twins’ health and biology, covering just about everything from cognitive function to gut bacteria.
According to the report from NASA, ‘one of the most striking discoveries’ of the research was that Scott’s telomeres (caps at the end of chromosomes) were longer than Mark’s while in space. However, when returned to Earth, they quickly returned to their normal length.
This was apparently the ‘exact opposite’ of what scientists had predicted, as shorter telomeres are often linked to ‘aging’.
NASA researchers also found that men had different gut bacteria throughout the study, although this may be due to different diets and different environments experienced.
On the other hand, it was found that Scott’s white blood cells decreased, while Mark’s white blood cells increased.
According to NASA, “These results may point to genes that are more sensitive to the changing environment, whether on Earth or in space.”
COGNITIVE PERFORMANCE
Researchers find differences in Scott and Mark He found more than 200 thousand RNA molecules. This means scientists are taking a closer look at whether a space gene was activated while Scott was in space.
When it came to cognition, Scott’s performance was largely unchanged and better than Mark. While this may not sound like a significant discovery, NASA scientists have led astronauts ton ‘they can maintain high levels of cognitive performance for longer periods of time in space’ It was said that it was useful because it suggested it.
CAN THEY GO TO MARS?
Speaking to space.com about the experiment, Scott said:
“As a result, as a result of all these studies, nothing was found that would prevent us from going to Mars. Of course, there are many issues that will continue to be studied, such as genes and telomeres, but there is nothing risky that catches the eyes of experts.”
