WASHINGTON (AP) – He put on almost a year ago Scott Kelly's immune system and he expanded the activity of some of his genealogy compared to the two pairs of the Earth, researchers last week.
Scientists do not know if the changes were good or bad, but NASA's twin research results are unique to new questions for doctors as the spatial group aims to send people to Mars.
Testing of the genetic initiatives has always allowed scientists to find information on human biology, such as how a spinach gene generates; turning and out in a different location than at home. One remarkable change has been announced at a recent science conference: the Kelly defensive system had been simplified.
"It's like a company would have an impact on this alien environment as anything that would include you a secret fear," said Christopher Mason from Weill Cornell Medicine from New York, who helped to supervision of the survey. He said that doctors now find that in other astronauts.
From the beginning of room inspection, NASA has examined the taxation on the chambers of the astronauts, such as the loss of bones; need to exercise. They are usually in a room about six months at the same time. Kelly, who was staying at the Station Space International, spent 340 days in space and sent an U.S. table …
"I did not always have a very normal feeling in a place," Kelly said now retiring in an email to The Associated Press, announcing the usual density from her. fluid movement, headings and problems causing increased carbon dioxide weight, and exhaustion exhaustion complaints.
But this study was a specific move into the molecular level, with the company named Mark Kelly; Previously, Scott couple, on the ground for comparison. The whole results are not yet published, but researchers present some of the conclusions of a recent meeting of the American Society for Science Publishing.
Clachair has said a growing number of genes associated with the defensive system. It is not a DNA change but in the so-called "generation of generation", such as generating and generating a gene. do and enlarge or & # 39; reducing some of the crofts. Bellchair also heard a spiral in the other signal flu stream that affects the protection system. But at the same time, Kelly's blood showed fewer other types of cells that are very early anti-virus protection.
It is not surprising that gene activity changes in space – it changes as a response to all kinds of stress.
"You can see its agency responding to its environmental change," said Mason.
Good news: Most of the usual things returned shortly after Kelly got back on Earth in March 2016. These genera are connected to her; However, it seems, "he said.
"In total it is encouraging," said Craig Kundrot, who offers research on life and space science for NASA. "There are no major warning signs. We see changes that we did not expect", but we do not know if these changes are relevant.
From four Russians living in the area for over a year, NASA knew a long time from Earth, Kundrot said, "We also aim to have more than just been able. so that our astronauts can do more than just last. "
At the end, both investigations NASA's catalog of events to monitor future missions to find out if other astronomers respond in the same way. Astronauts on future missions will be able to do some of this test in space instead of frosting samples to back home scientists, Mason said.
Difficulties are really familiar with Dr. Jerry Linenger, an American steel that spent more than four months on the Spanish spy station. He said he had never been sick in an orbit, but once he had returned to the Earth "and I was probably unwell as I was in my life."
Astronauts will start on their own windows and are open to their fluid and after a week with anything else in the "extremely difficult" space station "your protective system is not really challenging, "said Linenger.
The human hope to Mars, which NASA hopes to launch in the 2030s, will take 30 months, and # 39; including time on the surface, Kundrot said.
Radiation is a big concern. The intention to bring astronauts to vibrant radiation levels would be higher than NASA's safety level. He is "just over," he said.
On Earth and even on the space station, the turf turf of magnetic fields of the Earth is from many radiators. Such a wing would not be on the way to Mars and back, but tunnels or habitats covered by rod could help Mars, Kundrot said.
Kelly, who is turning 55 the next week, saying he would go to Mars. He said a long time "worse" than I was familiar. It may be better. I think the big physical challenge, the outside radiation, will be the mission where you are in place for years. "
