Space tourism|Being in space weakens data processing, found in the study. The six -month command at the international space station was enough.
The abstract is made by artificial intelligence and checked by man.
Being in space reduces the processing and working memory of astronauts.
The six -month command on ISS slowed down astronaut performance.
The results are important in the design of possible Mars flights.
Space Strange conditions such as small gravity, intense radiation and lack of light variation in light can strongly affect the physical health of astronauts. They lose muscle in space, and the risk of heart disease increases.
The effect of staying in space on mental abilities has been less researched, although it may play a major role in traveling. Space pilots must be able to be able to make complicated tasks where even small mistakes can have fatal consequences.
In the new The study revealed that the six -month command at the international space station slowed down the processing of astronauts and impaired working memory and concentration. In addition, risk -taking was reduced.
Risks are on a space trip in many situations necessary to perform and survive tasks.
Nasan The researchers measured 25 Astronaut intellectual performance by ten test radiators first before departure, then twice in space and twice more returning to the ground.
Astronauts had to make, among other things, a pattern decision and try to fill the balloon at the optimal point where it is at its lighter but does not explode.
The researchers found that astronauts performed tasks at a space station more slowly than on the ground, but otherwise did one accurate result. The effect of sleep deprivation and stress levels were ruled out.
Even after returning home, data processing and working memory work more slowly than before a space trip. One month after the trip, the working memory had still not returned.
Study Published by Frontiers in Physiology.
In the past In studies, astronauts themselves have reported brain fog. In addition, changes have been observed in the structure and function of the brain.
In their report, researchers emphasize that they did not detect systematic and widespread deterioration in intellectual performance, which would indicate the damage to the central nervous system during space. The ERP of the tested astronauts remained stable.
The information is important when weighing a year -long space flight to Mars.
Not only does the journey take much longer than any space trip made so far. On the flight, the crew must also be able to fully independent decision -making and problem solving. The country cannot be helped due to the length of the distance, says Elisa Raffaella Ferrè For New Scientist.
“Human performance plays a key role. Astronauts with a slow reaction time cannot be sent to Mars. ”
