Both NASA and the Chinese National Space Agency are only a few steps ahead putting a man back on the moon. There are already plans to build special habitats on our natural satellite, which will allow us to conduct research and extract raw materials from the Silver Globe. In the future, humanity may wish to do the same with Mars and other planets in the solar system. However, there is a problem that needs to be solved first.
Long space travel has a significant impact on the human brain
Previous studies have shown that spaceflight can cause serious changes in the human brain. This is an aspect that must be taken into account when planning a trip to space, and solving this problem may prove to be the key to success in future missions, such as planned long-term expeditions to Mars.
The most enduring brain changes associated with spaceflight so far detected is how locations in the brain called ventricles can expand by up to 25%. The ventricles are filled with cerebrospinal fluid, which helps protect, nourish, and remove waste from the brain. The lack of gravitational pull leads to the brain moving upwards in the skull and causes the ventricles to dilate.
For now, it is not even certain how long the changes in the brain will last even after returning to Earth.
It is also not known what impact this may have on human health and life expectancy. However, it has been proven that the longer an astronaut is in space, the more his brain ventricles grow. The study was conducted on astronauts who had been in space for two weeks, six months and a year.
Importantly, the researchers estimate that three years between new missions may not be enough time for an astronaut to fully recover from the effects of the previous mission.
Look: Space will be filled with dogs of different breeds. No, it’s not a joke
Look: Earth has a second moon? We explain
