According to a paper published in ENeuro, the chances for mammal brains to face “unexpected potential problems ” during space travel are high. This could hinder the plans of the humanity of exploring the space deeper. Recently a team of scientists at the University of California exposed mice to low-level radiation for six months, “severe impairments” in learning and memory has been noticed in this mouse which has made scientists anxious since it was only exposed for six months.
The results on humans under the same circumstances is unknown, but the problem seemed to be serious because lightest fluctuation in mental and physical condition could be a problem since astronauts need to respond very quickly to unexpected situations during the travel to deeper space. Going to Mars or deep space explorations are very different from traveling to low Earth orbit. Astronauts have to face galactic cosmic radiations (GCR). These are atomic nuclei from which electrons have been stripped of due to high-speed travel through the galaxy. These could pass through space crafts and skins of astronauts and possess a great threat to life. These radiations could affect different people in different ways
Thus, in a crew of five astronauts traveling to Mars, we would expect at least one member to display severe deficits in each of those cognitive functions by the time they return to Earth,” the teams write. NASA was already aware of this problem since they have funded the Brookhaven National Lab in New York to create the NASA Space Radiation Laboratory in 2003. This project is similar to Limoli’s project. The intentions of these projects are to evaluate the risks of radiation similar to that found in deep space. The fact that NASA is aware of this problem and has been trying to find a solution raises the hope of humanity.
