Extended Space Missions Could Permanently Change The Brain Structure

Before astronauts embark on a mission to Mars, it is imperative for scientists to know everything they can about the impact of long term space travel on the human body. Previous studies have shown that extended exposure to microgravity causes muscles and bones to weaken, deteriorates vision, and, in some cases, even alters the astronaut’s DNA. Now, there is evidence that spending a long time in space could also permanently change the brain’s structure.
