When they are in space, astronauts suffer the Charlie Brown effect or Puffy Head Bird Legs syndrome. Those who suffer from this syndrome have their faces swollen and their legs get thinner. In addition to this it can lead to foggy vision, due to high pressure. Furthermore, the Blackout symptom could appear, and this could put astronauts in great danger. Researcher Damian Bailey, professor of psychology and biochemistry at University of South Whales, after a study, he explained that some parts of the brain receive too much blood in low gravity conditions. This way the arteries conduct blood to the brain relax and they open too much. Because of that, the brain is overwhelmed and the edema appears – the accumulation of water in the tissue, which leads to its expansion, and the oxygen cannot travel to certain parts of the brain fast enough. That’s why astronauts often experience problems with their cognitive skills when they’re in space. To understand better the problem we’re confronting, we went through multiple stages. First of all, we started an individual study on the Internet and we identified multiple problems, from which we selected one that was more important. We then visited the neuropsychology lab at the Biology College, where we tested equipments of electroencefalogram and neurobiofeedback. Iulia: We participated at the “Steps into Space”, held at the Atheny, where Bogdan Marcu, propulsion engineer, ex-coworker at SpaceX and Rocketdyne has presented to us aspects about space exploration.
