 Scientists of the University of Antwerp and the University of Liege have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting – even after 8 months back on Earth. Raphael Liegeois, soon to be the third Belgian in space, acknowledges the importance of the research, “to prepare the new generation of astronauts for longer missions.”
