Astronauts returning to Earth after a long stint in space are so badly disorientated that they usually can’t walk properly for 24 hours or longer. Turns out human brains function differently in space and when an astronaut gets back, it takes his or her brain some time to re-train itself. Now Marissa Rosenberg, a neuroscientist at Nasa, plans to use virtual reality headsets as a tool to short-cut the training.
