Is Spending Too Much Time in Space Bad?

Do astronauts lose touch with reality after going into space? That's the question a new movie starring Natalie Portman is asking. "Lucy in the Sky" follows a female astronaut as she struggles to adjust back to life on Earth. The film is loosely based on the life of astronaut Lisa Nowak, who lashed out when her former lover began dating another woman. Nowak drove some 900 miles to confront his new girlfriend, wearing adult diapers on the ride to avoid taking bathroom breaks.
