CNN —Spaceflights lasting six months or longer take a toll on the brains of astronauts, and crew members may need to wait at least three years before returning to space, according to new research.
Scientists compared the brain scans of 30 astronauts taken before spaceflights lasting two weeks, six months or a year with scans taken after they returned to Earth.
During the analysis, the researchers determined that the degree to which the ventricles enlarged varied depending on how long the astronauts were in space.
Seven of the astronauts with a shorter period of recovery between missions showed little ventricular enlargement after their most recent flight.
However, astronauts have very specialized skill sets and training and there may be rationale to include them on additional missions before this time.”
