My brain in space.

Human space flight presents many behavioral challenges associated with working in an extreme harsh environment. Concerns about alterations in cognitive function have led to a series of experiments to assess human performance in space and to develop strategies for assisting crew working in these mission critical environments. Day-night cycles every 45 minutes may affect circadian rhythms and the absence of gravity can result in disorientation particularly during space walks. Understanding these adaptations is of importance in preparing for future missions to the Moon and Mars.
