Abstract

This study investigated the effect of spaceflight on time perception. Ten astronauts were tested before, during, and after a 6–8-month spaceflight. Results showed a relative overestimation of 1-minute intervals during flight and a relative underestimation of intervals of hours. However, estimations of days since events like vehicle docking and spacewalks were accurate. Altered time perception might impact time-critical operations.
