Four candidates to become astronauts in the Hungarian to Orbit (HUNOR) programme have successfully completed a six-day isolation training session, HUNOR said on Facebook on Friday. During the training, the four candidates were placed in isolation in a 48-square-metre container with conditions similar to the International Space Station. They had to undertake simulated tasks like the ones they would in space, such as conducting experiments, while carrying on with everyday routines. The simulation also included emergency situations that required split-second decisions. The candidates’ mental states and response to lack of sleep and stress situations were gauged during the training session.
