The working schedules are extremely heavy in space as they remain in touch with the earth centers with the video connections and astronauts have a little time to enjoy their private time. The situation is very tense in space strong mental health is needed there.
In a near future, doctors would be able to look into an astronaut space life through portable brain scanner. This could be highly helpful in examining the mental health of the astronauts. This device would provide information and help in monitoring the astronauts for signs of any kind of brain injury or depression or mental tiredness.
In these conditions the astronauts would loose their ability to make critical repair work of space equipment.This scanner is not finally released. The research work is going on at Massachusetts General Hospital in US state of Boston. This will be finally evaluated for its performance and safety perspectives. After then it will be handed over to NASA which will think to send it into orbit.
