Astronauts

Astronauts have to be physically and mentally ready for the stress and strain of a space mission. To prepare them astronauts are given intensive training which includes years of classroom study on technical subjects and working in a model spaceship where they can practice flight operations and become used to all the equipment on board. Apart from high intelligence, good qualifications and an excellent level of fitness, astronauts must have a stron character. They also have to be very courage in order to accept the high risks involved. Astronauts also have to face other more ordinary problems in space. What can be very annoying is the limited variety of food but the greatest challenge is getting along with other members of their team as they often come from different coutries with different backgrounds and habits. Therefore they must be very patient with each other since the lack of privacy can become irritant.
