A. People have always dreamt about space travel and space discoveries. For the first time the dream came true when the unmanned satellite Sputnik was launched and scientists got the first photos of the Earth from outer space. However, the real breakthrough happened in 1961 when the first human, Yuri Gagarin, left our planet on the spacecraft Vostok and completed a full Earth orbit.

B. Since then lots of people have volunteered for space missions but few are able to meet the strict requirements for candidates. Still on the Earth, the future astronauts do tests in simulated environments and solve problems they are supposed to face during the flight. They get ready physically and psychologically for different situations. They also practise how to operate the complicated space equipment and what to do in an emergency.

C. Even wearing a spacesuit requires special skills. The main idea of the suit is to keep the person alive in outer space, during launch and landing, when the pressure on the body increases dramatically, or inside the space station, if something goes wrong. The suit is made from hard materials, contains its own oxygen supply and has lots of smart devices monitoring the condition of the astronaut.

D. Obviously, no device can completely eliminate the risk of space travel - it will always be a dangerous activity, but it attracts people anyway. They are ready to pay big money for an out-of-this-world experience and the number of such people is constantly increasing. There are already business projects for space tours and designs for space stations stuffed with equipment for entertainment instead of scientific experiments.

E. Not everyone supports the idea of idle space tourists, and there are reasons for this. Apart from unnecessary risk, it can add to the problem of space pollution. People have only started going into orbit very recently but they have already managed to leave lots of evidence of their existence there - parts of old spacecraft and satellites are circling the Earth. Scientists say that if this increases, it may cause serious problems and dangerous situations.

F. Nowadays, countries find it useful to combine their efforts when carrying out space exploration projects. The best engineers from all over the world participate in designing crafts and equipment, and astronauts working on the space station may be of different nationalities and backgrounds. Theoretically speaking, it might cause some misunderstanding and culture clashes, but in practice this never happens.

G. Long space missions, however, are going to be a great challenge to the flight team whatever nationality they are. The astronauts will have to communicate only with each other and there will be no opportunity to escape unpleasant people. Psychologists believe that stress is a serious risk factor for the planned expedition to Mars.
