Space travel or journey to the moon is so more a dream. It is possible for man to travel into outer space in a spaceship over thousands of miles. It is now possible for him to travel to the moon. Space travel became.Possible when the Russians started sending artificial satellites into outer space in 1957. These satellites travelled around the earth hundreds of miles about it. Afterwards the Americans sent their satellites into ouster space and reached the moon in 1969.

Spaceman or astronauts have to face difficulties and dangers. For example, they have to breathe oxygen, as there is no air in outer space. They have to face the problem of weightlessness in space when they are out of the gravitational pull of the earth. They are trained well to face it. Extremely dangerous rays like cosmic rays and solar rays all the time attack the spaceship.

Space travel is of great benefit. It has made visits to moon possible. It may make it possible for man to travel to other planets like Mars. Spaceman collect a lot of useful information about space while travelling through it. They have special instruments on their spaceship to record facts about the different kinds of rays or radiations, electric charges, etc .present in space.
