Introduction

Space is defined as the region of our environment outside the earth’s crust. It consists of three different regions called the troposphere, the stratosphere and the ionosphere. Man had always been curious to discover what actually lies out there in space. It is the need to find out what exists there in outer space that led man to begin the activities of space exploration through space travel.

Space travel means to make a journey far beyond the earth’s atmosphere into outer space. Space travel by man started on October 4, 1957 when a rocket driven Russian space craft called Sputnik carried men into space. Ever since, the Americans have been more successful in space travels than all other nations. They had successfully conducted several space travels with their Apollo space vehicles. Apollo II was the first to land men safely on the moon.

There are many reasons for which scientists travel to outer space. Some of them are:

1. For the acquisition of knowledge
2. To boost national prestige
3. To show military might
4. To find out if there is life on the moon and other planets
5. To colonize other planets
6. To help scientists find out the type of weather conditions that exist in outer space and on other planets. The idea is to find out the possibility of dwelling in such places
7. To provide a base for various activities in outer space
8. To provide such nations with a base for certain scientific and military activities that cannot be assessed by other nations
