Space explorations

Earth is the planet that can be occupied by human life. Outside of the earth is an empty space that consist a lot of space things such as stars, asteroid, moon, planet, etc. Also we can get a lot of knowledge by studying the space. In order to explore the space and using it for human needs, people must improve their knowledge about the universe and do some research in astronomical science about. Space exploration can give us knowledge and benefit because people can study various things such as: the beginning of universe, galaxies shapes, weather prediction, etc.

Astronomy is important for the earth and also all of organisms stay inside. That science can calculate space things movement and dynamics, can also define position that things to time. Space object like asteroid or meteor, sometimes can give us threat, because those objects often leave their orbit and than hitting the earth. It can be natural disaster in few regions of worlds but give large affect to human life.

Satellite is one of result and also tools by space explorations. Several devices has been located in above the ground, flying in gravitationless altitude. Satellite is useful for various astronomical needs, because study and research about space and also exploring the space is using astronomy. Beside that purpose, satellite development is important in weather monitoring and also earth mapping. Although consume large cost in develop one satellite and than launching it.

Satellite existence for the owner give many benefit such as : foreign object monitoring and interpolating, weather prediction, proving some universe theory, etc. The science and technology development in one country is indicate by its level in exploring the space. Sometimes space exploration product give more advantages than its building cost.
