The Satellites play a very important role and it is due to these satellites that technology is getting so vast, high, and much much greater, which is making the life of human so easy and relaxed. The moment we switch on our mobile phones our location can be tracked immediately by Global positioning system, due to the satellites revolving around the earth. The whole earth can be covered by just 3 Geo-stationary satellites. The largest satellite system is managed by 126 countries.
In 1984, at a height of 100km above the Hawaii Island with a speed of 29000km/h, Bruce McCandless stepped into space from a space shuttle and became the first Human satellite of the earth.
