Communication Through Satellites

Points: Communication iii the Space Age — Lie broadcasts of far-off events possible with the help of satellites — The satellites arc our platforms in the sly.

             We are now living in the Space Ag. The outer sky is already crowded with satellites launched by the different countries. They are called communication satellites because through them long-distance communications can he made. Many of them are being used for relaying radio-waves and receiving radio signals across the countries.
             Sports events in Los Angeles may be directly telecast over the TV network in India. Olympic Games and Asiad games may be viewed by spectators as if they were national or local events. What a thrill it was when the Indian viewers viewed our first man in space, Rakesh Sharma, in his space capsule. The very launching of the satellite was telecast live with the help of another communication satellite. Accurate weather forecasts are possible flow with the help of the idea-photographs sent by the satellites. But nothing matched the live pictures of the games from abroad in which India won world championship.
             The powerful television cameras fitted to the satellites are like mankind’s new pair of eyes in the outer sky. Through them we are communicating or trying to communicate with the strange, unknown world of the stars and constellations. The satellites are our platforms in sky or farthest roofs. Going over them we can see a vaster region we can communicate with much longer distances.
