Like television, our mobile phones, internet and all, the information about earth and space we get from artificial satellites. Do you know the first artificial satellite was SPUTNIK-1 launched by Russia? NASA and ISRO have send many satellites to space till date.
ISRO was the first one to send the satellite ‘Mangalyan’ to Mars.
Next time , whenever I use television or mobile phones I am surely going to think about the benefits of satellite. What about you?
