the political competition between U.S.A and the U.S.S.R.‚ where the two nations invested highly on technologies to see who could win the space-race. Artificial satellites‚ a man made device that orbits around Earth or other planets‚ came along at about 1951‚ when the Russians launched "Sputnik 1" into orbit around Earth. Since then‚ satellites have developed technologically and now they are so widely used‚ that almost everyone’s benefiting from them in everyday life. Through space exploration‚ a lot

Assembly assumed responsibility for all outer space matters and discharged it primarily through its Committee on the Peaceful Uses of Outer Space (COPUOS). It was established in 1958‚ shortly after the launch of Sputnik‚ the first artificial satellite to be put into outer space by the Soviet Union‚ as an ad hoc committee. In 1959 it was formally established by United Nations resolution 1472 (XIV). At that time the Committee had 24 members. Since then it has grown to 69 members and is one of

better late than never. The beginning was made in 1975‚ when India launched its first scientific satellite Aryabhatta I into space‚ in collaboration with the U. S. S. R. As we did not have our own rocket-launcher‚ we were helped by the Russians. However‚ it gave the country space status. The second satellite‚ Bhaskara I‚ was launched on 7th June‚ 1979 from a Soviet commodore. This 444 kg experimental satellite contained instruments for carrying out remote sensing experiments. Then an improved version

Although the exact date of when rockets were first invented is still unclear‚ it is believed that the Chinese invented the first “rocket” (“The History of Rocket Science”). Moreover‚ the Chinese used gunpowder‚ invented in around 100 A.D‚ and positioned it in Bamboo sticks for religious festival tradition (“The History of Rocket Science”). Large bamboo sticks were created and decorated by Monks and villagers‚ then blasted skyward to inform the Rain God Phaya Thaen that it is time to send rain down
