The Sputnik‚ the world’s first artificial satellite‚ was launched by the Soviet Union and sparked a change in history that would greatly alter two already feuding places - the USA and the USSR. The “Space Age” or “Space Race” was a race between Russia and the United States for the supremacy of outer space. The Sputnik satellite led to additional funding for the space program in the United States‚ and the formation of the National Aeronautics and Space Administration (NASA). The creation of the Sputnik

HSC PHYSICS: SPACE * 1. “The Earth has a gravitational field that exerts a force on objects both on and around it.” Students learn to “define weight as the force on an object due to a gravitational field.” Mass is the amount of matter in a body whereas weight is the force due to gravity acting on a mass. Mass will not change where the acceleration due to gravity is different but the weight will change. For example‚ bathroom weights are calibrated in kg‚ but actually measure

positioning of the receivers in deserts so that there is no interference in transmission and the main role of rectenna in conversion of energy is studied. This study discusses about the main technical challenge that is the construction of power satellites that uses electrical thrusters instead of chemical propulsion to move in the geosynchronous earth orbit‚ thus decreasing the total weight of the system by 67% and thus making it a low cost ecofriendly launch vehicle.

United States of America‚ Russia‚ Great Britain‚ France‚ Japan and China were the other members. Since then there is no looking bad. India’s space research was born on the VSSC campus.

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
