India is a major force in space research. In 1975, India launched its first satellite named Aryabhatta. A few years later, our country sent two remote sensing satellites into orbit- Bhaskara I and II in 1979 and 1981 respectively. These satellites were launched to observe the Earth.
In 1979, India launched a series of satellites named Rohini. Rohini helped our scientists to understand the technology behind the functioning of larger rockets better. Later, India developed its first satellite launch vehicle- SLV 3. On July 18, 1980, SLV 3 made its first launch- the launch of satellite Rohini that weighed 40 kilograms. After SLV 3, India successfully developed PSLV and GSLV.
