Explanations:The Indian Space Research Organisation (ISRO) has a rich history in space exploration and satellite launches. One of the significant milestones in this history is the launch of the Rohini satellite in 1980. This satellite was launched using the Satellite Launch Vehicle (SLV-3), which was the first indigenously developed launch vehicle by ISRO. The launch of Rohini was a crucial step in establishing India's independent space capabilities and marked the beginning of a series of successful satellite launches by the country.
It is important to distinguish between the first satellite built by India and the first satellite launched by India. While Aryabhata was the first satellite built by India, it was launched by the Soviet Union in 1975. The Rohini satellite, on the other hand, was launched by India's own launch vehicle, making it a significant achievement in the country's space program.
The launch of Rohini was a result of years of research and development by ISRO. The Satellite Launch Vehicle (SLV-3) was designed to carry a payload of up to 150 kg to a low Earth orbit. The successful launch of Rohini demonstrated India's capability to develop and launch its own satellites, which was a major step forward in the country's space ambitions.
Understanding the history of India's space program is essential for students preparing for competitive exams, as questions related to significant milestones in the country's scientific achievements often appear in such examinations. The launch of the Rohini satellite in 1980 is a key event that should be remembered for its historical and technological significance.
