Aryabhatta
India's First Artificial Satellite: Aryabhatta
The question asks for the name of the first artificial satellite launched by India in 1975. Understanding key historical milestones in space exploration is important for general knowledge and exam preparation.
India's journey in space technology began significantly in the mid-1970s. The launch of its first satellite marked a major step forward for the nation's scientific capabilities.
Identifying the First Indian Satellite
Let's look at the options provided:
- Charaka
- Panini
- Aryabhatta
- Sushruta
These names are associated with famous historical figures from ancient India:
- Charaka was a major contributor to the ancient Indian science of Ayurveda.
- Panini was a Sanskrit grammarian who wrote the Ashtadhyayi.
- Sushruta was an ancient Indian surgeon and is considered one of the founders of surgery.
- Aryabhatta was a great ancient Indian mathematician and astronomer.
Among these options, one name stands out as related to astronomy and mathematics, fields closely linked to space science. The correct answer is indeed named after the famous astronomer.
The Aryabhatta Satellite
India's first artificial satellite was named Aryabhatta. It was launched on April 19, 1975, from Kapustin Yar, a Soviet cosmodrome, using a Kosmos-3M launch vehicle. The satellite was built by the Indian Space Research Organisation (ISRO).
The Aryabhatta satellite was designed to conduct experiments in:
- X-ray astronomy
- Solar physics
- Aeronomy
Although the satellite's mission life was short due to a power failure after just a few days, it successfully orbited the Earth for several years and provided valuable data. Its launch was a monumental achievement for India, demonstrating its capability to design and build complex spacecraft.
Conclusion on India's First Satellite
Based on the historical facts about India's space program, the first artificial satellite launched by India in 1975 was Aryabhatta. The other options are names of significant ancient Indian scholars but are not associated with India's satellite program.
Therefore, the correct option is Aryabhatta.

Additional Information: ISRO and India's Space Program
The Indian Space Research Organisation (ISRO) is India's national space agency. It was founded in 1969. ISRO is responsible for the design, development, and operation of spacecraft and launch vehicles.
The launch of Aryabhatta in 1975 was a foundational step for ISRO. Since then, India has made significant advancements in space technology, developing its own launch vehicles like PSLV (Polar Satellite Launch Vehicle) and GSLV (Geosynchronous Satellite Launch Vehicle) and launching numerous satellites for communication, navigation, earth observation, and scientific research, as well as undertaking ambitious interplanetary missions like Chandrayaan (to the Moon) and Mangalyaan (to Mars).
