The first Indian satellite was Aryabhata, named after the famous Indian astronomer. It was launched on 19 April 1975 from Kapustin Yar, a Soviet rocket launch and development site in Astrakhan Oblast using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation (ISRO), and launched by the Soviet Union as a part of the Soviet Interkosmos programme which provided access to space for friendly states.

Aryabhata was a 360 kg satellite that carried four scientific instruments: a cosmic ray telescope, a solar X-ray telescope, a magnetometer, and a spectrograph. It orbited the Earth at an altitude of 580 kilometers and had a lifespan of nearly 17 years.

The launch of Aryabhata was a major milestone in India's space program. It demonstrated that India had the capability to design, build, and launch its own satellites. The success of Aryabhata also helped to boost India's international prestige and paved the way for future space missions.
