Which was the first satellite of India, launched in 1975 from the Soviet Union?
- A.Bhaskara
- B.Aryabhata
- C.Rohini
- D.APPLE
Correct answer
Explanation
The correct answer is B, Aryabhata. Aryabhata was the first satellite built by India and it was launched on 19 April 1975 from a Soviet launch site, since India had no launch vehicle of its own at the time. It was named after the ancient Indian astronomer and mathematician, and it carried experiments in X-ray astronomy, solar physics and the study of the ionosphere. It marks the beginning of the Indian satellite programme.
Option A, Bhaskara, was an experimental earth observation satellite launched later, in 1979. Option C, Rohini, refers to the series of which RS-1 became the first satellite placed in orbit by an Indian launch vehicle, the SLV-3, on 18 July 1980. Option D, APPLE, was the Ariane Passenger Payload Experiment of 1981, the first Indian experimental communication satellite in geostationary orbit. Keep the order Aryabhata, Bhaskara, Rohini, APPLE in mind.
