Which was the first Indian satellite, launched in 1975?
- A.Rohini
- B.Aryabhata
- C.Bhaskara
- D.INSAT-1A
Correct answer
Explanation
The correct answer is B, Aryabhata. India's first satellite was named after the ancient astronomer and mathematician Aryabhata, was built by the Indian Space Research Organisation and was launched in April 1975 from the Soviet Union, since India had no launch vehicle of its own at the time; it carried experiments in X-ray astronomy and solar physics. Option A, Rohini, was the first satellite placed in orbit by an Indian launch vehicle, the SLV-3, in 1980, which is the other half of this pair of questions and the commonest trap. Option C, Bhaskara, was an early experimental earth observation satellite launched at the end of the 1970s. Option D, INSAT-1A, was the first satellite of the Indian National Satellite System for communication, launched in the 1980s. The two names to fix firmly are Aryabhata for the first Indian satellite and Rohini for the first launched by an Indian rocket.

- A.gravity
- B.elasticity
- C.friction
- D.fuel driven
Show answer
A satellite is given the required height and speed by its launch vehicle, and after that no engine is needed: the gravitational pull of the earth alone acts on it and provides the centripetal force that keeps it in a curved path, so the satellite keeps falling towards the earth…
