Which of the following is not the satellite launched by India?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Explorer
Explorer is a series of satellites of the United States; Explorer 1, launched in January 1958, was America’s first satellite.
The other three are Indian satellites built by ISRO: Bhaskara (1979), an early earth-observation satellite; APPLE (1981), India’s first experimental communication satellite; and INSAT, the series of communication and weather satellites. Some of them were carried into orbit by foreign rockets, but they are India’s own satellites.
