India's first satellite, launched in 1975, was named after which ancient Indian astronomer and mathematician?
- A.Aryabhata
- B.Brahmagupta
- C.Bhaskara
- D.Varahamihira
Correct answer
Explanation
The correct answer is A, Aryabhata. India's first satellite, launched in 1975, was named Aryabhata after the astronomer who wrote the Aryabhatiya in 499 CE, explained day and night by the rotation of the earth on its axis and gave a value of pi equivalent to 3.1416. Option B is wrong because no Indian satellite of that first series was named Brahmagupta, although his Brahmasphutasiddhanta of 628 CE is the work that fixed the rules of arithmetic with zero. Option C is wrong only in respect of the order and the year: satellites named Bhaskara did follow, but after Aryabhata. Option D is wrong because Varahamihira, the author of the Panchasiddhantika, has not given his name to a satellite of this series. Aryabhata was launched in April 1975 from a Soviet cosmodrome, and the name is the standard link in question papers between ancient Indian astronomy and the modern Indian space programme.
