Aryabhat was launched in the year _________.

1975

The correct answer is Option (1) → 1975

As per NCERT books till 2023-24, it is mentioned that Aryabhatt was launched on 19 April 1979. However, this is wrongly mentioned as Aryabhata was India’s first satellite, launched on April 19, 1975 (not 1979) by the Soviet Union from the Baikonur Cosmodrome. This fact has been corrected in the new NCERT books where in correct year has been mentioned as 1975..
