What have been the major achievements of ISRO?
India's first satellite Aryabhata was built by ISRO and launched by the erstwhile Soviet Union in 1975. India's first lunar probe 'Chandrayaan' was launched by the organisation in 2008 while India became the first Asian country to reach Mars orbit with 'Mangalyaan' in 2014. ISRO created a world record by launching 104 satellites from a single rocket earlier this year.
