In his last 'Mann Ki Baat', Mr Modi congratulated ISRO for successfully launching 104 satellites on a single rocket.
"After the success of Mangalyaan, the 104 satellite launch on a single rocket is another feather in ISRO's cap... I congratulate them on behalf of countrymen," Mr Modi had said.
He also spoke on India's successful ballistic missile interceptor test, the need and importance of science and agronomy.
