"Need Bigger Rockets In Future, Can't Live On Frugal Engineering Alone": Ex-ISRO Chief K Sivan

India's Mars mission may have cost less than some Hollywood films, but the era of jugaad and frugal engineering in the country will need to make way for more money and bigger rockets in the future, former ISRO chief K Sivan has said. In an exclusive interview with NDTV today, Mr Sivan said, "We need bigger rockets and bigger systems. We cannot live with frugal engineering alone. We need to have high-power rockets and high-end technology. For that, this government has done one good thing: they have opened up space activities to private industries."
