Why ISRO's GSLV Was Known As 'Naughty Boy', And How The Launch Vehicle Earned The Moniker 'Smarty Boy'

ISRO's Geosynchronous Satellite Launch Vehicle (GSLV) was earlier known as "naughty boy", but now, after successfully placing INSAT-3DS into intended orbit, it has earned the sobriquet "smarty boy".

The INSAT-3DS mission, also known as GSLV-F14, was GSLV's 16th flight, and its 10th successful mission. Out of 15 previous missions, four were failures, two partial failures, and nine successful. Meanwhile, PSLV has a success rate of 95 per cent, and a failure rate of five per cent.
