An Indian rocket carrying 16 loads of equipment and experiments including an earth surveillance satellite went off track after liftoff on Monday in a fresh setback to the workhorse launch vehicle of the Indian Space Research Organisation.

It was a second disappointment for the Polar Satellite Launch Vehicle in about eight months, denting its reputation for reliability, with a more than 90 per cent success rate over about 60 past missions.

The PSLV-C62 lifted off from the Satish Dhawan Space Centre on the island of Sriharikota at 10:18 a.m. (04488 GMT) carrying the EOS-N1 observation satellite and 15 other payloads developed by startups and academic institutions in India and abroad.
