At 23 seconds of the video, a clear separation of the heat shield - that protects the space vehicle from the high temperatures generated due to friction as it leaves the Earth's atmosphere -- is seen, something that did not happen during the earlier launch in August last year.
"Cartosat 2", the heaviest of the satellites carried by the rocket, was the first to be ejected. The surveillance satellite that weighs 710 kilograms will also help India monitor its borders and keep an eye on neighbours.
The rocket lifted off at 9.29 am from the Satish Dhawan Space Centre. On board were satellites from the United States, United Kingdom, France, Canada, Republic of Korea and Finland. President Ram Nath Kovind, Vice-President M Venkaiah Naidu and Prime Minister Narendra Modi had congratulated ISRO on the successful launch of the rocket that carried 31 satellites weighing over 1300 kilograms.
