ISRO's heavy-lift rocket GSLV-MkIII-D2 blasted off from Sriharikota on Wednesday, carrying India's latest communication satellite GSAT-29 onboard.
The 27-hour countdown for the launch began at 2.50pm on Tuesday and the rocket blasted off at 5.08 pm from the spaceport at Sriharikota over 100km from Chennai.
The 3,423kg GSAT-29 carries Ka and Ku band high throughput transponders intended to meet the communication requirements of users, including in the Northeast and in Jammu and Kashmir.
The satellite is scheduled be injected into a geosynchronous orbit, 18 minutes after lift-off.
Cyclone Gaja had clouded the launch plans but with it changing course and conducive weather conditions prevailing, the rocket blasted off on schedule.
