Sriharikota: The Indian Space Research Organisation (ISRO) on Wednesday launched the GSLV-MK-III D2 carrying GSAT-29 satellite from Satish Dhawan Space Centre in Sriharikota. The 27-hour countdown for the same began on Tuesday.

Briefing about the development, the ISRO had said on Tuesday, “The countdown has begun today 14:50 hrs for the launch of GSLVMkIII D2 carrying GSAT29 at Sriharikota (over 100 km from here). Launch scheduled at 17.08 IST on November 14.”

Terming the launch of GSLV-MkIII-D2 as one of the “very important missions and a milestone” for India’s space programme, ISRO Chairman K Sivan said, “This is GSLV-MkIII-D2 second developmental flight. It is going to launch very important and high throughput satellite GSAT-29. The satellite will be useful in Jammu and Kashmir and North East region for providing connectivity under the Centre’s Digital India programme.”

He had also informed that the GSLV-MkIII is going to launch the Chandrayaan-II and also the manned mission and the ISRO is getting prepared for that.

Prime Minister Narendra Modi congratulated the team on Twitter. “My heartiest congratulations to our scientists on the successful launch of GSLV MK III-D2 carrying GSAT-29 satellite. The double success sets a new record of putting the heaviest satellite in orbit by an Indian launch vehicle,” he posted.

GSLV-MkIII is the fifth generation launch vehicle developed by ISRO and is designed to place satellites of upto 4,000 kg in GTO. The launch vehicle is the 67th launch mission from the Satish Dhawan Space Centre at Sriharikota and the 33 communication satellite built by ISRO for which this will be be the fifth launch this year.

The GSLV-MkIII-D2 is a three stage launch vehicle with two solid strap-ons, a liquid core stage and a cryogenic upper stage.Compared to solid and liquid stages, the C25 cryogenic stage is more efficient as well as complex.

According to the ISRO, the GSAT-29 satellite is intended to serve as a test bed for several new technologies. It is specifically designed to cater to communication requirements of users from remote areas of the country. It carries Ka and Ku band high throughput transponders intended to meet the communication requirements of users. The mission life is about 10 years.
