MUMBAI: Precisely at 5.08 p.m. Wednesday the GSLV-Mk III rocket on its second developmental flight began its ascent with a strong deep growl that reverberated like a thunder roll breaking free from the second launch pad at the Satish Dhawan Space Centre (SDSC) in Sriharikota carrying communications satellite GSat29.

The Indian space agency had flown a similar rocket on June 5, 2017, with GSAT-19 satellite. Prior to that ISRO had flown another rocket with 3.7-tonne dummy payload in 2014 to test its in-flight structural stability and aerodynamics, according to wire agency reports.

According to Indian Space Research Organisation (ISRO), GSat29 with a life span of 10 years is a multi-beam satellite that carries Ka/Ku-band high throughput communication transponders intended to meet the communication requirements of users including those in remote areas.

In addition, several new technologies such as Q/V-band payload, data transmission through optical communication link will be demonstrated. This will help in realising future advanced satellites, ISRO said.

ISRO chairman K. Sivan said the launch was one of the “very important missions and a milestone” for India’s space programme.

“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”, Sivan was quoted by agencies as saying.

According to the ISRO, the GSat29 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.
