ISRO’s reputation increasing in international satellite launch market after GSLV launch


Indian Space Research Organisation (ISRO) has completed another milestone by successfully lifting the Geosynchronous Satellite Launch Vehicle GSLV-F05 rocket from Sriharikota on September 8. Scientists at the Indian space agency used indigenous cryogenic upper stage engine to successfully locate the heavy weather satellite INSAT-3DR  weighing 2800 kg into the orbit. The satellite will enhance the accuracy of weather prediction giving the necessary edge in international space commerce in future.

The launch was planned to initiate at 4:10PM but due to some technical issues it got delayed by 40 minutes. However, everything went smooth and the rocket was blasted from the Satish Dhawan Space Center in Sriharikota, at 4:50PM.

The successful launch of over two-tonne satellite has put India in the elite league of nations able to lift up such heavy satellites in the geostationary orbit. Only five other nations — US, Russia, France, Japan and China, have the cryogenic engine technology to lift such heavy satellites.

While talking of the dimensions, the GSLV-F05 rocket is 161-fot-tall. After few failures during the initial development phases, the rocket has had three consecutive successful flights including the one on Thursday. A solid-fueled first stage motor and four strap-on Vikas engines consuming a mixture of liquid hydrazine and nitrogen tetroxide powered the initial two minutes of the ascent. It took 17 minutes for the GSLV with cryogenic engine to release the satellite into the planned orbit of Earth.

The successful launch has given India another rocket after PSLV which India’s most successful rocket. However, GSLV will be used in future to launch heavyweight satellites.

Apparently, the successful launch of India’s weather observatory has increased the reputation of Indian space agency ISRO in the international satellite launch market worth $300 billion. After the success of missions like Mangalyaan that won the Space Pioneer award 2015 and got featured in Times Magazine, and Chandrayaan, foreign agencies have started seeking help of ISRO for their satellite launches. ISRO has launched 51 foreign satellites till date.

Moreover, two more GSLV-MkII missions will be completed this year. In addition, ISRO is developing C-25 engine which will twice powerful than the current version having the capability to lift satellite weighing over 4,000kg.
