India is set to launch its weather satellite INSAT-3DR using geosynchronous satellite launch vehicle GSLV-MkII will start at 11.10 AM today, the Indian Space Research Organisation (ISRO) said. The Mission Readiness Review (MRR) committee and the Launch Authorisation Board (LAB) cleared the GSLV rocket launch slated for 4.10 p.m. on September 8, ISRO said. Blasting off from the second launch pad at India’s rocket port at Sriharikota in Andhra Pradesh, the GSLV rocket will put the 2,211 kg INSAT-3DR an advanced weather satellite into a geostationary transfer orbit. The Indian Space Research Organisation (ISRO) is gearing up to launch its Geosynchronous Satellite Launch Vehicle (GSLV). It will carry into orbit an advanced weather satellite named INSAT-3DR. Liftoff will take place at 4:10 p.m. local time, from the second launch pad at the Satish Dhawan Space Centre in Sriharikota, India.

The satellite from there will reach the final geosynchronous orbit on its own. The satellite will supplement the meteorological and data relay services of its predecessor INSAT-3D, which is in operation since July 26, 2013. Earlier a senior ISRO official had said the Indian weather satellite will be launched on August 28. However, while carrying out the tests, a technical issue was found with a satellite component postponing the launch to September 8. According to ISRO officials, ISRO will launch ScatSat — a weather monitoring and forecasting satellite — with polar satellite launch vehicle (PSLV) end of next month. The Indian satellite will be a co-passenger to an Algerian satellite-Alsat. Also Read - Ola to offer free oxygen concentrators to the needy
Both the satellites will be put into different orbits. So the fourth stage/engine of the rocket will be switched off after ejecting ScatSat first. Then after a gap of around 30 minutes, the engine will be switched on and put the Algerian satellite into its intended orbit.
INSAT-3DR is the second satellite in the series. The first spacecraft, INSAT-3D, was launched into space July 25, 2013, atop an Ariane 5 booster from Kourou, French Guiana. Once in orbit, INSAT-3DR will join the operational search and rescue service provided by INSAT 3D to various users, including the Indian Coast Guard, Airport Authority of India, Shipping, and Defense Services.
The GSLV that will be used in Thursday’s mission is an expendable launch system developed to enable India to launch its satellites without dependence on foreign launch service providers. It uses major components that have already been proven by the Polar Satellite Launch Vehicle (PSLV) launchers in the form of the S125/S139 solid rocket booster and the liquid-fueled Vikas engine. The overall length of the launcher is 161 feet (49 meters) with a liftoff mass of 415 metric tons.
Indian Space Research Organization recently announced its plans to launch five satellites in two different orbits in September, with two launches in a month for the first time. The satellites will be launched from the state-run space agency’s rocketport at Sriharikota in Andhra Pradesh, about 80 km northeast of Chennai. The 2.2-tonne weather satellite will be launched on a heavier rocket, Geo-synchronus Satellite Launch Vehicle (GSLV Mark II), as it will be deployed in a geostationary orbit at 74 degrees East, about 36,000 km from the earth. The other four satellites will be launched on the space agency’s reliable workhorse, Polar Satellite Launch Vehicle (PSLV), and deployed in the earth’s lower orbits. The weather satellite will have a six-channel imager and a 19-channel sounder. It will also carry a search and rescue information and message relay for terrestrial data collection platforms.
