India's advanced weather satellite INSAT-3DR launch delayed by 40 minutes

The lift-off was scheduled to take place at scheduled to take place from the second launch pad at the spaceport of Sriharikota, about 110-km from Chennai.

The launch of an Indian Geosynchronous Satellite Launch Vehicle (GSLV) rocket carrying weather satellite INSAT-3DR has been delayed by 40 minutes.  The delay in the launch was reportedly because of the filling of fuel in the cryogenic stage, said a senior official. He said the revised launch time is scheduled for 4.50 p.m. Originally the launch time was 4.10 p.m. The GSLV rocket will put 2,211 kg INSAT-3DR, weather satellite into a orbit after blasting off from the second launch pad at India’s rocket port at Sriharikota in Andhra Pradesh. “Some technical anomaly was found during the filling of fuel in the cryogenic engine. The issue was sorted out and the fuelling operations have restarted. Hence the delay,” a senior official of the Indian Space Research Organisation (ISRO) told IANS.

The satellite will supplement the meteorological and data relay services of its predecessor INSAT-3D, which is in operation since July 26, 2013. The satellite was supposed to be launched on August 28 but this was postponed owing to a technical issue with one of its components. According to ISRO, the second stage/engine was fuelled up on Wednesday evening. According to the space agency officials, ISRO will launch ScatSat — a weather monitoring and forecasting satellite — with polar satellite launch vehicle (PSLV) at the end of the month.

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 image and a 19-channel sounder. It will also carry a search and rescue information and message relay for terrestrial data collection platforms.
