Better weather forecasting will save lives...

New Delhi :

When India launches its latest weather satellite on Saturday, it will use a rocket that the Indian space agency has nicknamed "Naughty Boy." Geosynchronous Satellite Launch Vehicle (GSLV) is scheduled to lift off with INSAT-3DS satellite from Sriharikota in Andhra Pradesh on Saturday evening at 5.35 pm. A former ISRO chairman had called it a "naughty boy". Since, this rocket has not performed well in six of its 15 flights. The last launch of GSLV on May 29, 2023 was successful, but the previous launch on August 12, 2021 was unsuccessful.

ISRO's Bahubali...

Compared to Naughty Boy, GSLV Mark-3 aka 'Bahubali Rocket' has completed seven flights and has created a record of 100 percent success. ISRO's workhorse rocket, the Polar Satellite Launch Vehicle (PSLV), also has a success rate of 95 percent, with only three failures in 60 launches. Let us tell you that GSLV is a three-stage rocket, whose length is 51.7 meters. Its weight is 420 tonnes. The rocket uses an Indian-made cryogenic engine and ISRO plans to retire it after a few more launches.

The satellite to be launched is very special

The satellite being launched on Saturday is very special... and much needed, as it will help boost India's weather and climate monitoring services. Called INSAT-3DS, it is a third-generation upgraded, dedicated meteorological satellite. The satellite weighs 2,274 kg and has been built at a cost of approximately Rs 480 crore. ISRO said, "It is completely funded by the Ministry of Earth Sciences.

Better weather forecasting will save lives...

ISRO officials said that the new weather monitoring satellite is designed for meteorological forecasting, disaster warning, monitoring of land and ocean surfaces. India is using these eyes in the sky to help its weather office deliver increasingly accurate forecasts, which often help save lives. Better weather forecasting can save lives. 

Weather satellites have been a game changer

Dr M Ravichandran is an accomplished atmosphere and ocean science expert and is the Secretary of the Ministry of Earth Sciences. He said, "Indian weather satellites have been a game changer. Satellites are truly our eyes in the sky, which have helped India forecast cyclones with great accuracy." He said, "About 300,000 people died due to cyclones originating in the Bay of Bengal during the 1970s, but this was before Indian weather satellites came into existence. Now, India is using its own constellation of dedicated satellites .They make cyclone forecasts...so accurate that the death toll has dropped to double digits or sometimes to none at all."

India currently has three working weather satellites: INSAT-3D, INSAT-3DR, and OceanSat.

There was a need for replacement satellite

Dr. Ashim Kumar Mitra, Project Director, Satellite Meteorology Department, India Meteorological Department (IMD), said, “Insat-3D is nearing the end of its life after being in service since 2013, hence there was a need for a replacement satellite. " Explaining how weather satellites provide data for forecasting, Dr Mitra said, “Satellites basically measure the brightness coming from the Earth's surface and cloud tops. By making such measurements at appropriate wavelengths and using physical and statistical By applying the techniques, it is possible to calculate a wide range of products for weather monitoring and forecasting. Furthermore, satellite meteorological data at the global scale are important inputs into numerical weather prediction (NWP) models as initial conditions."
