ISRO begins countdown for launch of 20 satellites

Chennai: The 48-hour countdown for the launch of India’s Cartosat-2 series and 19 other satellites slated for Wednesday, began on Monday morning, the Indian space agency said.

According to Indian Space Research Organisation (ISRO), on Wednesday at 9.25 a.m., Indian rocket Polar Satellite Launch Vehicle (PSLV) will lift off from the rocket port at Sriharikota in Andhra Pradesh with 20 satellites.

The rocket’s main cargo will be India’s 725.5 kg Cartosat-2 series satellite for earth observation.

The other 19 satellites weighing totally around 560 kg are from US, Canada, Germany and Indonesia as well as one satellite each from Chennai’s Sathyabama University and College of Engineering, Pune.

The rocket will blast off from the second launch pad with a total payload of 1,288 kg.

The whole mission will get over in around 26 minutes.

The images sent by Cartosat satellite will be useful for cartographic, urban, rural, coastal land use, water distribution and other applications.

On the other hand, the 1.5 kg Sathyabamasat from Sathyabama University will collect data on green house gases while the 1 kg Swayam satellite from College of Engineering, Pune will provide point-to-point messaging services to the HAM radio community.

Wednesday’s mission will be the first time the ISRO will be launching more the 10 satellites with a single rocket.

In 2008, the ISRO had launched 10 satellites with the PSLV rocket.

Electric vehicle versus Fuel vehicle: Which is more affordable and cheap

Published

The electric vehicle industry is booming, but the biggest drawback for the consumer is that they are priced much higher than the traditional fuel vehicles. However, at a time when filling-up a full tank of petrol scooters and motorcycles is fast becoming a dream for many, the alternative to it — electric two-wheelers — seems to offer better running price realisation in the long term.

According to investment bank and financial services firm Morgan Stanley, battery-powered two-wheelers are cheaper to own and run than petrol and diesel equivalents. The running cost of electric vehicles is nearly 5% lower annually compared to a gasoline petrol vehicle, the report showed.

The maths of cheaper electric vehicles

The petrol and diesel prices across the country continued their northward march taking its retail rates to unprecedented levels and burning bigger holes in the consumer’s pockets. The electric vehicle as an option weighs heavy.

Although the fact that EVs are priced significantly higher than the vehicles running on fuel have kept people away from them. But once the infrastructure is in place, the cost really comes down to the electricity unit price, which is much lower than the fuel rates. No matter what the price of crude oil is around the world, in India, the average fuel rates have always remained at ₹70 and ₹80 per litre for diesel and petrol, respectively.

Under the bare minimum conditions, the math becomes even clearer — unit price of electricity multiplied by battery size is equivalent to the cost of running an EV. This also eradicates high fuel costs and provides cheaper maintenance and tax. Electric vehicles also hold their value for longer compared to fuel vehicles, according to a Europe based firm study.
