ISRO successfully launches India’s heaviest rocket GSLV Mark-III

December 18, 2014

Sriharikota, Dec 18: India Thursday moved forward in rocket technology with the successful flight testing of its heaviest next generation rocket and the crew module.

firePrecisely at 9.30 a.m., the 630 tonne Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mark III) standing 43.43 metre tall freed itself from the second launch pad and with a reverberating deep throated roar, rose into the sky.

With a thick orange flame at its tail, the expendable rocket ascended towards the heavens with one way ticket as its design life span is just around five minutes.

The Rs.155 crore mission has twin purposes. The main purpose is to test the rocket's atmospheric flight stability with around four tonne luggage.

The second and incidental objective is to study the re-entry characteristics of the crew module-called Crew Module Atmospheric Re-entry Experiment - its aero braking and validation of its end-to-end parachute system.

According to an Indian Space Research Organisation (ISRO) official, it will be of the size of a small bedroom and can accommodate two to three people. Just over five minutes into the flight, the rocket spat out the giant cup cake shaped 3.7-tonne crew module at an altitude of 126 km.

The crew module then descended towards Earth at a high speed. The speed was moderated remotely manipulating its on-board motors till 80 km above the earth.

From here the ballistic re-entry into the atmosphere began while the on-board thrusters were shut down. The crew module's heat shield was expected to experience a heat of around 1,600 degrees centigrade.

At an altitude of around 15 km, the module's apex cover separated and the parachutes were deployed.

The module soft crashed in Bay of Bengal near Andaman and Nicobar Islands.

From here, the crew modules multi-modal and multi-state transport journey would begin.

A naval ship tracking the signals from the module will pick up the module and deliver it at the Ennore Port near Chennai in Tamil Nadu. From there it will be brought to Sriharikota in Andhra Pradesh and then it will be taken to the Vikram Sarabhai Space Centre, Thiruvanthapuram in Kerala.

At the mission control centre there was no control on ISRO's scientists happiness at the success.

Speaking about the mission, ISRO's Chairman K. Radhakrishan said: "India started development of the rocket a decade ago and today completed the first experimental flight.

"The performance of the solid and the liquid engines were as expected," he said. "The unmanned crew module splashed in Bay of Bengal as expected," he added.

S. Somanath, project director of GSLV Mark III, said: "India now has a new launch vehicle. The payload capability of the Indian rocket has been enhanced significantly."

The Thursday mission success is sweet for the Indian space fraternity as it comes after successful launch of Mars Orbiter last year and older version of GSLV rocket powered by its own cryogenic engine early this year.

A cryogenic engine is more efficient as it provides more thrust for every kilogram of propellant burnt.

This was the second mission of GSLV rocket during the last four years after two such rockets failed in 2010. The GSLV-Mark III is designed to be a three stage/engine rocket with a lift off weight of 630 tonnes.

The first stage comprises two identical S-200 large solid boosters with 200 tonne solid propellant, that are strapped on to the second stage, the L110 re-startable liquid stage.

The third stage/engine is the cryogenic. For the country ISRO perfecting the cryogenic engine technology is crucial as precious foreign exchange can be saved by launching communication satellites by itself.

Mumbai, May 22: The Reserve Bank of India (RBI) on Friday reduced repo rate by 40 basis points to 4 per cent in an effort to further boost liquidity in the economy which has been reeling under the impact of COVID-19 induced countrywide lockdown.

As a result, the reverse repo rate stands at 3.35 per cent, said RBI Governor Shaktikanta Das. The six-member monetary policy committee (MPC) voted 5:1 in favour of the decision.

Repo rate is the rate at which a country's central bank lends money to commercial banks, and the reverse repo rate is the rate at which it borrows from them.

New Delhi, Feb 19: India will switch to the world's cleanest petrol and diesel from April 1 as it leapfrogs straight to Euro-VI emission compliant fuels from Euro-IV grades now - a feat achieved in just three years and not seen in any of the large economies around the globe.

India will join the select league of nations using petrol and diesel containing just 10 parts per million of sulphur as it looks to cut vehicular emissions that are said to be one of the reasons for the choking pollution in major cities.

Sanjiv Singh, Chairman of Indian Oil Corp (IOC) - the firm that controls roughly half of the country's fuel market, said almost all refineries began producing ultra-low sulphur BS-VI (equivalent to Euro-VI grade) petrol and diesel by the end of 2019 and oil companies have now undertaken the tedious task of replacing every drop of fuel in the country with the new one.

"We are absolutely on track for supplying BS-VI fuel from April 1. Almost all refineries have begun supplying BS-VI fuel and the same has reached storage depots across the country," he said.

From storage depots, the fuel has started travelling to petrol pumps and in the next few weeks all of them will only have BS-VI grade petrol and diesel, he said. "We are 100 per cent confident that fuel that will flow from nozzles at all the petrol pumps in the country on April 1 will be BS-VI emission compliant fuel."

India adopted Euro-III equivalent (or Bharat Stage-III) fuel with a sulphur content of 350 ppm in 2010 and then took seven years to move to BS-IV that had a sulphur content of 50 ppm. From BS-IV to BS-VI it took just three years.

"It was a conscious decision to leapfrog to BS-VI as first upgrading to BS-V and then shifting to BS-VI would have prolonged the journey to 4 to 6 years. Besides, oil refineries, as well as automobile manufacturers, would have had to make investments twice - first to producing BS-V grade fuel and engines and then BS-VI ones," he said.

State-owned oil refineries spent about Rs 35,000 crore to upgrade plants that could produce ultra-low sulphur fuel. This investment is on top of Rs 60,000 crore they spent on refinery upgrades in the previous switchovers.

BS-VI has a sulphur content of just 10 ppm and emission standards are as good as CNG.

Originally, Delhi and its adjoining towns were to have BS-VI fuel supplies by April 2019 and the rest of the country was to get same supplies from April 2020.

But oil marketing companies switched over to supply of BS-VI grade fuels in the national capital territory of Delhi on April 1, 2018.

The supply of BS-VI fuels was further extended to four contiguous districts of Rajasthan and eight of Uttar Pradesh in the National Capital Region (NCR) on April 1, 2019, together with the city of Agra.

BS-VI grade fuels were made available in 7 districts of Haryana from October 1, 2019.

Singh said the new fuel will result in a reduction in NOx in BS-VI compliant vehicles by 25 per cent in petrol cars and by 70 per cent in diesel cars.

The switchover, he said, is a tedious task as every drop of old, higher-sulphur content fuel has to be flushed out in depots, pipelines and tanks before being replaced by BS-VI.

"We are confident of disruption-free switchover to BS-VI supplies across the country," he said. "What we will be supplying is the best quality available anywhere in the world. You don't have any better fuel that is supplied in any part of the world. Perhaps our BS-VI fuel will be better than equivalent fuel in some parts of the US and Europe."

India adopted a fuel upgradation programme in the early 1990s. Low lead gasoline (petrol) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, unleaded gasoline was mandated nationwide.

Similarly, BS-2000 (Euro-I equivalent, BS-1) vehicle emission norms were introduced for new vehicles from April 2000. BS-II (Euro-II equivalent) emission norms for new cars were introduced in Delhi from 2000 and extended to the other metro cities in 2001.

Benzene limits have been reduced progressively from 5 per cent in 2000 to 1 per cent nationwide. Lead content in gasoline was removed in phases and only unleaded gasoline is being produced and sold from February 1, 2000.

The octane number of gasoline signifies the improved performance of the engine. Loss in octane number due to phasing out of lead was made up by installing new facilities in the refinery and changes in refinery operation. RON (Research Octane Number) of gasoline for BS-2000 spec was increased to 88. This has over time been increased to 91.

Singh said sulphur reduction will reduce Particulate Matter (PM) emissions even in the in-use older generation diesel vehicles.

Washington, Jul 18: The Foreign Direct Investment (FDI) from the US to India has crossed the $40 billion mark so far this year, reflecting the growing confidence of American companies in the country, the head of an India-centric business advocacy group has said.

The American companies, during the Covid-19 pandemic, which has battered the world economy, have shown great confidence in India and its leadership, said Mukesh Aghi, president of the US-India Strategic and Partnership Forum (USISPF), which keeps a track of the major US FDIs in India.

“Year to date investment from the US, including the recent ones, is over $40 billion,” Aghi said.

In recent weeks alone, the announcement of the FDI into India has been over $20 billion, he said, referring to the announcements made by some of the top companies like Google, Facebook and Walmart.

“Investors’ confidence in India is high. India still remains a very promising market for global investors. If you look at the $20 billion… not just the US, but (investment) has also come from other geographies such as the Middle East and the Far East.

“So, India still remains a very, very bullish market for the investor community,” Aghi said in response to a question.

The USISPF has been working with New Delhi to bring in FDI into India… playing a key role in encouraging American companies planning to move their bases out of China, he said, adding that the move was going on in the last three years of the Trump administration, but gained momentum during the coronavirus pandemic.

“We feel that Prime Minister (Narendra Modi’s) intention is very high. The challenges lie on the execution side. Efforts are being made to encourage manufacturing… I've never seen it so better. The policy framework is moving in the right direction,” he said.

Early this week, Larry Kudlow, the White House Economic Advisor, told reporters that the US tech giants like Google and Facebook announcing big investments in India shows that people are losing trust in China and India is emerging as a big competitor.

At the same time, he rued that India continues to be a protectionist country.

“The question is how do you define protectionism... the administration here is saying America first and India is saying vocal for local…,” Aghi added.
