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.

New Delhi, May 4: The country's manufacturing sector activity witnessed unprecedented contraction in April amid national lockdown restrictions, following which new business orders collapsed at a record pace and firms sharply reduced their staff numbers, a monthly survey said on Monday.

The headline seasonally adjusted IHS Markit India Manufacturing Purchasing Managers' Index (PMI) fell to 27.4 in April, from 51.8 in March, reflecting the sharpest deterioration in business conditions across the sector since data collection began over 15 years ago.
The index slipped into contraction mode, after remaining in the growth territory for 32 consecutive months.

In PMI parlance, a print above 50 means expansion, while a score below that denotes contraction.

Amid widespread business closures, demand conditions were severely hampered in April. New orders fell for the first time in two-and-a-half years and at the sharpest rate in the survey's history, far outpacing that seen during the global financial crisis, the survey said.

"After making it through March relatively unscathed, the Indian manufacturing sector felt the full force of the coronavirus pandemic in April," said Eliot Kerr, Economist at IHS Markit.
Panellists attributed lower production to temporary factory closures that were triggered by restrictive measures to limit the spread of COVID-19.

Export orders also witnessed a sharp decline. Following the first reduction since October 2017 during March, foreign sales fell at a quicker rate in April. "In fact, the rate of decline accelerated to the fastest since the series began over 15 years ago," the survey said.

On the employment front, deteriorating demand conditions saw manufacturers drastically cut back staff numbers in April. The reduction in employment was the quickest in the survey's history.

"In the latest survey period, record contractions in output, new orders and employment pointed to a severe deterioration in demand conditions.
“Meanwhile, there was evidence of unprecedented supply-side disruption, with input delivery times lengthening to the greatest extent since data collection began in March 2005," Kerr said.

On the prices front, both input costs and output prices were lowered markedly as suppliers and manufacturers themselves offered discounts in an attempt to secure orders.

Going ahead, sentiment regarding the 12-month outlook for production ticked up from March's recent low on hopes that demand will rebound once the COVID-19 threat has diminished and lockdown restrictions eased.

"There was a hint of positivity when looking at firms' 12-month outlooks, with sentiment towards future activity rebounding from March's record low. That said, the degree of optimism remained well below the historical average," Kerr said.

In India, the death toll due to COVID-19 rose to 1,373 and the number of cases climbed to 42,533 as on Monday, according to the health ministry.

Meanwhile, the coronavirus-induced lockdown has been extended beyond May 4, for another two weeks in the country.

New Delhi, Jun 14: Petrol price on Sunday was hiked by a record 62 paise per litre and that of diesel by 64 paise as oil companies for the eighth day in a row adjusted retail rates in line with cost since ending an 82-day hiatus in rate revision.

Petrol price in Delhi was hiked to Rs 75.78 per litre from Rs 75.16 while diesel rates were increased to Rs 74.03 a litre from Rs 73.39, according to a price notification of state oil marketing companies.

Rates have been increased across the country and vary from state to state depending on the incidence of local sales tax or VAT.

The 62 paise a litre increase in petrol and 64 paise hike in diesel price is the highest surge in rates since the daily price revision was started in June 2017.

This is the eighth daily increase in rates in a row since oil companies on June 7 restarted revising prices in line with costs, after ending an 82-day hiatus.

In eight hikes, petrol price has gone up by Rs 4.52 per litre and diesel by Rs 4.64 -- a record increase in rates in any eight days since the daily price revision was introduced.

The freeze in rates was imposed in mid-March soon after the government hiked excise duty on petrol and diesel to shore up additional finances.

Oil PSUs Indian Oil Corp (IOC), Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corp Ltd (HPCL), instead of passing on the excise duty hikes to customers, adjusted them against the fall in the retail rates that was warranted because of international oil prices falling to two-decade lows.

The government had first raised excise duty on petrol and diesel by Rs 3 per litre each on March 14 and then again on May 5 by a record Rs 10 per litre in case of petrol and Rs 13 on diesel. The two hikes gave the government Rs 2 lakh crore in additional tax revenues.

State-owned fuel retailers IOC, BPCL and HPCL had frozen petrol and diesel prices since March 16, as if anticipating the government move and set off gains they accrued from continuing drop in international oil prices against the excise duty hike.

They, however, promptly passed the increase in local sales tax or VAT by state governments such as Rs 1.67 increase in VAT on petrol and Rs 7.10 in diesel by the Delhi government on May 4.

The total incidence of excise duty on petrol has risen to Rs 32.98 per litre and that on diesel to Rs 31.83. The excise tax on petrol was Rs 9.48 per litre when the Narendra Modi government took office in 2014 and that on diesel was Rs 3.56 a litre.

The government had between November 2014 and January 2016 raised excise duty on petrol and diesel on nine occasions to take away gains arising from plummeting global oil prices.

In all, duty on petrol rate was hiked by Rs 11.77 per litre and that on diesel by 13.47 a litre in those 15 months that helped government's excise mop up more than double to Rs 2,42,000 crore in 2016-17 from Rs 99,000 crore in 2014-15.

It cut excise duty by Rs 2 in October 2017 and by Rs 1.50 a year later. But it raised excise duty by Rs 2 per litre in July 2019.

It again raised excise duty on March 14 by Rs 3 per litre.
