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.

Ayodhya, Jul 18: The Shri Ram Janmabhoomi Teertha Kshetra Trust has invited Prime Minister Narendra Modi to lay the foundation stone of a grand Ram Temple in Ayodhya either on August 3 or 5, both auspicious dates, said a spokesperson.

PM Modi had announced the formation of the Shri Ram Janmabhoomi Teertha Kshetra Trust on February 5.

Mahant Kamal Nayan Das, the spokesperson of Ram Mandir Trust president Nritya Gopal Das said, "We have suggested two auspicious dates -- August 3 and 5 -- for the prime minister's visit based on calculations of movements of stars and planets."

After a protracted legal tussle, the Supreme Court had on November 9 last year paved the way for the construction of a Ram Temple by a Trust at the disputed site in Ayodhya and directed the Centre to allot an alternative 5-acre plot to the Sunni Waqf Board for building a new mosque at a "prominent" place in the holy town in Uttar Pradesh.

New Delhi, Mar 2: As communal violence spiked in north-east Delhi earlier this week, Hindu, Muslim and Sikh residents of a colony came together and stood guard against frenzied mobs which ran riot in nearby areas vandalising homes, shops and torching cars.

They have not let their guard down even as the situation is limping back to normalcy following four days of violence that has claimed at least 42 lives and left over 200 injured.

The B-Block colony in Yamuna Vihar has a Hindu-dominated Bahjanpura on one side and Muslim populated Ghonda on the other.

People from all faiths in the locality sit outside their homes at night and deal with any suspected outsider, Arib, a dentist in his 30s, said.

"It is the sloganeering by mobs that causes panic in the dead of night. Such slogans are from both sides and we hear groups of people moving forward towards our area.

"This is where we let the Muslim locals deal with Muslim groups and Hindu residents deal with Hindu groups coming from outside," he said.

Businessmen, doctors and people working at government offices stuck together as violence reached its crest on Monday and Tuesday, and have been guarding the locality round the clock.

Earlier, the locals had claimed inadequate police deployment in the area, but were satisfied as patrolling by security personnel increased in the last two days.

Charanjeet Singh, a Sikh who owns a transport firm, said residents have ensured that not too many people gather to guard the colony at night. It has been decided not use sticks or rods, an idea which seems to have worked in maintaining peace, he said.

"I was 10 years old when we came to this locality from Uttar Pradesh's Meerut in 1982. There were riots in 1984 and tension in 2002, but even then our area remained peaceful. We have always been united and that is the way we have helped each other," Singh, who is now in his 50s, told PTI.

Faisal, a businessman in his 30s, said after two days of major violence, there was palpable tension in the area. "Nobody could sleep in the neighbourhood even on Wednesday and Thursday when the situation was brought under control," he said.

Faisal said around 4 am on Wednesday, three to four miscreants had torched a car, but were chased away by vigilant residents. They raised an alarm and others gathered, saving other vehicles parked nearby from being damaged, he added.

On the idea of not keeping sticks while guarding B-Block, Singh said, "Violence begets violence, crowd begets crowd. We thought if somebody would see sticks or rods in our hands from a distance and large crowds standing guard, it is likely they would want to come prepared. This could fuel violence."

"Now, if there is some young man returning late in the night, we identify if he belongs to our area. If not, we normally inform him about the situation and guide him to his destination, if required," he added.

Seventy-year-old V K Sharma said people in his colony never had any trouble with each other, as he blamed "outside elements" for the violence in north-east Delhi.

"Some people have some problem with symbols. If they find a particular religion's symbol on a shop, home or a car, they vandalise it.

"This is on both sides, Hindus as well as Muslims. But not all people in all religion are like that. There are good people who outnumber these handful people involved in violence," he said.

The violence happened for two days but it would take months for fear to subside, Sharma said, as he took out his two granddaughters, aged nine and two, out for ice cream.

"I cannot reduce the tension outside my home, but at least I can make these kids feel good by reducing their craving for ice cream,” he added.

Colony resident Shiv Kumar, a property consultant, and Wasim, a government official, said they too were members of this voluntary guards' team of the colony which stays up at night to fend off miscreants.

Jun 3: Emphasising that airlines are clearly the safest mode of transportation, IndiGo CEO Ronojoy Dutta on Tuesday said there is no evidence yet of coronavirus infection getting transmitted among passengers onboard an aeroplane.

His comments against the backdrop of instances of some passengers, who had taken flights after resumption of domestic air services on May 25, testing positive for coronavirus.

"Those people had the virus before they got on to the aeroplane. What is noteworthy is that they have done the tracing after that. There is no evidence of transmission onboard there... that is a very encouraging sign on the safety of airline travel," he said during an earnings call.

According to him, airlines are clearly the safest mode of transportation and there is no evidence yet of contamination on an aircraft.

"You can come in contaminated but so far there is no evidence of passing it on to a fellow passenger," he noted.

Amid concerns over the coronavirus pandemic, aviation regulator DGCA has asked airlines to ensure that to the extent possible, middle seat in flights should be kept empty.

In this regard, Dutta said the airline would keep the middle seat empty wherever it can and "where we have to fill the middle seat, we will have the extra protective gown".

To a query about possible hedging of fuel prices, he said it would be a dumb idea and that airlines adjust to ups and downs in fuel prices.

"I can't overemphasise what a dumb idea it will be for an airline to hedge fuel prices. I looked at it from different angles and it is not a good idea... we looked at hedging and we talked about it at the board level and we said no," he noted.
