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, Jan 9: Amazon founder and CEO Jeff Bezos will be visiting India next week and is likely to meet Prime Minister Narendra Modi and officials, besides industry leaders, according to sources.

The top executive will also attend SMBhav – an event focussing on small and medium businesses in India - that is slated for January 15-16 in the capital city.

When contacted, Amazon declined to comment.

Amazon, which has seen significant growth in its business in India, has also witnessed protest from a section of traders in the country who claim that e-commerce giants including Amazon and Walmart-owned Flipkart offer deep discounts and engage in unfair business practices.

Last year, the government had tightened rules for e-commerce marketplaces with foreign investment. These rules barred such platforms from offering products of sellers in which they hold a stake and banned exclusive marketing arrangements among other clauses. Following this, Amazon restructured its joint ventures to ensure compliance.

Bezos is likely to discuss regulatory issues in his meeting with the government officials.

He is also slated to engage with SMBs during the SMBhav event. The event - which will focus on discussions around how technology adoption can enable SMBs in India - is slated to see participation from industry experts, policymakers, solution providers and Amazon leadership.

New Delhi, Feb 17: The Supreme Court said on Monday that people have a fundamental right to protest against a law but the blocking of public roads is a matter of concern and there has to be a balancing factor.

Hearing pleas over the road blocks due to the ongoing protests at Shaheen Bagh against the Citizenship Amendment Act (CAA), a bench comprising Justices S K Kaul and K M Joseph said its concern is about what will happen if people start protesting on roads.

Democracy works on expressing views but there are lines and boundaries for it, the bench said.

It asked senior advocate Sanjay Hegde and advocate Sadhana Ramachandran to talk to Shaheen Bagh protestors and persuade them to move to an alternative site where no public place is blocked.

The matter has been posted for next hearing on February 24.

People have a fundamental right to protest but the thing which is troubling us is the blocking of public roads, the bench said.

Solicitor General Tushar Mehta said Shaheen Bagh protestors should not be given a message that every institution is on its knees trying to persuade them on this issue.

The apex court said that if nothing works, we will leave it to the authorities to deal with the situation.

Protestors have made their made their point and the protests have gone on for quite some time, it said.

Restrictions have been imposed on the Kalindi Kunj-Shaheen Bagh stretch and the Okhla underpass, which were closed on December 15 last year due to the protests against CAA and Register of Citizens.

The top court had earlier said the anti-CAA protesters at Delhi's Shaheen Bagh cannot block public roads and create inconvenience for others.

The apex court was hearing an appeal filed by advocate Amit Sahni, who had approached the Delhi high court seeking directions to the Delhi Police to ensure smooth traffic flow on the Kalindi Kunj-Shaheen Bagh stretch, which was blocked by anti-CAA protesters on December 15.

While dealing with Sahni's plea, the high court had asked local authorities to deal with the situation keeping in mind law and order.

Separately, former BJP MLA Nand Kishore Garg has filed a petition in the apex court seeking directions to the authorities to remove the protestors from Shaheen Bagh.

One of the pleas has sought laying down of comprehensive and exhaustive guidelines relating to outright restrictions for holding protests or agitations leading to obstruction of public place.

In his plea, Garg has said that law enforcement machinery was being "held hostage to the whims and fancies of the protesters" who have blocked vehicular and pedestrian movement from the road connecting Delhi to Noida.

State has the duty to protect fundamental rights of citizen who were continuously being harassed by the blockage of arterial road, it said.

"It is disappointing that the state machinery is muted and a silent spectator to hooliganism and vandalism of the protesters who are threatening the existential efficacy of the democracy and the rule of law and had already taken the law and order situation in their own hand," the plea had said.

In his appeal, Sahni had sought supervision of the situation in Shaheen Bagh, where several women are sitting on protest, by a retired Supreme Court judge or a sitting judge of the Delhi High Court.

Sahni has said in his plea that protests in Shaheen Bagh has inspired similar demonstrations in other cities and to allow it to continue would set a wrong precedent.
