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.

Precisely 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.

Congress leader Sam Pitroda has stepped down from the post of Chairman of the Indian Overseas Congress and his resignation was accepted by the party. Congress leader Jairam Ramesh took to X and announced that Sam Pitroda had decided to resign from the key post "of his own accord".

Pitroda had been under fire over his controversial remark that Indians in the East resemble the Chinese while those in the South look like Africans.

"We could hold together a country as diverse as India -- where people on East look like Chinese, people on West look like Arab, people on North look like maybe White and people in South look like Africans. It doesn't matter. We are all brothers and sisters," Pitroda said during an interview with The Statesman.

The Congress immediately distanced itself from Pitroda's remarks, terming them "unacceptable".

"The analogies drawn by Mr Sam Pitroda in a podcast to illustrate India's diversity are most unfortunate and unacceptable. The Indian National Congress completely dissociates itself from these analogies," Jairam Ramesh said in a post on X.

The BJP also hit out at the Congress over Pitroda's remarks and termed them "racist and divisive".

Maharashtra Leader of Opposition Vijay Namdevrao Wadettiwar waded into controversy after he alleged that an RSS-affiliated cop, and not terrorist Ajmal Kasab, killed former state anti-terrorism squad (ATS) chief Hemant Karkare during the 26/11 Mumbai terror attack.

In a video statement released on Saturday, the Congress leader alleged that the bullet that killed IPS officer Hemant Karkare did not come from the gun of Ajmal Kasab or any of the other nine Pakistani terrorists involved in the attacks.

Instead, he claimed it came from the weapon of a police officer allegedly "dedicated to" the Rashtriya Swayamsevak Sangh (RSS).

Wadettiwar also accused Ujjwal Nikam, the special public prosecutor in the case and a BJP Lok Sabha candidate from Mumbai North Central, of suppressing this information, labeling him a "traitor."

He questioned the BJP's decision to nominate Nikam for the Lok Sabha polls, accusing the party of protecting traitors.

“During the probe, key information was out. However, it was suppressed by Ujjwal Nikam, who is a traitor. My question is, why is BJP protecting a traitor and nominating such a person for Lok Sabha polls? By doing this, BJP is protecting traitors," Wadettiwar alleged, Times of India reported.

These allegations drew strong responses from Nikam and Deputy Chief Minister Devendra Fadnavis.

Nikam condemned Wadettiwar's statement as "baseless and irresponsible," expressing pain at the doubts raised over his integrity.

He emphasized the legal steps taken to convict Kasab, calling Wadettiwar's remarks an insult to the victims of the 26/11 attacks.

“What a reckless statement is being made. I am pained by such baseless allegations, raising doubts over my integrity. It clearly reflects the level of electoral politics. I never thought politicians will stoop to such low levels. For political gain? He (Wadettiwar) is insulting not me, but the 166 departed souls and all persons injured in the 26/11 attacks," Nikam said.

He added, “They (Congress) hold Kasab as innocent. Even Pakistan had accepted that Kasab was involved in the conspiracy and in the terror attack on India and was guilty".

He said Indians very well know the legal steps he had taken to ensure Kasab’s conviction.

Nikam said citizens of the nation would on 4 June, the day of results for Lok Sabha polls, give their reply to such allegations, adding he wished not to dignify the “desperate disinformation” with a further response.

Meanwhile, BJP leader and Deputy CM Fadnavis said, “Our alliance is with Nikam, while Congress has joined hands with Kasab".

Shiv Sena spokesperson Kiran Pawaskar said NIA should arrest Wadettiwar and ask him why he was defending Kasab.

Pawaskar criticized the Congress for allegedly supporting terrorists and expressed surprise at the silence of Shiv Sena chief Uddhav Thackeray on the matter.

“From Wadettiwar’s statement, it appears Congress is supporting terrorists who attacked Mumbai. More shocking is the fact that Sena (UBT) chief Uddhav Thackeray has maintained silence over the episode,” he said.

New Delhi: In fresh claim, Prime Minister Narendra Modi on Friday said that his government sent an envoy to Israel urging them to stop the airstrike in Gaza during Ramadan. He said that he urged Israel to maintain peace rather than engage in combat during the holy month.

In an interview with Aaj Tak, PM Modi said that his envoy told Israel they should not bomb Gaza, at least during the auspicious month of Ramadan.

"During the month of Ramadan, I sent my special envoy to Israel to meet and explain to Prime Minister (Benjamin Netanyahu) that he should not carry out bombings in Gaza during Ramadan. They made every effort to follow it, but in the end, there was a fight for 2-3 days," he said.

The Prime Minister said that he does not publicise such things even though people in India keep "cornering him on the Muslims issue".

PM Modi said that some other countries also tried to speak to Israel to halt the bombings and may have also achieved results.

"They may have got the results too. I also tried," he said.

During the interview, PM Modi also said that he made standalone visits to both Israel and Palestine, unlike earlier governments which used to display token secularism.

"There was a fashion earlier that if one has to go to Israel, a visit to Palestine is a must. Do secularism and come back. But I refused to do it," he said.

The Prime Minister also recounted an episode when he needed to travel to Palestine via Jordan.

"When the President of Jordan, who is a direct descendent of Prophet Muhammad, came to know that I am going to Palestine over (the airspace of Jordan), he told me 'Modi ji, you cannot go like this. You are my guest and will use my helicopter'," Modi claimed.

Describing the unique amalgamation of circumstances, he continued, "I went to his home for dinner, but the helicopter was of Jordan, the destination was Palestine, and I was escorted by Israeli flight attendants. All three are different but for Modi, all came together in the sky."
