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 30: An Air India flight from Delhi to Moscow on Saturday had to return midway after the airline's ground team found out that one of the pilots had tested positive for novel coronavirus, officials said.

"When the A320 plane, which did not have any passengers as it was heading to Moscow to bring back stranded Indians under Vande Bharat Mission, had reached Uzbekistan's airspace, our team on ground realised that one of the pilots had tested COVID-positive," senior Air India officials said.

"The flight was immediately asked to return. It came back to Delhi at around 12.30 pm on Saturday," the officials said. The crew has been quarantined. Another plane would be sent to Moscow to bring back the stranded Indians, according to the officials.

Muzaffarpur, Mar 18: Prisoners in the central jail here are working overtime to produce facemasks to prevent the deadly COVID-19 striking. In addition to providing protection to fellow inmates and prison staff, the produce will be shared with nine district and sub jails falling under Muzaffarpur Central Prison as well, Deputy Superintendent of the jail Sunil Kumar Maurya said. From supplications at places of worship to hectic activities at the biggest hospital, this north Bihar district is witnessing invocation of all powers, human and otherwise, to prevent novel coronavirus hitting them.

Although nobody has so far tested positive for the dreaded virus in Bihar, where the state government has imposed a semi-lockdown as a preventive measure, Muzaffarpur which hit the headlines last year for losing close to 200 children to an outbreak of brain fever seems determined not to fall prey to yet another virulent affliction.

On making of facemasks by about 50 prisoners, the Deputy Superintendent of the jail said, "We have had a tradition of producing fabric at the Muzaffarpur Central Jail. An idea was floated why not use the skills acquired for producing masks which are in great demand but in short supply.

The local administration seems impressed with the endeavour of the social outcasts to rise to a global challenge.

"It is a welcome step. Despite all precautions, we never know who is going to catch the infection at which place. The efforts by prisoners to protect themselves and the staff manning their premises is laudable. "Full assistance will be provided to Central Jail authorities in supply of the masks to other prisons," Sub Divisional Magistrate (East) Kundan Kumar said.

A conservative town inhabited by a deeply religious citizenry, Muzaffarpur is also witnessing prayer congregations at temples and mosques in keeping with the tradition here of people of all faiths coming together when faced with a major challenge.

The Garib Nath temple, a renowned shrine devoted to Lord Shiva which attracts devotees from far and wide, is witness to the power of faith trumping the biggest fears as the footfall seems to have increased since the outbreak.

The temples mahant Vinay Pathak says, "faith can move mountains. People come here in search of strength to face a crisis which has caused worldwide scare. We advise the visitors to conduct regular 'havans' at their houses just like we have been performing here. "The smoke emitted by burning of purified offerings cleanses the air and, who knows, could be an antidote as well," Pathak added.

Chanting of 'Mahamrityunjay mantra', which the faith believe to be potent enough to dispel illness and untimely death, is taking place round the clock at the shrine in addition to 'havans', the mahant said.

Just a few yards away stands the Chhata Chowk mosque where large number of devotees appear in skull-caps to offer namaz.

"It is a pandemic threatening to engulf the entire world and dua (prayers) are needed as much as dawa (medicines). May God, who is one, listen to the common wish expressed by humanity in myriad ways," says Imtiaz Ahmed, a devout local resident.

Meanwhile, the health authorities are busy with their own efforts, not leaving prevention and cure to divine intervention.

District Medical Officer Shailesh Kumar Singh says a total of 42 people here who have come from abroad, have been tested but their results have been negative.

"Nonetheless, a five-bed special ward has been set up at the Sadar Hospital, manned by medical staff armed with a special kit comprising medicines and other logistics required for primary care of those with suspected symptoms," he said.

The SKMCH referral hospital, which bore the brunt of last years brain fever epidemic accounting for over 120 deaths is fully geared up to meet the latest challenge.

SKMCH superintendent Sunil Shahi says "we have a 30- ward insulation ward ready. Samples of patients with suspected symptoms are being routinely sent to RMRI, Patna. We appeal to all to remain alert, but avoid panic."
