GSLV D5 with indigenous cryogenic engine successfully launched

January 5, 2014
Sriharikota (AP), Jan 5: In a new year gift to the nation, ISRO today successfully launched a Geosynchronous Satellite Launch Vehicle (GSLV D5) with an indigenous cryogenic engine from the spaceport of Satish Dhawan Space Centre here, entering a select club of nations.

With this launch, ISRO became the sixth space agency in the world after US, Russia, Japan, China and France to have tasted success with an indigenous cryogenic engine.

"I am extremely happy and proud to say team ISRO has done it. The Indian cryogenic engine and stage performed as predicted, as expected for this mission and injected precisely the GSAT-14 communication satellite into intended orbit," a jubilant K Radhakrishnan, ISRO chairman said from the Mission Control Room soon after the launch vehicle placed the 1,982 kg GSAT 14 satellite into the intended orbit.

Launching a GSLV with an indigenous cryogenic engine has been a major challenge for ISRO since 2001 after multiple unsuccessful attempts. Only four of earlier seven attempts have succeeded.

GSLV D5's scheduled launch on August 19 last year was called off in the eleventh hour after a fuel leak, following which ISRO moved the vehicle back to the Vehicle Assembly Building and rectified the defect.

Today's launch is India's eighth flight of GSLV and also the fourth developmental flight of GSLV. During this flight, the indigenously developed Cryogenic Upper Stage (CUS) was flight tested for the second time.

GSAT-14 is India's 23rd geostationary communication satellite, as four of GSAT-14’s predecessors were launched by GSLV during 2001, 2003, 2004 and 2007, respectively.

GSAT-14 would join the group of India's nine operational geostationary satellites. The primary objective of this mission is to augment the in-orbit capacity of extended C and Ku-band transponders and provide a platform for new experiments.

The GSAT-14 will be positioned at 74 degree East longitude and co-located with INSAT-3C, INSAT-4CR and KALPANA-1 satellites.

The 12 communication transponders onboard GSAT-14 will further augment the capacity in the INSAT/GSAT system.

ISRO's Cryogenic Upper Stage Project envisaged the design and development of the indigenous Cryogenic Upper Stage to replace the stage procured from Russia and used in GSLV flights, according to ISRO.

ISRO officials had been extremely vigilant in tightening loose ends this time around to avoid an unsuccessful attempt.

Design modifications were implemented wherever required in the launch vehicle along with thorough ground testing and improvements.

The modifications included redesigning of Lower Shroud, which protects the cryogenic engine during atmospheric flight of GSLV-D5 and redesigning of the wire tunnel of the cryo stage to withstand larger forces in flight.

The national space agency also performed two 'Acceptance Tests for flight unit of Fuel Booster Turbo Pump (FBTP), High altitude tests to confirm the ignition sequence in flight under vacuum, to validate design improvements and Cryogenic Main Engine (200 sec) and Steering Engine (100 sec) acceptance tests at Main Engine Test and High Altitude Test.

New Delhi, April 5: People were seen buying diyas and candles across the country to light them at 9 p.m. on Sunday to fight the "darkness of coronavirus" as requested by Prime Minister Narendra Modi.

Although the country is under a lockdown and all the shops barring those selling essential items are shut, but a number of makeshift roadside shops and carts have cropped up selling earthen lamps or diyas at various places.

The earthen lamps, along with other 'puja samgari', are also sold near various temples. Those shops also opened on Sunday.

Gatherings at the temples and other religious places too are barred.
Those who did not find diyas in their localities contended with candles available at the local general stores.

Prime Minister Narendra Modi had on April 3 appealed to people in a televised address to light diyas and candles on April 5 at 9 pm to fight the darkness spread by coronavirus pandemic.

"Friends, amidst the darkness spread by the corona pandemic, we must continuously progress towards light and hope. We must defeat the deep darkness of the crisis by spreading the glory of light in all four directions," said the Prime Minister in a video message.

"And that is why, this Sunday, on April 5, we must all together, challenge the darkness spread by the corona crisis, introducing it to the power of light. On this day, we must awaken the superpower of 130 crore Indians. We must take the super resolve of 130 crore Indians to even greater heights," Modi said.

He asked the people to turn off all the lights in their homes and stand at doors or balconies and light candles or diyas, torches or mobile flashlights for 9 minutes on April 5.

"In that light, in that lustre, in that radiance, let us resolve in our minds that we are not alone, that no one is alone! 130 crore Indians are committed, through a common resolve!" he said.
PM Modi's call to light diyas, torches or mobile flashlights amid the lockdown has proved to be a boon for shopkeepers selling diyas and candles.

"Sales of diyas have increased to 50 per cent and we also got orders. It has happened because of Modi ji's appeal. We are with him in this," Ram Ravi Kumar, a shopkeeper in Delhi told news agency.

Vikas Kumar, a resident of Patna, said, "I have bought 50 diyas for today. PM Modi had said that people have to light the diyas for nine minutes after switching off light at home."
Modi has asked citizens to not assemble anywhere while participating in this programme and emphasised on the importance of social distancing to prevent coronavirus spread.

Meanwhile, the number of positive cases of coronavirus in the country continues to surge. As per the Ministry of Health and Family Welfare, the total number of confirmed COVID-19 cases is 3,374 with 79 deaths.

Kochi, Apr 16: A middle-aged man carrying his ailing father on his shoulders walked close to one-kilometre in Kerala’s Punalur when the autorickshaw he was driving was allegedly stopped by the police over the ongoing lockdown. He was bringing back his father from the hospital after he was discharged on Wednesday.

In a video that has gone viral on social media, the man can be seen carrying his bare-bodied father on the shoulders and struggling to handle the weight while a woman carrying the hospital documents, prescriptions and other items, is running along with him.

The incident took place in Punalur town of Kollam district.

The 65-year-old man, a native of Kulathupuzha, was released from the Punalur Taluk Hospital and his son was taking him home when he was stopped on the road. The man has alleged that even after he produced hospital documents, the police refused to let him pass with the autorickshaw.

The vehicle was stopped about a kilometre from their house in the middle of a traffic jam and the family had to walk the rest of the path. He said even after he told the police and showed papers from hospital he was not allowed to go.

After the video went viral in Kerala, the state human rights commission took suo motu cognizance of the incident.

The nationwide lockdown has prevented all non-essential movement in the public space while medical emergencies have been allowed. The extended lockdown will now continue till May 3.

According to the police, the vehicle did not have the patient when it was stopped. The driver was asked to show a declaration document.

He stepped out of the vehicle and walked to the hospital which was 200 metres from the checkpoint and returned carrying his father on the back, said the police.
