Launch failures common: Experts

MUMBAI: "Failures are quite common in space flights and are considered more as learning experiences," said National Space Society, Indian chapter, chief Suresh Naik, while referring to Thursday's failure of GSLV mission powered for the first time by an indigenous cryogenic engine. NSS is affiliated to the main American body.

Naik, a former Isro employee, told TOI from Pune years ago even the first rocket flights in the US and Japan powered with cryogenic engines failed. "Though we feel disappointed, there is nothing to feel disheartened about. In space missions this is expected. We do not have the data about the cryogenic rocket engine failures in China and Russia," he said.

Referring to the Thursday's incident, he said the main cryogenic engine ignited which indicated that its performance was satisfactory up to that point. However, the problem started when its vernier thrusters failed to ignite resulting in a loss of controllability. These thrusters provide altitude to the rocket. Since they developed a snag, the rocket began to deviate from its designated trajectory, he said.

"The immediate implication of this failure would be that our programme to launch heavier communication satellites using an indigenous cryogenic engine will be somewhat delayed," Naik said.

During the pre-launch tests, he said, the rocket and satellite are subjected to different types of tough tests. "We do our best to simulate the space environment, but at the end there is always an element of uncertainty because space is a hostile environment," he stated.

Moon Society, Indian chapter, secretary Pradeep Mohandas said it was unfortunate that the mission failed but in any maiden space flight this is something common. The society is recognized by US Moon Society. Space scientist Mayank Vahia of TIFR said: "Isro with its excellent track record will soon bounce back. There are no issues."

it's the first time india lunch with her indigenous cryogenic engine,so it's very normal .i don't know if other 4 countries (U,F,R,J) have the similar experience ,CZ-3C also failed the first lunch in 1996


good luck next time

no lol your scientists are wasting money of poor people

Well if poor people of india dont mind their money being burst up in flames what is your problem brother..??? We want to grow.. grow holisticaly....!!! And that growth doesnt come easily... now every achievement of ISRO will be much more sweeter and fullfilling and a whole new learning experience for all of us.

So Kindly get a life.. pls..!!

This is the senior members reply.... :tup: :china:

Dr. Radhakrishnan said the cryogenic technology, which enabled communication satellites to be put into a geo-synchronous transfer orbit at an altitude of 36,000 km, was a highly complex technology. The GSLV-D3 mission was not successful and “we have to face it,” he said. “We have a long way to go and we will do that in the coming year [by launching GSLV with an indigenous cryogenic engine] … We have to work with dedication and I am sure Team ISRO will do it.”

MUMBAI, April 15 (Xinhua) -- India's first launch of powerful carrier rocket with the homemade cryogenic engine failed on Thursday afternoon, local media reported.

The carrier rocket with the homemade indigenous cryogenic engine, GSLV-D3, blasted off from the Satish Dhawan Space Center in the eastern state of Andhra Pradesh. However, its two small engines could not ignite, causing the scientists at the ground control room receiving no signals, CNN-IBN quoted an official of the Indian Space Research Organizaiton (ISRO) as saying.

The official said the ISRO would launch the carrier rocket with the home-made cryogenic engine within a year.

GSLV-D3, whose development began in the 1990s, is about 49 meters high, and more than 400 tons for its launching weight, could send a satellite into an orbit of approximately 36,000 kilometers above the earth.

At present, only the U.S., Russia, China, Japan and France have mastered the advanced cryogenic engine technology in the carrier rocket.

SRIHARIKOTA, India, April 15 (Xinhua) -- Indian Space Research Organization (ISRO) Thursday suffered a setback when the Geosynchronous Satellite Launch Vehicle (GSLV-D3), which was launched using an Indian-designed and built cryogenic engine for the first time, deviated from its path and thus failed.

"The control was lost as two small cryo engines did not ignite, " ISRO Chairman K. Radhakrishnan said here. "We will put all efforts to ensure that the next flight with the indigenous cryogenic engine takes place within a year."

The rocket deviated from its path and the scientists monitoring the launch said that they did not receive any speed and altitude data from the vehicle.

The rocket had lifted from the ISRO Satish Dhawan Space Center (SDSC) launch pad at Sriharikota island, off the coast of the southeastern state of Andhra Pradesh at 16:27 p.m. local time.

However, the launch was not perfect with the GSLV-D3 failing to send any data after 500 seconds of taking off.

The GSLV-D3 was to put the 2.2-ton communication satellite GSAT- 4 into the geo-transfer orbit (GTO) on Thursday evening.

Till now, ISRO had been using Russian cryogenic engines in its GSLV missions as the United States had forced Moscow not to sell the cryogenic technology to India in 1992 and it took India more than 18 years to develop this cryogenic engine as technology.

I pay tax, Atleast its going to ISRO..... What about your tax? Zardari's pocket??



One of your own brothers posted this about how ''Sincere'' Indians might be......

The thread is just the tip of the ice burg in case of corruption everywhere.

ISRO doesn't have the luxury to spend on failing space programs. Maybe the money would have been better spent on health and education.
The guy who claims such failures are common, well that is true, but only for those who can afford it.

NASA lost 2/5 of it's shuttle fleet. But the fact is, NASA is the space agency of a Developed-first world country while ISRO is NOT.


I hope Pakistan does not get into such race. At most Pakistan might want a spy sat or communications sat, and can work with China.
