ViruRulez Posted April 15, 2010 Posted April 15, 2010 Sriharikota: Scientists were on Thursday getting ready to launch an Indian-designed and built cryogenic engine to inject an advanced communication satellite into space. The filling of liquid fuel that will power the third stage of the 50-metre tall, 416-tonne Indian rocket to inject the satellite in geo-synchronous orbit is expected to start around 11.30 am. The filling super cooled liquid hydrogen as fuel and liquid oxygen (oxidiser) for the cryogenic engine (12.5 tonnes) will continue minutes before the rocket blasts off from the second launch pad at the spaceport, around 80 km from here. The rocket, Geosynchronous Satellite Launch Vehicle (GSLV-D3), is slated to inject GSAT-4, an advanced communication satellite into geo transfer orbit (GTO) on Thursday evening. "Preparations for fuelling the cryo engine is going on. Filling of liquid propellants in the second stage (40 tonnes) and the four strap-on motors (42 tonnes each) that will be hugging the rocket are over," Indian Space Research Organisation (ISRO) director S Satish. ISRO officials are confident of a smooth and successful launch, he said. The countdown for the blast off for the Rs.330 crore mission (rocket Rs 180 crore, GSAT-4 satellite Rs 150 crore) started on Wednesday at 11.27 a.m. The first stage with 138 tonnes solid fuel is all ready to be fired up. The rocket is expected to blast off at 4.27 pm on Thursday to deliver the 2.2-tonne GSAT-4 satellite into GTO. Queried about the Rs 20 crore cost increase for the rocket, the earlier one cost around Rs.160 crore in 2007, Satish said: "Compared to the previous GSLV rockets this is taller by one metre and weighs two tonnes more. The rocket has a bigger heat shield. One also has to factor the cost escalation aspects over the years." The notable aspect of this launch is that the rocket will be powered by ISRO-designed and built cryogenic engine (development cost around Rs 350 crore). If the cryogenic engine performs as expected, India will become the sixth country in the world to design and develop the cryogenic technology. The two other unique features of the rocket are its larger composite payload fairing or heat shield and the advanced telemetry systems and mission computers. After a gap of several decades, the Indian space agency has reverted to fibre reinforced plastic (FRP) heat shield for its rocket. The GSLV-D3 rocket has a bigger heat shield - four metre diameter - as compared to the earlier rocket versions whose heat shield were of 3.4 metre diameter and were made of aluminium alloy metal. http://ibnlive.in.com/news/isro-to-launch-first-cryogenic-engine/113355-11.html?from=tn The launch will take place in the next 10-15 minutes .. the other countries which have the indigenous cryogenic technology right now are US, Russia, European Space Agency, China and Japan. :isalute:
ViruRulez Posted April 15, 2010 Author Posted April 15, 2010 The news channels are showing it live.. watch it guys .... only 1 or 2 minutes left
ViruRulez Posted April 15, 2010 Author Posted April 15, 2010 First stage successful now .. rocket goes into second stage :isalute:
ViruRulez Posted April 15, 2010 Author Posted April 15, 2010 feck the **** .. there is now a bit of deviation from the expected rocket path in the cryogenic stage :nervous:
ViruRulez Posted April 15, 2010 Author Posted April 15, 2010 The launch seems to have failed .. they dont have any data and contact with the rocket/satellite now .. for now it seems failed .. they are trying to retrieve it but as of now it seems to have failed :((
meloveindia Posted April 15, 2010 Posted April 15, 2010 mission failed, hopefully better luck next time
ViruRulez Posted April 15, 2010 Author Posted April 15, 2010 yes mission failure Meanwhile ISRO has announced right now that within 1 year they will again launch a satellite with the indigenous cryogenic engine .. we had been working on it for 18 years and now it will be one more year .. anyways good try and hopefully we will join the 5 nation club next year :isalute:
Ram Posted April 15, 2010 Posted April 15, 2010 The guys over at the ISRO must feel absolutely crushed by now..
ViruRulez Posted April 15, 2010 Author Posted April 15, 2010 Experts are saying that US and Japan also had failed in their first cryogenic test .. Russia and China (being communist nations) only informed the world after they were successful and so we dont know if they failed or were successful the first time .. France is the only country which for sure were successful in launching using their indigenous cryogenic technology the first time itself ... so maybe it is not that bad :D Anyways ISRO has one of the most successful rate of launches in the world and they are doing a great job. No problem next year kar lenge. :cheer:
Asim Posted April 15, 2010 Posted April 15, 2010 Failed and disconnected from control room after 505 second... Better luck, Next time...!!!
urbestfriend Posted April 15, 2010 Posted April 15, 2010 This is shitz man....Why ISRO scientists can't simulate this properly...! It looks like they test their products live and more often it'll fail...!

It looks like they test their products live and more often it'll fail...! ISRO has one of the best success rates in the world .. more often than other countries it succeeds but space programs fails all over the world sometimes .. it is not unusual
zubinpepsi Posted April 15, 2010 Posted April 15, 2010 I shouldn't laugh' date=' but :haha:[/quote'] :haha::haha: sorry thts in poor taste dopey..
Sachinism Posted April 15, 2010 Posted April 15, 2010 :haha::haha: sorry thts in poor taste dopey.. I'm not laughing at them failing, but the change in Virurulez emotions after every post
