Failure of pyro or fuel systems resulted in India losing rocket and satellite

Failure of the ignitor or failure of the cryogenic engine to get ignited or even the failure of the avionics in sending the ignite signal is contemplated as the reasons for Indian rocket going down on Thursday early morningThey also said the rocket systems could have failed as it was kept idle for over a year due to technical and also due to the spread of Covid19 pandemicIndias Geosynchronous Satellite Launch VehicleF10 GSLVF10 carrying the countrys first GeoImaging Satellite GISAT1 lifted off from the spaceport in Sriharikota in Andhra PradeshThe failure resulted in the loss of rocket and satellite both valued over several hundred crores of rupees and also the revenue opportunity for 10 yearsAlso read GSLVF10EOS03 mission could not be accomplished due to performance anomaly in cryogenic stage ISROThe GISAT1EOS03 with a life span of 10 years would have been the countrys first eye in the sky or earth observation satellite to be placed in geostationary orbitThe Indian Space Research Organisation ISRO in a statement after the rockets failure said GSLVF10 launch took place on August 12 2021 at 0543 Hrs IST as scheduled Performance of first and second stages was normal However Cryogenic Upper Stage ignition did not happen due to technical anomaly The mission couldnt be accomplished as intendedWhat is that technical anomaly is the moot question The cryogenic engine is a complex system and the failure is not due to design flaw former Chairman of Indian Space Research Organisation ISRO G Madhavan Nair told IANSAccording to him the ignitorpyro systems could have ignited but the fuel might not have due to various reasonsNair also agreed the rocket being kept idle for more than a year after it was readied for flight could have also affected the functionality of the componentsIt could be a failure in avionics in sending the ignite signal Or the failure of igniter which is a pyro element where testing is done for few in a batch rather than every component Moreover there is long storage of components due to pandemic delay causing some unnoticed component failure in the ignition system another space sector official on the condition of anonymity told IANSCryo stage did not ignite is the cause this is officially announced and can be seen in the curve the official addedOriginally the GISAT1EOS03 was slated for launch on March 5 2020 but hours before the launch ISRO announced postponement of the mission owing to some technical glitchSoon after the Covid19 pandemic and the lockdown delayed the mission The rocket had to be dismantled and cleaned upSubsequently the GISAT1EOS03 launch was slated for March 2021 but due to problems in the satellites battery side the flight got delayed againWith the replacement of the battery the satellite and the rocket were being readied for their flight at Sriharikota when the second wave of Covid19 swept in affecting many at the rocket launch centreAnother space sector expert preferring anonymity told IANS On seeing the videos captured by the cameras fixed at the rocket one can conclude as to the cause of lossDuring launch ISRO did announce separation of the heat shield shutting off of the second stage and firing of the cryogenic stage Success of cryo ignition and normal thrust was announced the expert saidI would not be surprised that the heat shield did not get separated though telemetry may be correct and the vehicle veers out of trajectory due to excess load of heat shield apart from the satellite load he addedNon separation of heat shield even with four way redundancy and yet sending right telemetry has been seen earlier This phenomenon was seen in PSLV 39 launch with IRNSS1H on 31st August 2017 But due to the presence of an on board camera the non separation of the heat shield was detected Otherwise it could have been passed off as malfunctioning of the last stage of the rocket the expert remarkedHowever Nair does not agree with this possibilityAfter the separation of the heat shield the rocket had travelled for several seconds on the plotted path Had the heat shield not separated then the rocket would have veered away much earlier Nair saidAccording to him detailed flight data will be available a couple of days later The reasons for nonfiring of the cryogenic engine will have to be probed by ISRO if a faulty component was the reasonEarlier in a GSLV rocket that went up a component with higher dimension than what was designed was fixed and the rocket failed The Indian space agency does not insure its rockets and satellites launched from the countryIronically Thursdays failure comes on the birth anniversary of Vikram Sarabhai the father of Indias space sector The 5710 metre tall 416 tonne GSLVF10 lifted off from the second launch pad at 543 amWith a strong deep growl rose into the sky breaking free from the second launch pad here at the Satish Dhawan Space Centre The GSLVF10 is a three stageengine rocket The core of the first stage is fired with solid fuel and the four strapon motors by liquid fuel The second is the liquid fuel and the third is the cryogenic engineEverything went well as planned till the cryogenic engine got into picture at about five minutes into the rockets flight The ISRO had also announced the commencementignition of the cryogenic engineJust over five minutes into the rockets flight the mission control centre at the spaceport here tensed up The rocket was seen on the telemetry screen veering away from its plotted path There was no data coming from the rocket Experts said the rocket and the satellite would have burnt in the atmosphere while falling downThis story has been sourced from a third party syndicated feed agencies Midday accepts no responsibility or liability for its dependability trustworthiness
