India’s ambitious moon landing mission Chandrayaan-2 launchwas called off due to technical snag in the ‘Bahubali’ rocket on Monday aboutone hour before it was to blast-off.
“It is not possible to make the launch within thelaunch window. The revised launch schedule will be announced later,” anofficial announced from the Mission Control Centre.
Minutes before making this announcement, the officials puton hold the countdown for less than five minutes.
“The technical snag was noticed. We first have toapproach the vehicle to assess the problem. First we have to empty the fuelloaded in the rocket, then the rocket will be taken back for furtherinvestigation,” an ISRO official told IANS.
“This process will take 10 days after that only we candecide on the launch schedule,” he added.
The launch was called off nearly one hour before the actualtime of launch which was 2.51 a.m.
“A technical snag was observed in launch vehicle systemat T-56 minute. As a measure of abundant precaution, #Chandrayaan2 launch hasbeen called off for today. Revised launch date will be announced later,”ISRO tweeted later.
Standing at about 44 metre tall, the 640-tonne rocketGeosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) is nicknamed’Bahubali’. And just like the hero in the hit film by the same name lifted aheavy ‘lingam’, the rocket will carry the 3.8 tonne Chandrayaan-2 spacecraft.
The Rs 978 crore Chandrayaan-2 mission was prestigious oneas it aimed to make India as the fourth nation in the world to land and ride onthe moon.
The other three nations that had achieved this feat areRussia, the US and China.
The Chandrayaan-2 consists of three segments – the Orbiter(weighing 2,379 kg, eight payloads), the lander-Vikram (1,471 kg, fourpayloads) and rover Pragyan (27 kg, two payloads).
The GSLV-Mk III with a capacity to carry four ton satellite,is a three stage/engine rocket with two strap-on motors powered by solid fuel.The second stage is a core liquid fuel booster and the third is the cryogenicengine.
To date ISRO has sent up three GSLV-Mk III rockets. Thefirst one was on 18.12.2014 carrying Crew Module Atmospheric Reentry Experiment(3.7 ton). The mission was also to test the rocket’s inflight structuralstability.
The second and third GSLV-Mk III’s went up on 5.6.2017 and14.11.2018 carrying communication satellites GSAT-19 (3.1 ton) and GSAT-29 (3.4ton) respectively.
Interestingly, GSLV-Mk III will be used for India’s mannedspace mission slated in 2022.
India presently has two fully operational rockets — thePolar Satellite Launch Vehicle (PSLV) and GSLV-Mk II — with a lift-off mass of415 ton and a carrying capacity of 2.5 tonnes.
