Fuel leak in cryogenic engine led to Chandrayaan 2 mission call off moments ahead of launch
According to sources with the ISRO, the launch of Chandrayaan 2 moon mission was on Monday aborted due a leak detected with the engine. The scientists have further revealed that it may take upto 10 days to fix the engine leak and that the launch is now likely next month. However, there is no official confirmation on the same.

A technical snag was observed in launch vehicle system at 1 hour before the launch. As a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. Revised launch date will be announced later.

Standing at about 44 metre tall, the 640-tonne rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) is nicknamed 'Bahubali'. Just like the hero in the hit film by the same name lifted a heavy 'lingam', the rocket will carry the 3.8 tonne Chandrayaan-2 spacecraft.
The Rs 978 crore Chandrayaan-2 mission was a prestigious one as it aimed to make India as the fourth nation in the world to land and ride on the moon.
The other three nations that had achieved this feat are Russia, 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, four payloads) and rover Pragyan (27 kg, two payloads).
The GSLV-Mk III with a capacity to carry a 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 cryogenic engine.
To date ISRO has sent up three GSLV-Mk III rockets. The first 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 structural stability.
The second and third GSLV-Mk III's went up on 5.6.2017 and 14.11.2018 carrying communication satellites GSAT-19 (3.1 ton) and GSAT-29 (3.4 ton) respectively.
Interestingly, GSLV-Mk III will be used for India's manned space mission slated in 2022.
India presently has two fully operational rockets -- the Polar Satellite Launch Vehicle (PSLV) and GSLV-Mk II -- with a lift-off mass of 415 ton and a carrying capacity of 2.5 tonnes.
