Chandrayaan-2 Moon Mission Launch HIGHLIGHTS Updates: India’s second mission to Moon, Chandrayaan-2 onboard GSLV MKIII was called off due to a technical snag on Monday, the Indian Space Research Organisation (ISRO) said.

“A technical snag was observed in launch vehicle system at T-56 minute. As a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. Revised launch date will be announced later,” the ISRO tweeted. The countdown was held back with 56.24 minutes to go for the launch.

“A new launch date will be announced later,” ISRO added. It was not clear how soon the new launch date could be.

With Chandrayaan-2, India will become the fourth country to land a spacecraft on the moon. Chandrayaan 2 mission is aimed at exploring the south pole of the Moon, which holds maximum promise for the presence of water as well as fossil footprints.

“Chandrayaan 2 is the next leap in technology as we attempt to soft-land close to South Pole of Moon. The soft landing is extremely complex and we will experience approximately 15 minutes of terror,” ISRO chief K Sivan said.

ISRO’s first successful moon mission, Chandrayaan-1, was launched on October 22, 2008. It was an orbital drone that revolved around the moon and an impactor landed on its lunar surface.

Components of Chandrayaan-2 modules manufactured in Bhubaneswar centre

Important components of the modules of India's ambitious second lunar mission, Chandrayaan-2, to be launched on Monday, have been manufactured by a Union government-run centre in Bhubaneswar, an official said on Sunday.

The Central Tool Room and Training Centre (CTTC) has manufactured 22 types of valves for fuel injection and other parts for the cryogenic engine of the Geosynchronous Satellite Launch Vehicle (GSLV) Mark III rocket, dubbed "fat boy" by Indian scientists for its ability to carry satellites weighing up to 4 tonnes, a top official said.

The Bhubaneswar-based institution had started manufacturing the parts for the country's prestigious lunar mission in March 2017, the centre's Managing Director Sibasis Maity, told PTI in an interview. (PTI)

The rocket is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tons to Low Earth Orbit (LEO).

Doordarshan (DD) has the official rights to stream the event live on its TV channel, along with commentary and visuals from both the launch pad and ISRO’s mission control room.

Once launched into an earth parking 170 x40400 km orbit, a series of maneuvers will be carried out to raise its orbit and put Chandrayaan-2 on Lunar Transfer Trajectory. “On entering moon’s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. The Orbit of Chandrayaan-2 around the moon will be circularised to 100×100 km orbit through a series of orbital maneuvers,” ISRO says.
