Components of Chandrayaan-2 modules manufactured in Bhubaneswar centre

Bhubaneswar: 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 here, 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.

Seven specific assemblies for navigation and inertial momentum of the orbiter and the limbs of the moon rover 'Pragyan' have also been manufactured by the centre.

The Indian Space Research Organisation (ISRO) had earlier said all three modules of the moon mission — Orbiter, Lander (Vikram) and Rover (Pragyan) — were getting ready for the launch and the lander was expected to touch down on the lunar surface early in September.

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.

Noting that CTTC had signed an agreement with ISRO in 2016 for technology transfer and a contract for supply of spacecraft component, Maity said the arrangement had helped it further strengthening its manufacturing capability.

"For the current mission, the CTTC has created 22 varieties of valves for the liquid propulsion system of the launching vehicle to control the fuel while releasing it for combustion," he said.

Recalling that the CTTC had supplied critical hardware items for the GSLV Chandrayaan 1, Maity said the institution had also made high-precision components this time for the cryogenic engine that will be used in the GSLV Mk-III.
