The Indian Space and Research Organisation (ISRO) has rectified the fault in its Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) whose Monday flight with Chandrayaan-2 spacecraft was called off one hour before its lift-off.
While there is no official word about the status of the rocket since the flight was called off due to a technical snag, it is learned from officials of ISRO that the glitch has been rectified. “Couple of dates are being looked at for the rocket’s launch. It could be between July 20-23,” an official said.

One hour before the lift-off officials detected a snag and called off the mission.
“A technical snag was observed in launch vehicle system at one hour before the launch. As a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. The revised launch date will be announced later,” ISRO tweeted and didn’t elaborate further. The rectification process later revealed a fault in the helium gas bottle in the cryogenic engine, which in turn failed to build pressure due to a leak in the ‘nipple joint’ of the spacecraft.
