Nellore: The launch of Chandrayaan-2 was put off at the eleventh hour early on Monday morning after a snag detected which was causing a gradual drop in the high-pressure helium bottles where were to operate the valves of the cryogenic upper stage.
The revised launch date will be announced later, he added.
It is expected that the process of investigating the technical snag may take around 10 days.
Earlier this year, when the Chandrayaan-2 launch dates were announced, Isro chairman Dr K. Sivan had said that the launch window - the time period within which space missions must be launched - would end on July 16.
The next opportunity may arise on July 29 or 30. If the spacecraft is not ready by then, the next launch window opens only a few months later, sources in the Isro said.
