India's ambitious moon landing mission Chandrayaan-2 launch was called off due to a technical snag in the 'Bahubali' rocket on Monday about one hour before it was to blast off.

"It is not possible to make the launch within the launch window. The revised launch schedule will be announced later," an official announced from the Mission Control Centre.

Minutes before making this announcement, the officials put on hold the countdown for less than five minutes.

"The technical snag was noticed. We first have to approach the vehicle to assess the problem. First, we have to empty the fuel loaded in the rocket, then the rocket will be taken back for further investigation," an ISRO official said.
