The technical snag was noticed during the cryogenic fuel was being loaded. We 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. This process will take 10 days after that only we can decide on the launch schedule.
