Inclement weather may delay the September 1 launch of GSLV-F02, carrying sophisticated communication satellite INSAT-4CR, from Sriharikota.

"It is raining heavily at Sriharikota where the Satish Dhawan Space Centre is located and if the present weather continues, the launch may get delayed," Indian Space Research Organisation (ISRO) chairman G Madhavan [Images] Nair said.

The GSLV is scheduled to be launched at 4.30 pm on September 1. Responding to a query on India's unmanned mission to moon, Chandrayan, Nair said, "It is progressing well."
