"The launch of the GSLV-D5 scheduled for 1650 hrs today (August 19, 2013) is called off, as a leak is observed in the UH25 fuel system of the liquid second stage during the pre-launch pressurisation phase on the vehicle just two hours before the scheduled lift-off," the Indian Space Research Organisation (ISRO) said in a statement.
The vehicle, which was scheduled to put a new communications satellite into orbit, will be moved back to the Vehicle Assembly Building for further actions.
"The propellants are being drained from the Cryogenic Stage, Liquid Second Stage and the four liquid Strap-ons of GSLV-D5. The vehicle will be moved back to the Vehicle Assembly Building for further actions," the statement said.
The ISRO said that a revised launch date will be announced after a detailed assessment.
The rocket has reportedly cost India Rs. 160 crore, while the satellite's price tag is Rs. 45 crore, thereby making the mission to cost over Rs. 200 crore.
