GSLV-D5 launch cleared for January 2014
Dec 28, 2013

India's rejuvenated indigenous cryogenic engine- fitted GSLV-D5 carrying communication satellite GSAT-14  has been cleared for the launch on January 5, 2014. The refurbished three-stage rocket will put into orbit a communication satellite called GSAT-14. The satellite has been integrated with the rocket.

It is an important mission for the Indian Space Research Organisation (ISRO) for two reasons. First, the vehicle features an indigenous cryogenic engine.

The GSLV flight in April 2010 with an indigenous cryogenic engine failed when the ignition of the fuel booster turbo pump in the engine failed to sustain itself. So ISRO wants to prove a new India-built cryogenic engine in this flight.

Second, this flight has a refurbished rocket after the liquid fuel in the second stage of the vehicle leaked 75 minutes before the lift-off on August 19, 2013 and the launch had to be abandoned. The liquid fuel cascaded down the rocket’s first stage and the four strap-on booster motors surrounding it because the propellant tank in the second stage developed cracks.
