The Indian Space Research Organisation (ISRO) says the aborted lift-off of the Geostationary Satellite Launch Vehicle (GSLV) was caused by loss of thrust in one of the four Vikas-powered liquid propellant strap-on stages which ignited at T-4.6s.

By T-1s, before the ignition of the central solid-propellant core stage, the launch computer recorded the lack of thrust and stopped the count. The Vikas engine is already used to power the second stage of the operational Polar Satellite Launch Vehicle (PSLV).

The GSLV also uses the Vikas engine to power its second stage, while the third stage is a modified Russian engine from the Proton fourth stage. The programme has been delayed indefinitely.
