Lack of fuel supply led to GSLV-D3 failure

Seizure of rotor or rupture of the turbine casing could be the probable cause for the failure of the indigenous cryogenic engine that led the Geosynchronous Satellite Launch Vehicle (GSLV-D3) crash into the sea this April, says an expert committee.

GSLV-D3 Failure Analysis Report

The third developmental flight of Geosynchronous Satellite Launch Vehicle (GSLV-D3) conducted on April 15, 2010 from Satish Dhawan Space Centre SHAR, Sriharikota, primarily for the flight testing of indigenously developed Cryogenic Upper Stage (CUS), could not accomplish the mission objectives. Consequently, ISRO had instituted a two-tier process to carry out an in-depth analysis of the flight performance, identify the causes of failure and recommend corrective measures.

ISRO to re-launch GSLV in one year

The Indian Space Research Organisation (ISRO) is planning to relaunch the Geosynchronous Satellite Launch Vehicle (GSLV) with a home-grown cryogenic engine in a year's time after the failure in April this year.

Amid the din of big rockets and cryogenics, a small but very significant step into space, which plunged into the sea along with the GSat-4 satellite, went completely unnoticed.
Even its mention in the brochures and other publicity literature was so unobtrusive and couched in jargon that perhaps an enthusiast would probably have glossed over its significance.
We are speaking of the 'plasma thrusters'.

ISRO: GSLV D3 launch partial failure

India's GSLV-D3 powered by home-grown cryogenic engine for the first time failed in its mission as the rocket carrying a communication satellite deviated on Thursday (April 15) from its path and went out of control shortly after its lift-off from the spaceport in Sriharikota, Andhra Pradesh.

India's cryogenic launch fails

India's bid to launch an advanced communications satellite into orbit for the first time by using a cryogenic engine has failed, scientists say.
The rocket took off as planned but the phase powered by the new engine failed to perform and deviated from its path.
Cryogenic engines are rocket motors designed for fuels that have to be held at very low temperatures to be liquid. They would otherwise be gas.
