Insufficient Pressure Conditions in Fuel Tank Led to the Failure of GSLV Mission in 2021: ISRO
The Indian rocket that carried the country's first Geo Imaging Satellite (GISAT-1) failed in its mission, owing to damage in the soft seal in a critical valve which resulted in lower pressure in the rocket's liquid hydrogen (LH2) tank, the Indian Space Research Organization (ISRO) said on Friday. According to ISRO’s Failure Analysis Committee (FAC), the failure happened when the Geosynchronous Satellite Launch Vehicle (GSLV) rocket's cryogenic engine was to take the rocket forward. (The GSLV-F10 is a three-stage/engine rocket. The core of the first stage is fired with solid fuel and the four strap-on motors by liquid fuel. The second is the liquid fuel and the third is the cryogenic engine.)
