Story highlights

According to ISRO's initial analysis on launch day, it was caused due to 'a technical anomaly in the cryogenic stage'.

The Indian Space Research Organization(ISRO) has revealed that leakage in a crucial valve connected to the fuel tank eventually led to the failure of the GISAT-1 mission.

On August 12, 2021, the launch of GISAT-1, an earth observations satellite onboard India's GSLV Mk 2 rocket had failed barely 350 seconds after its launch from India's spaceport.

According to ISRO's initial analysis on launch day, it was caused due to "a technical anomaly in the cryogenic stage". However, the Indian space agency has now made public their Failure Analysis Committee(FAC) report and pinpointed the reason for the failure.
