On May 2025, the third output of the Indian Space Research Organization (ISRO) BSLV rocket failed. ISRO leader Dr V Narayanan said there was a problem in the third stage of the rocket. Its investigation has been launched.

What happened?

The third stage of the PSLV rocket has a solid motor, covered with a strong cover called Kevler. ISRO suspects that this cover erupted. Also, the Flex tip came into a mistake in the third stage (which controls the direction of the rocket). The cover eruption and the node malfunction may be interconnected.
