Launch of PSLV-C39 carrying IRNSS-1H series satellite was unsuccessful due to minor problem

SHARE

ISRO’s PSLV-C39/IRNSS-1H Launch fails at last minute after heat shield does not separate.

This failure of the heat shield separation was a relatively minor problem, considering the many successful PSLV missions so far. The PSLV remains one of the most reliable launch vehicles in operation, despite the glitch. India will have to launch another navigation satellite to replace IRNSS-1A.

ISRO chairman A S Kiran Kumar says navigation satellite IRNSS-1H mission from Andhra Pradesh’s Sriharikota was unsuccessful, Isro scientists are conducting a detailed analysis of the mission”

The satellite is, however, in orbit, with the heat shield covering it, PSLV-C39 placed IRNSS-1H, the 8th navsat in the NavIC constellation, into orbit, but the heat shield covering the satellite did not separate to release the satellite.

Tracking Details

The satellite separated inside the heat shield, but could not be deployed because of the malfunctioning of the heat shield. All the stages performed as intended, but something went wrong after the command was given to separate the heat shield.
