Polar Satellite Launch Vehicle – C39 was the forty-first flight of the PSLV series of launch vehicles on 31 August 2017. Launched in its XL configuration, the vehicle suffered a rare failure – the first failure after 24 years of operations when the heat shield failed to separate and the payload became trapped inside the heat shield and could not be deployed.
