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 [1] when the heat shield failed to separate and the payload became trapped inside the heat shield and could not be deployed.
The Solar Orbiter spacecraft is a Sun-pointed, three-axis stabilised platform with a dedicated heat shield to provide protection from the high levels of solar flux near perihelion. The spacecraft provides a stable platform to accommodate the combination of remote-sensing and in situ instrumentation in an electromagnetically clean environment.
[2] [3] [4] The launcher started placing the satellites into polar Sun-synchronous orbits one after another after a flight of 16 minutes and 48 seconds. [ 2 ] [ 5 ] It first ejected the satellite Cartosat-2D at an altitude of approximately 510 kilometres (320 mi), with 97.46 degrees inclination, [ 1 ] followed by the two ISRO nanosatellites INS ...

The rounded shape (blunt body) of a capsule forms a shock wave that keeps most of the heat away from the heat shield, but a thermal protection system is still necessary. The space capsule must be strong enough to withstand reentry forces such as drag , and must reenter at a precise angle of attack to prevent a skip off the surface of the ...
