Isro's IRNSS-1H mission unsuccessful as heat shield fails to separate

This is country's first satellite built by private firms

Indian Space Research Organsiation's (Isro) attempt to launch India's eighth navigation satellite IRNSS-1H failed today. While the rocket took off successfully, the heat shield did not separate as planned due to which satellite could not be put in orbit. This is the first failure in 35 launches for Isro's workhorse  Polar Satellite Launch Vehicle PSLV.

Since heat shield did not open on PSLV-C39, satellite got trapped, thus making the launch unsuccessful.

After the 29-hour countdown, Polar Satellite Launch Vehicle (PSLV-C39) carrying the 1425-kg navigation satellite IRNSS-1H blasted off from the second launch pad at Sriharikota in Andhra Pradesh
