Mission Director has authorised Vehicle Director for launch. Automatic Launch Sequence (ALS) program initiation authorised by Vechicle Director and ALS started for launch of PSLV-C39/IRNSS-1H Satellite mission at 18:47 hr IST.

The forty first flight of India’s Polar Satellite Launch Vehicle (PSLV-C39), conducted today (August 31, 2017) evening from Satish Dhawan Space Centre SHAR, Sriharikota, was unsuccessful.  PSLV-C39 had a normal lift-off at 1900 hrs IST (7:00 pm) and all the flight events took place exactly as planned, except heat shield separation.

This resulted in satellite separation occurring within the heat shield.  The satellite is inside the heat shield resulting in the unsuccessful mission. Detailed analysis is under progress to identify the cause of the anomaly in the heat shield separation event.

The Polar Satellite Launch Vehicle, in its forty-first flight (PSLV-C39), will launch IRNSS-1H, the eighth satellite of the Indian Regional Navigation Satellite System (IRNSS) into a Sub-Geosynchronous Transfer Orbit (Sub-GTO). The launch will take place from the Second Launch Pad (SLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. As in the previous six launches of IRNSS satellites, PSLV-C39 will use ‘XL’ version of PSLV equipped with six strap-ons, each carrying 12 tons of propellant.
