PSLV-C39 mission failed after launch | IRNSS-1H satellite

 IRNSS-1H satellite

On August 31 2017 ISRO launched the IRNSS-1H into orbit using the PSLV C39 rocket from the Satish Dhawan Space Centre the Sriharikota High Altitude Range (SHAR) in Andhra Pradesh, but failed. The PSLV-C39 managed to deliver the IRNSS-1H satellite to elliptical Sub-Geosynchronous Transfer Orbit in space but that the heat shield on PSLV-C39 could not open and hence the satellite could not be released the resulting in the unsuccessful mission. While the exact reasons for this failure is will be known after an investigation, which will soon be conducted by a committee of experts which is said by ISRO chairman A S Kiran Kumar.

This is only second time in the history that the PSLV had failed. First failure was on September 20, 1993, the PSLV-D1 was supposed to launch IRS-1E, a remote sensing satellite. The PSLV has played a key role in ISRO's success over the years. Since the 1993, Different versions of PSLV has had 39 successful launches, including putting into space 104 satellites in one go earlier this year.

Before three months back on Jun 23, 2017 ISRO launched PSLV-C38, it can put 31 satellites includes earth observation satellite Cartosat-2s and other 30 Nano satellites in the orbit successfully.
