Isro's IRNSS-1H launch unsuccessful: 10 things to know about the mission

Thursday's failure is the first for the PSLV since 1994 when the rocket became operational

 

The Indian Space Research Organisation's (Isro's) mission on Thursday to launch the IRNSS-1H, India's eighth navigation satellite, from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh, on board its workhorse PSLV launch vehicle failed as the heat shield separation did not take place and the satellite got trapped within the shield. 

However, the failure is not expected to affect the navigation satellite network since the system can function with four efficient satellites. At present, the network has six functional satellites in orbit, according to sources.
