ISRO launched a PSLV Thursday carrying a replacement satellite for the Indian Regional Navigation Satellite System (IRNSS) constellation. The IRNSS-1H satellite launched on schedule from the Second Launch Pad (SLP) at the Satish Dhawan Space Centre at 19:00 local time (13:30 UTC). However, the launch profile was off-nominal and the fairing failed to separate leading to an apparent failure of the mission.
