GSAT-4 also known as HealthSat was an experimental communication and navigation satellite launched in April 2010 by the Indian Space Research Organisation on the maiden flight of the Geosynchronous Satellite Launch Vehicle Mk.II rocket. It failed to reach orbit after the rocket’s third stage malfunctioned. The third stage was the first Indian-built cryogenic-fuelled upper stage and was making its first flight. The ISRO suspects that the failure was caused by the third stage not igniting.
