ISRO Has Stepped Up The “Robustness” Of Its Launch Vehicle

The Indian space agency has stepped up the “robustness” of its Polar Satellite Launch Vehicle (PSLV) scheduled to go up next month, a senior official said The move by the Indian Space Research Organisation (ISRO) comes after the non-separation of the heat shield of the PSLV-XL rocket that was launched on Aug 31, 2017, resulting in failure of the mission. “We are not tense about the upcoming December rocket launch after the failure of the previous mission. While the study as to the cause of failure of the earlier rocket is on, we have increased the robustness of the next rocket,” K. Sivan, Director, Vikram Sarabhai Space Centre, told.

As a result of the failure, the navigation satellite IRNSS-1H could not be put into orbit. The satellite was a substitute for IRNSS-1A that is facing some technical problems. The Indian space agency will be launching its Cartosat cartography satellite next month, along with 30 small satellites, Sivan said. ISRO is also further tightening the allowable dispersion, or variance from the ideal performance parameter, for all the systems in its next PSLV. He said the failure in August was not due to a design fault. Sivan said the failure of the pyro elements could be the reason for the non-separation of the heat shield.
