Indian Union Minister of State (Independent Charge) for Ministry of Science and Technology, M/o Earth Sciences, D/o Atomic Energy and D/o Space Jitendra Singh on Wednesday said the GSLV project has successfully launched GSLV-D5 flight with indigenous Cryogenic engine and stage on Jan 5 from Satish Dhawan Space Centre, Sriharikota and is currently preparing for the next flight GSLV namely, GSLV-D6.

“The GSLV-F02, GSLV-D3 and GSLV-F06 flights could not accomplish the mission objectives. Subsequently, failure analysis committees were formed to (a) carry out in-depth analysis of the flight performance and identify causes for the failure, and (b) recommend corrective measures and future course of action on the GSLV Vehicle. The failure analysis committees have submitted their recommendations,” Singh said in a reply to a written question in the Lok Saha on Wednesday.

He said, “Based on the suggestions made by the failure analysis committees, ISRO has implemented the modifications and improvements in GSLV, which include independent inspection and quality checks for all critical components and sub-assemblies, change of bearing housing material, revision of tolerances and seal clearances of Fuel Booster Turbo Pump of Cryogenic Engine, redesign of the Cryogenic Stage Lower Shroud, revision of connector mounting scheme and wire tunnel configuration.”
