Isro to make new stage for GSLV

The high-level task team constituted to probe the August 19 failure of the Geosynchronous Satellite Launch Vehicle-D5 (GSLV-D5) is yet to submit the final report on the reasons for the glitch, but the Indian Space Research Organisation (Isro) has decided to assemble a new second stage for the rocket.

A senior Isro official, while stating that the exact date for the launch of GSLV-D5 can only be set in November, added that the launcher would be launched into space in December, carrying the GSAT-14.

“Going by the availability of hardware and components, the GSLV assembly and checkout is expected to be completed at the vehicle assembly building by the first week of December,” said a note issued by Isro.

“Although the exact reasons for the leakage in the second stage of the engine, which prevented the launch on August 19, are being probed by the team headed by K Narayanan, it has been decided that a new liquid second stage (GS-2) will be assembled to replace the leaked stage,” said the official.

He added that the process of assembling has begun, and that besides the GS-2, all the four liquid strap-on stages are being replaced with new ones.

Another official, while stating that the team is also inspecting the first stage (solid) and core base shroud, added that if any of the elements are found to be affected, “we will replace even those”.

“The satellite assembly, avionics equipment bay and the cryogenic stage will be preserved, following prescribed practices,” said an official note issued by Isro.
