India’s space agency has decided to completely replace the second stage of the GSLV rocket that leaked during the rocket’s scrubbed launch last month.

“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.

That leak must have been quite significant for them to make this decision.

Engineers in India have decided to completely replace the leaking second stage engine of the GSLV rocket whose launch was scrubbed last week.

Engineers in India have decided to completely replace the leaking second stage engine of the GSLV rocket whose launch was scrubbed last week.

The GSLV is a three-stage launch vehicle with four strap-on motors hugging the first stage. The first stage is powered by solid fuel while the four strap-on motors and the second stage are powered by liquid fuel. The third is the cryogenic engine powered by liquid hydrogen and liquid oxygen.

“At the rocket assembly building, the satellite, cryogenic engine and the second stage have been destacked. It has been decided to shift the second stage to Mahendragiri for detailed inspection and study,” the ISRO official told IANS. He said ISRO has also decided to start assembling another engine so that the GSLV could fly at the earliest. Queried about the time-frame for the GSLV’s flight, he said: “It is not possible to give a time-frame for the GSLV’s flight now.”
