ISRO to Test Heavy-Lift Stage on Wednesday

ISRO to conduct key test for GSLV Mk III rocket next week

After a failed test six months ago, Indian Space Research Organisation (ISRO) will be making a fresh attempt next week to conduct long-duration static test of a crucial liquid core stage for a new generation heavy rocket which is being developed.

“The static test of crucial liquid core stage (L110) of GSLV Mk III launch vehicle (rocket) for 200 seconds is slated for 3 pm on September eight,” a senior ISRO official told PTI here.

A top ISRO team, including Director of ISRO’s Liquid Propulsion Systems Centre (LPSC) S Ramakrishnan and Director of Vikram Sarabhai Space Centre (VSSC) P S Veeraraghavan, held a review meeting in Mahendragiri in Tamil Nadu on Wednesday and gave the go-ahead for the test…

ISRO conducted the test for 150 seconds at LPSC test facility on March five. While the test was originally targeted for 200 seconds, it was stopped at 150 seconds since a deviation in one of the parameters – minor leakage in the command system – was observed.

A small leak in the command line was detected by computer, which automatically aborted the test. About 500 important parameters were monitored during the static test.
