Indian Space Research Organisation successfully conducted the second static testing of its liquid core stage (L110) of Geo-synchronous Satellite Launch Vehicle (GSLV Mk -III) for 200 seconds at its Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri on September 8, 2010 at 15:50 hrs.

L110 is one of the heaviest earth storable liquid stages ever developed by ISRO. L110 stage had two high pressure Vikas engines in a clustered configuration. Nearly 500 health parameters were monitored during the test and the initial data acquired indicates its normal performance.  successful test of L110 for its full flight duration of 200 seconds, is a major mile stone in the earth storable liquid rocket programme of ISRO and a significant step forward in the development of GSLV-Mk III launch vehicle.

It may be recalled that GSLV-Mk III, which is currently under advanced stage of development uses two solid strap on boosters (S200), L-110 liquid stage and a cryogenic upper stage C-25.
