<p>Bengaluru: The Indian Space Research Organisation has successfully carried out a demonstration of restarting its Vikas liquid engine at a test facility at Propulsion Complex in Mahendragiri, the space agency said on Saturday.</p>.<p>The space agency said the Vikas engine is the workhorse that powers the liquid stages of its launch vehicles.</p>.<p>This test on January 17 marks a milestone in the development of technologies for recovery of stages, leading to reusability in future launch vehicles, according to an ISRO statement.</p>.<p>A series of tests are being carried out to validate the restarting of the engine under different conditions.</p>.<p>"In this test, the engine was fired for 60 seconds after which it was shut-off for a period of 120 seconds followed by restart and firing for seven seconds duration. All engine parameters during the test were normal and as expected," the ISRO said.</p>.<p>Previously, a shorter duration restart was carried out successfully in December 2024 with a shut-off time of 42 seconds and firing duration of seven seconds each.</p>.ISRO releases video of historic space-docking test of satellites under SpaDex mission.<p>Further tests are planned in coming days to optimise the performance of the engine under restart conditions, the statement read.</p>.<p>Also, ISRO Chairperson V Narayanan flagged off the core liquid stage (L110) of ISRO's LVM3 launch vehicle on Friday to the launch complex at Sriharikota.</p>.<p>The stage was designed and developed by Liquid Propulsion Systems Centre (LPSC) during the development of the LVM3 launch vehicle and is powered by twin Vikas engines with a propellant loading of 110 tonnes, the ISRO said.</p>.<p>"This stage is the tenth L110 liquid stage integrated at ISRO Propulsion Complex, Mahendragiri and is earmarked for the LVM3 mission under a commercial agreement between NewSpace India Limited (NSIL) and AST SpaceMobile & Science, LLC to launch their BlueBird Block 2 satellite," the agency said in a statement.</p>
