The indigenous CE20 cryogenic engine that powers the upper stage of the LVM3 underwent a successful ignition trial using a multi-element igniter under vacuum circumstances, simulating engine ignition in the vacuum conditions of space. This test was conducted at the ISRO Propulsion Complex's High Altitude Test Facility in Mahendragiri, Tamil Nadu. In this test, a multi-element igniter was used to ignite the engine thrust chamber in vacuum under tank pressure circumstances that are anticipated to exist when the cryogenic engine is restarted in flight. During the test, the engine and the facility operated normally and according to expectations.
