Isro successfully carries out vacuum ignition trial of cryogenic engine

ISRO on Saturday said that it has successfully carried out the ignition trial of the indigenous CE20 cryogenic engine powering the upper stage of LVM3, with a Multi-element igniter under vacuum conditions, which simulates the engine ignition in the vacuum condition of space. This test was carried out on Friday in the High Altitude Test Facility at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu, ISRO said in a statement. This engine is crucial for the Gaganyaan mission, India's ambitious crewed space mission. During this test, the ignition of the engine Thrust Chamber was carried out with a multi-element igniter in a vacuum, under the tank pressure conditions that are expected to prevail at the time of restarting the cryogenic engine in flight. The performance of the engine and the facility during the test was normal and as expected. Restarting a cryogenic engine is inherently complex and as part of the studies related to the restart operation, ISRO is exploring the initiation of

Isro's NVS-02 satellite suffers setback after thrusters fail to fire

ISRO's attempts to place the NVS-02 satellite in the desired orbit suffered a setback after the thrusters on board the spacecraft failed to fire, the space agency said on Sunday. The NVS-02 satellite, which was crucial for India's own space-based navigation system, was launched on January 29 on board the GSLV-Mk 2 rocket which was ISRO's 100th launch from the spaceport at Shriharikota. "But the orbit raising operations towards positioning the satellite to the designated orbital slot could not be carried out as the valves for admitting the oxidizer to fire the thrusters for orbit raising did not open," the space agency said in an update to the GSLV-F15 mission on its website. The satellite is orbiting the Earth in an elliptical Geosynchronous Transfer Orbit (GTO) which is not suitable for the navigation system. "The satellite systems are healthy and the satellite is currently in elliptical orbit. Alternate mission strategies for utilising the satellite for navigation in an elliptica
