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

Countdown begins for Isro's 100th mission to launch navigation satellite

The 27-hour countdown for ISRO's historic 100th mission from this spaceport, launch of a Navigation satellite onboard a GSLV rocket commenced on Tuesday, sources in the space agency said. Also, this would be the first mission for ISRO Chairman V Narayanan, who assumed office on January 13. The Geosynchronous Satellite Launch Vehicle (GSLV) with indigenous Cryogenic upper stage in its 17th flight, carrying the navigation satellite NVS-02 is scheduled for lift-off at 6.23 am on January 29 from the second launch pad here. The navigation satellite is the second in the series of the Navigation with Indian Constellation (NavIC) aimed to provide accurate position, velocity and timing to users in the Indian sub-continent as well as to regions about 1,500 km beyond the Indian land mass. "The 27.30 hour countdown commenced at 02.53 am on Tuesday," multiple sources told PTI. The 50.9 metre tall GSLV-F15 follows the GSLV-F12 mission which successfully carried navigation satellite NVS-01, the .

GSLV-F15 integration with satellite NVS-02 complete, ready for launch: Isro

ISRO on Sunday said integration of its rocket GSLV-F15 with satellite NVS-02 is complete. The GSLV-F15 rocket with Indigenous cryogenic stage is ready to be launched on January 29, with the satellite NVS-02 on board, the space agency said. This will be the 100th mission from Satish Dhawan Space Centre in Sriharikota, "GSLV-F15 integration complete! Take a sneak peek at the incredible teamwork behind this mission: Countdown: Less than 3 days to launch! Join us as we unlock new frontiers," the agency said in a post on social media 'X'. GSLV-F15 will place the NVS-02 satellite into a Geosynchronous Transfer Orbit and the launch will take place from the Second Launch Pad of Satish Dhawan Space Centre, said ISRO. NVS-01, the first of the second-generation satellites, was launched on board GSLV-F12 on May 29, 2023.

SpaDeX successful, results will pave way for future missions: Isro chief

ISRO chairman V Narayanan on Saturday said the space-docking experiment (SpaDeX) of satellites was successful and the results will be useful for multiple purposes, including future missions like Chandrayaan 4, Gaganyaan and India's space station. Narayanan, who arrived in Kerala after the successful space-docking test, told reporters at the airport here that it was a team effort by the ISRO and the results of the test were being reviewed. "Right now the situation is that all the things are successfully docked and it is in space safely. Now we are studying all the results. My team is reviewing the results and we will take the proper decision at the proper time," he said. The scientist further said that the docking experiment would be useful for multiple purposes. Giving details, he said that it will be useful for the Chandrayaan 4 mission as two rockets will be used to carry to space the over 9,000 kg module that will subsequently land on the moon for sample collection. He said tha
