ISRO's NVS-02 satellite suffers setback, thrusters fail to fire
New Delhi, Feb 2 (PTI): 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 elliptical orbit are being worked out," ISRO said.
After the GSLV rocket placed the satellite in the GTO, the solar panels on board the satellite were successfully deployed and power generation was nominal.
Communication with the ground station has been established, the space agency said.
The launch on board the GSLV was successful as all the stages performed flawlessly and the orbit was achieved with a high degree of precision.

Sujit Nair raises concerns over speculation of DMK-AIADMK understanding to block TVK
Chennai: Journalist and political commentator Sujit Nair has expressed concern over speculation that the Dravida Munnetra Kazhagam and the All India Anna Dravida Munnetra Kazhagam could explore a post-poll understanding to prevent Vijay-led Tamilaga Vettri Kazhagam from forming the government in Tamil Nadu.
In a social media post, Sujit Nair said the election verdict in Tamil Nadu reflected a clear public demand for political change and argued that the mandate should be respected irrespective of political preferences.
Referring to reports and political discussions surrounding a possible understanding between the DMK and AIADMK, he said he hoped such developments remained only speculative conversations and did not turn into reality.
Nair stated that if such an alliance were to take shape, it would raise serious questions about ideological politics in the country. He said TVK had emerged through a democratic electoral process and that the legitimacy to govern in a parliamentary democracy comes from the people’s verdict.
According to him, attempts to prevent an electoral winner from forming the government through unexpected political arrangements may be constitutionally valid, but many people could view them as politically opportunistic.
He further said that such a move could particularly affect the political image of the DMK, which has historically projected itself around ideology, social justice and opposition politics. Nair said that in ideological terms, the DMK appeared closer to TVK than to the AIADMK, and joining hands with its long-time political rival only to remain in power could weaken its broader political narrative.
He added that the same questions would apply to the AIADMK as well, as the party had spent decades positioning itself against the DMK and such an arrangement could create discomfort among its cadre and supporters.
Drawing a comparison with Maharashtra politics in 2019, Nair said he had expressed similar views when the Shiv Sena formed an alliance with the Indian National Congress and the Nationalist Congress Party after the Assembly elections.
He said post-poll alliances between long-standing political rivals often create a public perception that ideology and electoral mandates become secondary when political power equations come into play.
Nair also said such developments increase public cynicism towards politics and reinforce the belief among voters that ideology is often sidelined after elections.
He maintained that the Tamil Nadu verdict was emphatic and said respecting both the spirit and substance of the mandate was important for the credibility of democratic politics.
