The Indian Space Research Organisation’s (ISRO) 100th rocket mission was hampered on Sunday when its guidance satellite, which had been launched on Wednesday, had a technical fault.
In a report on the mission on its official website, ISRO stated that “orbit raising operations to position the satellite to the specified orbital slot could not be carried out because the valves for admitting the oxidiser to fire the thrusters for orbit raising did not open”.
The satellite, NVS-02, built by U R Rao Satellite Centre, was to be launched into a geostationary circular orbit over India. Because the satellite’s liquid engine isn’t working properly, efforts to get it to its intended orbit are either postponed or abandoned entirely.
“The satellite systems are functioning well, and the satellite is currently in elliptical orbit. Alternative mission methods for using the satellite for navigation in an elliptical orbit are being developed, according to ISRO.
ISRO successfully Sriharikota, Andhra Pradesh, marking its 100th mission
ISRO successfully launched its GSLV-F15 carrying the NVS-02 at 6:23 a.m. on Wednesday in Sriharikota, Andhra Pradesh, marking its 100th mission. The mission is also V Narayanan’s first as Chairman of the Space Agency, having recently taken office. It is also the ISRO’s first venture this year.
According to space specialists, the satellite will be unable to accomplish its assigned responsibilities due to its very elliptical orbit, which is over 170 kilometres to the nearest point to Earth and nearly 36,577 kilometres to the farthest point away.

The 2,250kg satellite, the second of its kind, was component of the Navigation with Indian Constellation (NavIC), a regional equivalent of the Global Positioning System (GPS).
NavIC, which India created during the 1999 Kargil war with Pakistan, has presented its own set of issues. During the battle, India was denied access to high-quality GPS data, and then-Prime Minister Atal Bihari Vajpayee later promised to create a specific version of GPS for the country’s strategic community.
However, many of the NavIC satellites failed to meet expectations. Since 2013, 11 satellites have been launched as part of NavIC, with six of them failing totally or partially for a variety of reasons, and the most recent one is also experiencing serious technical issues.
