ISRO stated that the disengagement of at least one contact -- in both the main and redundant paths -- of a connector led to the failure of NVS-02.
The move follows a quiet visit by National Security Advisor Ajit Kumar Doval to the Vikram Sarabhai Space Centre in Thiruvananthapuram.
Based on the broadcast visuals, a rocket expert said the failure appeared similar to the anomaly seen during the PSLV-C61 mission.
These upcoming launches carry added significance in light of setbacks suffered in recent years.
'A solid motor, once ignited, burns until the propellant is exhausted. It cannot simply stop mid-burn,' said a retired senior ISRO official. 'That is what makes this failure puzzling.' Venkatachari Jagannathan reports on the latest PSLV failure.
ISRO Chairman V Narayanan announces ambitious space program goals, including landing Indians on the Moon by 2040 and launching the 'Gaganyaan' mission in 2027. The agency is also working on a national space station and uncrewed missions.
The need for NavIC was cemented after India was denied access to crucial navigation data from global providers during the 1999 Kargil War.
ISRO chairman announces plans for nine major launches by the end of the fiscal year, including the Blue Bird Block2 communication satellite for the US in collaboration with NASA.
The Indian Space Research Organisation will open 2025 scoring a century orbiting the country's navigation satellite 2,250 kg NVS-02 with its rocket Geosynchronous Satellite Launch Vehicle (GSLV)-F15.
ISRO's vendor policy and quality control processes are under scanner.
The Indian Space Research Organisation successfully launched its 100th mission on Wednesday, with a GSLV rocket carrying navigation satellite NVS-02.
'There's too much coincidence in back-to-back failures of missions critical to national security.'
At 6.23 am on 29.1.2025, the 50.9 metre tall and weighing 420.7 ton Geosynchronous Satellite Launch Vehicle-F15 (GSLV-F15) is slated to blast off from the second launch pad carrying the 2,250 kg NVS-02 navigation satellite.
'The work is already on with various data being studied.'
'The satellite's condition is healthy.'
ISRO is part of an exclusive league which has forayed into the Moon and Sun.
A PSLV rocket carrying Earth observation satellite EOS-09 failed to launch from the Sriharikota spaceport early on Sunday.
The Indian Space Research Organisation (ISRO) on Monday successfully launched a second generation navigation satellite, using a GSLV rocket with a cryogenic upper stage to do the job.
NavIC consists of a constellation of seven satellites and a network of ground stations and is touted to be more accurate than GPS.
The space agency has redefined the mission in such a way that it will achieve success in the very first attempt.
'When a Project Director is appointed, the whole organization -- including the Chairman ISRO -- works for his success. It is a lesson that has been of abiding value all through the other projects I have worked on,' recalls the late President, one of the earliest pioneers at ISRO.
With the Centre issuing guidelines for their resumption under Unlock 4, the rapid transit networks started operations in a graded manner in Delhi-NCR, Lucknow, Kochi, Chennai, Hyderabad, Bengaluru and Ahmedabad, but were still closed in Mumbai, Nagpur, Kolkata and Jaipur.
