Faltering Trajectory

India’s Polar Satellite Launch Vehicle has long been treated as a model of quiet reliability. However, that reputation is now under strain after the PSLV-C62, carrying 16 satellites, experienced a deviation during its third stage of flight shortly after lifting off from Sriharikota. ISRO confirmed that the rocket did not proceed along its expected trajectory, though it has stopped short of declaring the mission a failure.
In most launch vehicles, the third stage is where a mission is effectively decided. A problem at this point rarely allows a satellite to reach its intended orbit. That was the case last year when the only PSLV flight of the year failed at precisely this phase. The repetition of the same problem a year later is therefore difficult to dismiss as coincidence. PSLV-C62 was meant to mark the vehicle’s return to service after that setback. Instead, it has reopened questions that ISRO never fully answered.
For decades the PSLV has been the backbone of India’s space programme. It has lofted lunar probes, interplanetary missions and hundreds of commercial satellites, giving India a reputation for affordable and dependable access to orbit. With only four failures in its first 63 launches, the vehicle came to symbolise ISRO’s understated competence. The fifth failure, if confirmed, would not in itself be catastrophic. But two consecutive breakdowns in the same stage of flight suggest something more troubling than statistical bad luck.
After the 2025 failure, ISRO followed standard procedure by appointing a failure-analysis committee. What it did not do was publish the committee’s findings. The engineering community, satellite customers and even parts of India’s own space ecosystem were left in the dark about what went wrong and how it was fixed. When a launch vehicle flies again without such clarity, it asks its users to trust that the problem has been solved. PSLV-C62 now casts doubt on that assumption.
The implications stretch far beyond ISRO’s own laboratories. This flight carried satellites from Brazil, Nepal and Britain, all of whom entrusted Indian hardware with their orbital ambitions. It also carried seven satellites belonging to Dhruva Space, a Hyderabad-based start-up that represents the new private face of India’s space sector.
The Indian government has made commercial space a strategic priority. It has opened satellite manufacturing, data services and even rocket production to private players, hoping to replicate in orbit the start-up energy that transformed its software industry. The PSLV sits at the centre of this plan. It is the rocket that most Indian firms expect to use, and the one foreign customers already recognise.
Repeated third-stage anomalies undermine that confidence. ISRO has earned enormous goodwill through decades of frugal innovation. It remains a technically formidable organisation. But as India seeks to become a commercial space power, its national agency must behave like one.
If India wants the world to keep betting on the PSLV, ISRO will need to offer something more than reassurance. It will need to offer answers.
