At 10.18 am on Tuesday, the Polar Satellite Launch Vehicle (PSLV)-C62 lifted off from the Satish Dhawan Space Centre in Sriharikota, carrying 16 satellites into space. The launch marked the first PSLV mission of the year and was being closely watched as a comeback attempt following a failure in 2025.
Roughly 30 minutes after liftoff, the Indian Space Research Organisation (ISRO) stated that the mission had “encountered an anomaly” during its third stage. The space agency has initiated a detailed analysis but has not yet officially declared the mission a failure.
Third stage issue raises concerns again
The PSLV is a four-stage launch vehicle, with the first two stages reportedly performing as expected during Tuesday’s mission. The problem surfaced during the third stage, where deviation was observed.
ISRO chairman Dr V Narayanan said that a detailed assessment is underway. Historically, issues during the third stage of a rocket have often resulted in mission failure, although ISRO has so far avoided using that term for this launch.
The setback is significant as this was intended to be a recovery mission. The PSLV’s only launch in 2025 had also failed due to a third-stage issue. An analysis committee was formed after that failure, but its findings were not made public.
Mission payload and satellite loss
The mission aimed to place a surveillance satellite into orbit. The earth observation satellite, named Anvesha, was developed by the Defence Research and Development Organisation. Alongside it, the PSLV carried 15 additional satellites from multiple countries, including Brazil, Nepal and the UK.
With the anomaly occurring mid-mission, these satellites are now believed to be lost.
Track record remains strong despite setback
The PSLV has completed 64 missions so far, with four failures recorded prior to this launch. If the current mission is eventually declared unsuccessful, it would mark the fifth failure, keeping the overall success rate relatively high.
However, the timing of the anomaly is a concern, given the growing reliance on PSLV for commercial and strategic launches.
Impact on space industry and future launches
The development is particularly worrying for private players in India’s expanding space ecosystem. Several start-ups had payloads on this mission, including Hyderabad-based Dhruva Space, which had placed seven satellites onboard.
The outcome also casts uncertainty over the planned industry-led PSLV launch scheduled for the first half of 2026. That mission is being developed with participation from Hindustan Aeronautics Limited and Larsen and Toubro.
ISRO is expected to conduct a thorough investigation into the third-stage issue before finalising the status of the mission and outlining corrective measures.
