PSLV Rocket Faces Anomaly During Stage 3 of Launch, ISRO Analysing Data
India’s space agency confirmed that the PSLV-C62 mission experienced an unexpected anomaly during the end of its third stage, prompting a detailed analysis of flight data as officials assess the impact on satellite deployment.
India’s Polar Satellite Launch Vehicle (PSLV-C62) — carrying the EOS-N1 Earth observation satellite along with 15 co-passenger satellites — encountered an anomaly during the third stage (PS3) of its launch today from the Satish Dhawan Space Centre, Sriharikota.
According to the Indian Space Research Organisation (ISRO), the vehicle lifted off normally, but a deviation in the flight path was observed as the third stage was nearing completion, leading to concerns about whether the mission achieved the necessary velocity and trajectory for successful satellite deployment.
Telemetry indicates a disturbance in roll rates and significant path deviation, which occurred just before the rocket could reach the planned orbit insertion parameters. ISRO has stated that it has initiated a detailed analysis of flight data to understand the root cause of the anomaly and assess what happened with the satellites onboard.
The mission was particularly significant as it marked India’s first PSLV launch of 2026 and aimed to boost the country’s Earth observation capabilities with the strategic EOS-N1 payload.
ISRO’s official reports confirm the issue occurred at the end of the PS3 stage, and experts are now combing through telemetry and vehicle data to determine whether corrective action is possible or if the payloads were lost. Further updates are expected as analysis progresses.
