ISRO’s PSLV-C62 Mission Faces Setback After Third Stage Anomaly; Satellite Fails to Reach Orbit

India’s space agency ISRO suffered a setback on Monday when its PSLV-C62 mission, carrying the Anvesha (EOS-N1) satellite, failed to place the satellite into its intended orbit due to a technical anomaly during the third stage of the launch vehicle.

Although the rocket successfully lifted off and the high-performance solid third stage completed its burn and separated as planned, mission controllers soon began experiencing delays in receiving critical telemetry data. The fourth stage ignition was initiated, but subsequent updates were not received, leaving engineers uncertain about the satellite’s separation and orbital insertion.

The silence in the Mission Control Centre reflected growing concern as teams worked to assess the unfolding situation.

Later, ISRO Chairman Dr. V. Narayanan confirmed that a disturbance occurred during the third stage, causing a deviation in the rocket’s flight path. As a result, the satellite could not be correctly deployed into orbit.

“We observed an anomaly near the end of the third stage, following which the vehicle’s trajectory deviated. A detailed data analysis is currently underway, and we will share further information as soon as possible,” Dr. Narayanan said.

ISRO engineers are now examining all available flight data to determine the root cause of the failure and to prevent similar issues in future missions.
