ISRO Probes PSLV-C62 Third-Stage Anomaly After Flight Path Deviation

The setback follows a similar third-stage issue in May 2025 that led to extensive checks on the workhorse launcher.

Overview

  • PSLV-C62 lifted off from Sriharikota at about 10:18 a.m. IST, using the PSLV-DL variant on ISRO’s first mission of 2026.
  • ISRO reported increased roll-rate disturbance near the end of the solid-fuel third stage and a subsequent deviation from the planned trajectory, triggering a detailed telemetry analysis.
  • The mission was intended to place the EOS-N1 (Anvesha) Earth observation satellite and 15 co-passenger payloads into a sun-synchronous orbit and to demonstrate the KID re-entry capsule, with successful deployment not confirmed by ISRO.
  • Multiple outlets report the payloads did not reach the target orbit and that all 16 satellites were lost, but ISRO has not issued a final technical determination.
  • The incident is the second consecutive third-stage problem for PSLV after the May 2025 C61 anomaly and comes on a launcher with a long record of high reliability and significant commercial participation via NSIL, including seven satellites from Dhruva Space.
