PSLV-C62 Suffers Third-Stage Failure; Most Payloads Lost as Spanish Capsule Sends Data

A formal investigation is underway, with outside reports describing a pause in PSLV operations pending review.

Overview

  • ISRO confirmed an anomaly near the end of the PSLV-C62 third stage that caused a flight-path deviation and prevented orbital insertion.
  • Fifteen of sixteen satellites are reported lost, including DRDO’s EOS‑N1 (Anvesha), AayulSAT, CGUSAT, and a UKThailand Earth‑observation payload, though some reports say all sixteen were lost.
  • Orbital Paradigm’s 25‑kg KID re‑entry capsule separated, powered on, and transmitted roughly 190 seconds of telemetry, recording about 28g with internal temperatures around 15–30°C.
  • The company is reconstructing KID’s off‑nominal trajectory and preparing a detailed technical report after the capsule endured a much steeper descent than planned.
  • This is the second consecutive PSLV third‑stage problem since May 2025, prompting concerns over reliability and transparency and, according to multiple outlets, a review that could delay upcoming commercial launches.
