India’s PSLV-C61 Rocket Fails to Deploy EOS-09 Satellite Due to Third-Stage Technical Fault
A Failure Analysis Committee will review the flight data and systems to ensure corrective measures are implemented for future launches.

India’s latest satellite launch mission faced a setback when the PSLV-C61 rocket failed to place the EOS-09 Earth Observation Satellite into orbit.
The launch, conducted on May 18, 2025, from the Satish Dhawan Space Centre in Sriharikota, was progressing normally until the third stage of the rocket experienced a sudden drop in chamber pressure.
This technical anomaly prevented the rocket from achieving the intended orbit, resulting in mission failure.
The EOS-09 satellite, equipped with Synthetic Aperture Radar technology, was designed to provide all-weather, day-and-night Earth observation capabilities to support applications such as agriculture, forestry, and disaster management.
The failure marks a rare but significant disruption in the otherwise reliable history of the PSLV program.
ISRO Chairman V. Narayanan confirmed the incident and stated that a comprehensive investigation is underway to identify the root cause of the pressure drop in the third stage motor.
