The Hindu
ISRO's PSLV-C61 rocket failed to launch Earth observation satellite EOS-09 due to anomaly in third stage.
The Indian Space Research Organisation (ISRO) could not accomplish its 101st launch, the PSLV-C61/EOS-09 mission on Sunday (May 18, 2025).
Minutes after PSLV-C61 with the EOS-09 Earth observation satellite lifted off from the Satish Dhawan Space Centre in Sriharikota at 5:59 a.m., the space agency said that the mission could not be accomplished due to an observation in the third stage of the launch vehicle.
At around 17:65 minutes after lift off the ISRO’s workhorse PSLV was to place the satellite into the instented Sun Synchronous Polar Orbit (SSPO). However the mission could not be accomplished.
“Today from Sriharikota the PSLV-C61/EOS-09 mission was targeted. the PSLV is a four stage vehicle and the second stage performance was quite normal. The third stage motor started perfectly but during the functioning of the third stage we are seeing an observation and the mission could not be accomplished. After analysis we shall come back,” ISRO Chairman V. Narayanan said.
“Today 101st launch was attempted, PSLV-C61 performance was normal till 2nd stage. Due to an observation in 3rd stage, the mission could not be accomplished,” ISRO posted on X.
The EOS-09 is a repeat satellite of EOS-04, designed with the mission objective to ensure remote sensing data for the user community engaged in operational applications and to improve the frequency of observation.
The space agency said that the spacecraft is configured using ISRO’s RISAT-1 heritage bus, with most of the functional requirements of the Synthetic Aperture Radar (SAR) payload and the bus platform systems derived from the earlier ISRO missions.
