US EditionIndian space agency’s satellite mission fails due to technical issue in launch vehicle
- On May 17, 2025, India’s Space Research Organisation attempted to launch the EOS-09 satellite for Earth observation from the Sriharikota space center using the PSLV-C61 vehicle.
- The mission was unsuccessful due to a technical problem in the rocket's third stage caused by a drop in the motor case's chamber pressure.
- The launch vehicle performed normally until about 366 seconds after liftoff, when telemetry showed velocity slowing and deviation from planned flight.
- ISRO chairman V. Narayanan explained that a drop in pressure within the motor chamber during the rocket’s third stage led to the mission’s failure.
- This failure, the first PSLV failure since August 2017, resulted in loss of the nearly 1,700-kilogram EOS-09 satellite and halted data collection plans for operational applications.
