"Unforeseen Setback: Analysis of India's PSLV-C61 Mission Anomaly"
[!CDATA[India's recent Polar Satellite Launch Vehicle (PSLV-C61) mission faced an unexpected setback during the launch of the EOS-09 Earth observation satellite. The mission encountered an anomaly in the third-stage propulsion system, causing the rocket to deviate from its intended trajectory. As a result, the EOS-09 satellite, equipped with C-band Synthetic Aperture Radar (SAR) for all-weather imaging, failed to reach its planned orbit. This incident marks the third full failure in the PSLV program's history, with the last failure occurring in 2017. The issue with the third-stage propulsion system, which utilizes hydroxyl-terminated polybutadiene (HTPB) propellant, was detected 203 seconds into the flight. Isro Chief V Narayanan acknowledged the problem during the live stream following the launch. Engineers are currently examining telemetry data to pinpoint the cause of the anomaly, whether it be related to propellant flow, nozzle irregularities, or structural malfunctions. A failure analysis committee has been established to investigate the manufacturing and testing processes of the PS3 stage. The failure of the PSLV-C61 mission poses a setback to India's plans to enhance border surveillance and disaster response capabilities through SAR imaging. This mission was particularly significant as it marked ISRO's 101st launch, following a streak of 58 consecutive successful launches since 2017. Despite the termination of the rocket's fourth stage and the satellite, measures were taken to ensure the safe disposal of debris. In conclusion, the unexpected anomaly during the PSLV-C61 mission highlights the complexities and risks associated with space missions. ISRO's commitment to investigating the root cause of the failure demonstrates its dedication to ensuring the reliability and success of future launches.]]
