ISRO successfully carries out ground static test of PSLV third stage
The Indian Space Research Organisation (ISRO) successfully conducted a ground static test of the PSLV third stage engine. This follows design and quality control improvements implemented after anomalies were detected in previous missions.
Why it matters
Successful testing is critical for restoring the reliability of India's workhorse launch vehicle and maintaining the country's space program schedule.
Bengaluru The Indian Space Research Organisation (ISRO) which is looking to get its workhorse launcher, the Polar Satellite Launch Vehicle (PSLV), back on track has successfully carried out the ground static test of the PSLV third stage (PS3) at the Static Test Facility in Satish Dhawan Space Centre, Sriharikota on Thursday (November 12, 2026). “Subsequent to the anomalies observed in the third stage of PSLV during the PSLV-C61/EOS-09 & PSLV-C62 / EOS-N1 missions, the configuration of the PS3 stage was revisited comprehensively with respect to the design margins, raw material acceptance criteria, assembly procedures, and the quality checks that were followed so far,” ISRO said.
