ISRO Chairman V. Narayanan confirmed on Sunday that the launch of the EOS-09 satellite via the PSLV-C61 mission was unsuccessful due to an issue encountered during the rocket’s third stage.
Speaking at a press conference, Narayanan explained that while the first and second stages of the launch functioned normally, the problem arose during the third stage, which uses a solid rocket motor designed to provide thrust after passing through the Earthโs atmosphere. โWe observed an anomaly during the third stage. The mission could not be completed. Our team is analyzing the performance, and weโll provide updates soon,โ he stated.
In a post on X, ISRO reiterated that while the initial phases of the mission progressed as planned, the third stage issue prevented the satellite from reaching its intended orbit.
This was ISROโs 101st launch attempt, aiming to place the Earth Observation Satellite EOS-09 into a Sun-Synchronous Polar Orbit. The mission included plans for post-launch deorbiting to reduce space debris and promote sustainable practices.
EOS-09, featuring C-band synthetic aperture radar technology, is capable of capturing high-resolution Earth images under all weather conditions, both day and night. It was designed to support various sectors with reliable remote sensing data and was equipped with deorbiting fuel to ensure safe disposal after its operational life.
Despite the setback, ISRO emphasized its commitment to responsible space operations and will continue efforts to analyze and resolve the issue.
