Earth observation mission: When ISRO's trusted workhorse PSLV suffered a rare setback

ISRO's most trusted and versatile launch vehicle, the PSLV, reportedly faced an unusual setback recently when it failed to place an earth observation satellite into its intended orbit. With a remarkable record of just three failures in 63 launches, the PSLV was anticipated to succeed once more. It seemed to be on track for the mission before the situation took a turn for the worse. According to the Bengaluru-headquartered space agency, the mission involving the earth observation satellite EOS-09 aboard the PSLV-C61 rocket could not be completed due to a pressure issue in the third stage of the launch vehicle. Known for its adaptability, the Polar Satellite Launch Vehicle has been utilised by ISRO to launch three types of payloads: Earth Observation, Geostationary, and Navigation.
