3rd stage pressure issue caused Earth observation mission failure: ISRO chief

for the local The Indian Space Research Organisation (ISRO) reported that its 101st mission, which involved launching an Earth observation satellite aboard the trusted PSLV rocket, could not be completed on Sunday due to a pressure issue in the third stage of the launch vehicle. While the Polar Satellite Launch Vehicle (PSLV) had a successful liftoff at the scheduled time of 5:59 am, the mission objectives were ultimately not achieved. According to spokesperson Narayanan, the mission targeted the PSLV-C61 EOS-09 launch from Sriharikota. He explained that the PSLV is a four-stage vehicle and that everything performed normally up to the second stage. However, a problem arose during the third stage, which is powered by a solid motor system.
