PSLV-C61/EOS-09 mission not accomplished due to tech glitch : ISRO Chief
Sriharikota, May 18 (UNI) The PSLV-C61 mission carrying Earth Observation Satellite EOS-09 could not be accomplished on Sunday morning due to a technical glitch in ignition and separation of the third stage of the 4-stage rocket. ISRO Chairman V Narayanan told reporters that the mission could not be accomplished after it encountered some anomaly in its third stage. He said the rocket took off as scheduled at 0559 hrs and the ignition and separation of the first two stages were normal. However, during ignition and separation of the third stage (with solid propellants) a technical glitch was witnessed. "We are analysing it", he said, adding, the mission could not be accomplished. 'Today we targeted the 101st launch from Sriharikota, the PSLVC61 EOS-09 mission. The PSLV is a four-stage vehicle and up to the second stage, the performance was normal. The third stage motor started perfectly but during the functioning of the third stage we witnessed an anomaly and the mission could not be accomplished,' Mr. Narayanan said. Today 101st launch was attempted, PSLV-C61 performance was normal till 2nd stage. Due to an observation in 3rd stage, the mission could not be accomplished, he added. The EOS-09 satellite is seen as a game changer for surgical air strikes in the wake of prevailing tensions on the Pakistan and China borders and would provide high resolution border images using its onboard C-Band Synthetic Aperture Radar which will capture pictures on all weather conditions, day and night. After a 22-hr countdown, the workhorse and reliable launch vehicle of ISRO PSLV-C61 with strap-on motors lifted off majestically from the First Launch Pad lighting the dark skies at 0559 hrs, after initiating the launch sequence by the Mission Director 15 mts from take off, before th technical glitch in the third stage led to its failure.

What ISRO Chief Said After EOS-09 Satellite Launch Could Not Be Accomplished
Sriharikota: ISRO on Sunday could not accomplish the launch of an Earth observation satellite onboard a PSLV-C61 rocket after it encountered some anomaly in its third stage, the space agency's Chairman V Narayanan said. ISRO's trusted Polar Satellite Launch Vehicle (PSLV) is a 4-stage rocket and the first two stages were normal, he said. "Today we targeted the 101st launch from Sriharikota, the PSLVC61 EOS-09 mission. The PSLV is a four-stage vehicle and up to the second stage, the performance was normal. The third stage motor started perfectly but during the functioning of the third stage we are seeing an observation and the mission could not be accomplished," Mr Narayanan said. "After analysis we shall come back," he said in his brief address post the lift-off. EOS-09 is a repeat satellite similar to EOS-04 launched in 2022 that has been designed with the mission objective to ensure remote sensing data for the user community engaged in operational applications and to improve the frequency of observation. The mission's payload, a Synthetic Aperture Radar (SAR) which is inside the satellite, is capable of providing images for various earth observation applications under all-weather conditions day and night. This all-weather, round-the-clock, imaging is vital for applications, ranging from agriculture and forestry monitoring to disaster management, urban planning and national security. The rocket was earlier launched at a prefixed time of 5.59 am.

ISRO PSLV-C61 mission faces setback due to third stage anomaly
SRIHARIKOTA: In a setback for the Indian Space Research Organisation (ISRO), the launch of an Earth observation satellite onboard the PSLV-C61 rocket could not be completed successfully on Sunday after an issue was detected in the third stage of the vehicle. ISRO Chairman V Narayanan said the first two stages of the Polar Satellite Launch Vehicle (PSLV), which is a four-stage rocket, functioned normally before the problem occurred. "Today we targeted the 101st launch from Sriharikota, the PSLVC61 EOS-09 mission. The PSLV is a four-stage vehicle, and the performance was normal up to the second stage. The third stage motor started perfectly, but during the functioning of the third stage, we are seeing an observation, and the mission could not be accomplished," Narayanan said. "After analysis, we shall come back," he added in his brief address following the launch attempt.
