ISRO's PSLV-C61 EOS-09 launch aborted midway; ISRO Chief V. Narayanan explains why
Sriharikota: ISRO chairman V Narayanan addresses media after PSLV-C61 rocket carrying Earth Observation Satellite (EOS-09) lifted off from the first launch pad, in Sriharikota. After a precise liftoff, Chairman V Narayanan said that the mission could not be accomplished as planned. (PTI Photo/R Senthilkumar) India's latest satellite launch mission, EOS-09, failed to achieve its target after a pressure drop in the rocket's third stage. ISRO Chairman V Narayanan confirmed the anomaly and assured that investigations were underway. The launch, from Sriharikota's spaceport aboard PSLV-C61, was intended to place a powerful Earth observation satellite into orbit. This marks one of the few setbacks in ISRO's PSLV track record.

Remove Ads India's 101st space mission from Sriharikota suffered a major setback early Sunday when the Indian Space Research Organisation ISRO ) failed to complete the launch of its Earth observation satellite EOS-09. The mission lifted off as scheduled at 5:59 AM from the Satish Dhawan Space Centre but encountered an anomaly in the third stage of the Polar Satellite Launch Vehicle PSLV-C61 ).'Today we targeted the 101st launch from Sriharikota, the PSLV-C61 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,' ISRO Chairman V Narayanan said in a post-launch added, '...and the motor pressure—there was a fall in the chamber pressure of the motor case and the mission could not be accomplished. We are studying the entire performance, we shall come back at the earliest.'Though the PSLV-C61 launched without delay and performed reliably through its first two stages, the solid-fuel third stage failed to maintain the required pressure. This disruption halted the progress of the 1,696.24 kg EOS-09 satellite , which was designed for all-weather, day-and-night Earth rocket, towering at 44.5 metres and weighing 321 tonnes, was carrying the high-performance Synthetic Aperture Radar (SAR) payload, intended to support sectors like agriculture, disaster response, urban planning, forestry and national mission was also structured to be debris-free, with fuel reserved for de-orbiting the satellite after its operational life to prevent long-term space mission was the 63rd overall flight of the PSLV and the 27th using its heavier-lifting XL configuration. PSLV failures are rare. Since its first flight in 1993, ISRO has recorded just three setbacks, including Sunday's previous failures were PSLV-D1 in 1993 and PSLV-C39 in 2017, the latter due to a faulty heat shield that prevented satellite deployment. The current failure is expected to prompt an internal review as well as the formation of a Failure Analysis Committee The EOS-09 satellite, similar to the EOS-04 launched in 2022, was developed to enhance the frequency and reliability of remote sensing data. The SAR payload inside the satellite could have delivered high-resolution images even in cloudy or dark conditions—key for precision-based resource has confirmed that a detailed review will be undertaken to assess what went wrong. '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,' ISRO stated on its official X told CNN-News18 that a Failure Analysis Committee (FAC) will be set up to probe the issue. The FAC will include ISRO experts and members from the academic sector, and is likely to be headed by a former ISRO Chief or a senior retired scientist. The committee will comb through flight data, launch preparations, and all associated ISRO has not yet released its final technical report, Chairman Narayanan's assurance suggests the agency will soon regroup for another attempt. 'After analysis we shall come back,' he Sunday's setback, ISRO maintains a strong reputation for dependable launch missions. The EOS-09 failure may delay upcoming plans temporarily, but it also offers the opportunity to reinforce technical now, the space agency turns inward to evaluate its systems and regain momentum. India's ambitious space programme—marked by achievements like the Chandrayaan and Mars missions—remains undeterred. The mission may have failed, but the resolve remains intact.(With inputs from ANI, PTI)

PSLV-C61 mission could not be accomplished due to third stage pressure issue: ISRO
SRIHARIKOTA: In a setback for the Indian Space Research Organisation (ISRO), its 101st mission from here an earth observation satellite onboard the agency's trusted PSLV rocket, could not be accomplished on Sunday following a pressure issue in the third stage of the launch vehicle, the space agency said. A few minutes after the launch, its chairman V Narayanan came to arena to announce, 'During the functioning of the third stage, some observations were made. Mission not accomplished.' "Today we targeted the 101st launch from Sriharikota, the PSLV-C61 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," Narayanan said. This has come as a big blow for the Indian space sector which was launching the earth observatory satellite (EOS-09) as a part of its 101st mission. Not wanting to divulge further details, Narayanan told The New Indian Express, 'We are discussing the situation and we will get back.'

PSLV-C61 EOS-09 mission: When and where to watch Isro's 101st launch
India is set to launch its latest Earth observation satellite, EOS-09, aboard the Polar Satellite Launch Vehicle (PSLV-C61) from the Satish Dhawan Space Centre in mission marks the 101st launch from Sriharikota demonstrating Indian Space Research Organisation's (ISRO) ongoing commitment to bolstering the nation's space-based surveillance and disaster management also known as RISAT-1B, is equipped with a cutting-edge C-band synthetic aperture radar (SAR), enabling it to capture high-resolution images of the Earth's surface under all weather conditions, day or WHEN WILL ISRO LAUNCH PSLV-C61 EOS-09 MISSION? The Indian space agency will launch the powerful PSLV with EOS-09 from the Satish Dhawan Space Centre in Sriharikota on May 18, 2025, at 5:59 am advanced radar technology allows the satellite to see through clouds, rain, and darkness-overcoming the limitations of traditional optical imaging satellites. Weighing approximately 1,710 kilograms, EOS-09 will be placed in a sun-synchronous orbit, ensuring consistent lighting for its imaging TO SEE ISRO PSLV-C61 EOS-09 LAUNCH LIVE? India Today Science will be live to bring you all the real-time mission will broadcast the mission Live on its channel, which you can see below. WHAT WILL EOS-09 DO IN SPACE? The satellite features five imaging modes, ranging from ultra-high-resolution scans capable of detecting small objects to wide-area coverage for broader versatility makes EOS-09 a vital tool for a range of applications, including border surveillance, national security, agriculture, forestry, flood monitoring, and urban planning. Its ability to provide round-the-clock, reliable intelligence is especially significant given ongoing security concerns along India's borders with Pakistan and is a follow-on to the earlier RISAT-1 satellite and will complement India's growing constellation of Earth observation satellites, such as Resourcesat, Cartosat, and supplementing data from these satellites, EOS-09 will help deliver expanded real-time coverage across India, supporting smarter governance and faster, more effective disaster launch will be witnessed by more than two dozen members of Parliament, highlighting its national ISRO prepares for several key missions in the coming months, including the Gaganyaan crew escape test and the Indo-US NISAR satellite, the successful deployment of EOS-09 is set to further strengthen India's strategic and civilian capabilities in space-based monitoring and resource management.
