India's space agency suffers setback as it fails to launch satellite
India's space agency says it has failed to place the EOS-9 surveillance satellite into the intended orbit after its launch vehicle PSLV-C61 encountered a technical issue in a rare setback for the agency, known for its low-cost projects. The EOS-09 Earth observation satellite took off on board the PSLV-C61 launch vehicle from the Satish Dhawan Space Centre in Sriharikota, located in the southern Indian state of Andhra Pradesh, on Sunday morning. 'During the third stage … there was a fall in the chamber pressure of the motor case, and the mission could not be accomplished,' said V Narayanan, chief of the Indian Space Research Organisation (ISRO). 'We are studying the entire performance, we shall come back at the earliest,' he said in a statement to local media. The world's most populous nation has a comparatively low-budget aerospace programme that is rapidly closing in on the milestones set by global space powers. Active in space research since the 1960s, India has launched satellites for itself and other countries, and successfully put one in orbit around Mars in 2014. In August 2023, India became just the fourth nation to land an unmanned craft on the moon after Russia, the United States and China. Since then, ISRO's ambitions have continued to grow. Its first attempt to land on the moon failed in 2019. So far, ISRO has recorded three setbacks in PSLV missions, including Sunday's. The first failure was in 1993. On Sunday, Narayanan said ISRO would study the performance and provide details on what went wrong at a later stage. According to local media reports, a Failure Analysis Committee will also be set up to investigate the space agency's latest setback.

Indian space agency's satellite mission fails due to technical issue
The Indian space agency's mission to launch into orbit a new Earth observation satellite failed after the launch vehicle encountered a technical issue during the third stage of flight, officials said. The EOS-09 Earth observation satellite took off on board the PSLV-C61 launch vehicle from the Sriharikota space centre in southern India on Sunday morning.

Active in space research since the 1960s, India has launched satellites for itself and other countries, and successfully put one in orbit around Mars in 2014. After a failed attempt to land on the moon in 2019, India became the first country to land a spacecraft near the moon's south pole in 2023 in a historic voyage to uncharted territory that scientists believe could hold reserves of frozen water. The mission was dubbed a technological triumph for the world's most populous nation. Advertisement

Why did EOS-09 satellite mission fail? ISRO reveals initial observation
After taking off at the scheduled time of 5.59 am on Sunday, the 101st launch of the Indian Space Research Organisation (ISRO) failed mid-flight during its third stage, just minutes after the launch. ISRO's otherwise reliable PSLV C61 rocket launched from Satish Dhawan Space Centre in Sriharikota with EOS 09, an earth observation satellite, onboard. The mission was to carry the Earth observation satellite into a Sun Synchronous Polar Orbit (SSPO). However, the launch suffered a technical glitch during the third stage of PSLV's flight and failed.

Due to an observation in the 3rd stage, the mission could not be accomplished,' said the space agency. According to ISRO's Chairman V Narayanan, the Polar Satellite Launch Vehicle is a 4-stage rocket, and the first two stages were normal. However, during the third stage, there was a 'fall in the chamber pressure of the motor case' which caused the mission failure. Also read: EOS-09 mission: What ISRO said on the failed satellite launch "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," Narayanan said. "...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," he added, according to a PTI report. EOS-09 is a repeat satellite of EOS-04, 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, according to ISRO. The mission was ISRO's 101 launch. Had the mission been successful, the Orbit Change Thrusters (OCT) would have been used to reduce the altitude of the PS4 stage, followed by passivation to limit its orbital life after the deployment of EOS-09. The mission carried a Synthetic Aperture Radar (SAR) payload capable of providing images for various earth observation applications under all-weather conditions.

ISRO Chairman V. Narayanan Announces Upcoming Weather Surveillance Satellite EOS-09
New Delhi: The Indian Space Research Organisation (ISRO) is set to launch its 101st satellite, EOS-09, aboard the Polar Satellite Launch Vehicle (PSLV-C61) on May 18, 2025. According to ISRO Chairman V. Narayanan" The launch is scheduled for 5:59 am from the Satish Dhawan Space Centre in Sriharikota". The PSLV-C61 rocket was transported to the Mobile Service Tower at the Satish Dhawan Space Centre in Sriharikota for final integration and checks before its scheduled launch on May 18. Former ISRO scientist Purohit also mentioned that EOS-09 would serve as a follow-on to the earlier RISAT-1 mission. This launch is strategically timed," said former ISRO scientist Manish Purohit. "It strengthens monitoring at borders and coasts, particularly with respect to sensitive areas. The satellite can detect ingress or suspicious movement deemed vital in anti-terror operations, especially after the recent Pahalgam terror attack and Operation Sindoor," added Purohit. Earlier ISRO Chairman V. Narayanan stressed the critical role of satellite technology in national security and governance, stating, "With the PSLV-C61/EOS-09 mission, ISRO continues to demonstrate its commitment to both technological excellence and the national interest." IN-SPACe Chairman Pawan Kumar Goenka echoed this sentiment, emphasizing the need for constant enhancement of capabilities. ISRO is gearing up to launch the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite on the GSLV-F16 mission. NISAR will utilize dual-band radar technology from both NASA and ISRO to monitor Earth's surface changes, ecosystems, and natural disasters, providing valuable insights into our planet's dynamics. The EOS-09 satellite is a cutting-edge Earth observation satellite designed to bolster India's space-based surveillance capabilities. Fitted with advanced C-band synthetic aperture radar technology, it can capture high-resolution images of the Earth's surface regardless of weather conditions or time of day. This capability enables effective monitoring and management across various sectors.
