WATCH LIVE: PSLV-C61 all set to launch EOS-09 to space, give India imaging edge
India's latest Earth observation satellite, EOS-09 (also known as RISAT-1B), is all set to launch aboard the Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Centre in 1,710 kilograms, EOS-09 will be placed in a sun-synchronous polar orbit, ensuring it can capture images of the same area under consistent lighting conditions-vital for tracking changes over ISRO PSLV-C61 EOS-09 LAUNCH LIVE HERE EOS-09's standout feature is its advanced C-band synthetic aperture radar (SAR), which enables it to deliver high-resolution images of the Earth's surface regardless of weather or traditional optical satellites, EOS-09 can see through clouds, rain, and even in complete darkness, allowing for uninterrupted, round-the-clock surveillance and data collection. Its imaging resolution can reportedly reach up to one meter, making it possible to detect small objects and subtle changes in satellite is equipped with five distinct imaging modes, ranging from ultra-high-resolution 'spotlight' scans for detailed observation of small areas to wide-area coverage for broader surveillance.

Operation Sindoor sparks ISRO's bold leap: EOS-09 to guard India's Borders
Operation Sindoor (File) On Sunday, May 18, at 5:59 am, the Indian Space Research Organisation (ISRO) will launch its powerful PSLV-C61 rocket from Sriharikota, carrying the EOS-09 satellite, also known as RISAT-1B. This mission is not just another space launch—it's a game-changer for India's security and surveillance, especially after the recent Operation Sindoor, a daring counter-terror strike following the tragic killing of civilians in Pahalgam. With tensions high, EOS-09 is India's eye in the sky, ready to strengthen our borders and keep a sharp watch on every movement. The EOS-09 is a Radar Imaging Satellite (RISAT), part of ISRO's effort to build a strong network of Earth observation satellites. Unlike regular cameras, its Synthetic Aperture Radar (SAR) can take crystal-clear pictures of the Earth, even through thick clouds, heavy rain, or pitch-black nights. This makes it a superhero for border surveillance, disaster monitoring, and tracking enemy movements. Whether it's spotting intrusions along the India-Pakistan border or mapping floods and forests, EOS-09 is built to deliver frequent, high-quality images that our security forces and scientists need to act fast. This launch comes at a critical time. Operation Sindoor showed India's resolve to fight terrorism, but it also highlighted the need for constant vigilance. EOS-09 will provide real-time data to our forces, helping them track suspicious activities and respond swiftly. Its ability to capture images day or night, rain or shine, makes it a vital tool for keeping our borders safe and secure. The PSLV-C61, standing tall at 44.5 metres and weighing 321 tonnes, is a trusted workhorse. This is its 63rd flight and the 27th time it's flying in the powerful XL configuration, with extra-large boosters for added muscle. Just 17 minutes after liftoff, it will place the 1,696.2 kg EOS-09 into a Sun-synchronous polar orbit. This special orbit ensures the satellite passes over the same spot on Earth at nearly the same time every day, giving consistent images for monitoring changes in land, water, or weather patterns. What makes this mission even smarter is ISRO's focus on keeping space clean. EOS-09 carries extra fuel, not just for its five-year mission but to safely de-orbit when its job is done. This means the satellite will be brought down to burn up in the Earth's atmosphere within two years of its mission's end, leaving no space junk behind. Even the rocket's fourth stage will have its leftover fuel removed, following global safety rules to prevent explosions or debris that could harm other satellites. This launch also showcases ISRO's new Payload Integration Facility (PIF), used for only the second time after the Spadex mission in December. The PIF lets ISRO prepare the rocket separately and move it to the launch tower just before liftoff. This keeps the main launch pad free for other missions, helping ISRO launch more rockets faster and avoid delays. EOS-09 is a step forward from its predecessor, EOS-04, launched in 2022. It's designed to take pictures more often, giving scientists and agencies frequent updates about the Earth's surface. From agriculture and forest mapping to disaster management and border security, this satellite will play a big role in India's growth and safety. However, this mission follows a rare setback for ISRO. Just four months ago, the 100th launch failed to place the NVS-02 navigation satellite into its correct orbit. That was a reminder that space is tough, even for a space agency as reliable as ISRO. But with EOS-09, ISRO is bouncing back, showing the world that India's space programme is stronger than ever. As we watch the PSLV-C61 soar into the sky on Sunday, let's remember what's at stake. Operation Sindoor was a wake-up call, and EOS-09 is our answer—a powerful tool to protect our nation, monitor our lands, and keep our people safe. This is more than a satellite launch; it's a bold statement that India is watching, ready, and unstoppable. Let's cheer for ISRO as it lights up the skies and strengthens our nation's future!

PSLV-C61 launch countdown begins: Check all details on ISRO's EOS-09 Satellite Mission
What is EOS-09 (RISAT-1B)? Launch plan Mission life Live Events (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel The Indian Space Research Organisation (ISRO) has officially begun the 22-hour countdown for its upcoming PSLV-C61 mission, which is scheduled to launch at 5:59 am on May 18, 2025, from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The countdown began at 7:59 am on May 17, marking the final phase of preparation for what will be the 63rd flight of the Polar Satellite Launch Vehicle (PSLV) and ISRO 's 101st mission PSLV-C61 rocket will carry EOS-09 (also known as RISAT-1B), a next-generation Earth Observation Satellite weighing around 1,696 kilograms. The satellite is designed to provide high-resolution, all-weather imaging of the Earth's surface, which is crucial for a wide range of applications including agriculture, forestry, disaster management, urban planning, and national security. Once deployed, EOS-09 will join India's growing fleet of Earth observation satellites such as Resourcesat, Cartosat, and RISAT-2B, significantly enhancing the country's remote sensing PSLV-C61 will complete its mission in approximately 17 minutes, placing the satellite into a Sun Synchronous Polar Orbit (SSPO). After separation, Orbit Change Thrusters (OCTs) will be used to make fine adjustments to the satellite's orbit. The mission life of EOS-09 is expected to be five years, but ISRO has also planned a controlled de-orbiting process to ensure the satellite burns up safely in Earth's atmosphere after its operational life, reducing space debris and supporting sustainable space to ISRO, the EOS-09 satellite is a repeat of the EOS-04 mission launched in 2022 and acts as a follow-on to RISAT-1. Though the satellite was developed before the current year, its capabilities are being seen as a strategic asset in India's space-based Earth monitoring initiatives. The satellite will provide real-time, round-the-clock imaging, making it a vital tool for government agencies and researchers anticipation builds for the launch, ISRO has urged viewers to follow official channels for live coverage, images, and updates.
