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!
Jai Hind!

Muscle Cells, Microalgae, Moong: NASA-ISRO-Shubhanshu Shukla's Science Lab In Orbit
NASA has revealed, as part of its collaboration with ISRO, Axiom Mission 4 delivers on a commitment highlighted by Prime Minister Narendra Modi and US President Donald Trump. The space agencies are participating in five joint science investigations and two in-orbit science, technology, engineering, and mathematics demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration. On his fortnight-long mission to the International Space Station next month, Group Captain Shubhanshu Shukla, India's 'gaganyatri', will conduct seven India-specific experiments in space, the Indian Space Research Organisation said today. These include studying 'water bears' - microscopic organisms - to understand how living things adapt to microgravity. According to ISRO, the experience will nurture a microgravity research ecosystem back home, leading to the induction of advanced experiments that make up India's space programme. The ISRO website, however, only lists sketchy details on these experiments, while NASA has given out full dossiers. India does not, at this time, have any deep experience of research in microgravity. In fact, this will be the first time an Indian will be working in a highly advanced space laboratory, one in which many complex experiments have been undertaken over the last 25 years. Science and Technology Minister Dr Jitendra Singh said Mr Shukla will focus on 'space technology, space bio-manufacturing, and bio-astronautics' during his mission. NASA, ISRO 's Science Lab In Orbit NASA and ISRO are collaborating to launch scientific investigations aboard Axiom Mission 4, the fourth private astronaut mission to the International Space Station. These studies include examining muscle regeneration, growth of sprouts and edible microalgae, survival of tiny aquatic organisms, and human interaction with electronic displays in microgravity. The mission will launch on Tuesday, June 10, aboard a SpaceX Dragon spacecraft on the company's Falcon 9 rocket from NASA's Kennedy Space Center in Florida. During long-duration spaceflights, astronauts lose muscle mass, and their muscle cells' regenerative ability declines. Researchers suspect this may happen because microgravity interferes with metabolism in mitochondria, tiny structures within cells that produce energy. The Myogenesis investigation uses muscle stem cell cultures to examine the muscle repair process and test chemicals known to support mitochondrial function. Results could lead to interventions that maintain muscle health during long-duration space missions, help people on Earth with age-related muscle loss and muscle-wasting diseases, and assist athletes and people recovering from surgery.

Sprouting Seeds The Sprouts-ISRO investigation looks at the germination and growth in microgravity of seeds from green gram or moong bean and fenugreek, nutritious plants commonly eaten on the Indian subcontinent. Bioactive compounds in fenugreek seeds or methi also have therapeutic properties, and the leaves contain essential vitamins and minerals. Learning more about how space affects the genetics, nutritional content, and other characteristics over multiple generations of plants could inform the development of ways for future missions to reliably produce plants as a food source. Microalgae Growth Culture bags for Space Microalgae. Image courtesy of Redwire. Space microalgae studies how microgravity affects microalgae growth and genetics. Highly digestible microalgae species packed with nutrients could be a food source on future space missions. These organisms also grow quickly, produce energy and oxygen, and consume carbon dioxide, traits that could be employed in life support and fuel systems on spacecraft and in certain scenarios on Earth. Tiny But Tough Tardigrades are tiny aquatic organisms that can tolerate extreme conditions on Earth. Voyager Tardigrade tests the survival of a strain of tardigrades in the harsh conditions of space, including cosmic radiation and ultra-low temperatures, which kill most life forms. Researchers plan to revive dormant tardigrades, count the number of eggs laid and hatched during the mission, and compare the gene expression patterns of populations in space and on the ground. Results could help identify what makes these organisms able to survive extreme conditions and support the development of technology to protect astronauts on future missions and those in harsh environments on Earth. Improving Electronic Interactions Research shows that humans interact with touchscreen devices differently in space. Voyager displays examine how spaceflight affects interactions with electronic displays, such as pointing tasks, gaze fixation, and rapid eye movements, along with how these interactions affect the user's feelings of stress or well-being. Results could support improved design of control devices for spacecraft and habitats on future space missions, as well as for aviation and other uses on Earth.
