Guruprasad explains EOS-09's 24/7 earth observation
Bengaluru, May 17 (UNI) The Indian Space Research Organisation (ISRO) is set to launch EOS-09, an advanced Earth observation satellite equipped with radar technology that can monitor the planet day and night, regardless of weather conditions, including through clouds.
This breakthrough capability will greatly enhance applications in agriculture, disaster management, urban planning, and other civilian sectors, officials said.
Dr B R Guruprasad, former ISRO scientist and current Director of the Jawaharlal Nehru Planetarium, told reporters that the radar sensor onboard EOS-09 enables it to function continuously, unlike traditional Earth observation satellites which rely on optical cameras and are limited by daylight and clear skies.
"This radar sends out radio waves and measures the reflected signals to build images of the Earth. Because it does not depend on sunlight, the satellite can observe the Earth both day and night, and in all weather conditions, including cloudy skies," Dr Guruprasad explained.
EOS-09, weighing approximately 1,700 kilograms, will be launched aboard the 63rd mission of the Polar Satellite Launch Vehicle (PSLV), specifically the PSLV-C61 variant, from the Sriharikota spaceport. The launcher used for this mission is the heaviest version of PSLV, known as the PSLV-XL.
According to Dr Guruprasad, ISRO has a history of launching radar-based Earth observation satellites, with the first such satellite launched as early as 2011. The upcoming EOS-09 mission continues this tradition and represents a significant upgrade in radar imaging technology.
"The satellite is primarily designed for civilian use, with applications including agriculture, forestry, disaster management, urban development, cartography, and weather monitoring," he said. 'The radar capability makes it particularly valuable in sectors that require reliable, timely information regardless of environmental conditions.'
ISRO's launch of EOS-09 is expected to strengthen India's capacity for resource management, disaster response, and scientific research, contributing to sustainable development and improved quality of life.

India pushes for global ocean pact at UN summit
New Delhi, June 10 (UNI) India on Tuesday made a powerful pitch for global ocean pact at the Third United Nations Ocean Conference (UNOC3), even as Union Minister of Science and Technology Dr. Jitendra Singh highlighted the country's leadership in deep-sea exploration, marine plastic reduction, and sustainable coastal development. Addressing the international gathering, Dr. Singh showcased India's ambitious Deep Ocean Mission, including the upcoming deployment of its first manned submersible, Samudrayaan, by 2026. He also emphasised India's national ban on single-use plastics, progress on the Swachh Sagar, Surakshit Sagar campaign, and the launch of the SAHAV digital ocean data portal, signaling India's rising influence in marine science and governance, according to a Union Science and Technology Ministry's statement. The Minister dwelled in details about the USD 80 billion port-led projects under the Sagarmala Programme as well as USD 2.5 Billion Fisheries Investment through the Pradhan Mantri Matsya Sampada Yojana (PMMSY). The Minister also said that as a green initiative to combat climate change threats, 6.6% of EEZ has been declared marine protected areas to support biodiversity goals, the statement added. 'Also, since 2022, over 50,000 tonnes of plastic waste removed from coastlines while 10,000 plus hectares of mangroves and nature-based shoreline solutions have been restored,' said the Minister. He also called on global leaders to ratify the BBNJ Agreement, finalize a legally binding Global Plastics Treaty, and adopt a bold Nice Ocean Action Plan to accelerate action for SDG-14: Life Below Water. Dr. Singh underscored the urgent need for science-driven, inclusive global partnerships. "The ocean is our shared heritage and responsibility. India stands ready to collaborate across sectors and borders for a sustainable ocean future," he declared. India also played a prominent role in global dialogues—co-leading Blue Talks with France and Costa Rica, and hosting high-level side sessions on marine spatial planning and climate-resilient coasts, he added.

Astronaut Shubhanshu Shukla on cusp of history to become second Indian in space
Indian astronaut Shubhanshu Shukla stands on the cusp of history as he prepares to set off on a space odyssey, marking India's return to space flight 41 years after his idol Rakesh Sharma orbited the earth for eight days as part of Soviet Union's Interkosmos programme. Lucknow-born Shukla, who goes by the call sign 'Shuks', is part of an ISRO-NASA supported commercial spaceflight by Axiom Space which is expected to lift off for a 14-day sojourn to the International Space Station from the Kennedy Space Centre in Florida on Wednesday evening. A Group Captain in the Indian Air Force, Shukla was selected to be part of India's astronaut corps in 2019 along with fellow officers Prasanth Balkrishnan Nair, Angad Pratap and Ajit Krishnan for the Gaganyaan mission which is likely to be launched in 2027.

He was commissioned into the Indian Air Force in 2006, and has over 2,000 hours of flying time on a wide range of aircraft including the Su-30 MKI, MiG-29, Jaguar, and Dornier-228. Live Events He holds an MTech in Aerospace Engineering from the Indian Institute of Science, Bengaluru. Shukla and the three other Gaganyaan astronaut designates underwent extensive training at Russia's Gagarin Cosmonaut Training Centre and ISRO 's Astronaut Training Facility in Bengaluru. Shukla's crewmates on the Axiom-4 mission, commander Peggy Whitson and mission specialists Tibor Kapu from Hungary and Slawosz Uznanski-Wisniewski from Poland, describe him as "operational-savvy", "focussed" and "wicked smart" when it comes to space technologies. "This is not just my journey; this is the journey of 1.4 billion Indians. Even if this story can change one life or inspire one young person, it will be a success," Shukla said in a press interaction ahead of the launch. Shukla's travel to space marks India's return to human spaceflight 41 years after Rakesh Sharma scripted history by undertaking a journey to space onboard Soviet Russia's Soyuz spacecraft in 1984. In Lucknow, Shukla's City Montessori School (CMS) has planned a "public watch party" to celebrate his spaceflight. Several hoardings have come up across the city congratulating 'Shuks' for his spaceflight. CMS has set up giant screens to relay the SpaceX launch live with NASA/Axiom commentary. "We are eagerly looking forward to the launch. Shuks is incredibly focused yet brimming with joy'," Suchi Mishra, Shukla's sister, said in Lucknow. During the 14-day stay at the ISS, the Ax-4 crew is expected to interact with Prime Minister Narendra Modi, school students, and space industry leaders, among others. Shukla is set to conduct exclusive food and nutrition-related experiments developed under a collaboration between the Indian Space Research Organisation (ISRO) and the Department of Biotechnology (DBT), with support from NASA . The experiments aim to pioneer space nutrition and self-sustaining life support systems vital for future long-duration space travel. ISRO has lined up a set of seven experiments for Shukla, who will also participate in five joint studies planned by NASA for its human research program. It has drawn up plans to focus on India-centric food for carrying out experiments on the ISS, including sprouting methi (fenugreek) and moong (green gram) in microgravity conditions. Shukla will also expose the seeds to the macrobiotic conditions and bring them back to earth where they will be cultivated into plants not just once but over generations. Shukla's experience on the Axiom Mission 4 would be very well utilised on the ISRO's Gaganyaan space flight mission which is planned for 2027. ISRO is spending Rs 550 crore on the Axiom-4 mission.
