The distinctive Earth remark satellite NASA-ISRO Synthetic Aperture Radar (NISAR) will likely be launched by way of the GSLV-S16 on July 30, mentioned ISRO chairman V Narayanan.
Weighing 2,392 kg, NISAR is a singular Earth remark satellite and the primary to observe the Earth with a dual-frequency Synthetic Aperture Radar (NASA’s L-band and ISRO’s S-band) each utilizing NASA’s 12m unfurlable mesh reflector antenna, built-in to ISRO’s modified 13k satellite bus.
It will observe earth with a swath of 242 km and excessive spatial decision, utilizing SweepSAR know-how for the primary time, in accordance to the house company.
It will likely be launched from the Satish Dhawan Space Centre, Sriharikota.
“The Earth observation satellite jointly developed by ISRO and NASA will be sent into space on July 30 by the GSLV-F16 rocket made in India,” Indian Space Research Organisation chairman V Narayanan mentioned.
It will likely be launched at a distance of 740 km. It can take footage of the earth 24 hours a day in all climate circumstances and the satellite can detect landslides, support in catastrophe administration and monitor local weather change, he mentioned whereas talking to reporters on the airport in Chennai on Sunday (July 27, 2025) evening.
“The satellite will benefit India, the U.S. and the entire world… it is also crucial for monitoring earth’s natural resources,” he added.
On Gaganyaan, India’s human spaceflight Mission, Narayanan mentioned a humanoid, known as Vyommitra, will likely be despatched into house in December this yr. Once it proved to achieve success, two different uncrewed missions could be launched subsequent yr.
Following the success, the Gaganyaan Mission will likely be launched in March 2027 as Prime Minister Narendra Modi has mentioned.
‘NISAR’ launch will upscale ISRO’s worldwide collaborations, says Jitendra Singh
Union Minister for Science and Technology Dr Jitendra Singh disclosed that the much-anticipated launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite mission is scheduled for July 30, 2025, at 17:40 hrs from the Satish Dhawan Space Centre, Sriharikota.
As the primary joint Earth remark mission between the Indian Space Research Organisation (ISRO) and the United States’ National Aeronautics and Space Administration (NASA), the occasion marks a defining second within the journey of Indo-US house cooperation and in addition in ISRO’s general worldwide collaborations, he mentioned. The mission will likely be launched aboard India’s GSLV-F16 rocket.
Mr. Singh, who has been monitoring the mission intently, mentioned the launch displays the maturing of strategic scientific partnerships and India’s emergence as a reputable world participant in superior Earth remark methods. While expressing his want to be bodily current in Sriharikota to witness the historic occasion, the Minister acknowledged that the continued Parliament session could maintain him again in Delhi.
“This mission is not just about a satellite launch–it is a moment that symbolises what two democracies committed to science and global welfare can achieve together. NISAR will not only serve India and the United States but will also provide critical data for countries around the world, especially in areas like disaster management, agriculture, and climate monitoring,” mentioned Dr Singh.
Mr. Singh additional famous that this mission lives up to Prime Minister Narendra Modi’s imaginative and prescient of India turning into a ‘Vishwa Bandhu’–a world associate that contributes to the collective good of humanity.
A key characteristic of the mission is that each one information generated by NISAR will likely be made freely accessible inside one to two days of remark and in close to real-time in case of emergencies. This democratisation of knowledge is anticipated to help world scientific analysis and decision-making, particularly for creating international locations that will not have entry to comparable capabilities.
Notably, the NISAR mission is the primary time a GSLV rocket is getting used to place a satellite in sun-synchronous polar orbit, signalling ISRO’s rising technical sophistication in supporting numerous house missions. The twin radar payload aboard NISAR will make use of SweepSAR know-how for high-resolution, all-weather, day-and-night imaging of the Earth’s floor with a large swath of 242 kilometres.
The Union Minister additionally underlined the significance of Earth remark missions within the context of local weather resilience and sustainable improvement. “Missions like NISAR are no longer confined to scientific curiosity — they are instrumental in planning, risk assessment, and policy intervention. As climate change impacts intensify, timely and accurate data from satellites like NISAR will be indispensable for governments to act proactively,” he mentioned.
While the mission has seen an extended gestation interval of over a decade and a joint funding exceeding $1.5 billion, the payoff when it comes to world utility and technological development is anticipated to be transformative. The launch of NISAR is being intently watched by house companies, environmental researchers, and policymakers worldwide.
As the countdown to July 30 begins, Dr Jitendra Singh reiterated that India’s house program underneath the steering of Prime Minister Modi is steadily transitioning from conventional utility-based missions to those who place the nation as a information contributor to the worldwide commons. “NISAR is not just a satellite; it is India’s scientific handshake with the world,” he mentioned.
