Weighing 2,392 kg, NISAR is a singular Earth statement satellite tv for pc and the primary to watch 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 tv for pc bus.
It will observe earth with a swath of 242 km and excessive spatial decision, utilizing SweepSAR expertise for the primary time, in response to the area company.
It shall be launched from the Satish Dhawan Space Centre, Sriharikota.
“The Earth statement satellite tv for pc collectively developed by ISRO and NASA shall be despatched into area on July 30 by the GSLV-F16 rocket made in India,” Indian Space Research Organisation chairman V Narayanan mentioned.
It shall be launched at a distance of 740 km. It can take footage of the earth 24 hours a day in all climate situations and the satellite tv for pc can detect landslides, support in catastrophe administration and monitor local weather change, he mentioned whereas chatting with reporters on the airport in Chennai on Sunday (July 27, 2025) night time.
“The satellite tv for pc will profit India, the U.S. and the whole world… additionally it is essential for monitoring earth’s pure assets,” he added.
On Gaganyaan, India’s human spaceflight Mission, Narayanan mentioned a humanoid, known as Vyommitra, shall be despatched into area in December this yr. Once it proved to achieve success, two different uncrewed missions can be launched subsequent yr.
Following the success, the Gaganyaan Mission shall 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 tv for pc mission is scheduled for July 30, 2025, at 17:40 hrs from the Satish Dhawan Space Centre, Sriharikota.
As the primary joint Earth statement 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 area cooperation and in addition in ISRO’s total worldwide collaborations, he mentioned. The mission shall be launched aboard India’s GSLV-F16 rocket.
Mr. Singh, who has been monitoring the mission carefully, mentioned the launch displays the maturing of strategic scientific partnerships and India’s emergence as a reputable world participant in superior Earth statement techniques. While expressing his want to be bodily current in Sriharikota to witness the historic occasion, the Minister acknowledged that the continuing Parliament session could maintain him again in Delhi.
“This mission is not only a few satellite tv for pc launch–it is a second that symbolises what two democracies dedicated to science and world welfare can obtain collectively. NISAR won’t solely serve India and the United States however will even present essential information for nations all over the world, particularly in areas like catastrophe administration, agriculture, and local weather monitoring,” mentioned Dr Singh.
Mr. Singh additional famous that this mission lives as much as 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 every one information generated by NISAR shall be made freely accessible inside one to 2 days of statement and in close to real-time in case of emergencies. This democratisation of information is predicted to assist world scientific analysis and decision-making, particularly for creating nations that won’t have entry to related capabilities.
Notably, the NISAR mission is the primary time a GSLV rocket is getting used to put a satellite tv for pc in sun-synchronous polar orbit, signalling ISRO’s rising technical sophistication in supporting various area missions. The twin radar payload aboard NISAR will make use of SweepSAR expertise 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 statement missions within the context of local weather resilience and sustainable improvement. “Missions like NISAR are now not confined to scientific curiosity — they’re instrumental in planning, danger evaluation, and coverage intervention. As local weather change impacts intensify, well timed and correct information from satellites like NISAR shall be indispensable for governments to behave proactively,” he mentioned.
While the mission has seen a protracted 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 predicted to be transformative. The launch of NISAR is being carefully watched by area businesses, environmental researchers, and policymakers worldwide.
As the countdown to July 30 begins, Dr Jitendra Singh reiterated that India’s area program underneath the steering of Prime Minister Modi is steadily transitioning from conventional utility-based missions to those who place the nation as a data contributor to the worldwide commons. “NISAR is not only a satellite tv for pc; it’s India’s scientific handshake with the world,” he mentioned.
