The distinctive Earth statement satellite NASA-ISRO Synthetic Aperture Radar (NISAR) will likely be launched by way of the GSLV-S16 on July 30, stated ISRO chairman V Narayanan.
Weighing 2,392 kg, NISAR is a singular Earth statement 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 area 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 stated.
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, assist in catastrophe administration and monitor local weather change, he stated 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 stated a humanoid, referred to as Vyommitra, will likely be despatched into area in December this 12 months. Once it proved to achieve success, two different uncrewed missions can be launched subsequent 12 months.
Following the success, the Gaganyaan Mission will likely be launched in March 2027 as Prime Minister Narendra Modi has stated.
‘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 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 likewise in ISRO’s total worldwide collaborations, he stated. The mission will likely be launched aboard India’s GSLV-F16 rocket.
Mr. Singh, who has been monitoring the mission carefully, stated the launch displays the maturing of strategic scientific partnerships and India’s emergence as a reputable international participant in superior Earth statement programs. 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,” stated Dr Singh.
Mr. Singh additional famous that this mission lives up to Prime Minister Narendra Modi’s imaginative and prescient of India changing into a ‘Vishwa Bandhu’–a international accomplice that contributes to the collective good of humanity.
A key function of the mission is that every one knowledge generated by NISAR will likely be made freely accessible inside one to two days of statement and in close to real-time in case of emergencies. This democratisation of information is predicted to assist international scientific analysis and decision-making, particularly for growing nations that will not have entry to related 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 area 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 statement 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 stated.
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 international utility and technological development is predicted to be transformative. The launch of NISAR is being carefully watched by area companies, environmental researchers, and policymakers worldwide.
As the countdown to July 30 begins, Dr Jitendra Singh reiterated that India’s area program below the steering of Prime Minister Modi is steadily transitioning from conventional utility-based missions to people 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 stated.
