Detailed technical reviews and integration processes are underway, and the leadership is optimistic about an on-schedule liftoff before July closes.NISAR represents the most expensive satellite project undertaken by Isro and Nasa, with a combined cost of $1.5 billion. It is the world's first Earth observation mission to utilise dual-frequency radar technology, blending Nasa's L-band and Isro's S-band systems.After Isro's Geosynchronous Launch Vehicle (GSLV) pushes this $1.5 billion mission into orbit, Nisar will unfold its 13-metre diameter radar antenna like an origami masterpiece to begin a systematic scan of Earth's entire surface.Set to orbit the planet every 12 days, NISAR will offer three-dimensional, centimetre-level mapping of Earth's land and ice surfaces, providing critical data for monitoring ecosystems, natural hazards, and climate impacts.Nisar's mission is to provide unprecedented coverage of the planet. For three years, it will monitor the Earth's land surface and interior for subtle changes due to earthquakes, volcanoes, and human activities; its cryosphere for unprecedented melting of polar ice sheets and glaciers caused by climate change; and its coastal and ground waters for impacts of floods and aquifer usage.
A key highlight of the mission is its commitment to open science. (Photo: Isro)
A key highlight of the mission is its commitment to open science: data collected by NISAR will be made freely available to researchers and governments worldwide, making it a global asset in tracking natural disasters, infrastructure changes, and environmental transformations.With only the comprehensive final reviews left to complete, the anticipation surrounding the NISAR mission is building rapidly.Once launched, NISAR will cement India's role as a frontline player in international space collaboration and Earth science advancement.- EndsMust Watch

Nisar mission to benefit global community in earth observation: Isro chief
Nisar mission TIRUCHIRAPALLI: The Nisar mission , jointly developed by Isro and the national aeronautics and space administration ( Nasa ), would significantly benefit the global community in earth observation , Isro chairman V Narayanan said here on Saturday. The GSLV-F16/Nisar Mission is the result of over a decade of robust technical cooperation between the two teams of Isro and Nasa-jet propulsion laboratory, US. According to Isro , the mission in itself has got a lot of firsts -- it is the first mission to carry dual-band radar satellite, a GSLV rocket will carry a satellite to be placed in Sunsynchronous Orbit (unlike PSLV rockets) and it is the first Isro-Nasa Earth Observation Mission. Nisar, which is short for Nasa-Isro synthetic aperture radar (Nisar), would help scientists comprehensively monitor Earth's land and ice surfaces, building a detailed record of large and small changes over time. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Jakarta: Unsold Sofas May Be at Bargain Prices (Prices May Surprise You) Sofas | Search Ads Search Now Undo The mission would also be crucial in helping the scientific community to gain a better understanding of the processes involved during natural calamities like earthquakes, volcanic eruptions and landslides. As per the collaboration between Isro and Nasa, the rocket would carry a unique earth observation satellite with a dual-frequency radar provided by Nasa's L-Band and Isro's S-Band. The Radar would use Nasa's 12 metre mesh reflector antenna that has been integrated into ISRO's I3K satellite bus. Speaking to reporters here, Narayanan said, "Nasa-Isro Synthetic Aperture Radar (Nisar) satellite launch will be done using our GSLV-MkII vehicle ( GSLV-F16 ). The payloads are jointly realised by Isro and Jet Propulsion Laboratory (JPL), USA. This satellite is going to be useful for the global community in earth observation and disaster mitigation areas." "The Mission is also a very, very important as Isro would be making the 102nd launch from Indian soil that is targeted on July 30, 5.40 pm (from Sriharikota)", Narayanan also the secretary, department of space, said. Weighing 2,392 kg, the satellite would observe the earth with a swath of 242 km and high spatial resolution, using SweepSAR technology for the first time, Isro said. The satellite would scan the entire globe and provide all weather, day and night data at 12-day interval and enable a wide range of applications. The radar can detect even small changes in the Earth's surface such as ground deformation, ice-sheet movement and vegetation dynamics. Some of the other applications are ship detection, shoreline monitoring, storm characterisation, changes in soil moisture, mapping and monitoring of surface water resources and disaster response, the space agency said. Nisar would provide scientific information about the Earth's processes and it would study key changes in Earth's land and ice. The mission would also be more powerful than previous Synthetic Aperture Radar missions as it will monitor parts of Earth which are not previously covered.

NISAR mission to benefit global community in earth observation: ISRO chief
ISRO chairman V Narayanan announced the GSLV-F16/NISAR mission, a collaborative effort between ISRO and NASA, set to launch on July 30th. This mission, carrying a dual-band radar satellite, marks several firsts, including being the first ISRO-NASA Earth Observation Mission. NISAR will monitor Earth's land and ice surfaces, aiding in understanding natural calamities and providing crucial data for various applications. Tired of too many ads?

Consistent effort key to India's growth in space technology, says ISRO chairman
India has made great strides in space technology and attained global leadership through sheer hard work and consistent effort, V. Narayanan, Secretary, Department of Space, and Chairman, Indian Space Research Organisation (ISRO), said in Tiruchi on Saturday. Addressing the 21st convocation of the National Institute of Technology–Tiruchi (NIT-T), Mr. Narayanan said that the upcoming NASA-ISRO Synthetic Aperture Radar (NISAR) mission on July 30 was testimony to India's growing stature in space technology. Speaking about Indian astronaut Group Captain Shubhanshu Shukla's journey to the International Space Station this year, Mr. Narayanan said: 'The original launch date was planned on June 11. On the morning of June 10, we understood that the Falcon rocket that was meant to take Shukla ji and three other astronauts to space, had a liquid oxygen leakage in the booster engine. Indians were the ones who raised it and ensured that the launch was called off later that day because we were not convinced by the rocket's safety. After the entire thing was corrected and validated to our satisfaction, the rocket lifted off on June 25. Every Indian and ISRO scientist can be proud that with our education system, our knowledge and ISRO's background, we could stop a launch to ensure the safety of astronauts.' Emphasising the significance of India's space research journey, he said the country launched its 100th space vehicle this year. 'From humble beginnings, India's space exploration has been built on a foundation of resilience and collaboration, steadily evolving into a programme that now plays a critical role in supporting and enhancing various aspects of human life,' he said. He urged the outgoing batch of students to take pride in their educational journey and utilise their knowledge to contribute towards society. In her address, G. Aghila, Director, NIT, TIruchi, said that the launch of the NIT-T Research and Innovation Hub (NITTRIH) and ongoing collaborations with ISRO through the Space Technology Incubation Centre underscored the institution's robust innovation ecosystem. Several international and industry partnerships were formed this year, she added. A total of 2,045 students received their degrees on Saturday. The President's Medal for the highest overall cumulative grade point average (CGPA) was awarded to M. Jayashree of B. Tech, Electronics and Communication Engineering. Institute medals were presented to nine one 23 five and one each of MCA, MBA, and M.A. graduands.
