The indian Space Studies Employer (ISRO) has entered the very last section of preparations for the NASA-ISRO Synthetic Aperture Radar (NISAR) venture, a collaboration set to revolutionize Earth remark.
To begin with, deliberate for 2024, the launch faced multiple delays due to technically demanding situations, inclusive of overheating risks within the satellite's 12-meter radar antenna reflector.
The element was shipped lower back to NASA's Jet Propulsion Laboratory (JPL) in 2024 for a reflective coating improvement to mitigate temperature worries for the duration of deployment.
After rigorous retesting, the satellite became fully integrated at ISRO's Bengaluru facility by way of october 2024. NASA's C-130 plane transported crucial hardware to india in a multi-leg adventure, with the very last assembly finished by january 2025.
The spacecraft has since been shipped to the satish dhawan space centre (SDSC) in Sriharikota, where isro is now engaging in pre-launch tests.
ISRO Chairman V. Narayanan currently indicated an upcoming 2025 release window during a meeting with Science minister Jitendra Singh.
The Geosynchronous Satellite Launch Vehicle (GSLV) Mark II's 2nd stage became flagged off to Sriharikota on april 26, 2025, signaling superior release campaign sports.
Nisar will hire dual-band radar (L-band and S-band) to scan the Earth's surface every 12 days, detecting sub-centimeter changes in landforms, ice sheets, and ecosystems. Its high-decision data will aid disaster management, weather research, and infrastructure monitoring. "Nisar will measure Earth's surface adjustments weekly, with every pixel masking 1/2 a tennis courtroom," said nasa JPL undertaking scientist Paul Rosen.
The project indicates deepening Indo-US space ties and positions isro as a key participant in global Earth science initiatives. If successful, Nisar's datasets could remodel expertise of crustal deformations, glacier dynamics, and carbon cycle fluctuations.
With the GSLV now at SDSC and payload integration underway, isro is set to supply one of 2025's most expected space missions, pending final agency clearances.
