NEW DELHI: Excitement is building as NASA reveals the anticipated launch of the NISAR satellite, the most sophisticated Earth observation satellite ever created, now scheduled for March 2025. This groundbreaking project is a collaborative effort between NASA and ISRO, having previously aimed for a 2024 launch. However, the mission faced some unexpected technical hurdles.
Weighing in at 2.8 tonnes, NISAR will take off from India’s Satish Dhawan Space Centre, located on the southeastern coastline. After a decade of development, this satellite boasts an impressive dual-frequency radar system, incorporating NASA’s L-band at 1.25 GHz and ISRO’s S-band at 3.20 GHz, which will provide exceptionally precise data.
NISAR is set to scan most of the Earth’s land and frozen areas approximately every 12 days. It will monitor vital changes such as ecosystem dynamics, transformations in land and sea ice, as well as geological shifts. With its high-resolution imaging capabilities, researchers will gain deeper insights into climate change, disaster readiness, and resource management.
Valued at over Rs 5,800 crore, this mission highlights the power of international collaboration in space initiatives. By leveraging the strengths of both NASA and ISRO, the NISAR satellite promises to yield invaluable data that will aid in understanding our planet and addressing its urgent environmental challenges.
NISAR Satellite: A Game-Changer in Earth Observation Set for Launch in 2025
The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite represents a significant advancement in Earth observation technology, with its launch now targeted for March 2025. Originally scheduled to debut in 2024, the mission faced some technical challenges that have resulted in this new timeframe. Developed through a groundbreaking collaboration between NASA and the Indian Space Research Organisation (ISRO), NISAR is poised to become the most sophisticated Earth observation satellite to date.
Key Features and Specifications
Weighing approximately 2.8 tonnes, NISAR will be launched from the Satish Dhawan Space Centre in India. The satellite is equipped with a state-of-the-art dual-frequency radar system, utilizing NASA’s L-band radar at 1.25 GHz and ISRO’s S-band radar at 3.20 GHz. This unique configuration enables NISAR to capture remarkably detailed data, which will be crucial for numerous applications.
