NASA and ISRO Join Forces for an Innovative Earth Observation Mission
In an exciting collaboration, NASA and the Indian Space Research Organisation (ISRO) are preparing to launch the groundbreaking NISAR satellite in March 2025. This mission, with an impressive budget of around ₹5,000 crore, signifies a new era in international space efforts focused on Earth monitoring.
The NISAR satellite, weighing 2.8 tons, is engineered to track changes across the planet with extraordinary accuracy. It will provide detailed scans of nearly all terrestrial and glacial regions every 12 days, unveiling critical information about ecosystems, land changes, and ice dynamics. This state-of-the-art satellite utilizes the advanced Synthetic Aperture Radar (SAR) technology, which allows it to generate high-resolution imagery in darkness and poor weather conditions. It can detect surface shifts as small as one inch and penetrate thick vegetation for extensive mapping.
Equipped with dual-frequency radar—NASA’s L-band and ISRO’s S-band—the satellite promises unmatched data precision. The launch will take place aboard the ISRO’s GSLV Mk-II rocket from the Satish Dhawan Space Centre, reaching an operational altitude of 747 km in a sun-synchronous orbit, with a mission life of three years.
NISAR’s data is anticipated to have extensive applications, including monitoring climate variations and geological hazards. After overcoming technical hurdles, including those associated with its large radar antenna, NISAR is set to make a meaningful impact on global scientific understanding.
Exciting Collaboration: NASA and ISRO’s NISAR Satellite Brings New Era of Earth Monitoring
Introduction
In a significant advancement for global Earth observation efforts, NASA and the Indian Space Research Organisation (ISRO) are set to launch the NISAR satellite in March 2025. With a budget of approximately ₹5,000 crore, this ambitious project signifies a transformative approach to monitoring our planet’s health and changes.
