On July 30, 2025, ISRO and NASA successfully launched the NISAR satellite from Sriharikota, Andhra Pradesh. This landmark mission combines U.S. and Indian radar technologies to monitor Earth’s surface changes with unmatched accuracy, strengthening global climate and disaster response capabilities.

Key Points:

• The NISAR satellite was launched aboard the GSLV-F16 rocket at 5:40?pm IST from the Satish Dhawan Space Centre, marking a major milestone in Indo-U.S. space collaboration.
• It is the world’s first Earth observation satellite to carry dual-frequency synthetic aperture radars—NASA’s L-band and ISRO’s S-band—capable of detecting surface shifts as small as 1?cm.
• NISAR will orbit Earth at 743?km altitude, mapping land and ice every 12 days to study climate change, earthquakes, glacier loss, floods, and agricultural patterns.
• The mission, valued at approximately $1.5 billion, is jointly funded and developed by NASA and ISRO, reflecting strong bilateral ties in space science and technology.
• With its data set to be openly accessible, NISAR is expected to greatly aid researchers, policymakers, and emergency response teams across the globe.
