The joint ISRO-NASA Earth observation satellite NISAR has successfully launched from the Satish Dhawan Space Centre in Sriharikota aboard India’s largest rocket, the GSLV Mk II. The 2,392 kg satellite will enter an 8–10 day deployment phase followed by 65 days of engineering tests. NISAR, equipped with L-band (NASA) and S-band (ISRO) synthetic aperture radars, will map Earth's surface every 12 days with high precision, detecting even slight movements. The mission, 10 years in the making, will help monitor earthquakes, landslides, and climate change, with special focus on Antarctica and global vegetation. Former ISRO chief K Sivan called it “a breakthrough.”
