Summary
NISAR (NASA-ISRO Synthetic Aperture Radar) launched on an Indian Space Research Organization GSLV Mk. II from Satish Dhawan Space Centre Second Launch Pad, Satish Dhawan Space Centre, India on July 30, 2025 at 12:10 UTC. It was Indian Space Research Organization's 96th launch, 3rd this year and humanity's 7,017th orbital launch attempt. It was the 12th GSLV Mk. II flight and the 2nd this year. The payload was bound for Sun-Synchronous Orbit (SSO). NISAR, one of 2 catalogued objects, reached a 741 × 757 km orbit inclined 98.4°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
The NASA-ISRO Synthetic Aperture Radar, or NISAR satellite, will use advanced radar imaging to map the elevation of Earth's land and ice masses 4 to 6 times a month at resolutions of 5 to 10 meters. It is designed to observe and measure some of the planet's most complex natural processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides. Under the terms of the agreement, NASA will provide the mission's L band synthetic aperture radar (SAR), a high-rate telecommunication subsystem for scientific data, GPS receivers, a solid-state recorder, and a payload data subsystem. ISRO will provide the satellite bus, an S band synthetic aperture radar, the launch vehicle, and associated launch services.

US-India Satellite Captures Time-lapse Video of Volcanic EruptionLike tendrils on a vine, lava spreads out from the northern crater of Krasheninnikov, a volcano pair on the Pacific coast of Russia’s Kamchatka Peninsula. On July 30, 2025, an 8.8-magnitude earthquake had struck in the nearby ocean, apparently jolting one of the two volcanoes awake. A few days later, for the first time in […]
NISAR’s L-Band Radar Reveals ‘Hummingbird’ in AntarcticaDescription Data from the Earth-orbiting U.S.-India NISAR (NASA-ISRO Synthetic Aperture Radar) satellite’s L-band radar was used to produce an image of Nunatak Zaterjavshijsja — a mountaintop in East Antarctica — poking out amid a stream of ice flowing northeast to the ocean. The obstruction causes stresses in the ice, heavily fracturing the surrounding surfaces with […]
US-India Satellite Delivers Data, Reveals ‘Hummingbird’ in AntarcticaAs of July 20, the public can access data from the two powerful radar instruments aboard the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite. Teams in the United States and India will release files processed from the satellite’s L-band and S-band radars on an ongoing basis, helping researchers and other users track the movement of Earth’s […]
