On Wednesday, July 30, 2025, India and the U.S. celebrated their first space partnership with the successful launch of a Geosynchronous Satellite Launch Vehicle (GSLV) rocket. This rocket successfully placed an earth observation satellite, which was developed collaboratively by both space agencies, into a precise orbit.

ISRO’s GSLV F-16 launched the NISAR –  NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, into the planned Sun Synchronous Polar Orbit (SSPO) after a flight lasting about 19 minutes and covering approximately 745 km.

ISRO confirmed that the GSLV “successfully injected NISAR in designated orbit”.

“The GSLV-F16 rocket has successfully and accurately placed the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, which weighs 2,393 kg, into its designated orbit”, stated Dr. V. Narayanan, Secretary of the Department of Space(ISRO).

“All systems of the vehicle functioned normally, just as we anticipated and predicted”, he remarked.

Dr. V. Narayanan mentioned that the successful launch of NISAR “showcased international collaboration” between the two space agencies, and the data gathered by NISAR will be “beneficial for scientific communities worldwide”.

The NISAR satellite is set to scan the Earth, delivering all-weather, day-and-night data every 12 days, which will support a variety of applications. The main goals of the NISAR mission include examining land and ice deformation, studying land ecosystems, and exploring oceanic regions that are of mutual interest to the scientific communities in the United States and India.
