NASA and ISRO are collaborating on the NISAR (NASA-ISRO Synthetic Aperture Radar) project to study the surface of the planet Earth in a way that no other mission has done before, NASA stated in a press release.
“The NISAR mission will track changes in everything from wetlands to ice sheets to infrastructure damaged by natural disasters”, NASA said.
Coming soon: NISAR 🛰️

The @NASA–@ISRO mission will track changes in everything from wetlands to ice sheets to infrastructure damaged by natural disasters. Paul Rosen, the lead U.S. scientist on the mission, discusses what sets NISAR apart: https://t.co/qgynEEdxa3 pic.twitter.com/ZnvNlPqOTn
NISAR is a first-of-a-kind dual-band radar satellite that will measure land deformation from earthquakes, landslides, and volcanoes, producing data for science and disaster response. It will also study how much glaciers and ice sheets are expanding, or receding, how forests and wetlands across the world are changing, and much more.
NISAR will be the first Earth-observing satellite with two kinds of radar: an L-band system with a 10-inch (25-centimeter) wavelength and an S-band system with a 4-inch (10-centimeter) wavelength, NASA scientist Paul Rosen informed in the press release.
The satellite, considered to be one of the world’s most advanced and most expensive, is scheduled to launch around March 2025.
