About NISAR:
NISAR is the only dual-frequency satellite, using an L-band (NASA) as well as S-band (ISRO) radars. It will be monitoring:
Dynamics of the Ice Sheet in Greenland and Antarctica
Earthquakes, volcanoes, landslides
The forest biomass and wetlands and agriculture
Sea-ice and surface changes to the ocean
The mission will provide open and free data to researchers around the world.
Mission Highlights:
Satellite Name: NISAR (NASA ISRO Synthetic Aperture Radar)
Launcher: GSLV-F16 (ISRO)
Liftoff Time: July 30, 2025
Orbit: 747 km Sun-synchronous
Mission Life 5 years
