Key PointsNISAR satellite

• An Earth-observation satellite (NISAR) jointly developed by the National Aeronautics and Space Administration (NASA) and Indian Space Research Organisation (ISRO).
• The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite will provide important information on the Earth's crust, ice sheets, and ecosystems.
• It has been built by space agencies of the US and India under a partnership agreement signed in 2014.
• The 2,800 kilograms satellite consists of both L-band and S-band synthetic aperture radar (SAR) instruments, which makes it a dual-frequency imaging radar satellite.
• While NASA has provided the L-band radar, GPS, a high-capacity solid-state recorder to store data, and a payload data subsystem, ISRO has provided the S-band radar, the GSLV launch system, and spacecraft.
• Another important component of the satellite is its large 39-foot stationary antenna reflector.
