   What is Nisar satellite & how does it work?

   • This radar imaging satellite will monitor changes in the Earth’s surface associated with the movement of the crust and ice cover. NISAR has two Synthetic Aperture Radars (SARs) onboard, an L-band (L-SAR) and an S-band (S-SAR), and will be the first satellite to use two different radar frequencies.

   Where did NASA's Nisar satellite come from?

   • The payload arrived from NASA’s Jet Propulsion Laboratory in Southern California in March, while the bus was built at the ISRO facility. Built on opposite sides of the planet, the NISAR satellite will deepen understanding of climate change, deforestation, glacier melt, volcanoes, earthquakes, and more.
