- The NASA-Indian Space Research Organisation (ISRO) Synthetic Aperture Radar (NISAR) satellite mission cost over 1.5 billion USD.
- NISAR carries two radars, L-band from NASA and S-band from ISRO, operating together to scan Earth’s surface in detail.
- It will monitor land changes, ice sheets, wildfires, and more with a 12-meter dish from 747 km altitude every 12 days.
- It can detect vertical ground movements as small as 1 centimetre, helping predict disasters like earthquakes and landslides.
- ISRO contributed the satellite bus radar and launch services, marking a key Indo-US collaboration in space science.
