SIR-C/X-SAR (Shuttle Imaging Radar-C / X-Band Synthetic Aperture Radar)

How US-Indian NISAR Satellite Will Offer Unique Window on Earth

A Q&A with the lead U.S. scientist of the mission, which will track changes in everything from wetlands to ice sheets to infrastructure damaged by natural disasters. The upcoming U.S.-India NISAR (NASA-ISRO Synthetic Aperture Radar) mission will observe Earth like no mission before, offering insights about our planet’s ever-changing surface.
