NASA–ISRO NISAR Returns First Synthetic-Aperture Radar Images of Earth

The NASA–ISRO NISAR Earth-observing radar satellite has returned its first synthetic-aperture radar images, showing high-detail views of the Maine coast and North Dakota farmland. The imagery validates instrument performance as the joint mission approaches full science operations later this year.

Briefing

What Hype is tracking

  • NISAR is an operational-scale Earth science radar mission that will "scan the planet twice every 12 days" as part of a $1.5B program — its first images confirm the satellite is delivering usable SAR data ahead of full science operations.

  • Early high-detail coastal and agricultural imagery demonstrates the value of all-weather, day/night SAR for climate, disaster response and maritime/defence surveillance; this validation is directly relevant to other recent radar-satellite programmes focused on maritime domain awareness.
