What happened:
On January 30, NASA and ISRO released a radar image from the NISAR mission showing the Mississippi River Delta, including New Orleans, Baton Rouge, and wetlands. The image penetrates cloud cover, and sample datasets are now available ahead of the full release in February.
Why it matters:
The L-band radar allows detailed mapping of land, vegetation, and infrastructure, supporting disaster response, agriculture, and environmental monitoring. NISAR, a joint NASA-ISRO mission, advances global Earth observation and climate research.
