A joint NASA‑ISRO satellite has given the world a fresh look at the Mississippi River Delta, capturing rivers, forests, cities, and farmland even under thick clouds. The image, taken on November 29, 2025, by the NISAR (NASA‑ISRO Synthetic Aperture Radar) mission, showcases the satellite’s unique ability to “see” through weather that would block regular cameras.
Unlike traditional imaging, NISAR uses radar waves to map the land, making every detail, from dense forests to urban streets, visible regardless of rain or clouds. Color coding in the radar image distinguishes forests, buildings, and farmland, showing how each reflects radar signals differently.
Landmarks like New Orleans, Baton Rouge, and Lake Pontchartrain are clearly visible, along with the Lake Pontchartrain Causeway, the world’s longest continuous bridge over water. Agricultural fields, wetlands, and urban areas appear in vibrant colors, painting a living portrait of the delta.
Since its launch from India on July 30, 2025, NISAR has been observing Earth every 12 days. Its data promise benefits beyond stunning imagery, helping scientists monitor ecosystems, crops, infrastructure, and respond to natural disasters.
The mission team plans to release thousands of NISAR data products for public access by late February, allowing researchers worldwide to explore this cloud‑piercing technology and its potential for understanding our changing planet.
