• NASA-ISRO Radar Mission Peers Through Clouds to See Mississippi River Delta This image captured by NISAR’s L-band SAR instrument on Nov. • 29, 2025, shows the cities of New Orleans and Baton Rouge, the Mississippi River, Lake Pontchartrain, and a range of wetlands, farmlands, and populated areas. • The colors indicate different types of land cover. • 29, 2025, image from NISAR’s L-band SAR instrument features labels noting cities and geographic features of the Mississippi River Delta region. • Colors indicate types of land cover, such as healthy forests (bright green), thinned tree populations (yellow-and-magenta hues), and tall crops (bright magenta). • A new image from the NISAR mission shows off the satellite’s ability to reveal details of Earth’s surfaces.

Article Summaries:

  • NASA and India’s ISRO have released a new L‑band synthetic aperture radar (SAR) image of the Mississippi River Delta, demonstrating the NISAR satellite’s ability to see through clouds. Captured on Nov. 29, the image shows New Orleans, Baton Rouge, Lake Pontchartrain, and surrounding wetlands, forests, and farmland, with color coding indicating different land‑cover types. The radar’s 24‑centimeter wavelength allows it to penetrate cloud cover and detect vegetation, buildings, and crop conditions-useful for monitoring ecosystems and agricultural progress. NISAR is preparing to make thousands of data files publicly available in late February, following a preliminary release of sample data.
