Image: NISAR views Mount St. Helens
Why it matters: NISAR's L-band SAR instrument provides continuous, all-weather monitoring of Earth's surface for scientists.
- NISAR, a joint U.S.-Indian Earth satellite, successfully imaged Mount St. Helens through dense cloud cover.
- The L-band SAR instrument on NISAR is specifically designed to peer through clouds, enabling clear surface imaging even on overcast days.
- The image of Mount St. Helens was extracted from a larger swath of the Pacific Northwest, indicating the satellite's wide-area scanning capabilities.
The U.S.-Indian Earth satellite NISAR captured a detailed image of Mount St. Helens on November 10, 2025, demonstrating its L-band SAR instrument's capability to penetrate cloud cover and view the Earth's surface. This image was part of a broader scan of the Pacific Northwest, highlighting the satellite's advanced imaging technology.
