What is the NASA NISAR satellite and what has it discovered in Antarctica?
AI

The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is a collaborative Earth-observing mission between NASA (National Aeronautics and Space Administration) and ISRO (Indian Space Research Organisation) 10. Launched to monitor Earth's changing ecosystems, ice masses, and land surface, NISAR uses advanced radar technology to provide detailed images of our planet 10.

Key Features of the NISAR Satellite

NISAR is equipped with two primary Synthetic Aperture Radar (SAR) instruments:

  • L-band SAR: Operates at a 24 cm wavelength 10.
  • S-band SAR: Operates at a 9.4 cm wavelength 10.

These instruments allow NISAR to penetrate clouds and vegetation, and to operate day and night, providing high-resolution data on Earth's surface changes 10. The mission's coverage extends from near the South Pole to 77.5 degrees north latitude, enabling global monitoring of land deformation, ice flow, and surface changes 6.

NISAR's primary science operations are planned for three years, with potential for extended operations 9. All NASA synthetic aperture radar data, including NISAR's L-band products, are openly available to the public and hosted at the Alaska Satellite Facility Distributed Active Archive Center 610.

NISAR's Recent Discovery in Antarctica: The "Hummingbird" Pattern

In July 2026, scientists began accessing data from NISAR's powerful radar instruments, leading to a significant revelation in Antarctica 2. NISAR captured striking radar images of the Antarctic landscape that revealed a unique "hummingbird" pattern hidden beneath the ice 457.

Details of the Discovery

  • Location: The image focuses on Nunatak Zaterjavshijsja, a mountaintop in East Antarctica that protrudes from a stream of ice flowing northeast towards the ocean 18.
  • Imaging Technology: The "hummingbird" pattern was generated using measurements collected by NISAR's L-band instrument 7. This L-band radar is particularly effective at observing changes in ice sheets and glaciers, as it can penetrate the ice to reveal underlying structures and movement 13.
  • Significance: This discovery offers scientists a novel way to study how ice moves in one of Earth's most remote regions 3. The detailed radar images provide unprecedented insights into the dynamics of Antarctic ice and glaciers, which is crucial for understanding the impacts of climate change on sea level rise 67.

The "hummingbird" pattern is a visual representation of complex ice fractures and movements, providing valuable data for glaciologists and climate scientists 6. This new data from NISAR is expected to enhance our understanding of glacial behavior and the overall health of the Antarctic ice sheet 3.
