US-India satellite delivers data, reveals 'hummingbird' in Antarctica

As of July 20, the public can access data from the two powerful radar instruments aboard the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite. Teams in the United States and India will release files processed from the satellite's L-band and S-band radars on an ongoing basis, helping researchers and other users track the movement of Earth's land and ice masses, monitor changes in ecosystems like forests and wetlands and respond to natural hazards such as landslides and earthquakes.
