Summary:
- NASA and the Indian Space Research Organization (ISRO) have successfully launched a joint satellite mission called NISAR (NASA-ISRO Synthetic Aperture Radar) that can observe and measure changes in Earth's surface.
- The satellite has sent back its first radar images of Earth's surface, which will help scientists study natural disasters, climate change, and other important environmental processes.
- NISAR is the first-of-its-kind satellite that will use two different radar frequencies to provide a comprehensive view of the planet, allowing researchers to better understand the complex interactions between Earth's systems.
