The 'NISAR' (NASA-ISRO Synthetic Aperture Radar) satellite, jointly developed by the indian Space Research Organization (ISRO) and the US Space Agency (NASA), was successfully launched into space today to study changes in the Earth's surface in detail. Since this satellite is capable of scanning the entire Earth in 12 days, it is expected to revolutionize global Earth science research. NISAR is a state-of-the-art radar imaging satellite that can detect even the smallest changes in the surface of the Earth's land and ice sheets. It uses two different frequency radars, L-band and S-band. Thus, changes in the Earth's surface can be measured with great precision.

The Nisar satellite, which uses synthetic aperture radar (SAR) technology, allows it to take high-resolution images without the use of a large antenna. Using radar signals, it can penetrate the Earth's surface and take images, even if there are clouds or darkness. Nisar, which orbits the Earth in a specific orbit, is designed to pass over the same area once every 12 days. This allows it to repeatedly scan and collect data on changes in the Earth's topography at specific intervals. Since the satellite's radar instruments have a wide field of view, it is possible to scan large areas at once and scan the entire Earth in a short period of time.

The Nisar mission will provide vital information on Earth’s environmental changes, natural disasters, melting glaciers, earthquakes, volcanic eruptions, and agricultural areas. This will be an invaluable tool for scientists and researchers to understand the effects of climate change, predict disasters, and manage disasters. It is also considered a major milestone in space cooperation between india and the United States.
