About NISAR
- NISAR, an earth observation satellite, was jointly developed by NASA and ISRO eight years ago in 2014 as a demonstration of radar’s capability as a science tool for studying the Earth’s dynamic land and ice surfaces in greater detail.
- This Low Earth Orbit observatory carries L and S dual-band Synthetic Aperture Radar (SAR) which uses the Sweep SAR technique to achieve large swaths with high-resolution data. The SAR payloads and the spacecraft bus together form an observatory mounted on an Integrated Radar Instrument Structure (IRIS).
- ISRO will use NISAR for various purposes, including agricultural mapping and identifying landslide-prone areas.
★★ Current Affairs Quiz ★★
- NISAR will provide significant information on the Earth’s surface changes, natural hazards, and ecosystem disturbances, advancing our understanding of Earth system processes and climate change.
- The mission will help manage natural disasters such as earthquakes, tsunamis, and volcanic eruptions, providing faster response times and better risk assessments.
- NISAR data will be useful in improving agriculture monitoring and management, including monitoring of oil spills, urbanization, and deforestation.
- NISAR will help monitor and understand the impacts of climate change on the Earth’s land surface, such as melting glaciers, sea-level rise, and changes in carbon storage.
