Now US NISAR Satellite is of ISRO
The Indian Space Research Organisation (ISRO) has received the NASA-ISRO SAR (NISAR) satellite from the U.S. space agency. A US Air Force C-17 aircraft carrying the NASA-ISRO synthetic aperture radar (NISAR) has landed in Bengaluru.
NISAR Satellite- All About
- NISAR was envisioned by NASA and ISRO eight years ago in 2014 as a powerful demonstration of the capability of radar as a science tool and help us study Earth’s dynamic land and ice surfaces in greater detail than ever before.
- NISAR is a Low Earth Orbit observatory jointly developed by NASA and ISRO.
- NISAR carries L and S dual-band Synthetic Aperture Radar (SAR), which operates with the Sweep SAR technique to achieve large swaths with high-resolution data. The SAR payloads mounted on Integrated Radar Instrument Structure (IRIS) and the spacecraft bus are together called an observatory.
- NISAR will be used by ISRO for a variety of purposes including agricultural mapping, and landslide-prone areas.
- NISAR will provide a wealth of data and information about the Earth’s surface changes, natural hazards, and ecosystem disturbances, helping to advance our understanding of Earth system processes and climate change.
- The mission will provide critical information to help manage natural disasters such as earthquakes, tsunamis, and volcanic eruptions, enabling faster response times and better risk assessments.
- NISAR data will be used to improve agriculture monitoring and management, such as monitoring of oil spills, urbanization, and deforestation.
- NISAR will help to monitor and understand the impacts of climate change on the Earth’s land surface, including melting glaciers, sea-level rise, and changes in carbon storage.
The satellite is expected to be launched in 2024 from Satish Dhawan Space Centre in Andhra Pradesh, into a near-polar orbit. The satellite will operate for a minimum of three years. It is a Low Earth Orbit (LEO) observatory. NISAR will map the entire globe in 12 days.
