NISAR
  • An Earth-observation satellite, is being jointly developed by the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO).
  • 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.
  • It is expected to be launched in January 2024 from Satish Dhawan Space Centre 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.
Benefits
  • NISAR will be the first radar of its kind in space to systematically map Earth, using two different radar frequencies (L-band and S-band) to measure changes in our planet's surface less than a centimeter across.
  • 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 management and food security by providing information about crop growth, soil moisture, and land-use changes.
  • The mission will provide data for infrastructure 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.
