NISAR – UPSC Prelims

  • NISAR stands for NASA ISRO Synthetic Aperture Radar Mission
  • This satellite will be able to detect the earth’s surface movement as small as 0.4 inches over an area.
  • It will be a three-year mission. It will scan the globe including Earth’s land, ice sheets, and sea ice, every 12 days during its mission.
  • Slated to launched in 2022
  • NISAR is a dual frequency (L & S Band) Radar Imaging Satellite. It will be the first radar imaging satellite to use dual frequency.
  • Will be launched in a Sun Synchronous Low -Earth
  • It is designed to observe and take measurements of some of the planet’s most complex processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earth quakes, tsunamis, volcanoes  and landslides.
  • The satellite is likely to be launched from India aboard an Indian launch vehicle.
  • Applications:
    • NISAR would provide info about a place more frequently. For Ex. If the present satellite take 23 to 25 days to revisit a particular spot and give the next round of info about it, NISAR would provide the repeat info in two to five days.
  • Objectives of the Mission: The primary goals of the mission includes:
    • Tracking subtle changes in the Earth’s surface
    • Spotting warning signs of imminent volcanic eruptions
    • Helping to monitor groundwater supplies and
    • Tracking the rate at which ice sheets are melting.
