TRISHNA Mission

Key notes

  • TRISHNA is a joint Earth-observation mission of ISRO and France’s CNES.
  • The name expands to Thermal infraRed Imaging Satellite for High-resolution Natural resource Assessment.
  • It will study Earth’s land and coastal surfaces through high-resolution thermal imaging.

  • Important applications:

    • Crop-water stress.
    • Irrigation management.
    • Evapotranspiration.
    • Urban heat islands.
    • Water-resource monitoring.
    • Glaciers.
    • Climate change.

  • It combines:

    • Thermal infrared instruments from CNES.
    • Optical sensors from ISRO.
  • It is expected to provide frequent observations of land-surface temperature.
  • It supports climate-resilient agriculture and water governance. PIB describes TRISHNA as a planned mission for high-resolution thermal imaging with applications in agriculture, water and climate monitoring.
