India and France to launch Trishna satellite in 2027: PM Modi

The Prime Minister announced that India and France will jointly launch the TRISHNA satellite in 2027 to support global water and food security.

About TRISHNA

• TRISHNA stands for Thermal Infra-Red Imaging Satellite for High-resolution Natural Resource Assessment.
• It is a joint mission between the Indian Space Research Organisation and Centre National d’Études Spatiales.
• The mission reflects the growing India–France strategic partnership in space technology and climate action.
• The mission will generate high-resolution data for surface energy balance, water cycle studies, agricultural monitoring, drought assessment and Climate modelling.
• TRISHNA carries two primary payloads: Thermal Infra-Red (TIR) Payload developed by CNES and Visible–Near Infra-Red–Short Wave Infra-Red (VNIR–SWIR) Payload developed by ISRO

Objectives of the Mission:

• Monitor Earth’s surface temperature with high spatial and temporal resolution.
• Assess surface emissivity, biophysical, and radiation variables for surface energy budgeting.
• Quantify terrestrial water stress and water use through evapotranspiration monitoring.
• Improve understanding of the impacts of human-induced climate change.
• Support efficient water resource management.
• Monitor water quality and dynamics in coastal and inland water bodies.
• Contribute to global water and food security through improved natural resource assessment.
• Provides regional to global-scale observations of land surface processes.
