Indo-French TRISHNA Mission

🛰️ 1. About the TRISHNA Mission

➡️ TRISHNA is a collaborative Earth-observation satellite mission between the Indian Space Research Organisation (ISRO) and France’s National Centre for Space Studies (CNES).

➡️ Its primary purpose is to use high-resolution thermal infrared imaging to assess natural resources and monitor the Earth’s surface.

➡️ The mission has been under conceptualisation and formalisation for approximately a decade, and has now reached the realisation stage, according to the report.

🤝 2. India–France Space Cooperation

➡️ TRISHNA is described as the third satellite developed jointly by India and France, following:

➡️ 🛰️ Megha-Tropiques: A joint mission focused on studying the water cycle and energy exchanges in the tropical atmosphere.

➡️ 🛰️ SARAL (Satellite with ARgos and ALtika): A joint oceanographic mission that measures ocean-surface height and studies ocean circulation.

➡️ TRISHNA reflects the continuing scientific and technological partnership between India and France in space research.

🌡️ 3. Significance of TRISHNA

➡️ 🌾 Agriculture: Thermal observations can help assess crop water stress and support irrigation planning.

➡️ 💧 Water management: Surface temperature and evapotranspiration measurements can help improve water-resource assessment.

➡️ 🌳 Ecosystem monitoring: Satellite observations can help study vegetation health and environmental changes.

➡️ 🌍 Climate research: High-resolution thermal data can support research on land-surface processes and climate-related impacts.

➡️ 📊 Natural-resource management: Better observations can support evidence-based planning for land, water and vegetation.
