About TRISHNA

TRISHNA is a future high-resolution space-time mission in the thermal infrared (TIR) led jointly by the French (CNES) and the Indian (ISRO) space agencies for a launch planned in 2025.
The scientific objectives guiding the definition of the mission are, in order of priority, the monitoring of the water status and of the stress of continental ecosystems, the monitoring of coastal and inland waters, the urban environment, and applications to the solid Earth, the cryosphere and the atmosphere.
TRISHNA will be positioned on a polar orbit at an altitude of 761 km, providing a revisit of 3 passages over 8 days with global coverage.
