TRISHNA

TRISHNA or (Thermal infraRed Imaging Satellite for High-resolution Natural resource Assessment) is a planned cooperative joint satellite mission between the Indian Space Research Organisation (ISRO) of India  and Centre national d'études spatiales (CNES) of France.

History
The Mission was announced during bilateral talks between India and France in July 2023. On 19 March 2024, TRISHNA received approval from both space agencies and a project team has been formed to finish developing the mission concept. It is currently planned for a launch in 2025, possibly aboard a PSLV rocket from Satish Dhawan Space Centre. This marks the next collaboration in space between India and France following the Megha-Tropiques and SARAL satellites.

Instruments
Trishna aims to have a resolution of approximately 57 metres and a re-vist interval of about three days. It would have two instruments, namely Visible and Near Infrared (VNIR)/Short Wave InfraRed (SWIR) sensor (VSWIR) and Thermal InfraRed instrument (TIR).
