TRISHNA or (Thermal infraRed Imaging Satellite for High-resolution Natural resource Assessment)[2][3] 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
[edit]The Mission was announced during bilateral talks between India and France in July 2023.[4][5] On 19 March 2024, TRISHNA received approval from both space agencies and a project team has been formed to finish developing the mission concept.[3][2] It is currently planned for a launch in 2026, aboard a PSLV rocket from Satish Dhawan Space Centre.[6][1] This marks the next collaboration in space between India and France following the Megha-Tropiques and SARAL satellites.
Instruments
[edit]Trishna aims to have a resolution of approximately 57 metres and a re-vist interval of about three days.[2][3] It would have two instruments, namely Visible and Near Infrared (VNIR)/Short Wave InfraRed (SWIR) sensor (VSWIR) and Thermal InfraRed instrument (TIR).[6]
