🔆What is TRISHNA Mission?
✅Recently, the President of the French Space Agency, Centre National d’Etudes Spatiales (CNES), in an event spoke on a wide range of topics from celebrating 60 years of French-India space cooperation to the Gaganyaan and the TRISHNA missions.
✅The Thermal Infrared Imaging Satellite for High-resolution Natural Resource Assessment
(TRISHNA) mission a collaborative endeavor between the
Indian Space Research Organisation (Isro) the French Space Agency CNES.
📍
Objectives
✅It is engineered to deliver
high spatial and temporal resolution observations of Earth's surface
temperature, vegetation health, and water cycle dynamics.
✅It will also help in a comprehensive assessment of
urban heat islands, detection of thermal anomalies linked to volcanic activity and
geothermal resources, and precise monitoring of snow-melt runoff and glacier dynamics.
✅The mission will also provide
valuable data on aerosol optical depth, atmospheric water vapor, and cloud cover.
📍
Payloads: TRISHNA satellite is equipped with two primary payloads.
✅
The Thermal Infra-Red (TIR) Payload: It is provided by CNES, features a four-channel long-wave infrared imaging sensor capable of high-resolution surface temperature and emissivity mapping.
✅
The Visible - Near Infra-Red - Short Wave Infra-Red (
VNIR-SWIR) payload: It is
developed by ISRO, includes seven spectral bands designed for detailed mapping of surface reflectance of VSWIR bands for generating important biophysical and radiation budget variables.
✅The satellite will
operate in a sun-synchronous orbit at an altitude of 761 km, with a local time of 12:30 PM at the equator.
