ISRO Unveils Indo-French TRISHNA Mission for Earth Observation (GS Paper 3, Science & Tech)
Introduction:
The Indian Space Research Organisation (ISRO) has revealed details about the collaborative Indo-French project, TRISHNA (Thermal Infra-Red Imaging Satellite for High-Resolution Natural Resource Assessment).
This joint mission aims to monitor surface temperature and water management across the globe, providing crucial data for climate impact assessments and resource management.
About the Project:
TRISHNA comes at a critical juncture, with both India and Europe experiencing extreme heat events.
The mission focuses on evapotranspiration monitoring to measure water evaporation from land and plants, offering insights into climate impacts on Earth's surface.
Mission Objectives:
TRISHNA will study water presence, concentrations, and dynamics, including melting glaciers, to quantify land water usage patterns.
Additionally, it will monitor thermal anomalies, urban heat islands, and other parameters related to surface heat emission.
The satellite will also analyze atmospheric aerosols, water vapor, and cloud dynamics worldwide.
Payloads and Parameters:
The satellite will carry two primary payloads: the Thermal Infra-Red (TIR) payload, provided by the French space agency CNES, and the Visible Near Infrared-Red Short Wave Infrared-Red (VNIR-SWIR) payload developed by ISRO.
These payloads will map surface temperature and reflectivity, respectively, aiding in the measurement of Earth's biophysical and radiation budget variables.
Expected Benefits:
TRISHNA aims to enhance remote sensing technology, crucial for monitoring Earth's surface and mitigating climate change impacts.
The mission's data will address critical water and food security issues, facilitating the development of sustainable policies for watershed management, agro-industries, and farming communities in India.
Additionally, its high-resolution imaging capability will improve understanding of Earth's natural processes, aiding global climate change mitigation efforts.
Conclusion:
The TRISHNA mission represents a significant collaboration between India and France in harnessing satellite technology for Earth observation and climate monitoring.
With its advanced payloads and ambitious objectives, TRISHNA is poised to contribute valuable insights into global environmental challenges, paving the way for informed decision-making and sustainable resource management practices.
