TRISHNA Mission

ISRO's collaboration with the French space agency CNES  for the TRISHNA mission marks an exciting advancement in satellite technology and environmental monitoring. Scheduled for launch, TRISHNA (Thermal Infrared Imaging Satellite for High-resolution Natural Resource Assessment) will be equipped to capture high-resolution thermal infrared imagery. This capability is crucial for monitoring and assessing natural resources and environmental changes with greater precision.

Aim: The mission aims to enhance our understanding of various environmental factors, such as land surface temperature variations, vegetation health, and water resources. By providing detailed thermal imaging, TRISHNA will support more effective resource management and contribute valuable data for climate studies and natural disaster response.

About TRISHNA Mission
• It is designed to offer precise information about the Earth's land and sea temperatures. These metrics are vital for farming methods, such as monitoring urban heat and mitigating calamities.

Applications:

• Agriculture: By tracking temperature variations, TRISHNA helps optimize farming strategies, improve crop yields, and monitor drought conditions.
• Urban Heat: It aids in assessing and managing heat islands in urban areas, contributing to better city planning and public health strategies.
• Disaster Management: Accurate temperature data supports early warning systems and disaster response efforts, helping to mitigate the impacts of extreme weather events.

Global Initiatives:

• GEOGLAM: TRISHNA's data supports the Global Agricultural Monitoring initiative, which aims to provide timely and accurate information on crop conditions and agricultural practices worldwide.
• UN Sustainable Development Goals: The mission contributes to goals related to climate action, sustainable cities, and responsible consumption by offering insights into temperature trends and environmental changes.
• Global Water Watch: By monitoring water temperatures, TRISHNA helps in managing and protecting water resources on a global scale.

The TRISHNA satellite is equipped with two advanced payloads, each serving distinct purposes:

1. Thermal Infra-Red (TIR) Payload: Provided by the French space agency CNES, this payload is designed for high-resolution surface temperature and emissivity mapping. It focuses on capturing detailed thermal infrared imagery, which is crucial for understanding temperature variations and surface characteristics. This data is valuable for monitoring land surface temperatures, detecting thermal anomalies, and studying various environmental and climatic processes.
2. Visible - Near Infra-Red - Short Wave Infra-Red (VNIR-SWIR) Payload: Developed by ISRO, this payload includes seven spectral bands covering Visible (V), Near Infrared (NIR), and Short Wave Infrared (SWIR) regions. It aims to provide detailed surface reflectance mapping across these bands. This capability is essential for generating critical biophysical variables like vegetation health, soil moisture, and land cover classification, as well as assessing the radiation budget of the Earth.

Together, these payloads will enable comprehensive Earth observation and contribute valuable data for climate monitoring, environmental management, and natural resource assessment.
