We have complete trust in our Indian partners: French National Space Agency

The TRISHNA mission is a significant Earth observation satellite designed to monitor surface temperature, emissivity, and radiation variables at a high spatial and temporal resolution. This data is critical for surface energy budgeting and understanding the impact of climate change on water and food security. The mission utilizes two primary payloads: a Thermal Infra-Red (TIR) payload developed by CNES and a Visible - Near Infra-Red - Short Wave Infra-Red (VNIR-SWIR) payload developed by ISRO. The recent failures of the PSLV, specifically in the third stage, highlight the inherent risks in space exploration. The third stage of the PSLV is crucial for inserting the payload into its intended orbit. However, ISRO's strong track record and the robust design of the PSLV remain key factors in international partnerships. For UPSC, understanding the specific applications of remote sensing satellites like TRISHNA (e.g., evapotranspiration monitoring for water management) and the technical components of launch vehicles like the PSLV is essential.

The Indo-French space collaboration is a cornerstone of the broader strategic partnership between the two nations. This partnership, which dates back decades, is characterized by mutual trust and shared objectives in space exploration and technology development. The reaffirmation of trust by CNES despite recent setbacks with the PSLV underscores the depth and maturity of this bilateral relationship. This cooperation extends beyond mere technical exchange; it represents a strategic alignment in addressing global challenges like climate change and resource management through shared space capabilities. For UPSC, analyzing the nuances of bilateral space agreements, the strategic implications of technology sharing, and the role of space diplomacy in strengthening international ties is crucial.

The TRISHNA mission directly addresses pressing environmental challenges, particularly those exacerbated by human-induced climate change. By providing high-resolution data on surface temperature and radiation, the satellite will significantly enhance our ability to monitor evapotranspiration—the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants. This monitoring is vital for efficient water resource management, especially in regions facing water scarcity. Furthermore, the data from TRISHNA will contribute to more accurate surface energy budgeting, aiding in the assessment of climate impacts on agriculture and food security. For UPSC, connecting space technology applications to environmental monitoring, sustainable resource management, and climate change adaptation strategies is a key analytical skill.
