BENGALURU, October 17 — The Indian Space Research Organisation (ISRO) and the European Space Agency (ESA) signed a comprehensive bilateral scientific cooperation accord on Saturday to operationalize joint space weather forecasting and solar wind modeling.
Under the collaborative framework, real-time observational data from India's Aditya-L1 solar observatory—stationed at the Sun-Earth Lagrange Point 1 (L1)—will be integrated with ESA’s Vigil deep-space mission and European ground-tracking antenna networks. The combined telemetry will enable continuous tracking of Coronal Mass Ejections (CMEs), high-speed solar wind streams, and intense solar flares that generate disruptive geomagnetic storms across Earth's magnetosphere.
ISRO emphasized that cross-calibrating in-situ plasma analyzers and magnetometers will dramatically enhance predictive lead-times for satellite operators, protecting low-Earth-orbit communication constellations, civil aviation communications, and terrestrial high-voltage electrical transmission grids against solar particle events.
The scientific objectives and instrumentation payload of the Aditya-L1 mission (launched September 2, 2023 via PSLV-C57 to Halo orbit at L1), orbital physics of celestial Lagrange points (L1 to L5), the organizational history of ESA (founded 1975), and space weather hazards represent critical themes across UPSC GS-III (Science & Technology).
