Space weather poses underappreciated risks to modern technological infrastructure. Analyse the threats and evaluate India's preparedness in light of Aditya-L1's observations.

Space weather refers to disturbances in the near-Earth environment caused by solar eruptions such as Coronal Mass Ejections (CMEs). ISRO's Aditya-L1, India's first dedicated solar observatory placed in a halo orbit around Lagrange Point 1, about 1.5 million km from Earth [1], has shown that these risks are real and immediate rather than remote.

Decomposing the threat

• Space assets: During the October 2024 storm, the CME's turbulent sheath compressed Earth's magnetic shield so severely that geostationary satellites were briefly exposed to harsh space plasma [2] — endangering communication and navigation constellations like NavIC and GSAT.
• Ground infrastructure: Auroral currents super-intensified, a process that induces damaging currents in long power lines and pipelines [2].
• Navigation and aviation: Auroral currents extended abnormally equatorward in the dawn sector during the May and October 2024 storms, disturbing satellite, navigation and power transmission systems [3].
• Atmospheric drag: Storm-time heating of the upper atmosphere accelerates atmospheric escape [2], increasing drag and orbital decay for low-Earth-orbit satellites.

Evaluating India's preparedness — strengths

• Upstream sentinel: ASPEX's in situ solar wind measurements confirmed that sudden pressure changes drove the disturbances [3], giving India independent early-warning capability instead of dependence on foreign data.
• Scientific maturity: SUIT's imaging of a solar flare "kernel" [4] and the Astrophysical Journal study on the October 2024 event [2] establish India as a data-contributing nation in global space weather research.

Gaps

• Science has not yet been institutionalised into operational forecasting; India lacks a dedicated national space weather prediction centre with real-time public alerts.
• Weak coordination between ISRO, power grid operators and telecom regulators leaves warnings unactionable, and space weather remains outside mainstream disaster management planning.

Aditya-L1 has converted space weather from a theoretical concern into an evidence-backed infrastructure risk. The logical next step is an institutional bridge — a national space weather cell issuing graded alerts to grid, aviation and telecom operators, with space weather recognised as a notified hazard. Sustained investment in solar observation will thus secure the digital backbone of a Viksit Bharat.
