ESA orbiters record record‑breaking solar superstorm striking Mars and altering its atmosphere

ESA's Mars orbiters logged a rare solar superstorm that struck Mars — producing the largest atmospheric response observed there to date — and confirmed the same event also impacted Earth. Instruments recorded changes in the Red Planet's upper atmosphere, yielding new data on storm interactions with non‑magnetized planets.

What Hype is tracking

  • ESA’s measurements document the biggest atmospheric response to a solar storm ever seen at Mars, providing direct observational data to refine models of space‑weather effects on non‑magnetized planets.
  • The event also affected Earth, reinforcing links between major solar eruptions and cross‑planetary impacts on satellites, GNSS and communications; see recent Earth‑striking activity such as the Jan. 19 X1.9 flare and its S4/G4 impacts.
  • These observations underscore the operational value of improved early‑warning systems for extreme solar events and connect to work on a validated forecasting system intended to give earlier notice of major storms.
