Mars shows Earthlike solar-wind bending in its atmosphere

NASA’s MAVEN data, gathered after it went quiet in 2025, reveal the Zwan-Wolf effect—an Earth-style solar-wind deflection—occurring in Mars’ upper atmosphere during a December 2023 solar storm. The finding suggests Mars’ atmosphere can host temporary magnetic structures that funnel charged particles, implying the effect may operate continuously there but is usually too weak to detect; the results were published in Nature Communications. NASA also notes MAVEN’s ongoing recovery efforts after a period of contact loss.

Mars Atmosphere Reveals Earth-like Zwan-Wolf Effect Under Solar Storms

NASA’s MAVEN mission has for the first time observed the Zwan-Wolf effect—an Earth-originated phenomenon where charged particles are squeezed along magnetic flux tubes—in Mars’ ionosphere during a large solar storm, a finding published in Nature Communications that suggests space weather can influence the Red Planet’s upper atmosphere and may operate at low levels even without a global magnetic field, with implications for atmospheric loss and insights for other unmagnetized worlds like Venus.
