MAVEN Data Reveals First Zwan-Wolf Effect in Mars Atmosphere During 2023 Solar Storm

December 2023 MAVEN observations gave researchers the first evidence that the Zwan-Wolf effect occurred inside Mars’ atmosphere, not just above a planet in a magnetosphere.
A coronal mass ejection made the signal visible by battering Mars with solar-wind plasma, amplifying what Christopher Fowler said is usually too weak for instruments to detect.
The finding suggests solar wind can be redirected around worlds without strong magnetic fields, extending a phenomenon previously associated with magnetized planets such as Earth.
MAVEN saw signatures down to the lowest altitudes it sampled, raising new questions about how deeply space-weather effects penetrate Mars and what that means for future robotic and human missions.
With MAVEN now lost, how will we study Mars's unexpected atmospheric shield to protect future astronauts?
Is Mars's newfound 'hidden shield' a true planetary defense or just a fleeting response to violent solar storms?
A lost probe's data revealed Mars's secret shield. What other cosmic secrets are hidden in old mission archives?
The Zwan-Wolf Effect on Mars: MAVEN’s Last Breakthrough and the Future of Atmospheric Research on Unmagnetized Worlds
Overview
As of May 2026, NASA lost contact with the MAVEN spacecraft, and despite renewed efforts using assets like the Green Bank Observatory and the Curiosity rover, no sign of MAVEN has been found. This ongoing uncertainty and difficulty in re-establishing communication have raised serious concerns about the probable loss of MAVEN. The situation is grave because MAVEN was essential for studying how Mars lost its atmosphere and water, providing invaluable data on atmospheric escape. If recovered, MAVEN could have continued its mission for at least four more years, making its potential loss a significant setback for Martian atmospheric research.
