New Mars data discovered by UAH researcher

A researcher at the University of Alabama in Huntsville recently made a unique discovery about Mars, suggesting that dust storms may organize the Martian atmosphere into regions favorable for electrical activity.

The research was conducted by Chali Idosa Uga, a third-year Ph.D. student in the Department of Space Science at UAH. Uga’s research was published in The Planetary Science Journal.

What’s the significance of dust storms on Mars?

Uga found that these dust storms could increase the potential for electrostatic discharges that could impact future missions to the planet.

Uga’s work focuses on the Martian Year 34 global dust storm, a planet-encircling event that occurred on Mars in 2018, and whether such events can create conditions in which electric fields may build up to levels favorable for electrical breakdown in localized regions of the lower atmosphere. 

“Mars does not have thunderstorms in the terrestrial sense, but it does have intense dust storms in a thin carbon dioxide atmosphere. During such events, dust is lifted, transported and mixed through the lower atmosphere, creating conditions in which grain collisions can separate electric charge while the weakly conducting atmosphere may allow that charge to persist.”

What does that mean for our understanding of the atmosphere on Mars? It means future Mars missions may need to account for electrostatic environments during dust storms. During a time when scientists all over the globe are intent on gathering more information on Mars, knowing conditions in advance could save time and money.

“This result is important for surface operations because electrostatic charging can change how dust interacts with exposed mission systems.

Under intense storm conditions, charged dust may behave not only as a mechanical contaminant, but also as part of the electrical environment near the surface, influencing dust adhesion to materials, dust deposition on sensitive surfaces, instrument stability and charge accumulation.”

The study also has implications for how scientists think about Martian chemistry and habitability.

“If electrical breakdown occurs in such regions, it could alter the local reaction environment of Mars’s dusty carbon-dioxide atmosphere. That is important because the chemical state of the near-surface atmosphere influences how we interpret oxidants, perchlorate-related chemistry and the preservation of organic molecules, key issues in assessing habitability.”

Uga’s recognition at national conference

Uga’s findings were recognized at the National Science Foundation 2026 Coupling, Energetics and Dynamics of Atmospheric Regions (CEDAR) conference in Des Moines, Iowa—an event that brings together researchers studying Earth’s upper atmosphere, ionosphere, thermosphere and their interactions with space weather.

It acts as an open, grassroots forum where researchers can share new data, present ideas and collaborate on their findings.

Uga’s presentation received an Honorable Mention award.
