New research has indicated a strong link between hot, sunny days and the occurrence of dust storms on Mars, with about 78 percent of the storms caused by increased solar heating, according to a study presented at the annual meeting of the American Geophysical Union in Washington. Come before. The DC study, led by Heshani Pieris and Paul Hayne of the University of Colorado, Boulder, analyzed data from NASA’s Mars Reconnaissance Orbiter, revealing patterns that may help predict these atmospheric events.
Insight into dust storm patterns
The researchers examined eight Martian years – about 15 Earth years – of data collected by the Mars Climate Sounder instrument. Observations focused on two types of dust storms, classified as “A” and “C” storms, which originate primarily in the planet’s northern hemisphere and pass through Acidalia Planitia and Utopia Planitia. . The study found a direct link between prolonged surface warming and the emergence of these storms.
In a statement, Pieris highlighted the significant impact of dust storms on Mars missions, noting their tendency to cover solar panels with fine particles, which can disrupt operations. This was exemplified by NASA’s Opportunity rover, which became inoperable during a global dust storm.
Dust storm forecast likely
Pieris and Hayne’s research suggests the possibility of predicting dust storms on Mars based on surface heating patterns. An algorithm developed during the study showed a 64% confidence level in predicting “A” and “C” storms, offering a potential tool for managing the risks posed to future crewed missions.
According to the report, although the study marks progress, Hayne pointed out that fundamental questions about dust storm formation remain unanswered, including the factors that allow local storms to develop into global events. Data from NASA’s inactive Mars Global Surveyor support the findings, showing that imbalances in solar energy absorption during warm periods could boost storm activity.
