NASA unveils seasonal dust storm pattern on Mars Improving the ability to predict large-scale, potentially hazardous dust storms on Mars would have safety benefits for planning robotic and human missions to the planet's surface. NASA's Mars orbiters have unveiled a pattern of large regional dust storms occurring at about the same times each year, an advance that may help predict these hazardous events during future robotic and human missions to the red planet. After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the red planet's atmosphere. For six recent Martian years, temperature records from NASA Mars orbiters reveal a pattern of three types of large regional dust storms occurring in sequence at about the same times each year during the southern hemisphere spring and summer. Each Martian year lasts about two Ea
