Mars’ global dust storm size visualized in new animation

A new animation helps us visualize just how massive the Mars dust storm is. This storm, which obscured the Sun and resulted in NASA’s Opportunity rover going into a deep sleep, at one point was “only” as big as North America. In the weeks following that detail, NASA continued to update the public on this storm’s size, using countries as a reference. A new image, though, shows us exactly how much of the Red Planet is covered by this storm.
