9. Landslides and avalanches happen on Mars.
The first images of an avalanche on Mars were taken in February of 2008. The Mars Reconnaissance Orbiter took pictures of several avalanches near the Martian North Pole. At the time, the Orbiter was looking for changes in carbon dioxide frost during spring, but they happened to stumble upon a series of four avalanches.
Researchers are still trying to determine what started the landslides. It’s also being determined if the avalanches are seasonal or happen only during spring. Scientists believe that most of the material dropped in the torrents is ice rather than dust. These avalanches are another way for NASA scientists to explore possible water sources on Mars.
