“Dust Devil” On Mars
We can thank the infamous Curiosity Rover on Mars for this one. We’ve found that Mars has a lot of things in common with Earth, especially its rocky surface. It also experiences some similar weather or elemental phenomena that we see on Earth. Dust Devils are the perfect example of this. We’ve seen them on Earth several times and like tornadoes, they are caused by the forced impact of hot and cold temperatures. The surface area of Mars is relatively warm, so when cool air is present, dust devils can occur. Essentially, colder air is at the center of the dust devil vortex and it is protected by an outer wall of hot air, causing it to spin around. While it might not always be as destructive as a tornado, dust devils can be quite dangerous. Thankfully, our rover friend was fine. NASA has since studied these more.
