So imagine that you're a Mars rover, right? You're just curiously wandering around Mars, collecting whatever you find, analyzing dust and stuff (wanted to say dust and shit, but then I realized that the vast consequences of finding an actual shit on Mars, so yeah, stuff it is). And suddenly you see (detect/record/whatever) this:
I mean, looks quite boring, right? A bit like some kind of children's firework going on.
Would it be more interesting if I told you that thingy is 200-400 meters tall?
Also, that 'thingy' is called a dust devil - it's basically vortex of wind that's sucking in the dust around. We even have them on Earth but most of the time they're not bigger than 1 meter and they disappear pretty fast, which makes their name the most interesting thing about them.
Not on Mars though. There they can easily get 20 km high and they seem to be far more frequent than on out blue planet. Well at least judging from this photo, considering that the lines are trails of dust devils.
RIGHT?!
So HERE...
And one where the devils went through a crater. I personally think it's marvelous...
One that's more colourful...
And a final one!
