There is in fact wind. Only ~1% as much air as Earth, but it's sufficient to support phenomena like dust devils.

Of course, it's very weak, so it couldn't push over a spacecraft or building like in "The Martian", but I suspect sands shifts on a very slow timescale. I'm not sure.

I think I meant to reply to the person above you.

In the images of the post, you can see these effects of wind-driven sand and dust, such as rippled dunes.
