Looks like some kind of mining operation, with a central power station, might look like sand but who is to say? are these for sure pictures from mars,
and not the Sahara desert or another place here on earth?
If they are from Mars, then I would say that something is certainly going on there, way too big to be a probe shield, they look like huge land rapers,
you know the giant machines used for mining coal on the surface.
