Evidence to show that beings or being is cleaning off the solar PV Panels etc. of the Curiosity Rover! Just can't be wind in my opinion! Please listen to a former Nasa employee about two minuets in the video. Even if there was wind, there would also be returned dust and in the nooks and cranny's of the solar panels you would see at least some remains of dust!
I enjoy finding out new things about mars. Especially photos that tell stories! Which so many seem related to mars loosing it's atmosphere in extreme ancient times!
