Several times the amount of dust on the solar arrays have reached a critical level; that has been determined to be too great for the continued operation of the rover. The mars rovers have been taken offline due to insufficient energy levels. A women in a you tube video who actually worked for NASA describes seeing humans walking on mars on the central control monitor. Could these cleanings be connected? Check it out.
