[Photo Group] Why There Is No Dust Removal System on the Mars Rover

According to the latest report of Britain's New Scientist magazine, perhaps many people have already heard about the recent big dust storm on Mars that covered the solar panels of Mars Rover "Spirit" with a layer of dust. Now this Mars Rover is reluctant to give up and is struggling hard against death. Although all its instruments are turned off, the "Spirit" still needs some energy to heat electronic equipment during cold nights. If it cannot charge the battery sufficiently during daytime, it will be frozen to death at night. The death of the "Mars Pathfinder" was caused exactly by a battery that was not charged.
