Explanation: Winds on Marscan’t actually blow spacecraft over.But in the low gravity, martian winds can loft fine dustparticles in planet-wide storms,like the dust storm nowraging on theRed Planet.From the martian surface on sol 2082 (June 15),thisself-portrait from the Curiosity rover shows the effects ofthe dust storm,reducing sunlight and visibility at the rover’s location in Gale crater.Made with the Mars Hand Lens Imager, its mechanical arm is edited outof the mosaicked images.Curiosity’s recent drill siteDuluthcan be seen on the rockjust in front of the rover on the left.The east-northeast Gale crater rim fading into the background is about30 kilometers away.Curiosity is powered by a radioisotope thermoelectricgenerator andis expected to be unaffected by the increase in dust at Gale crater.On the other side of Mars,the solar-powered Opportunity roverhas ceased its operations due to the even more severe lack of sunlightat its location on the west rim of Endeavour crater.
