This composite image from Aug. 9, 2018 photos made available by NASA shows the Curiosity rover at Vera Rubin Ridge on Mars. A thin layer of dust is visible on the nuclear-powered rover, the result of a storm that enveloped the planet this summer. The darkish sky is from dust still in the atmosphere.
