Curiosity at the Vera Rubin Ridge (IMAGE) University of Maryland Caption In this photo, NASA’s Curiosity rover pauses for a “selfie” on Vera Rubin Ridge, on the lower slopes of Mount Sharp—the peak of which can be seen directly behind Curiosity’s mast. The rim of Gale Crater can be seen in the distance, on the left horizon in the image. Researchers have used data from Curiosity’s navigational sensors to suggest a new explanation for the formation of Gale Crater and Mount Sharp.
