NASA shares eight stunning images from the surface of the Red Planet

These 26 holes represent each of the rock samples NASA's Curiosity Mars rover has collected as of early July 2020. A map in the upper left shows where the holes were drilled along the rover's route, along with where it scooped six samples of soil Two sizes of ripples are evident in this December 13, 2015, view of a top of a Martian sand dune, from NASA's Curiosity Mars rover Here you can see clouds in the Martian sky captured by NASA's Curiosity rover. Mount Sharp is one of the images shared by NASA to mark the anniversary of Curiosity landing on Mars - the image is actually 44 pictures stitched together. Curiosity will never venture to the upper portion of the mountain; instead, it's exploring the many layers found lower down. Each has a different story to tell about how Mars, which was once more like Earth (warmer and wetter), changed over time and will reach the next layer in 2021.
