Since we don't have the usual landmarks on Mars that we enjoy on Earth, it can be tough to get a sense of scale for the great shots we've seen from Mars rover Curiosity. In this photo of Mount Sharp--Curiosity's scientific destination--the mound in the center of the image is about 1,000 feet across and 300 feet high. Curiosity, relative to that, looks like a speck of dirt, as you can see after the jump.
NASA also released this annotated version. Both images of Mount Sharp, taken by the rover's 100-millimeter mast camera, are part of a larger image. This cropped version is enhanced with color, which gives it a more Earth-like look, making it easier to analyze. That little black rock is about the size of Curiosity. And if you thought Curiosity was puny, you're mistaken. It's a full 10 feet long, dwarfing its sibling rovers and humans.
Needless to say, it has a lot of ground to cover.
