Take a look at HiRISE's birds-eye view of MSL Curiosity, taken on the 157th sol of it's mission in Gale Crater. In this image you can see the rover itself, as well as tracks left from MSL's movement across the Martian terrain (this is especially true if you click on the image). The bright white/blue dots on the right shows the the area that was directly below MSL's Sky Crane rockets. Because of wind and other factors, the earliest tracks from MSL have begun to fade, but fortunately they can still be made out in the larger high resolution version (just click the image below to see it)!
This image is quite significant because it is the first color image showing MSL's tracks from orbit. It is oftentimes these images that provide us perspective because they show us the impact we are having on this pristine planet. Every rover we send to Mars is breaking new ground, every image shows a never before seen world, every soil analysis enhances our understanding of the solar system and provides context for our place in the universe.
