Mars Orbiter has captured thousands of images in high resolution from the surface of the Grumpy Reddish Planet. The picture you see here is a chain of pit craters. That must have been one helluva noisy event. Reminds me of the walls at the Entebe Airport.
Anyway, the High Resolution Imaging Science Experiment (HiRISE) camera takes pictures that are about 6 km wide and some greater amount long, wiht resolution down to as small as one meter. The pictures are being released a few at a time and you can access them here.
