Amazing Mars image

Another amazing image from Mars Reconnaisance Orbiter has been released. This image shows layers in the polar ice cap. The layers are exposed on the side of a canyon eroded into the ice cap and show different colours due to the different amounts and types of dust incorporated into the ice layers, this image is in false colour to bring out the subtle differences. For a more realistic colour version check out Stuart's colourised version. Either way you look at it, it's a fantastic image.
