It's always a treat to be reminded that we have spacecraft orbiting Mars right now, and a new image from one of these Red Planet probes does just that.
The European Space Agency's (ESA) Mars Express has beamed to Earth a beautiful view of a region on Mars known as Mamers Valles. This is a sweeping valley system that stretches across nearly 600 miles (1,000 kilometers) of land. And if your day is feeling a little dry, there's a little game you can play while looking at the image.
