looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren't created by Martian bees or spiders; they are actually formed from an ongoing process of seasonal change from created from water ice and carbon dioxide.The HiRISE camera on the Mars Reconnaissance Orbiter has seen a lot of polygon shapes in the years since 2006 when it went into orbit of Mars.
