Scale needed with Mars images

Question: When you publish images from Mars, would it be possible to have some sort of scale published with the images so we can obtain an idea as to how large an area is being covered? -- Reg Morgan, Coulee Dam

Answer: Your suggestion on providing scale for the Mars images is a good one. I'll share it with our editors and we'll try to provide some kind of comparative information the next time we have some new photos from Mars. -- Gary Graham, managing editor
