NASA's MESSENGER mission has just sent back it's first photos from Mercury. This side of the planet has never been seen before, since Mercury's spin is locked to its orbit around the Sun (in a rather unusual way).Nonetheless, I really do wish NASA would bother to provide scale bars on their images. Scale bars transform beautiful photography into scientific images.

You can clearly see the curvature of Mercury; scale bars are left as an exercise for the reader.
