Image sources

A surface texture is a claim about how a body looks. The same rule applies as to a number: without a verified licence it is not used and the body is drawn instead. Lighting, terminator and atmospheric limb are always computed, even over a photograph.

Image provenance for each body

The licence “cited” means only the value was taken from that source, that is the number and its uncertainty, not the text or the image. Where the author is a US federal agency, the work is free by law. ESA and ESO have their own terms requiring attribution. Nothing beyond that is claimed: inventing a licence would be worse than leaving it out.
