Thanks for the feedback! Yes, it is hard to get right. That's why neither NASA nor Google have a great blend.

The artifacts should be mostly gone with our next version which we are rendering in the next few days.

Greyish areas come from areas where Viking imagery is mostly black. We also updated this part in the next model. Thouhg, that's a tough one.

Let's see how you like the next version!

Are you also adjusting the overall color? Your images have now strong pinkish cast instead of the more natural orangeish tones.

For parts where viking data is not usable, maybe filling in the color information based upon surrounding area would make at least prettier end result.

Yes, those are two really good points. What we do is first we have to find a middle ground on color, contrast, brightness between all Viking photographs. Because there are differences between each. Then we make a decision of what an average color looks like.

Filling in an average color for the overexposed areas is what we'll do for version 1.0 coming in a few days. Running locally it does already look quite nice. Hope it will turn out well on the web app!
