Now we are down safely I am starting a map thread. Everything that happens during 2021 will be covered in my still-in-progress atlas, so I have to make the maps for that and everyone can follow as they evolve.
Let me know if any feature names start to show up. Preliminary map even though not much has happened yet. But if you look closely you will see something, even now. Phil -------------------- ... because the Solar System ain't gonna map itself.

I noticed that on the heli nav images at the vertical landing portion of flight 5, it is possible to draw close to radial lines through ground features, after contrast enhancement, which allow triangulation of the shadow and therefore of the landing location. As the projection from the fisheye lens appears to be centered on the image, the radial lines should appear straight on a map. I could then use my earlier map to get a handle on the position of Ingenuity after flight 5:
There is still some wiggle room but the location should be better than my earlier estimate (yellow). I will update the map. -------------------- --
