Midnight Planets has reported Curiosity's movement of ~46.3m WSW (-116º) on Sol 1353.
Only 7 L-NavCams were available for this rough & ready stitch in MS ICE, the raws are a little overexposed, but they may assist in pinpointing the location. I cropped the stitch a little to get it under the upload limit. I'll post the full resolution 360 on an image host as the images become available, unless someone beats me to it |

So this pretty much tells us mars atmosphere eats and corrodes stuff over a period of time. Much more than earth... That explains the wasteland of hollow rocks.

Sorry, I should have been clearer - Curiosity has tan lines. Instead of spring breakers writing-on-somebody-with-sun-tan-lotion, it's engineers, sticker residue and aluminum that was re-anodized on earth. Same end result, you can see the pattern where something protected the surface. The part that seems poetic is that the covers had to be re-anodized because the anodizing flaked off, creating a mud crack pattern, likely due to temperature variation. That same temperature crack pattern seems to appear on the exposed rocks around curiosity. |

To be clear, I don't think there was ever adhesive of any kind. I think the original white pattern was some kind of paint/marking ink (probably epoxy-based, that's what we use for labeling) that was stripped off when the cover was re-anodized. -------------------- Disclaimer: This post is based on public information only.

Thanks for solving this puzzle I have one remaining question. The reworked cover contains a single white line in place of the fiducial marker on the anodised cover, does that line perform a similar role to the earlier markers? Or does it have a different role? |

I don't see what you're talking about. As far as I know all of these targets were used for arm checkout and don't have any ongoing operational role, but I could be mistaken. -------------------- Disclaimer: This post is based on public information only.

Eh, pretty sure it is the a white line across the lower portion of the "ping-pong-paddle". Hmm, seems like the "handle" is a bit darker than the "face" |
