The dipping structure in the Rimfax trace seems to disappear at the third position Tau and it would be interesting to see subsequent results to determine if similar structure re-appears. The trace presentation seems to be truncated in the X axis which accentuates the angle of dip which if the trace were extended to agree with the 15 metre depth would be around 7 degrees.

The Rimfax diagram has two small marks for sol 201 and sol 202.
In the Hirise map, the positions of sol 201 and sol 202 can be connected by a stright line ("as the crow flies") with a linear distance of about 43 m. This line is almost perpendicular to Artuby ridge. The ridge can be assumed to represent a strike line of the layers. When the Rimfax diagram between sol 201 and sol 202 is stretched horizontally according to the vertical scale, we get a dip angle of about 11° to 12°. |

Yes, a move, but really just a turn in place (possibly involving a drive downslope, a turn and back upslope, but I only see the end result).

Roughly processed sol 248 end-of-drive 4 tile Navcam. The site index incremented which could indicate we are at, or very close to the next sample site. Plenty of interesting contacts here. Especially that (apparently) loose rock at the top with the dark basaltic (?) unit on top of the grey clastic (?) unit on top of the in-place units. --Bill -------------------- |

That's a beautiful image of Kodiak. Thanks!
Here is a circular panorama for the current position. Phil -------------------- ... because the Solar System ain't gonna map itself.

Paul: "The site index incremented which could indicate we are at, or very close to the next sample site."
I was asked about site numbering, and i don't have specific information about Persererance, but this is a document for Curiosity which discusses sites. MSL_Coordinate_Frames_Mar5_2013.pdf ( 343.63K ) Number of downloads: 422 I expect the situation is the same for Perseverance. A new site number doesn't really suggest sampling is about to happen, though I expect it is. Phil -------------------- ... because the Solar System ain't gonna map itself.

The site incrementing is usually because the propagated error in attitude knowledge has reached a certain limit. It's usually based on cumulative IMU on time.
