Finishing work in and around Seitah, sols 238-378 Options

Sol 328 SuperCam Remote Micro-Imager of delta cliffs with a "marsonaut" for scale and a sol 308 Mastcam-Z context.
The images were aligned horizontally.
The layered outcrops to the right on the talus have a dip angle of at least 20° or more, depending on how they are cut at the surface.

Sol 331 SuperCam Remote Micro-Imager of layered delta (or river) sediment outcrops with two "marsonauts" for scale and a sol 308 Mastcam-Z context.
The images were aligned horizontally.
The distant marsonaut stands at a small crater on the inner wall of the Jezero crater.

Sol 333, a small drive up onto the ledge, now facing the sampled block for another attempt.

A compilation of SuperCam RMI images of the delta cliffs from sol 306 to sol 331 in a Mastcam-Z context panorama and a HiRISE map.
Areas not visible from the rover position are grayed out in the HiRISE map. The contour interval is 2 m.

Tau, your work is amazing and very useful.

Sol 335, moving to get a better position for sampling.

Thank you, Phil, for your motivating and encouraging words.

On sol 337, the third coring attempt on the same rock appears to have been successfully completed:

Looks like a long drive on sol 340
4-tile NavCam looking back after the drive
The low sun caused a few exposure issues, but I still like the resulting mosaic (roughly assembled in MS-ICE)

The third drill hole seen by Mastcam-Z on sol 339
1. Left eye f = 110 mm filter 0 (RGB) raw image
2. Left eye filters 1 to 6 principal components false colors
3. Right eye filters 1 to 6 (infrared) principal components false colors
Interestingly, the drill tailings of the hole drilled on sol 306 have changed their multispectral color (dust from the dust storm?, aging of fresh surfaces?)
4. f = 34 mm anaglyph with discarded pieces of the second core
1 . . . 2 . . 3 . . 4

Sol 340, the long drive Paul mentioned brings us to this spot. This could be the longest drive of the mission so far but I won't speculate about the exact length.

This panorama was very tricky. I don't really have time to do this but it's addictive.

JSON and GeoJSON are now reporting the length as 237.78 meters, so looks like a Mars rover record.
What is the longest drive on the Moon? Is it a solar system record?

Glad you still find time to do those circular pans, all I can do is the 5 individual NavCam 4-tile mosaics, the 360 pan is way beyond my skillset...

The longest drive on the Moon is tricky because the situations are in no way comparable. Strictly speaking I suppose the longest single uninterrupted drive was from the Apollo 17 lunar module to Station 2 at South Massif on EVA 2, driven by a human (Gene Cernan). For a robotic rover it was 3000 m (approx) during a single work shift for Lunokhod 2, driven using a live TV signal (slow scan but still live). Mars rover drives are all pre-programmed, though Perseverance is making use of advanced autonavigation software which must have been used here. The longest drive in a single sol on Mars before this was 220 m on sol 410 of Opportunity's mission. So this is a new record for Mars.

Interesting that the tracks have a "reflective glint" to them. This impresses me as unusual for Mars. I've seen this on the Moon where the Buggy or Rover compresses the Fairy Castle Structure of the regolith.

I'm looking looking forward to seeing a map position and also getting a LOS connection with Ingenuity again.
