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

[Bill Harris]

The "top airfall coating" is most likely orange-brown dust, and it appears featureless white or very bright in my images due to clipped highlights in the Mastcam-Z raw images that I used.

That makes sense. You're trying to show the maximum range down to shadowed areas, and some other areas need to fall by the wayside.

Attached is the thumbnail of this 18 Mb 13367x2026 panorama which seems to deserve to look at.



Unfortunately no other info is provided at its original location at one of image hosts - no (nick)name, no sol number, no camera name.

This is a Sol 96 MastcamZ panorama. Here's my version of this panorama that I stitched last year :



And the corresponding Postcard if you want

Thank you, Ant103!
Am I right, that La Orotava crater is flatly seen beneath the scarps in the left part of your postcard and in the center of 'unknown panorama'?

This is Hahóóts'aa'



By the way: I have seen two different spellings of the crater in Navajo: Hahóóts'aa' (with a glottal stop at the end) and Hahóóts'aa (without).
Does anyone know which variant is correct?

[tau]

In the panorama of the previous post, only the northern part of Hahóóts'aa' crater is visible.
Here is a sol 96 Mastcam-Z panorama showing the entire far rim. Numbers are distances from the rover's sol 96 position.
We can clearly see the inner slope of the northern and western rim of Hahóóts'aa' (distance 1060 to 1200 m in the image).
However, the dunes and large rocks that at first glance look like the near rim are the slightly elevated edge of the terrain around Séítah (distance 220 to 250 m).
The green line is the visible part of the planned traverse of Perseverance to the delta.

The short distance (370 m) covered in Flight #21 increased my concerns about the following.
Shall the helicopter manage to reach the zone from where it shall be able to hear from rover again from the opposite 'shore' of Seitah? By 'again' I mean the moment after the rover shall re-appear from behind of western rim of Hahóótsaa. Yesterday the last sample was cored, and very soon Perseverance shall run to La Orotava thus leaving the zone of radio availability from Ingenuity...

To your opinion the helicopter shall be aimed to the eastern (here - bottom) rim of Hahóóts’aa rather the western (here - top) one? Or these are only the lines showing scarps A and B?

[tau]

These are two lines of sight, connecting the rover's position on sol 96 with cliff A and slope B, crossing Hahóóts'aa' crater.
I inserted the lines to show which crater we see on Damia's postcard.
The lines have nothing to do with the helicopter.

I see, I misinterpreted them. Meanwhile the first NAV photos from flight #21 appeared



while "m20_heli_waypoints.json" still ends with flight #20.

The JSON for Flight 21 is now available

Lori Glaze presented this slide detailing the samples collected and the abrasions to date by Perseverance. From this past week's Space Week presentations. Sorry, the screen capture is larger than this system will upload and I don't have time right now to fuss with the file size.

Her presentation only had two slides with information; the other one showed current and planned planetary missions. Presentation

Let me try to help with it

Moderators: maybe both posts shall find a better placement in the special topic that is already created for this stuff?

Cherurbino, thanks. And I'd forgotten about that thread I created.

Placed your version of the image there.

My take on the full sky panorama taken with Navcam Left on sol 321 at 15:17 LMST. A beautiful light!
