Starting a new thread as we leave the landing site and start the drive around Seitah. It will probably be quite fast unless something interesting turns up in the ejecta of the craters along the path.
Here is a circular panorama for sol 379, already north of the landing site. Maybe there will be some drive-by shots of the landing site itself. Phil -------------------- ... because the Solar System ain't gonna map itself.

Sol 380 - the JPL map has not been updated yet but this circular view shows we have moved 200 m or more into the smooth area northeast of the last position. Easy driving here. We could see a record-setting drive next time.

Maybe! But not today. There is a sol 381 panorama but it looks identical to the sol 380 view. Perhaps a drive failed and the end of drive imaging happened anyway.

I'm beginning to anticipate that April (more or less, depending on unpredictable opportunistic science stops and/or obstacles in the path) will be this amazing sequence of gradually improving imagery of the delta outcrops, with every few days leading to an incremental but noticeable improvement, a bit like the first approach of Jupiter, Saturn, Pluto, etc. by Voyager or New Horizons. And maybe there'll be something remarkable in those images from ~150 meters away, or maybe it will just look like sedimentary layers with nothing out of the ordinary until the instruments get right onto the delta outcrops several months from now. We just don't know, but the potential is tantalizing.

Thanks, Paul. I used your image and the rest of the panorama to make my circular view for sol 383. The crater rim is obvious now.

There's a gap in the rim a few dozen metres to north, which might allow a glimpse inside.

Sorry, no look inside the crater (except possibly a drive-by). In fairness, like Spirit's view inside Bonneville, it probably wouldn't show very much.
I say 'no look' because Perseverance is now north of the crater. I haven't done a detailed analysis yet but the raw Navs show an unobstructed view of Santa Cruz plus a distant crater rim to the north, which will be Port Angeles.

Is there a reason for this pause in releasing raw images from Mars2020 that I am unaware of? The last raw image was from sol 389 and now it's sol 394. Is there some software update going on or what? I even tried to look on social media sites and there is not a single word about it.
I can still remember MER Spirit and its LOS in the first few sols on Mars, and I hope it is nothing like that this time? -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

QUOTE (tau) A piece of hardware lost or dropped during descent and landing? Nope. Too big.QUOTE (tau) A meteorite? Nope. Shape and how it seems to 'fit' against a back rock suggests in situ.QUOTE (tau) A piece of Martian rock that was hurled here from elsewhere by a meteorite impact? Eh, perhaps, but as above, based on what appears to be a 'fit' to the rock behind, it would have to be hurled, buried, then excavated.QUOTE (tau) What could that bright thing on La Orotava crater wall be? My initial guess would be a pegmatite pipe.When molten rock cools, the result is much like leaving a soda or beer in the freezer too long, aka "apple jack" (early distillers let hard cider freeze out the water, then poured out the concentrated liquor)* When molten rock chambers cool, they 'freeze out' minerals which snow down, until you're left with a magma enriched in the material with the lowest freezing point- which is usually enriched in metals, often white, and called "pegmatite". *disclaimer- don't try at home. Freeze distillation doesn't separate methanol (bad-go blind) from ethanol (good, you've made apple brandy/schnapps). To separate methanol from ethanol, you need heat distillation and condensation (e.g. a moonshine still) |

QUOTE When molten rock chambers cool, they 'freeze out' minerals which snow down, We recently got a cider press, but tis the season for: the mineral "sand" aka niter that precipitates from cooling maple syrup. (We pulled our 10 taps after getting about 120gallons of sap.) Cider is a fall thing. You can watch it snow niter, but I think you're seeing sugar on a tiny bit of unspecified "mineral." I'm not sure. |

Sol 385 Mastcam-Z What could that bright thing on La Orotava crater wall be? A piece of Martian rock that was hurled here from elsewhere by a meteorite impact? Ejecta yes, but being situated on the crater wall probably home grown. With Séítah seemingly the remnant of a lava lake or magma chamber, fractional crystallization would have resulted in layering of olivine, plagioclase feldspar etc and the impact may have breached that level. One thing about the crater. Did it impact the boundary of Séítah before the crater floor was covered by lava, embaying the crater wall or after? Given that the Séítah side seems much more eroded I would punt for after. |

Here is the sol 395 panorama in circular form. Up on top of a little ridge.
Mark, I don't have special viewing software. The images are made and viewed in Photoshop. I use these images to compare with a HiRISE image to find locations or identify features> So I just view it as a flat image and compare it with another flat image. I suppose there might be other ways to view this but I'm not clever enough to do that. Phil -------------------- ... because the Solar System ain't gonna map itself.

On the third image of Sean's post #39, the MZL_00388 panorama, there is a dark downslope flow material that looks a little like the gullies seen elsewhere. Perhaps these are much smaller, different, and just dust, but they are eye-catching. I don't think we've seen anything like this on Mars before from the ground.

Sol 395 Mastcam-Z looking east. Colors enhanced.
Port Angeles crater with layered outcrops on the inner slope. The hills in the background are probably heavily eroded remnants of delta sediments. Curvilinear layers are faintly visible on the slopes. Distance from the rover about 2.4 to 3 km. The rock on the far left behind the hillside is a small variant of Kodiak hill, distance about 3.3 km. Edit: Corrected the name of the crater |

Crater Port Angeles and Perseverance's tracks on sol 395 in stereo.
Best seen on displays with extended color space, wide gamut, AdobeRGB, or similar. Ghosting or double images in the left eye (red filter) are unavoidable on sRGB displays. The ghosting can be reduced by attenuating the green channel of the image, but then the image takes on a distracting purple tint. Edit: Corrected the name of the crater |

This SuperCam image, like details seen in the Post #39 panorama, shows the downslope flow of what might be a very fine dark dust that seems to originate from the face of the sedimentary layers. For it to overlay the usually ubiquitous brighter airborne dust would seem to indicate a substantial rate of new generation of whatever this dark stuff is. It, again, is reminiscent of what on much larger scales is seen in gullies which raises, again, the question of whether dark downslope flow is purely dust, or is there some H2O involved? Otherwise, it seems like some of the darker rock is eroding at a considerable rate in the present time. Otherwise, how could these dark trails not be covered with the baseline of brighter martian dust?

Was the first one a safe mode? I hadn't heard anything about it. That would certainly be a reasonable explanation. I believe Steve Ruff mentioned that in his most recent episode on Youtube. https://www.youtube.com/c/MarsGuy Most people aren't authorized to discuss mission ops publicly because of project rules. In general, I think there would be a press release about a major outage or problem, but a minor one might well go unmentioned. -------------------- Disclaimer: This post is based on public information only.

Thank you for the image, Tau. This particular image got my inner sedimentologist very excited, I'm sure it'll be the subject of several publications. I made a quick annotated version showing my preliminary interpretations. Essentially I interpret this conglomerate deposit as a high energy flash flood deposit during an interval when lake levels lowered. The sheer size of the clasts transported (the largest is ~1m across, based on an LPSC abstract which studied lower res images of this same outcrop) requires a powerful flood to transport them, and the high degree of rounding of the clasts suggests they were transported quite some distance. Given that the clasts appear to be several different colours and so lithologies, this agrees with the long distance idea. I suspect they were sourced from outside the crater, and so potentially have travelled many km, and could represent basement materials. The deposit itself is not sheet-like and continuous but instead appears channelised and pinches out, so perhaps the flood followed a pre-existing (dried up?) river channel. The return of delta sandstones above it might indicate a rise in lake level. There are curious discontinuous patches of bright angular 'bits' embedded with this sandstone & I'm not sure what they are, marked in pink. The presence of eroded-out rounded boulders stratigraphically higher, towards the delta top, indicates there was at least one other flash flood deposit later on, so this was not an isolated event. Hopefully there are conglomerate deposits where the rover will be traversing when it climbs up and onto the delta in a few weeks. Because if I'm right, and these rounded clasts represent distant lithologies from the Jezero watershed, then they could be ancient (Noachian) basement rocks which would be a very high priority for sample return. |

Another drive or two and the backshell should be visible to the south These drives, particularly the most recent one, are a total flex for the Perseverance team. I think its safe to assume, given the length of the traverses, that most of the drive is managed onboard the rover. That Sol 397-8 traverse is magnificent. They must be walking on air right now. It is a treat to watch. |

I would say it made a sharp turn to avoid the trio of large rocks along the edge of the trough and stopped soon after that. The shallow trough itself is not much of a hazard in my opinion.

Thanks a lot Thomas for this nice picture
I hope that the view will improve over the next days and that we will gather pics that will be as nice as the ones taken from the Zhurong Chinese rover (taken with the MastCam-zoom if we are not nearing it as close as the Chinese did to their parachute) and thus, enable NASA/JPL to make a spectacular Press release (as the Chinese did also). Here is its version in 3D. Enjoy |

Thanks Tau for the colourful panorama. I've located the different scarps visible in that image. There are two conglomerate outcrops visible, one much more extensive and coarser grained than the other, although they might be lateral equivalents of the same conglomerate bed. The 'three forks' area the rover will be driving up is still out of view, once we swing round that subdued scarp at the far left of the panorama it'll be in view for the first time. At the current driving rate, we could be there by this time next week!

Sol 405 she turned around!! Looks like she might approach the base of the delta Really great, but... Sorry to say that "ordinary" people here tell us that those Mars rocks always look the same and they feel quite bored. This is a real concern not to be avoided. =>> We need to give them inspiring pictures : today, they feel more concerned by the emergencies of war and the constraints of daily life And we have not to forget that they are also taxpayers (even in France for experiments paid on the Perseverance rover). Before going to the base of the delta, we are many people involved in fostering space exploration (not only at TPS but also in space-related organizations in France) thinking that it should be nice to take the opportunity of being close to the parachute and its backshell (a mere 2-day driving away) to go there first and take some quick & spectacular pictures of them |

I would avoid driving near the parachute.
We learned not long ago that even in the thin Martian atmosphere, a sudden dust storm can throw sand onto the rover deck. Movement of the parachute during a storm or by a dust devil is quite possible. I would not want the rover to get tangled in a parachute. Better, the rover avoids unnecessary risks and provides spectacular images of Martian landscapes and rocks. |

Sol 405 she turned around!! Looks like she might approach the base of the delta If they do indeed decide to drive towards the base of the delta, then checking out the geological contact between the lake sediments and the Maaz formation (lava flow) might be the reason why. Perhaps they think they've spotted an outcrop that shows this, or they think they'll be able to see the contact using RIMFAX (the ground-penetrating radar). Investigating this contact would be important because hopefully they'd be determine whether the lava flow postdates the lake or pre-dates the lake, which means when we do radiometric dating on those igneous rock cores upon return to Earth we'll know whether we're getting a minimum or maximum age for the delta. Alternatively, perhaps they just decided to turn on the spot for some reason. Guess we'll see soon. |

Better, the rover avoids unnecessary risks and provides spectacular images of Martian landscapes and rocks. I was not speaking of rolling on Perseverance's parachute, but get close enough to make a nice picture, like the Chinese did. And the local scenery with its background mountains, would make such pictures truly spectacular Spectacular enough to make world press publications (nobody noticed the Chinese picture release, save from space enthusiasts). |

Spectacular enough to make world press publications (nobody noticed the Chinese picture release, save from space enthusiasts). Nobody would notice Perseverance doing it either, apart from space enthusiasts. Tianwen-1 was blessed with a very traversable terrain and a strategic route that went straight past their backshell anyway. It essentially cost them nothing to do it. M2020’s backshell is not so fortunate. It landed in some rough terrain - round trip to get from here to the far side of it, safely, and back again, is probably two weeks of effort. That doesn’t seem a sensible thing to do with ~$30M worth of prime mission. It would likely gain as much “Why are we littering Mars” coverage as “Wow -let’s pay for more space” coverage. I have already seen the ‘littering’ comment repeatedly after the few Mastcam shots. This mission, like Curiosity, has shown it is totally open to doing cool stuff purely for EPO (selfies, etc) but an expedition to go get a back shell postcard I think would constitute a pretty irresponsible way to spend prime mission time. |
