figuring this "Perseverance Valley" thread should populate with said content...are we there yet??
Here are some stereo views from sol4786 images of presumably water-carved topography downslope of the spillway (ICE didn't deal well with the contrast scope so at left is anaglyph of 3 pairs, crosseye of left portion, crosseye of right portion, at right is a parellel of most lumpy section). |

The pancam images for the past several days show a ground texture that looks like it is cemented together and really interesting textures. Maybe some of the image wizards can put these images together for all to see. We won't be getting too much back for a while, but channel already looks very interesting.

nice to see MI images being taken again sol4787, these look set up to stitch for stereo pairs so heres the stitch and one of its sub-pairs in crosseye/anaglyph

I'm not so sure about the terrain being cemented. The RHAZ show quite visible cleat marks indicating the soil can be compressed by the cleats. To my untrained eye, this looks more like gravel. Anyway, parking brake is set, we even turned the RF wheel a bit to keep things according to MDOT (Martian Department of Transportation) regulations. See yoou in a couple of weeks.

OK Maybe not cemented, but some of these slabs look polished--almost like glacial polish. Does this look like polish by running water to any of you? -------------------- |

Hi floyd,
we have seen what a couple of million years of low density Mar's wind can do to 'fluted' rocks. I think the environment there is alien enough that we cant quite appreciate the processes On Earth you be hard pressed to find a dozen 'craters' due to fast (compared to mars) erosion (rain, winds, quakes, tectonics, oceans) These could be stream cobbles or wind eroded ... I am waiting on Grotzinger .et al to weigh in. But it sure is fascinating! Awesome image! See you around town, fellow Bostonian! -------------------- CLA CLL

Perseverance Valley indeed seems to differ somewhat significantly in the bedrock and consistency of the soils, comparing relatively similar filter#2 views from Marathon sol4122 with its more pillowy bedrock and angular shards versus the more pebbly and sheared surface seen here in Perseverance sol4791.
That observation, at least in this very limited sampling, doesn't completely hold up when perusing a sampling of MI images at Marathon sol4131 vs Perseverance sol4787, but still some interesting differences are apparent and despite the better focus and exposure of the more recently acquired MI, it seems like the muddier fines have been cleaned away here. I'm curious whether any of this owes to winds in each locale, inferring that here in Perseverance we might expect better solar panel cleaning events? since if seasonal patterns are consistent the images linked are just about 1 Mars year apart. |

Different indeed.
I wonder if we're seeing the effects of a few tens or hundreds of millions of years of wind scouring on harder than usual bedrock. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

We're starting to see some clouds as we head towards winter. Here's an navcam animation from 4793: This is a stretched difference of each frame from the average of the frames. Hi Fred, The originals have that bright 'half moon' in the lower third of the frames (which I think you chopped off) What is that bright area? -------------------- CLA CLL

Hi Fred, The originals have that bright 'half moon' in the lower third of the frames (which I think you chopped off) What is that bright area? It is caused by the dust of times. ;-) The small hood we have in front optical element only partly occludes the Sun. Therefore, even when the Sun is outside the field of view it will illuminate the dust which causes diffusion and enters the optical path. Most of the dust was accumulated around Sol 1200+ (2007) but during the years the wide have cleaned up the front elements quite a bit.

Taurus, just below pointy end of the Hyades. Kinda random. A rare night comm pass allowed free astronomy, but no moons were up. Still useful as practice and will add a night opacity datum..

Monthly MER Update from the Planetary Society. Also has a nice star photo. I'm wondering what all the proper motion streaks are, especially the sideways ones. Meteors in the Mars atmosphere? |

Marsophile, the steaks directed from 11 o'clock to 5 o'clock are stars trailing during the exposure. Everything else should be cosmic ray hits. |

My guess is that it's an erosional texture as seen in the MI images from the same sol.

This is Jan's 4816 panorama reprojected into a roughly maplike geometry to give a view of the surroundings. The lower right (southeast) corner is still bad in this version. The tracks cross a small crater.

lengthly september edition of the Planetary.org MER update goes into a lot of detail about driving and energy production challenges... plus a huge 15MB "Sprained Ankle Panorama" (why so-named?).
I've never heard much discussion regarding the current state of Oppy's battery charge capacity after all these years, here we are almost 14 years in now using workarounds to so many ageing issues, yet (mercifully) there seem no worries with the batteries! here's a sol4843 stitch anaglyph and crosseye of one section of the upslope dusk images |

Possibly we are becoming blasé about Opportunity's performance, leaving the astounding achievement of the 45 kilometre mark unremarked. Looks like it is going to be a long slow winter for Opportunity with power generation hovering around 280 Watt hours at this time.

Thanks for reminding us, so Oppy slogs past another kilometerstone with no fanfare, not even in Crumpler's latest post from last friday, i think thats equivalent to traversing about 70% around the entire Endeavor ridge, so i guess we got a while before we hit that one, i am perhaps too complacently confident that will happen! to help celebrate here is a stereo of the latest MI pairs from sol4857.
And thanks fredk, that info about the battery was very illuminating! |

This new drive back uphill was discussed in the latest PS update:
QUOTE One option under consideration is to send the rover back uphill to an area near the first way station where the MER scientists have spotted some interesting bedrock.
“It looks like two different colored, bedrock units in direct proximity,” said Golombek. “One area that we’re imaging shows that one side has rocks of a lighter tone and the other has a browner, darker tone and the two units appear to be separated by what could be a fracture zone or something. It’s all dirt, maybe broken up rock that’s been filled in by sand, or who knows?” |

The 4883 drive looks like a very short bump upslope, towards the direction we're looking in the image I posted. We're sitting almost exactly on our tracks from the downslope drive on 4831 (check Phil's map) and the obvious track is from that drive. It's harder to see the track from the other wheels I guess because of the bigger rocks on that side.

Yes, James, thanks! I have been using your images to assemble a photomap base for more detailed mapping of this area. This is still an ad hoc mosaic, not controlled by HiRISE, but it will be warped to fit HiRISE control later, and then the detailed path can be plotted.

Where opportunity is headed downhill there are active sand dunes which would ensure regular cleaning took place. That would be a good location to park opportunity when the wheels pack in. There is an argument for parking opportunity for two years there in any case because of the radio experiment that can be done to investigate the core from a parked lander. There is a plan to launch the insite mission next year to do this radio science experiment, but if this failed then opportunity could perform the radio science experiment whilst filming moving dunes |

Where opportunity is headed downhill there are active sand dunes which would ensure regular cleaning took place. Hmmm... I think that where there's sand accumulation there's a dip in strength of winds. That's why the dunes get bigger and bigger. In the past we have seen cleaning events near clean bedrock. QUOTE There is an argument for parking opportunity for two years there in any case because of the radio experiment that can be done to investigate the core from a parked lander. If there was one I never heard of it. SS never mentioned that. Parking the vehicle for two years would be a major operational nightmare. We have only FIVE rover planners left which would still need to earn a living for those two years, so we would need to find another job for two years. After this forced pause, resuming operations would be quite difficult. It was so when we had to park Spirit for months at a time. I can't imagine what it would be like to resume driving after two years. I liked doing the radio experiment on Spirit, I found it mind bogglingly cool and was part of the team to support it but I hope we can postpone this to when Oppy's wheels fall off or the motors stop responding to our commands. We have tested driving our testbed with only four active drive actuators...

This is hideously distorted because I am not working from a topographic dataset to reproject the images - later, this will be projected onto HiRISE for control. But it gives an impression of the distribution of features around us in mid-December.

You mean those vesicular rocks? Doubtful. They look volcanic if anything, maybe scoria.
That said, I don't know if we've seen any igneous rocks around Meridiani before. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Sols 4937-4943 Lpancam Great work! I have been working on this one as well. I have dibble dabbled with the previous color mosaics alittle bit as well but haven't posted them. Here is what is down of the current one.

Thanks James, those 3D interpolator results are really impressive to see and looks like it must be a pretty involved process.
Here is some comparably lo-tech stereo output (StereoPhotoMaker) of SanMiguel sol4947 (cross/anaglyph/parallel) with its curious vesicles, it's interesting how the apparent 'spattering' of vesicles cover only a portion of the rock that otherwise is of apparently consistent composition throughout.. |

For me, it isn't that bad but for my computer that I built eight years ago, it sure does take a beating sometimes but it pulls through.
The Navcam mosaic on Sol-4934 and 4936.There was a big honkin lens flare that I had to remove in one of the frames. Spent a couple of hours on this, not sure how I feel about it. But I'll go with it. Full Resolution https://www.flickr.com/photos/43581439@N08/...228465/sizes/o/ |

nice job removing the lens flare, that must have left very little dynamic range to work with and explains what I at first thought was a field of ripples just above to the left of the low gain antenna post.
here's stereo of the channel sol4952 complete with banding artifacts compliments of ICE and my inability to get better results from Hugin without a lens profile... |

Yes - looks to be a new but of dust picked up on the optics. I'm currently on Paternity leave - but when I'm back on MER in a few weeks, I'll be attempting to acquire a set of NavCam flatfields using a technique already used on MSL that might end up being rather timely to calibrate this out.

It is not a bug, it is a feature. We got a nice cleaning event, about 100Wh more, so I'm not going to complain about it.

And it is again: Happy Landing Day, Opportunity! It is unbelievable 14 years since landing in Meridiani Planum in the Eagle crater. 14 years, and still roving.
The rover has driven 45000 meters on the surface of mars. Currently it is the 4979th sol for Opportunity, and it is still functioning: hardware, batteries, software. Unbelievable! And if no one notices: For Spirit it would be tomorrow the Sol 5000! (http://www.greuti.ch/oppy/html/filenames_ltst.htm) -------------------- Need more input ...

Nice! And here is a rough projection of Navcam images of the current location (rough because it is not made using a DEM to remove relief distortions) to show the very interesting features here.

Parallel eye. This rock seems more cavity than substance. Perhaps pumice but is there any volcanic terrain nearby? Also note the upturned piece of surface in the background. I wonder if these insubstantial fragments are light enough to be blown by the wind? Perhaps in the past if Mars had a denser atmosphere. (Congrats on that wonderful MI self-portrait, by the way.) |

Thank you Olivier for the kind words.
I extended the Opportunity color image of the tracks with the single Navcam image that was taken during the "Selfie" for more context. Full Resolution https://www.flickr.com/photos/43581439@N08/...171008/sizes/o/ |

My attempt at the tracks from 5002 (plus 4998 as a bonus). First piece of processing I've done in about a year!

https://mars.nasa.gov/mer/gallery/all/opportunity.html
http://qt.exploratorium.edu/mars/opportunity/ From the image download sites, it might appear that Opportunity is taking a vacation to celebrate its Sol 5000 anniversary! At the time of this post, the JPL site has no new images since Sol 5000 and the Exploratorium site has no update since Feb 28. On the other hand, although the amazonaws json site has no images for Sols 5007 through 5010, it continues with images from 5011 onwards. I would guess the gap might be due to the recent MRO safing event. It may be that the JPL and Exploratorium servers are waiting to get images for Sol 5007. If so, that wait may be forever unless the servers are manually restarted. Perhaps the servers could be programmed to probe forward to see if the image dumps continue after a gap. |

I use the JSON site all the time these days. It has been updated to sol-5015 and waiting on the downlink of sol-5016 images.

Very nice panorama! This is a circular projection of it to show the location in a more map-like form.
