Time for another topic, me thinks.

Posted by: atomoid Jul 13 2017, 01:43 AM

figuring this "Perseverance Valley" thread should populate with said content...https://media.tenor.com/images/c314fb41103bbc10dcad0fd6e52fad0a/tenor.gif??

Here are some stereo views from http://www.midnightplanets.com/web/MERB/image/04786/1P553076526EFFCZZ0P2375L2M1.html 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 http://www.midnightplanets.com/web/MERB/image/04787/1F553164576EDNCZZ0P1121L0M1.html, 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!

That surface does look a little different to my untrained eye. There is work to do here!

Posted by: atomoid Jul 17 2017, 09:55 PM

Perseverance Valley indeed seems to differ somewhat significantly in the bedrock and consistency of the soils, comparing relatively similar filter#2 views from http://www.midnightplanets.com/web/MERB/image/04122/1P494113565EFFCO03P2437R2M1.html with its more pillowy bedrock and angular shards versus the more pebbly and sheared surface seen here in http://www.midnightplanets.com/web/MERB/image/04791/1P553518604EFFCZZ0P2378R2M1.html.

That observation, at least in this very limited sampling, doesn't completely hold up when perusing a sampling of MI images at Marathon http://www.midnightplanets.com/web/MERB/image/04131/1M494925669EFFCO97P2975M2M1.html vs Perseverance http://www.midnightplanets.com/web/MERB/image/04787/1M553162964EFFCZZ0P2976M2M1.html, 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.

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.

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.

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.

Posted by: atomoid Sep 25 2017, 08:23 PM

Thanks for reminding us, so Oppy slogs past another kilometerstone with no fanfare, not even in http://nmnaturalhistory.org/space-science/rover-field-reports-mars 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 http://www.midnightplanets.com/web/MERB/image/04857/1M559369578EFFD0AKP2936M2M1.html.

This new drive back uphill was discussed in the latest http://www.planetary.org/explore/space-topics/space-missions/mer-updates/2017/09-mer-update-opportunity-braves-winter.html

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?”

Popping a wheelie with the RR wheel after a short bump on 4883:


Posted by: monty python Oct 20 2017, 06:33 AM

Wow! That's radical. Don't think I've seen that before. I only see a trail from the wheel on the right. Was it pivoting?

Posted by: fredk Oct 20 2017, 03:13 PM

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

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

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.

Is there a smudge on the Navcam left eye lens? Not visible in the right eye.

Posted by: djellison Jan 18 2018, 05:06 AM

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. wheel.gif wheel.gif wheel.gif
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)

This channel seems to have been pretty much swept clear of regolith including large rocks.

 

Posted by: marsophile Feb 17 2018, 06:39 AM



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.)

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.

Posted by: James Sorenson Mar 5 2018, 05:25 AM

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.

These MIs from Sol5033 (right) and Sol5036 (left) form a pretty good X-eye stereo pair.

The fusion is not perfect because there are small differences between the two images, which may be due to dust movements.

Huh. Wonder if the ring is aeolian deposition around a rock made of unusually soft material that weathered away over time.

Vaguely reminiscent of Spirit's "rotten rocks". Water altered rind remaining as the softer interior eroded.

Curiosity has seen quite a few attributed to gas escape (akin to a small mud volcano or diapir) in a sedimentary environment. Finding one here would provide a few insights into Perseverance Valley. Half crippled, sensor limited, operating on a shoestring budget in the shadow of her bigger relation at Gale Crater, Opportunity just keeps on giving.

Posted by: serpens Apr 28 2018, 06:22 AM

An outstanding update on Perseverance Valley on the Planetary Society page.

Posted by: marsophile Apr 29 2018, 03:43 AM

Thanks for that link Serpens. Very enlightening.

The focus on the origin of Perseverance is understandable. The urge to explain this unique feature is what led them to this location. I would hope though that there would also be scope for Opportunity to live up to its name and do some opportunistic science that might have nothing to do with the origin.

In particular, I find the light-toned deposits on dark rocks fascinating. What is the chemistry of these deposits (as separate from the underlying rock)? Is there anything special about the distribution? Has this material blown down from Winnemucca plateau where there seems to be a large reservoir of the stuff? Is the composition essentially the same as the planet-wide wind-blown deposits? Perhaps some of the answers are to be found in the APXS results from the "Aguas Calientes" target. I guess we may have to await the next conference for those revelations.

South Meridiani apparently hosted some of the valley networks that were formed before the Noachian/Hesperian boundary. If the impact that created Endeavour was into an existing fluvial system, I wonder if its location could explain the uniqueness of this section of the crater rim? Of course it would have been altered by subsequent processes but it might have influenced their evolution.

Fun fact.......5083 I was on shift - and not only did we conduct the first NavCam 360 in a single Sol that I've seen in >a year of Ops - but it's in part thanks to a ExoMars TGO pass on which some of these frames came down!

Still trying to sneak in an upper tier to get a proper 360 without a Horizon cut-off. Hard to convince the science team to spend what bits we have on that.

Parallel-eye. Here it exaggerates the depth perception, which helps show the intricacies of the texture.

What fascinates me is that Opportunity is showing us what was once the interior of jumbled, potentially overturned crater walls themselves made up of material from a Miyamoto ejecta blanket hundreds of metres thick. I look forward to seeing what the science team make of this particular jigsaw.
