It looks like we had a pretty good drive on 4078 roughly to the east (or NE) and now have a better view down into Marathon Valley:

At first glance the sand in Marathon Valley looks treacherous.

There is a black rock in the left foreground that looks just like an oil glob on a sandy beach (ie Santa Barbara, California). No problem if it is oil, NASA recently demonstrated the ability to identify oil globs by plane or satellite spectral imaging :-).

My first guess would be a stony meteorite with a nice thick fusion crust. Odd looking thing.

Could be quite fresh if that's what it is.

One more wonderful panorama Jan. It remember me when we came from volcanoes in Chile and you come down to the Atacama Plateau. Very peaceful and quiet.

And by the way, you put Sol "1048" in the panorama. Did we come back in time? wink.gif

Lovely view openning up after the 4079 drive to the east:

I think we're seeing Argos along the right edge of that frame, and the large light-toned ridge above centre is the feature to the lower left of the "Marathon Valley" label in Phil's map.

QUOTE
From Private Reubin Field, Opportunity will loop around Marathon Valley on her walkabout. "We have about five stops identified along the north rim, before we circle around to the southern part of Marathon Valley where we see north-facing slopes that will improve our power by the time winter comes," said Golombek.

They should call that view of the rocks on the slope "Rush Hour at Marathon Valley" - nothing is moving but you sure get a sense of movement.

Posted by: atomoid Aug 27 2015, 07:18 PM

..Crumpler curiously calls them "dark float rocks", or perhaps that's just a parcel of geologic nomenclature.. i'm inferring they haven't yet definitively spotted smectite from pancam data and are relying on low res orbital data and best hunches to pick the prospective targets to get a profile.. here's Larry's rendering in native resolution:

Posted by: elakdawalla Aug 27 2015, 07:42 PM

"Float" is a term for rocks that have broken from their source rock, so they're no longer in place; they lack context (except that they probably originated upslope). Geologists prefer to analyze bedrock rather than float when they can, but the rovers are often forced to look at float rocks rather than outcrop higher up because of terrain trafficability issues. What they do try to do is find float that hasn't traveled far, where you can see the scar that it left behind on the outcrop so you be reasonably sure you know its initial position and orientation.

Posted by: centsworth_II Aug 27 2015, 09:43 PM

I was surprised to see that the area of smectite detection by CRISM shown in Crumpler's blog encompasses the floor of the valley almost to the exclusion of the bordering layers of bedrock. But maybe the resolution is such that a distinction cannot be made and the outline around the valley floor is misleading if taken as a hard fact.

Posted by: ngunn Aug 27 2015, 09:53 PM

Larry Crumpler's field reports are always very informative but this one excels in the amount of information in the illustrations. We even have the angles of dip in the foliations within the rocks in view. Foliation, if I'm not msitaken, is a word for layers in rocks where it seems unlikely that they're sedimentary layers.

Posted by: fredk Nov 18 2015, 06:49 PM

There was sol 2847 with some lovely views such as this one, which shows an "opposition surge" at the anti-solar point:
http://mars.nasa.gov/mer/gallery/all/1/p/2847/1P380945762EFFBR43P2445L2M1.JPG
There were some lovely colour mosaics made, see the old thread starting around http://www.unmannedspaceflight.com/index.php?s=&showtopic=7131&view=findpost&p=182549

I agree the new 4200 navcams are stunning. And I suspect we can see the opposition surge again in this frame:
http://mars.nasa.gov/mer/gallery/all/1/n/4200/1N501056509EFFCOOZP1685R0M1.JPG

i really liked the ones in shadow from sol4200 but sol4201 are even better. ICE chokes horribly on the righthand R image for some reason, so here's anaglyph of the other two pairs


"https://en.wikipedia.org/wiki/Opposition_surge", so thats what its called, thanks.. i've noticed this interesting effect quite a bit carpooling when one can actually get a chance to stare at at landscapes on low-angle sunny mornings, its especially apparent in iceplant type vegetation, i thought the effect aside from shadow hiding was just a prismatic reflection in plant epidermal cells but perhaps thats implicit as an aspect of the wiki's very brief coherent backscatter explanation.

You're close, it's water drops or if chilly, could be ice crystals rather on the surface of the blades of same vegetation.

A a german word, but yes it sound right "Heiligenschein" though I rather think of holy or saintly light, also that ring over the head in religious depictions.

We've seen such streaks in many MSL photos. I'm more inclined to think that they are miniature "landslides" of the darker martian sand that sits underneath the lighter reddish coating of iron oxide dust.


Posted by: charborob Nov 29 2015, 03:47 PM

wildespace, it is very obvious, in your image, that the streak results from a "mini-landslide" of fine-grained material. On the other hand, in the Opportunity image, the streak seems to originate from the rock. There doesn't seem to be a source of fine-grained material nearby to account for it (not obvious to me, anyway). I hope we will get a closer look soon.

Posted by: fredk Nov 29 2015, 05:07 PM

It looks to me like there's a source above one of the streaks, circled:


Some material has accumulated in a precarious spot on the rock face and some of it has collapsed away and spilled lower down to form the streak. Similar sources for the other streaks could easily be hidden by the rocks.

I think it was material dropped from a wheel. You can see it as far back as 4223 where you can see tracks near by (at 11:00 from the dark streak):

Posted by: marsophile Jan 21 2016, 09:17 PM



Note the encrustations on the rock at the top that look similar to grains in the dark material, possibly eroding into the dark material. This would suggest the dark material has been around for a while.

[EDIT] Also observe the small white piece near the top that appears to have broken off and fallen onto the dark deposit. (Of course, the multiple RAT grinds nearby may have disturbed this area.)

Posted by: serpens Jan 21 2016, 10:46 PM

A look in the rear view mirror seems to indicate that Oppy churned up a bit of dirt in transit so fredk's hypothesis of a wheel dump looks pretty good.

Stunning mosaics, James.

Clouds drifting by on 4294:


As usual, I haven't properly flatfielded - I just subtracted the average of the frames. So there are many artifacts. Eg, the bright patches on the left side turning dark in the later frames - this is due to the average being too bright there and hence subtracting too dark when the bright patches subside. But the overall trend of movement should be accurate.

Not a great image, but why not an unaltered basaltic lava fragment, ejected from a relatively recent meteorite impact elsewhere? The rocks around it were presumably brecciated and vitrified by an ancient impact, and then subsurface aqueous fluids partly altered the the unstable basaltic glass to clay minerals (devitrified it), so they would look different, even if their bulk chemical composition is similar.

Posted by: jccwrt Mar 2 2016, 12:57 AM

The color and shape of the rock in that first image look more like fragments of the rock type in Lindbergh Mound and the Lewis and Clark targets that Opportunity studied just before entering Marathon Valley proper. Maybe just a piece of float?

Sorry about that, but "float" is also a geological word for a loose piece of rock. Unless you can point to an outcrop of that same type of rock higher up a slope, the only logical way to get a loose rock (too big for the wind to pick up) emplaced on the surface of Mars today is to toss or bounce it in from somewhere else, as via a meteorite impact (violent earthquakes and nearby explosive volcanic eruptions being largely lacking at present). So "just a piece of float" would, if you think about it, probably have just about the same meaning as what I said much less succinctly. laugh.gif

Knudsen Ridge with similar outcrops is a potential contender as the source. A heavily tortured false colour image of the float seems to imply that it is near similar fragments and as the float does not seem to have shattered a local source seems likely.

Well going south is logical. The rover arrived from the west and went down from north to Marathon, in the east there's mostly sand.
So a long term goal might be Iazu crater, located in some sort of plateau, possibly ejecta 'splash' from the impact.
Whatever it is it will be a new type of terrain.
Even though it do look interesting, the question is if they would risk wearing out the rovers bearings which already have shown some problems.
This would be as far as the drive from Victoria crater, so my speculation might be off the mark here.

Edit: Some nice images taken for the area already, though the http://hirise.lpl.arizona.edu/ESP_023237_1775 mention the possibility of the rover ever going there with quite some caution. smile.gif

I agree 3514 was the last time we saw what clearly looked like a DD. Before that only 3182 and 2301 as far as I know.

Of course it can be hard to decide what's a DD and what's a gust sometimes. This latest sighting on 4311 shows no sign of continuing up into the sky, so it may just be an intense gust.

The downward movement is easy to understand, but how would this material get onto the rover deck in the first place?

Posted by: James Sorenson Mar 16 2016, 05:33 AM

Here are two false color animations.





The material is built up over the years from the deposition of dust settling onto the panels that than falls into lower areas on the deck and gets trapped.

Posted by: marsophile Mar 16 2016, 06:11 AM

That may be, but the material looks quite different from the reddish dust. It is dark in color and appears to consist of coarser grains. Has it been altered in some way?

Posted by: serpens Mar 16 2016, 06:45 AM

During the years of Opportunity's travels both the ubiquitous red dust and larger particles of regolith have been deposited on the rover. The red dust settles from the atmosphere in still conditions and is readily winnowed by wind gusts or dust devils and continues on its way. However heavier particles, lofted in the stronger wind events would impact the rover structure and be deposited in the dust traps on the rover deck. The 30 degree tilt and vibration has released some of it in a fascinating cascade, but there was no alteration on the rover deck if that is your question.

Posted by: Steve5304 Mar 16 2016, 05:37 PM

The dust must have a baby powder like consistency and not dust like we think of in the desert.

Posted by: serpens Mar 16 2016, 09:38 PM

Ms Opportunity just got a little put out by Curiosity getting so much attention with Namib Dune. So with around 30 degrees slope being the angle of yield and just a hint of vibration, she turned her rear solar panel into a stoss slope. Pay more attention to her guys or who knows what will happen next.

Guess our guy was wrong but it is pretty close. It would be cool...I wrote a short sci-fi novel in college ...one of the sub plots had a NASA rover check the fate of the Soviet mars 3. Only to discover the Martian finished repairing and were about to.send it back as a biological weapon. The idea is neat

Does anyone have any idea how to determine at what elevation these clouds manifest?
Terrestrially, the mind tends to be tricked by the appearance of large objects in the sky, and I am often surprised to see a cloud's shadow relatively close by.
I would expect local terrain effects to prompt such clouds relative to the crater rim and so they may be relatively low, despite the cirrus-y appearance, or they could just as easily be far higher as the Endurance crater sol269 example seems to imply and prompted by other effects, as no significant terrain elevation exists there, though this is hardly an earthly analogue we have here..

Interesting clouds. They actually look a bit thin to make that much of a shadow. It's tricky to tell much of the shadow is simply dark surface material. I would suggest those clouds look relatively high up and far away, assuming the structures in the cirrus clouds are of similar size as we see on Earth. Maybe another cloud outside the field of view is making the shadow?

Posted by: fredk Apr 11 2016, 09:09 PM

Can you point to what you say may be shadow, scalbers? I'd guess cloud shadows would be very diffuse in the local foreground.

Posted by: atomoid Apr 11 2016, 09:45 PM

found a couple references to clouds observed by http://mars.jpl.nasa.gov/MPF/science/clouds.html being 16 km. MRO http://hirise.lpl.arizona.edu/ESP_034342_1315 some at 42 km. oddly only this old data showed in the search, at least in the fist page, as most hits were about that 'mysterious plume' spotted 2012, so maybe just have to look a bit deeper..



[EDIT] post/pre per scalbers below, hadn't meant shadows actually seen, but was referring to the (just my?) tendency to interpret clouds as bigger than actual, making me suppose the clouds are quite low and thus prompted by the crater rim pushing the airmass above the dewpoint as it passes up over the crater rim, but perhaps the clouds could just as easily be from other interactions. I would agree, there is probably zero chance of seeing shadows from such clouds, at least humanly visible, though visible shadows cast by https://www.youtube.com/watch?v=agj7futqHpM, http://annesastronomynews.com/wp-content/uploads/2012/02/Mars.-A-towering-dust-devil-casts-a-serpentine-shadow-over-the-Martian-surface-in-this-image-acquired-by-the-HiRISE-camera-on-NASAs-Mars-Reconnaissance-Orbiter..jpg, or http://www.space.com/4851-curious-clouds-mars.html may be somewhat common.

Right. I was wondering if atomoid was suggesting a shadow being present in much of the foreground of this image:

http://mars.nasa.gov/mer/gallery/all/1/n/269/1N152063405EFF37B5P1910R0M1.JPG

I agree the shadows may be too diffuse to see from this type of cloud.

Posted by: Deimos Apr 12 2016, 02:00 AM

10-20 km is typical of tropical, aphelion-season clouds. Near the surface, during the day, it is 70-90 K warmer than at night. You really wouldn't expect daytime condensation anywhere near there. Near the poles, clouds levels of a few km to fog are found. There are times when much higher altitude CO2 clouds can be found. Now is the end of water-ice-cloud season; around a month from now is the middle of one episode of CO2 ice clouds, but I'm not aware of any Ls~150 clouds seen from Opportunity. (Some of the early-season clouds seen by Opportunity may well have been CO2.)

It's interesting that the only imaging data available since Sol-4351 is from Mark Powells Mars Images app. I think he is still getting the images for his app from the raw images that are pushed to the Amazon S3 service. All the other data sources seem to be down.

Posted by: fredk Apr 26 2016, 02:17 PM

A reminder that Powell has a corresponding website:
https://www.evernote.com/pub/marsrovers/Opportunityimages#st=p&n=427734aa-49a5-4e52-9ffc-fee2c99bdef2
But that hasn't been updated in a couple of years.

Does anyone know of a web interface to the Mars Images app images?

Posted by: James Sorenson Apr 26 2016, 04:06 PM

I was aware of his Evernote site, but I'm not aware of any other web interface for his app. I'm gonna send him off an email and ask him.
The only work around that I found was to go to the Pancam Tracking site and find an imaging sequence that has been sent down, for example.

http://merweb.sese.asu.edu/merweb.pl?rover=B&sol=1&test=ops&instrument=all&choice=obs_summary&obsidtext=B%20%20%20%20%20%20%20%20%20%20%20%20ops04356p235138%201

Then copy and paste the whole filename but replace /oss to /oss_maestro, sol number and what camera it was taken from ( in this case, Pancam replace in the link with pcam ) as well as change the extention from .IMG to .JPG

Like this

http://merpublic.s3.amazonaws.com/oss_maestro/merb/ops/ops/surface/tactical/sol/4356/opgs/edr/pcam/1P514892533EFFCQE1P2351L2M1.JPG

You can go through the JSON site which is still working.

The air is pretty clear over Endeavour at the moment, and we are getting nice views across to the opposite rim. I thought it might be interesting to compare the images with those from Cape York two Mars years ago, to see if there were any changes such as a new streak. No - no obvious changes (though using the PDS versions might improve the chances). But it might be interesting to check from time to time.

Sorry to go slightly off-topic, but I was looking for the folded-up MER dimensions recently, and couldn't find them. Most sites give the unfolded size, but I am interested in the size when MER was inside the lander during cruise. If anyone here has an idea where to find it... Thx!

There are lots of color variations in the false-color version which I can release as well. I might also get started on a 3D version since stereo imagery was also taken from that spot. I have to subdue those variations when making a "Guestimated" color of what the scene may look like simply because of the filters used, those large color variations would not be as prominent to human vision. The colors off in the distance in the false color version in the crater are saturated light blues, dark blues and some purples, greens and some yellows. I take those blue colors as basaltic in nature,which basalt is blackish. The greens might be olivines. So thats one of the cues that I use when I process my images into picture like this.

Oh and thank you guys for the comments on it. smile.gif

http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=37064, it will interesting to see the current state of the tracks if that's part of the plan, and we never did manage to get a snapshot of that cleanly hewn tree http://www.midnightplanets.com/web/MERB/image/04415/1N520130641EFFCQNQP1826R0M1.html on the way down, which is now the subject of a filter sweep. It seems no pics were taken sol4080, actually its hard to spot but at the right of center in this http://www.midnightplanets.com/web/MERB/image/04079/1N490306531EFFCNU5P1900L0M1.html shot, almost exactly http://www.unmannedspaceflight.com/index.php?showtopic=8058&st=15..
[EDIT 6/29] since the MER team seems to be interested in repeated imaging of this feature, might as well throw in anaglyphs of http://www.midnightplanets.com/web/MERB/image/04416/1P520223741EFFCQNQP2381L2M1.html stitch, anag of http://www.midnightplanets.com/web/MERB/image/04417/1P520312825EFFCQNQP2382R2M1.html and cross of http://www.midnightplanets.com/web/MERB/image/04418/1P520389076ESFCQNQP2596R2M1.html views here, fwiw..

So are we off to stations 3-6? I don't know why Phil's map doesn't display--but follow link to Phil's post.

Hi - sorry, Floyd, what is it that is not working?

Phil


Posted by: Floyd Jul 9 2016, 04:47 PM

Hi Phil--your map displays just fine in your post. I quoted it and thought the map would show up in my post, but only get hypertext and no map. Guess I don't quite know how to repost images here.

My real question is if anyone knows if we are off to visit Stations 3-6 (which your map helpfully illustrated)

Posted by: fredk Jul 9 2016, 06:45 PM

All the recent updates give the impression that we're finishing up at Marathon and are on our way out. We may be heading back to this Mesa area just so that we can exit along our known entrance route. (Just a guess.)

Posted by: Floyd Jul 10 2016, 12:02 AM

That is what I thought, but then we seemed to be exploring the valley. Guess we will see.

why they don`t mention anything about Iazu Crater? I thought that was our huh.gif next destination... huh.gif

Posted by: James Sorenson Jul 11 2016, 05:22 PM

As mentioned, the plan is to travel south along the rim and scope for new science locations. AFAIK, going to Lazu, the decision hasn't been made. That of coarse is a very very long ways off.

Posted by: Explorer1 Jul 11 2016, 07:19 PM

Just to be pedantic, but it's Iazu with an uppercase 'I' wink.gif
I got confused a while back too: https://en.wikipedia.org/wiki/Iazu_(crater)

Thanks for pointing that out. I'm used to seeing the monthly PS MER reports on the main PS blog site, http://www.planetary.org/blogs/, but it seems they no longer post them there. http://www.planetary.org/explore/space-topics/space-missions/mer-updates/ seems to be the place to look.

The senior review (see the Opportunity section) includes some information about proposed future investigations.

Posted by: Julius Jul 13 2016, 08:49 AM

How far from its current location is the small gully which Opportunity is meant to be investigating in the extended mission?

Posted by: centsworth_II Jul 13 2016, 10:11 AM

Are they not referring to Marathon Valley itself as a small gully? Although as gullies go, I would think it's rather large.

Posted by: atomoid Jul 13 2016, 09:50 PM

Since it seems apparent we are indeed leaving Marathon to get going southwards and EM10 refers to 3 future locations with a 'small gulley' as its centerpiece, its puzzling, since the further south of Marathon we go, the more the gully picture appears to dry up, so it must be a small one indeed, the next gulley is another 'valley' about 200 meters to the south which seems the only game in town other than potentially apparently unresolvable small gulleys along the more standard crater rim further south, at least by looking at the http://hirise-pds.lpl.arizona.edu/PDS/EXTRAS/RDR/ESP/ORB_036700_036799/ESP_036753_1775/ESP_036753_1775_MRGB.abrowse.jpg.

[Edit] looking closer at the HiRise, a potential candidate seems to exist where the color section exits the ridgeline on that large light-shaded area just north of the ancient filled-in dune-covered crater two small dark lines descending to the valley floor from the ridge seem to represent gullies..ive added a snapshot.. gullies? or just collections of float rocks..?



On another note, its nice to be up high enough to get a view of that http://www.midnightplanets.com/web/MERB/image/04432/1P521638760EFFCR03P2391L2M1.html again (upper right), which I'm assuming is the item in this http://hirise-pds.lpl.arizona.edu/PDS/EXTRAS/RDR/PSP/ORB_005700_005799/PSP_005779_1775/PSP_005779_1775_RED.abrowse.jpg.

I had suspected that they may do a fairly large color pan here, so I was holding off on uploading that small part of it. Looks like they are! smile.gif
Here is a small false-color preview of that part in a context Navcam mosaic (excluding the Pancam images that came down today, still processing those).

Hello all,
I see your fanatistic panoramas from Oppy since years. Now I search for a solution to view them in real 3D in my Samsung Gear VR device. Has anyone experience with converting panoramas or picture into 360 degree 3D movies (MP4)?
I think it should be possible, but I have no idea where to start.

Thanks,
MoreInput

Posted by: James Sorenson Jul 18 2016, 06:52 PM

I'd be interested in knowing how to do that to! I am not aware of anything other than shape from shading techniques. But ultimately the best solution will always be using both the Left and Right eye images and creating a terrain mesh.

Posted by: Phil Stooke Jul 18 2016, 08:49 PM

This is Jan's panorama from sols 4423-4425 in circular form, and cropped to focus on the pattern of outcrops here. I would like to have a mosaic of images like this covering the whole valley floor - the part we have explored - geometrically controlled with HiRISE orthoimages. I have played with part of it. Of course it would be better if someone on the science team could make it and then release it...

Phil

Sorry about that, it's related to a bug with the blogs landing page where it's not correctly pulling all the blog entries posted elsewhere on the site. I've reported the problem and it should hopefully be fixed soon. You should always be able to find her articles on the blogs landing page. (And apologies for my late attention to this, I was on vacation.)

This has been touched upon in a couple of other threads, such as this one: http://www.unmannedspaceflight.com/index.php?showtopic=7613&pid=231680&st=180&#entry231680

Also, note this video from Sitting Duck: https://www.youtube.com/watch?v=7zW9yISB01Y

Plus this from Herobrine: https://www.youtube.com/watch?v=e76uBfWxD74

Sean has done some good work too. One can combine 3D meshes using stereo imaging from HIRISE (+ MOLA terrain), then adding textures and doing photogrammetry with the rover images. We might consider a thread with info on the actual software packages.

a shame the frames were redacted or subtracted from http://www.midnightplanets.com/web/MERB/sol/04435.html ("image not yet available", right!) and somehow just missed by http://www.midnightplanets.com/web/MERB/image/04436/1P521990081EFFCR03P2393L2M1.html pancams.
