Unmanned Spaceflight.com _ Opportunity _ Leaving Victoria crater

Posted by: fredk Aug 3 2008, 08:50 PM

I guess "to the cape" no longer applies, so a new thread is in order. From http://www.planetary.org/news/2008/0731_Mars_Exploration_Rovers_Update_Spirit.html

QUOTE
...the rover experienced a spike in the electrical current to the motor for its left front wheel, an event ominously similar to what Spirit experienced just before it lost the use of its right front wheel for good back in March 2006... Not surprisingly, the team decided without much debate that it was time for Opportunity to rove on and out of Victoria. "We want to get out of the crater as quickly as possible," Callas said


The plan is to exit via the entry route.

Also some interesting news on the next destination from the same article:
QUOTE
After roving out of Victoria Crater, Opportunity will begin a study of the cobbles on the Meridiani plains. Then, it may head for another [as yet unnamed] crater about 2 kilometers (about 1.2 miles) to the north/northwest of Victoria, Callas offered, provided of course that all revolves well with its left front wheel.

Posted by: Oersted Aug 3 2008, 08:55 PM

Oh no, that's really sad news. Having to drive out of the crater just as we were nearing the cliff face...

Posted by: Stu Aug 3 2008, 08:56 PM

Wow... she really is leaving...

OK, then thanks for showing us such sensational sights Oppy, we're all very proud of you back here. Now, get yourself out again, take a breather in the full sunshine - you've earned it - and then head on for sights and wonders new. smile.gif

Posted by: Tesheiner Aug 3 2008, 09:48 PM

Well, time to leave.
It was becoming really difficult, if not impossible, to get to that wall so I understand the change of plans. In any case, if the left front wheel really stalls I have the feeling it will be "end of mobility" anywhere; here or at the plains. This terrain, Meridiani, is too sandy to drive with a stuck wheel.

Erebus fits that distance and heading. huh.gif

But Erebus isn't unnamed lol tongue.gif

Posted by: briv1016 Aug 3 2008, 10:33 PM

Do they have plans to take a full pan of the wall first or are they trying to get out of there like bat out of hell?

Posted by: nprev Aug 3 2008, 10:35 PM

Guess that damn slope & the slippery terrain was just too much for her....dammit. sad.gif One hell of an effort, in any case, and safe journey to Erebus! smile.gif

Posted by: mike Aug 3 2008, 11:13 PM

Huh. Do you suppose they'll get another chance to look at rock this deep? They never really imaged any of the wall closely. And now they suddenly have to leave. Most mysterious.

Posted by: Bobby Aug 4 2008, 12:10 AM

In the current Planetary Society Mars Rover Update. Opportunity will start to explore the cobbles after leaving the slippery slopes of Victoria Crater and then head about 2 kilometers to the north/northwest from its current location to an unnamed crater. Does anyone have any overhead views which might show which crater they are talking about?


Posted by: BrianL Aug 4 2008, 12:51 AM

So, it's back to Erebus. Oh well, at least she has a track to follow now.






Posted by: nprev Aug 4 2008, 01:06 AM

Gonna go out on a limb here & suggest that that wheel stall was the decision point event. The terrain here is supremely difficult, with occasional slippage rates greater than 90%; getting stuck for good right now wouldn't seem to be in the mission's best interest if they can do other things within the vehicle's capabilities.

Posted by: mike Aug 4 2008, 02:15 AM

I recall them saying they'd go into the crater even if they got stuck there forever. Ah well, maybe they won't be able to make it out and they'll look at the wall after all.. I doubt there's anything comparable out on the plains.

Posted by: Shaka Aug 4 2008, 04:39 AM

Yes, the maximum-age layers remain unanalyzed. sad.gif
But, truth be told, I have searched long for visually distinctive strata, and seen nothing striking.
It was always a small hope - a couple of dozen meters out of 800.
Perhaps we should strive for new horizons.

(sound of piteous sobs and sighs...)

And I have explicitly heard Squyres say they're had no intention of getting stuck and always intended to get in - do science - and get out.

Posted by: Aussie Aug 4 2008, 08:32 AM

A good call by the team. Condition monitoring revealing a high probability of a known failure mode, get the rover to a position where some movement will be possible. High slippage slopes and dunefields are not a good environment and a crater over a kilometer away would seem a touch risky, so maybe they will stick to the annulus. But who knows. The design of these vehicles is a tribute to all those involved and they just keep hanging in there.

Hardly mysterious, unless you really want to see a conspiracy. The decision making process regarding the rovers has always been extremely open, with all the facts laid bare to the interested public. Much more information than we could demand.

Not bedrock, but they want to get out and look at the cobbles. These may have come from much deeper... or far away. I don't know what the thinking is on their origin.

Posted by: TheChemist Aug 4 2008, 09:31 AM

We should not forget that one of the great benefits of the rovers being so long-lived, is that the scientists can do "target research".
It is quite possible that full analysis of data obtained "in a hurry" while traveling south to reach Victoria has lead to important clues that call for
a second more detailed look (i.e. the cobbles in this case). If the scientists judge that the benefits of examining the cape's walls are less
prominent than their new science target, it is not a surprise that they choose to get out and pursue that target instead.

PS. Not to mention the "born to be wild" feeling of roving in the plains, too smile.gif

QUOTE
"Just this past month, we finally found the bottom of that dune unit at Cape Verde and we did that from high-res and super-res imagery," Hayes said. "We've seen the base of the unit we're talking about."

And underneath that dune field?

"Another dune field," offered Hayes. "It might be either be a completely different dune field below it or it could be that the dune field we're looking at was part of a very, very large dune field. You can have dunes running on the back of other dunes, so it can either something like a 10-to-30-foot dune riding on back of a 100-foot dune field or it's another dune field from another time."

Anyone offer a guess as to which super-res sequence shows this?

Posted by: Bobby Aug 4 2008, 03:50 PM

Does anyone have any overhead views of the area to the North of Victoria that might show this unnamed crater. I have a feeling it's not Erebus
and it's another one.

FWIW, I don't see how it could be anything but Erebus.

Posted by: djellison Aug 4 2008, 05:30 PM

That's the wierd thing - Erebus (and Terra Nova, adjacent and overlapping) are both names - but are the only large craters to the NNW.

If, perhaps, they meant to say WNW, then there's a large eroded crater at that sort of range.

Doug

Posted by: algorimancer Aug 4 2008, 05:38 PM

Erebus. A bit boring, not the target I'd have chosen (Ithaca!), but at least the scenery will be changing. In many ways I prefer the journey to the destination.

Posted by: mhoward Aug 4 2008, 06:10 PM

It's been awhile since I've looked at the satellite images, but from what I remember (dunes, drifts, sand) I have a hard time understanding how they could go W-NW, even with perfect mobility. Cobbles are great, but sure would love to see some new terrain. Who knows, if they covered some new ground, maybe they might find some interesting cobbles.

Is this the super-res image of the lower dune field that interested Hayes and Lauren Edgar so much?:

http://marsrovers.nasa.gov/gallery/all/1/p/1576/1P268100469ESF90B0P2534R2M1.JPG

This image is part of a large set of apparently identical sub-frame images and so I assume that it is a super-res image. I would really appreciate it if someone was to process this image and other images of Capo Verde to bring out the details that interest MER geologists so much. The panorama which I have seen which seems to best show details of sedimentary structures is the following pan by ant103:

http://www.db-prods.net/blog/wp-content/uploads/2008/07/panol2-quickview.jpg

I think that this pan shows a sequence of cross bedded strata formed by winds blowing from South to North, followed by horizontally bedded strata, followed by cross bedded strata formed by winds blowing from North to South.

I realise that what I call horizontally bedded strata is actually tillted at about 10 degrees to the South. However what I am assuming is that the whole of the Capo Verde cliff has been tilted 10 degrees to the South by subsidence of the wall of Victoria crater.

On many occasions SS has expressed an interest in looking at cobbles on the plains after Oppy is finished with Victoria. I guess that his reason is that there is not much variety in the rocks of Meridiani and so the opportunity for Oppy to look at more meteorites and at rocks from elsewhere on Mars (such as "Bounce") is attractive.

I think that Oppy's first scientific target after it has left Victoria on its road to Erebus or a similar crater may be an exotic cobble close to Beagle crater described in the following Opportunity Update:

"Sol 875: ... Opportunity used its panoramic camera and miniature thermal emission spectrometer on a distant potential meteorite; ..."

There are nice color and false color photos of this rock in the following post:

http://www.unmannedspaceflight.com/index.php?s=&showtopic=2417&view=findpost&p=61844

The following map shows the general area that Oppy was in in SOL 875:

http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=7283

An advantage of Opportunity attempting to drive in the general direction of Erebus crater is that most of the journey could be accomplished without crossing ridge crests. Opportunity only got stuck in Purgatory because it attempted to cross a ridge crest.

Once Opportunity has passed Erebus crater then this will open up the possibility of Opportunity driving many many km across the very easy driving country it encountered at the start of its mission. Anyone who does not believe that Opportunity can drive at least another 12 km should read the following quote from the latest Planetary Society MER update:

These rovers are about 100 years in rover years, but who knows," Soderblom mused, "maybe they'll live to 200. The fact that they're still making such significant discoveries deep into their missions sort of says – don't give up on these missions when they're halfway through," he said. We need to keep the funding there to let them get all the fruits they can."

Posted by: nprev Aug 4 2008, 08:17 PM

I'd like to see a focus on the cobbles as well. They're interesting, and probably have a variety of origins (mostly actual meteorites or ejecta from impacts, I'd suspect.) Either way, they seem to offer a way to examine materials from places beyond Oppy's physical capability to reach

Posted by: Shaka Aug 5 2008, 05:21 AM

Like these, for example: http://qt.exploratorium.edu/mars/opportunity/pancam/2006-05-26/1P201865458ESF71A3P2417R2M1.JPG
As we rolled by them, I thought it a shame that we didn't have time to poke around in there.
Maybe we'll get another chance on the way back up north. smile.gif

Posted by: Stu Aug 5 2008, 05:51 AM

I hope we'll get a closer look at http://www.unmannedspaceflight.com/index.php?s=&showtopic=4151&view=findpost&p=94173 rocks, they fascinated me as we scooted on past, especially that hard-looking blocky one among the crumbly-looking ones (apologies for the technical terms!)...






Posted by: dvandorn Aug 5 2008, 06:00 AM

Oh, come now, Stu -- you *know* that geologists just made up words like "friable" so's they could say a rock was crumbly and sound all ed-jee-cated while saying it... rolleyes.gif

It appears that there were several superres sets taken in the area of the proposed contact. I think the raw image you provided a link to was one of the clearest examples. The set contained images from several filters, but the L6 filter was most numerous, and also the one most likely to provide the best resolution of these layers. I am attaching an attempt to coax some resolution from them. These are difficult for me, and the official version will be much better than my attempt with the raw jpegs, but I think I managed to improve the resolution of the bedrock somewhat. The talus below the cliff was degraded in this image, though.



It's curious that they suggested that highres and superres imagery helped identify the contact. It was pretty apparent in previous images and panoramas, and http://www.db-prods.net/blog/wp-content/uploads/2008/07/panol2-quickview.jpg that you linked to. Perhaps those images were the highres ones they referred to.

But to be honest, I have to agree with shaka. I've searched dilligently for distinctive stratigraphy/mineralogy, too, and I haven't seen it in the depths of this crater. Finding one fossil Martian dune field overriding a predecessor is a pretty nifty observation for a rover...don't get me wrong. I don't want to marginalize it. This is one for the robotic rockhound textbooks. But, such a thing is to be expected, and is a relatively common occurence in terrestrial rocks. Let's also not forget that there is another story of the rocks being collected by the MER's geochemical instruments, the details of which we have less access to, and which it seems apparent to this observer, that there is a rich story unfolding.

As we all consider the news about the discovery of the base of a dune unit, don't forget the qualifiers published in that update.

PaulM: I know what you are saying about the S-to-N and N-to-S laminations, but this Cape is only one small outcrop. I don't think we confidently know the morphology of these dunes/ripples. Are they barchans, linear, transverse, star, or one of the other varieties? The team may eventually tell us. Surely that is one of the reasons they decided to drive around part of Victoria, to observe the lateral stratigraphic variations in the capes and bays.

Oh yeah, and did I note that they appeared to be friable, as well? laugh.gif

Yes, such an animation would be cool. From the update 02.08 there's an afternoon sun over the cliff around 14:54 LTST/sol1607. The only ground image that matches is from sol1603/11:46. However, the two merged looks nice:

Oppy captured a couple of 6-frame, navcam cloud movies on sol 1614. The best movie had two frames with large dropouts, but the remining four frames show some fascinating cloud formations drifting over Victoria crater. I'm attaching that movie for those who like cloud animations.

Thanks for reminding me, Zeke4ther. I meant to add my voice to the call.

Stu: There is something about the long shadows in the 3D view that transposes somewhat intangible data into an almost tangible visit to Mars.

I'd call it a serendipitous intersection of art and science, and I think, one of the best images you have shared with us. smile.gif I can't imagine APOD not finding a place for it.

Posted by: Stu Aug 10 2008, 07:07 AM

Thanks, glad so many people like it, but to be honest I'd have missed it completely if Peter59 and fredk hadn't pointed it out... I guess I'm just one of many of us who have gotten out of the habit of checking out the MET hazcam images daily... so thanks to them!

That image just cried out to be made into a 3D, and although it's painfully dark and could be a lot sharper and crisper it just looks so, well, human doesn't it? I know flak has been fired in the past for humanising the rovers, thinking of those chunks of metal, glass and circuit board as something other than just machines, but looking at that shadow stretching off down Duck Bay, almost touching the dune field in the centre of the crater, I get an overwhelming impression of sadness from Oppy... this magnificent crater has been her home for so long... she's watched the Sun wheel around its rim, watched the shadows of the cliffs sweep around her as she's edged ever closer to the foot of Cape Verde... and she was so close, SO close to reaching out and touching it... but now she has to leave without achieving that goal. So like any weary tourist who's run out of time and has to head off to another location she's paused for a moment to drink in the view one last time, looking behind her and remembering what she's achieved and seen inside this amazing, beautiful place, even as she stares at the route ahead, and looks forward to seeing new wonders, and sunsets and sunrises from the world above...

It's a robot. Much as I love them, you really can take the personification stuff too far.

A robot that's been spending months essentially stuck on sandy slopes, getting a broken arm, symptoms of a broken wheel, unable to really get to the beef of the science in there. Time to get out an do some sprinting? Bring it on.

Doug

Posted by: Stu Aug 10 2008, 09:56 AM

sad.gif

I know it's a robot. It has no heart, no soul, can't think or feel, but it's come to mean something more to me - and to many people here, I'm sure - than just a chassis crammed with circuit boards and instruments.

Some of us here are engineers and techs, some of us are poets and dreamers. The MER mission has touched us all in different ways. Some have been inspired by the technology, others in the scenery. Me, I've been inspired by the journey, and a stage of that journey is coming to an end. So apologies for attributing feelings to Oppy that obviously can't be there, but it's quite an emotional image that, I think. More than just a shadow on a rocky slope. To me, anyway. smile.gif

Posted by: BrianL Aug 10 2008, 02:17 PM

Stu, I think your comments are spot on. Not for the rovers themselves, obviously, but for the many people who have worked so hard to build and operate these devices. The rovers are the physical extensions of these people, who can feel all these things. Or, to use a religious analogy, the body is on Mars, but the soul is here on Earth.

Keep bringing that humanizing element to this forum, Stu. We can't all be scientists, but we can all be entranced by the wonder of it all.

Posted by: ilbasso Aug 10 2008, 04:00 PM

I think the personification is a projection of our own feelings and emotions onto the rovers. It's a natural and human thing to do. The rovers are physical devices created by us, and as such are projections of our minds and hands and bodies onto another world. Why shouldn't we also project our emotions there as well?

Think of the collective will, the fears, the hopes, the wishes of all the people who created these wonderful devices...and then think about how much time we in the UMSF community have collectively spent looking over the shoulders of these robots these past 4 years. That's probably millions of hours spent "living" with Spirit and Oppy. That's a big investment in psychic energy we have made in them!

I feel confident stating that we would not be imparting "feelings" to Spirit and Oppy if they did not have cameras on them. We can't identify with sensors. The photos make us see these rovers in a REAL place.

I also think the mobility aspect makes them somewhat easier for us to identify with, too. For example, I haven't heard much personification going on about Phoenix. We liked Sojourner and called it cute, but we never said the same thing about the Pathfinder lander. (Do we think of the rovers as "pets"?) We like the probes that can reach out and touch things, but again the identification is increased if the probe can move around to get into position.

I have seen some imparting of emotion to space probes (I remember Time Magazine calling Pioneer 10 "plucky"), but again we don't invest them with the same identification as we do the rovers - maybe because they're not sharing our vantage point of 1.75 meters above the ground.

So my opinion is that it's the combination of cameras, mobility, longevity, interacting with the environment, and seeing things from a human point of view that makes us see Spirit and Oppy as friends, fellow travelers on incredible journeys.

Hmm, the new tracks from the last drive are odd. Hope this slide of the left front wheel is only due to the (particular) slippage of the left rear wheel.

Posted by: BrianL Aug 10 2008, 08:19 PM

I'm also not sad to be heading out. To be honest, as much as I was relieved to get out of those potentially rover swallowing dunes when Oppy first hit the apron, I find myself missing the almost daily tension that accompanied that journey. I'm looking forward to new sights, new adventures as she makes her way... sorry, as it makes its way to places unknown. Ithaca

It's no wizardry - is that a common term in English too? smile.gif - with PhotoShop.
A cloudless sky image, that comes the exposure/illumination of the cloud image as close as possible, has to be inverted (whitish comes blackish and blackish comes whitish). Then this inverted sky image has to cover up as layer 1 the cloud image with (here) 40 percent. Then you may working additionally some adjustments for better contrast of the clouds.

QUOTE (akuo @ Aug 12 2008, 10:24 PM) *

In both the images you linked to it's the same optical effect causing the lighter areas. With the steep slope we're often looking into the sun on these shots and we're seeing some glare onto the camera. The two images overlap a bit, and in one frame the overlapped region is light and in the other it's dark, so it can't be real surface brightness.

Posted by: Tman Aug 12 2008, 09:40 PM

There's another angle of this illumination http://qt.exploratorium.edu/mars/opportunity/navcam/2008-08-11/1N271649704EFF90EHP1997R0M1.JPG

Maybe a mirror effect from an optic part that causes some mixup in the exposure.

Posted by: akuo Aug 12 2008, 09:44 PM

OK, it's clearly an optical effect then. I haven't seen it so clear in navcam images before.

Then hours later at 16:35LST another rear hazcam shot was taken, and taken at a higher quality.

For approx $20m/year, you get about 710 sols (355, twice ) - about $28,200 per rover per sol.

The orig 90 x 2 sols for approx $850m was about $4.7m per rover per sol



Posted by: nprev Aug 14 2008, 01:38 PM

Just by way of comparison, the cost of a full fuel load for a heavy jetliner (747, 777, etc.) is right now around $166,000. That's a bit more than 50% of operating costs for a day considering labor, etc. So, the bottom line is that the amortized costs of running the rovers this long are comparable to that of running a very small (two-ship fleet) regional airline; what a great deal for the taxpayers!!! smile.gif

Well maybe.

But I would have thought a longer exposure while the wheels were in shadow would have been better than doing that if it were needed. Then you would have a nice diffuse illumination with no shadows of the wheel itself obscuring part of the ground.

No, the latest for sol 1628 shows we're at the same site as on sol 1625.

Looks to me like there was supposed to be a drive on sol 1627 but it didn't happen, I don't know if that was aborted or if there was a change of plan (or if I've misread the database).

The next drive is planned for sol 1630. I'd be surprised if Oppy exited Victoria on this drive, I would imagine they will get close to the top before having a short drive across the lip.

Well, that's not really a surprise, is it? They originally chose this spot as the safest way in and out of the crater. Then they did the "toe dip" and backed out to prove they could exit before going deeper. They had proof-positive that Opportunity could climb out here without difficulty. Unless they had been able to drive inside the crater to a different bay, this was almost guaranteed to be the exit point.

Well my original point still stands, anything in those directions would involve the old sand dune zig-zag.

But it brings up another point. What the heck is there to investigate in those subdued craters? At least Erebus had some outcrops and rock exposures to examine. But I can't see the point of going to what amounts to a very large Viking Vostok Crater. (But I'm sure they have some goals in mind that we will soon be made aware of.)

What the heck is there to investigate in those subdued craters? At least Erebus had some outcrops and rock exposures to examine. But I can't see the point of going to what amounts to a very large Viking Vostok Crater. (But I'm sure they have some goals in mind that we will soon be made aware of.)

The hope must be that they expose different layers in the stratigraphic column.

But look out beyond the big crater WNW of Victoria - there are other features beyond it (plus various cobbles en route, no doubt). A cluster of small fresh impact craters (probably secondaries, and so maybe accompanied by exotic ejecta), and eventually a spectacular crater that looks more promising than Victoria as a possible long term goal. So there's a longer term goal, and intermediate steps with a possibility of new exposures. There's no way I'd want to go back to Erebus.

If you are talking about that big one two "endurances" due west, it does look very appealing. The slopes appear (admittedly to my untrained eye) drivable to a deeper level. However, with the strong possibility of an impending wheel lockup, I've pretty much put long term (at least, long distance) goals out of my mind.

Posted by: PaulM Aug 28 2008, 07:53 PM

I think that it might be possible to send Oppy far further than anyone imagines.

My reason for thinking this is that Oppy originally covered the 3024 m between the heatshield (SOL 359) and Voyager crater (SOL 432) in only 73 SOLs. In this period Oppy travelled on average 41.43 m per day. This included stopping off from time to time at interesting locations such as Vostok crater. On driving days Oppy covered up to 140 m. If my maths is correct this means that Oppy might be expected to drive 15 km per year across the easy driving terrain around Endurance crater.

I expect Oppy to take at least 6 months to traverse the dunes of the etched terrain again. However in 2.5 years time I expect Oppy to be 35 km North of Victoria crater. I believe that this is the distance that one of the Lunakhod rovers drove on the Moon in just a few months.

I wonder if Oppy could reach the clays below the gypsum rich sandstones it is currently driving upon if it was to drive 35km North of its current location? I wonder how far the potential MSL North Merridiani landing site is from Victoria crater?

I realise of course that the problem is that one of Oppy's wheels if likely to fail long before the 2.5 years have passed. However I hope that MSL's wheels are stronger than MER's wheels and that MSL will be able to drive 200+ km in the 10 years that MSL is likely to survive on Mars.

That's the pile just off the Northwest edge of Erebus, right? I was surprised and disappointed when they drove on without checking that pile out. But if Opportunity is not going back to Erebus, it is not going back to that mother load of cobbles.

The problem in attempting to reach Ithaca crater is the dunes, not the distance. It would be much easier to travel the same distance to the North across a parking lot. Even if there is no obvious target to the North it would still be worth travelling North to sample steadily lower strata in the Merridiani's 700m thick stack of gypsum rich sandstones.

Well, at the risk of coming over as a rover-hugging over-sentimental kaftan-wearing melodramatacist, I'm sad too... it was a heck of an adventure getting to and then into Victoria, one none of us here will ever forget... but Oppy has work to do elsewhere, and who knows what fascinating new sights she'll see? There'll be more dust storms to endure, more glitches to overcome, more challenges to face, I'm sure, but our gal will keep going until the last weary whirr of her wheels.

Well hey now here's some good news:

QUOTE
Mars has apparently gifted Opportunity, once or twice again in August, with wind gusts that have cleared some dust build-up on its solar arrays. "You can't exactly tell when these things [gusts] take place," noted Matijevic. "All you can tell is from inference that the vehicle is producing a little more energy than it was the day before." In any case, as the month progressed, the rover's power production levels soared from 380 watt-hours to 620 watt-hours.

Posted by: brellis Sep 2 2008, 02:05 AM

This normally quiet lurker has a few questions as Opportunity leaves Victoria crater. I'm going to try to answer them via Google.

How deep did Opportunity make it into Victoria? How old are the formations at Cabo Verde? From this http://space.newscientist.com/article/dn13775 on the shoulder problem:

QUOTE
Bathtub ring

The rover had just come from studying rock layers exposed within the crater walls, including one particularly eye-catching band that formed a bright "bathtub ring" around the crater's inside.

But despite driving more than 40 metres down into the crater – representing a vertical depth of about 8 metres – Opportunity spotted nothing but the same type of sulphate sandstone that it had seen everywhere else on its journey, Banerdt says.

Even layers of different colours appeared only to have either a courser or smoother texture that reflected light differently. Still, scientists are now studying the spectrometry data to learn if the layers also contain minute chemical differences that would reveal clues about the region's ancient history.

"There's all kind of pieces to this puzzle, and there's a lot of them that haven't clicked into place yet," Banerdt says.

Scientists have learned from looking at the crater walls that hundreds of millions or even billions of years ago the area was an active dune field, with winds moving either north to south, or south to north – much as they do now.


How deep is Victoria crater? 70m, according to the http://en.wikipedia.org/wiki/Victoria_Crater

My questions for more informed UMSF members: how deep did we get? From AJSR's report:
QUOTE
It took Opportunity just about the entire month of August to complete the series of drives that covered a total of 50 meters (164 feet) and took it back to Duck Bay and out of the big crater it has been studying for years.


That would imply about 9 or 10 meters deep into the 70m crater.

Was the "Bathtub ring" all the confirmation Squyres et al needed to confirm the relationship between Victoria and Endurance?

Thanks smile.gif

Posted by: CosmicRocker Sep 2 2008, 04:43 AM

brellis: Comparing Opportunity's deepest excursion from Tesheiner's route map to the http://marsrovers.jpl.nasa.gov/mission/tm-opportunity/opportunity-sol1272.html, it appears that Opportunity roved approximately 8 meters vertically below the rim of Duck Bay. The 70 meter total depth looks about right, too. The contour lines on that map are 2 meters apart.

Regarding the infamous "bathtub ring," that's a longer story, and there is not a simple answer to that very good question. The term "bathtub ring" has been used numerous times in different contexts by team members and science news writers. It has not always referred to the bright band of rocks seen around the circumference of Victoria. IIRC, the term was first used by Steve Squyres to describe a geochemical horizon the team was looking for when Oppy first approached the crater...the upper extent of the blueberries (hematite concretions) in the sulphate cemented sands. The term was later used to describe other approximately horizontal layers or boundaries that potentially intersect the hole in the ground that we know as Victoria, and which might prove to link the observations made at Endurance Crater to observations made at at Victoria.

We've seen some rather provocative similarities in the rocks from both craters, but also some differences. An important piece of the puzzle are the geochemical gradients in Victoria, which we know little about. I would expect some news in that regard to come out in the LPSC abstracts this spring.

Posted by: brellis Sep 2 2008, 06:14 AM

Thanks for the schooling, Cos.

How much is known about the deeper layers inside Victoria? Was it determined previous to the wheel zap that the potential returns
would diminish below the 8-meter level? Or, have we left behind some unsolved mysteries in the depths of Victoria?

I ask all this as a http://www.unmannedspaceflight.com/index.php?showtopic=3215&hl=ithaca fan. I love seeing Oppy back out in the open field, and I'd love to see her go much farther across the plains, reaching another impressive target.

The MIs are not of tracks. It looks to me like they are of the circular impression made when one of the spectrometers is pressed into the surface. I wonder if it's a fresh impression or if they have relocated an old one.

Posted by: Tesheiner Sep 11 2008, 07:20 AM

Fresh one. The IDD is positioned at a sand drift built up on the rim to the right of the entry/exit path.

A series of 6 navcam EDN frames were planned for a sol 1647 cloud movie. They came down recently along with 6 others taken approximately 13 minutes later.

CODE
Sol   Seq.Ver  ETH ESF EDN EFF ERP Tot  Description
----- -------- --- --- --- --- --- ---- -----------
01647 p1588.03 6   0   6   0   0   12   Unexpected sequence!!!!
01647 p1588.03 6   0   6   0   0   12   navcam_cloud_movie_right_eye_pri_57
I think the extra set probably corresponds to the "Unexpected sequence!!!!" record in the pancam database.

I was going to post the movies, but I think someone else will do them better wink.gif, so I'll hold off.

I'm sure that someone with a nice flatfield for Oppy Navcam images will improve this, but here's both sequences.
Sorry for the slight distortion from the original frame size but you get the idea.

It's the sequence from 12:00:51 to 02:39. The other is more difficult.


Good luck, Tom!

Posted by: CosmicRocker Sep 13 2008, 06:34 AM

Thanks, Tman. We are comfortably away from the hurricane, in central Louisiana, and I am hoping to go home tomorrow. As far as I can tell, the storm is much less intense than the various media are depicting it as. Some of them are interpreting this hurricane's "eye" as the large hole in their radar map. It appears to me that their radar can not penetrate to the center on the storm, hence the hole in their radar. I can't see any "eye" in the satellite imagery. There's a breeze here, and a little rain. The reporters are blowing it out of proportion.

If earier reports are correct, our home was seriously damaged by wind, and then levelled by the storm surge. No way... Stay tuned...this is fun... wink.gif

It looks like they are trying to just push on through this sandy material at VC's rim to get to the light soil patch ahead.
Here's a four camera animation of the wheels digging/driving through.



Let's hope they make it out and can get on with driving to Endeavour Crater (EC). smile.gif

Posted by: BrianL Sep 20 2008, 03:09 PM

I'm sure there will be times of churning on the way to Endeavour. Lots of ripples and some will be soft and embeddable (new word). I think the driving team has so much experience now in these conditions, they aren't afraid to push things a bit. They've gotten both Oppy and Spirit (with her bum wheel, which could happen to Oppy) out of some pretty nasty jams. Perhaps they are even testing one of the new driving techniques that SS spoke of. No more zigging and zagging around ripples, Oppy will just bull her way through.

Posted by: brellis Sep 21 2008, 01:05 PM

AstroO - great work on those movies.

Now that they're "hitting the gas" wouldn't it be great if they could get Oppy to "peel out" on it's way from Victoria!

D is probably under the deck in the 1286 navcam. I also think that this place is seeing too much traffic. We need to get a traffic light installed.

1659 has been a good sol on Mars. Yanked Oppy from the ripple and covered about 10m. Yes, I know it is not 100m, but at least we have "proven" that in case of an embedding event she can be out in a single drive. Both because we are near VC rim, and also because we still need to set our minds for really loooong drives it will take some time to see the first 100m drive.

I'm not so sure. It was clearly a deliberate manoeuvre into a deep ripple, so perhaps it was a test of the latest autonomous driving /anti-slip functions? RoverDriver's said there are sure to be "embedding events" out there on the plains in future; 100m worth of driving into the same dune, Purgatory style, would be Bad. Automated backing-out if embedding's detected, perhaps?

This was done intentionally. No we are not crazy. There was a pretty compelling IDD target in front of the rover but the excessive slip prevented the rover from getting there (we were about 1.5m short). We knew very well this could have resulted in a mini-embedding event but believed the risk of getting stuck there permanently was very low.

On a previous drive inside VC, it turns out that not only did Opportunity take a "movie" while driving, it took the movie in stereo. This movie has a lower percentage of correctly interpolated frames than the egress movie because the images were taken farther apart and downsampled to 256x256. But that doesn't really matter, since this is a FULL MOTION STEREO MOVIE taken on the surface of Mars. That is truly astounding. All we need now is color images and IMAX resolution. smile.gif

Hmmm, I don't remember any intentional movie frames taken during the drive. What it looks like is the visual odometry frames we take whenever we need to evaluate slip. What sol was this? What frames did you use?

Posted by: jekbradbury Oct 8 2008, 02:39 AM

This was from sol 1625, using the 256x256 navcam images (there were 31 stereo pairs, 2 of which had signal drops in one "eye").

OK, if these were 256x256 they were the Visual Odometr images as I had suspected. They were taken at each step of the drive.

I fired up MMB today and noticed that the two data drops I mentioned have been fixed. Here is a new version of the stereo movie, with the two new images as well as with settings tweaked so that there aren't any straight fades between frames. I also doubled the framerate, so this is now approximately 500x realtime instead of 1000x.

Hi,

I'm really impressed by the quality of the work you guys are doing here, and by the discussion level on the few topics I've lurked here for a few days now.
I first-post here, cause seeing Oppy roving on Mars in this short movie blew my mind ! And I guess you've already done a long movie of her full drive from the beginning. I've been searching it for a few days, but didn't find it, so I ask you, where is it please ?

Posted by: jekbradbury Oct 14 2008, 01:25 AM

I haven't been here long; the movies of Opportunity (and Spirit)'s entire progress have been produced by many others, including NASA/JPL. An example of an early one of those is http://marsrovers.jpl.nasa.gov/gallery/video/movies/opportunity/323Sols.movie.mp4. In these movies, the images come from the hazard cameras instead of the navcam, and the rover appears to jump from place to place. The technique I used could not be applied to the complete mission for two reasons: one, Opportunity has not take the necessary pictures every few decimeters for the entire mission, and two, it takes hours to process the movie for just one sol's worth of images. If anyone knows of any other optical navigation frames that seem to make a movie, please post them!

I applied the morphing technique to mhoward's reprojected movie, as he suggested:

http://www.filedropper.com/slomo-projected-large-fast (30 Mb)
http://www.filedropper.com/slomo-projected-medium-fast (9 Mb)
http://www.filedropper.com/slomo-projected-small-fast (3 Mb)

I actually prefer the nonprojected version since the whole point is to show the rover's motion, and reprojecting the frames evens this motion out and makes it seem as if the rover is driving in a parking lot. However, since the navcam is pointable, reprojecting the frames allows for a change in pointing without a jumpy video. This combined with the ability of MMB to export a video which itself changes pointing could create some great clips.
