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
Oh no, that's really sad news. Having to drive out of the crater just as we were nearing the cliff face...
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.
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.
But Erebus isn't unnamed lol
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?
Guess that damn slope & the slippery terrain was just too much for her....dammit. One hell of an effort, in any case, and safe journey to Erebus!
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.
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?
So, it's back to Erebus. Oh well, at least she has a track to follow now.
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.
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.
Yes, the maximum-age layers remain unanalyzed.
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...)
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.
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
I'll have to go to Mars myself..
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.
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
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.
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.
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."
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
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.
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!)...
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...
-the other Doug
I am so ready to get get back out on the plains in search of the cobble float! Giddyup. I have my list of favorites that were neglected back up the trail. This should be fun.
I'm happy...*
How could we ever reach Ithaca from inside that crater?...
* and back...
THERE you are!!!
(shouts off to the side: "It's okay guys, you can stop scanning Portugal with HiRISE, we've found him..." )
Thought you'd fallen into some abyss somewhere!
What do you hear from SS these days?
Didn't you see the Warning label on MECA?
"Don't try this at home!"
Hey! At my home I'm free to try what I want!
New hazcam pics at exploratorium show no significant movement. I'm thinking they will be giving this spot a name shortly.
Edit: It even looks a bit like they might be trying to back up.
There was a bit of a turn to the left. And http://qt.exploratorium.edu/mars/opportunity/rear_hazcam/2008-08-06/1R271306561EFF90DCP1314R0M2.JPG I'd guess they're doing these late shots to improve the lighting on the rear wheel area. But a few more of these shots and we'll have a nice sunset shadows animation!
Still a difficult situation to get progress there
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:
Significant progress today.

Edit - scooped by Peter!
Very nice indeed - in two respects!
What a straight turn to the left.
Time for one last look at the crater floor before turning and heading out..?
Stu, definitely submit it to APOD!
pheww that's a relief, making some progress at last. Was starting to get a little nervous about that situation.
Glad to see her free from the mess. Let's see if the progress is steady on the next days.
And now back to lurk mode.
(I'm in the middle of my summer vacations and found that the campsite has a wifi connection.)
Hope you're back soon, Tesheiner, fully recharded from your vacation, since Oppy may get lost without the assistance of her best mapmaker!
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. I can't imagine APOD not finding a place for it.
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...
I know... ... but I admit it, I live this stuff, you know!
Ok, just me then.
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.
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.
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.
Agree mostly! It's like the love to your car that brings you to (new) destinations too.
Tried to adjust the cloud GIF with an inverted sky image. It's 600kb http://www.greuti.ch/oppy/clouds.gif
See - thats our emotions projected upon a robot - that makes sense. One might feel sadness FOR Opportunity at leaving Victoria crater (I feel the opposite), but the vehicle itself does not That's the differentiation of lexicon that makes it make sense.

http://qt.exploratorium.edu/mars/opportunity/forward_hazcam/2008-08-10/1F271648925EFF90EHP1214L0M1.JPG
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.
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
Edit: Tman, I'm not quite ready for that tension just yet.
I'm not yet too...
It's no wizardry - is that a common term in English too? - 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.
I'm sad to see Oppy back off from the rock wall, because I think it would have accomplished more science there than it will by heading off now.
I hope I'm wrong!
Yeah she drives http://qt.exploratorium.edu/mars/opportunity/forward_hazcam/2008-08-12/1F271824790EFF90FDP1213R0M1.JPG
Quite striking view on the navcam: http://qt.exploratorium.edu/mars/opportunity/navcam/2008-08-12/1N271825309EFF90FDP1997R0M1.JPG
I don't see why the lower part of the image is so much lighter. It seems to be a real feature of the ground and not some optical effect of the came, as visible on http://qt.exploratorium.edu/mars/opportunity/navcam/2008-08-12/1N271825093EFF90FDP1997R0M1.JPG
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.
OK, it's clearly an optical effect then. I haven't seen it so clear in navcam images before.
http://qt.exploratorium.edu/mars/opportunity/rear_hazcam/2008-08-13/1R271925415EFF90GBP1314R0M1.JPG
<keanu> woah! </keanu> Fabulous anaglyph too Stu. Is it my imagination or are they edging steadily closer to the lowest possible angle of incident sunlight falling on the slope, ie just the upper relief from the slope illuminated? There seem to have been a lot of similarly framed and timed shots of late.
...and I wonder what the cost per sol number's down to now?
I wonder if that shadow shot was timed and planned :-)
I would say yes.
The normal end of drive hazcams were taken as planned at 13:00 LST
Once Opportunity is back on the rim, it would be so cool to capture a movie-like sequence of the rising shadows in Victoria with the Navcam or a Hazcam - just to say goodbye.
Could it be possible regarding power level or capturing in more than one/two sol?
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!!!

Where are you finding those images? The exploratorium URL's that I have are still only up to sol 1621.
Brian
As they are 200x200 pixels they must be from the Pancam Data Tracking site. Nice work keeping us updated Peter.
Which wheel is it that gave them problems on Oppy? As they begin to make their way out of Victoria, has that wheel motor been behaving itself?
It's the left front wheel that got a current spike. So far it looks like it works still fine!
Nooooooo!!!!!!
Touch wood, throw some salt, and please refer to it as The Scottish Wheel in the future.
Or, should we advise Opportunity to "break a wheel"?
Thanks Tman
I don't know if made mention to this already but the crater where Oppy is headed is NOT Erebus, just got an email from SS clearing that point:
"Is the "not yet named" crater referenced (on the TPS blog) here Erebus?
No... it's a different crater, very subdued topographically, but visible in MOC and HiRISE data. We have not made the decision on where to go yet, but it is a leading candidate."
I'm sure you guys can spot it...
OOPs removed my own post for silly suggestion Sorry
Are you kidding? That's Endurance.
See above a moment of madness
So is it the crater that Erebus is embedded in?

Ah, not sure where I should post this, but an image (a pretty decent one I should say) from Opportunity created by an UMSF user was used in a http://www.space.com/scienceastronomy/080820-mars-ice-clouds.htmlarticle yesterday.
Just thought I should mention.
Funny, I just rediscovered that image on my HD two days ago while collecting interesting mars images for 2008 (thus far). Having been one of the world's worst weather observers I have a special place in my heart for landscapes with clouds.
-- Pertinax
Heh. They've used that image on space.com before, in fact I think it's popped up elsewhere as well. Someday when I have spare time I'd like to do a QuickTime VR version of that scene using the PDS IMG files... but I'd have no idea how to colorize it, or fill in the gap between the horizon and the sky.
(Adding: and if you don't know the story of http://apod.nasa.gov/apod/ap061017.html, it was actually an http://www.unmannedspaceflight.com/index.php?showtopic=3324 between several people on this forum, myself included.)
Will it be tosol?
Oops, didn't see the missing pics came in days ago:
960kb: http://www.greuti.ch/oppy/clouds4.gif
Additionally the visibility of the clouds is improved without too excessive contrast, I think.
Did Oppy exit Victoria? if not, then how many sols should we wait? have you got any new photos(after Sol1625)?
There are problems with the pipe that chucks the raw imagery online at the moment. There were some post-drive images on 1627 commanded, but not yet downlinked. Not sure about 1626, and 1625 is online.
Nobody seems to have noticed that on sol 1620, Opportunity had been at Victoria crater for one full Mars year! Keep going, Oppy!
Sol 1630 - successful drive !
Definitely the same way out as in:

Out:
I made and posted this a year ago... seems appropriate to post it again as Oppy prepares to drive out of Victoria Crater...
I guess they choose to use the entry path to get out and to avoid any inconvenience in crossing the dune...
Yes, it looks like yestersol.
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.
Almost
I'm actually excited to see the annulus again!
Flat...featureless...safe.
Roll on Opportunity, new horizons await.

So close... so close...
Is that the Beacon on the &@%¤ side of Vicky that starts to show in Stu's view?
As far as I have heard that the next Opportunity mission would be in looking for any cobblers on the way? Indeed, the during search way would be toward to Erebus crater?
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.)
EDITED
Maybe someone spotted something interesting in an MRO image.
Oppy's going to run away without taking a closer look at the other 2/3 of Victoria's rim?
And Oppy! Please do not forget to capture a "complete" image row of the rising shadows in Victoria before you leave!
I think they're going to go south and look at more rim.
But exploring the entire rim in the same detail we have done so far would be a 2 year long process, and at some point it just becomes stamp-collecting rather than science.
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.
Phil
Is anyone else having trouble getting the latest Exploatorium update to load onto Midnight Mars Browser?
yes.
I think the team is looking for these...cobbles... (sol 658?)
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.
PaulM, you may want to contact Ustrax to create an OLD (Oppy Long Distance) association.
I didn't thought anyone could have challenged Oppy's driving capabilities more than Rui, but you did
BTW, I'm with you but following waaaaaay behind
sol 1632@16:13 LST OUT!
http://www.flickr.com/photos/hortonheardawho/2806187819/
I think Oppy pulled a fast one and did 2 drives on 1632.
Oppy is still clearly on the inside looking out. But it is nice to see into the distance again. Getting a might claustrophobic in that darn hole.
There's some really nice views coming from Oppy as she clears out the memory before heading back on to the plains of Meridiani.
DOH!
I wondered why the "inside" of Victoria was so smooth!
Goodbye Victoria.

Don't think we already left it. That was just the drive out so far.
No - we're properly out of it now.

OK, time to move on! Woo-hoo!

Six wheels on level powder...
Boo Hoo and Woo Hoo

belleraphon1: Of all the "exit and move on" comments I've read so far, yours was my favorite and the most http://www.google.com/search?q=define%3Asuccinct at this point in time.
I have little to add. Let's get on with it... (Is it only me, or does that wheel appear to be rotating in reverse?)
I'm not so nostalgic to leave Victoria's inside. But, when the rover will definitively leave the crater, yes, I will feel more nostalgic (like when the rover reach out of Eagle Crater, it was like to leave a sort of home).

Those are well off the intended NNW track, aren't they? Way over to the east.

Well, since Opportunity has left Victoria Crater, it is time for a new thread.
http://www.unmannedspaceflight.com/index.php?showtopic=5431&pid=124880&st=0&#entry124880
Gulp...
That's actually http://img.photobucket.com/albums/v509/cumbriansky/lookingback2.jpg, isn''t it..?
I couldn't resist doing a http://mmb.unmannedspaceflight.com/OpportunitySol1637Navcam.mov (2.7 MB)
You couldn't resist Micheal … and you're right. Your VR is great .
In the same time, I've produced the panoramic :

Brilliant, thanks Mike!
Also, here's a postcard of virtual Opportunity exiting the crater. Maybe somebody can produce a more refined version.

Sol 1637: Positioning the rover before taking a last panorama from Victoria?
http://qt.exploratorium.edu/mars/opportunity/forward_hazcam/2008-09-01/1F273511017EFF90OYP1214R0M1.JPG
And have a look to this collection of tracks from now, one year ago and two years ago!
http://qt.exploratorium.edu/mars/opportunity/rear_hazcam/2008-09-01/1R273510966EFF90OYP1312R0M1.JPG
It's quite a shock to see the tracks of those long, straight drives again!
AN OPEN "PLEASE, OH PLEASE!" To Steve Squyres and the Rover driving team.
Before you head off on the Cobble Road, could we please have one relatively short drive to Cabo Frio.
Give 'Sputnik' a quick glance on the way and then take Opportunity out onto that promontory.
Just for that chance to take a look back at Cape Verde, Duck Bay and back along the crater rim that Opportunity drove along.
PLEASE, OH PLEASE!

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:
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.
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.
EDIT: rereading the Big Crater thread, I noticed that our fearless Administrator djellison made a pretty solid prediction in http://www.unmannedspaceflight.com/index.php?s=&showtopic=3215&view=findpost&p=69016
I have made a movie of Sol 1630 pictures taken by the navcam during the escape from Victoria. I think there will be more image to come.
http://www.db-prods.net/upload/EscapeFromVictoria-Sol1630.mov
Ant, I like your morphing/interpolation technique for the drive movies!
And the growing shadow ^ ^
Thanks Stu, one of my favorite, very close to what I feel.
Well, may be Oppy's will still be roving in those remote days
Question for the masses here. If an earthling woman had a baby on Mars. Would the baby be Martian or Earthling???
Also. Does anyone have any overhead images of the area to the south of Victoria??? I want to see what crater
they are talking about that they may venture to?
http://www.flickr.com/photos/hortonheardawho/2825774199/
I tried straightening out the ride and addad a little color.
Ant, that last one is REALLY, REALLY nice!
Great works Ant!
The sol1634 colorized mosaic with that clouds and the bit solar effect from above is really a very nice composition!
The only objection I have is the yellowish tone of the image. If you don't mind I changed it a bit - sadly the contrast of the clouds have slightly decreased:
Whaddayathink?
Wow! Those are all beautiful.
Seeing three sets of tracks fading into the martian distance...there's a regular jeep trail out there!
Ow! Many thanks .
Tman : you made more realistic image . Very good .
Superb picture, fourmi 103
Merci
Tracks. New, old and older.

Talk about burning... errr... rubber
Great mosaic, James!
Oh great, James is doing spectacular anaglyphs now, too... I might as well just delete Stereophotomaker from my PC!
Here're some pictures taken on sol 1643 of Opportunity exercizing the IDD: http://nasa.exploratorium.edu/mars/opportunity/forward_hazcam/2008-09-08/
And the plan for sol 1645 (today) includes a bunch of MIs; that would be the first use of it in months! Actually, since sol 1502.
First MIs in four months.
http://nasa.exploratorium.edu/mars/opportunity/micro_imager/2008-09-09/
I take it these are views of the old tracks?
Tracks from 3 times. From left, 2 years ago when Opportunity first arrived, next this past week, next driving in 1 year ago, next last week again. The tracks from 2 years ago went through the worst of the dust storm and are really degraded. Those from a year ago were after the dust storm and look just a little degraded. (I hope I have this correct--please correct me if I am wrong).
Was asking about the MI's - which set of tracks do you think they were imaging?
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.
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.

Nice. You did a better job of compressing it than I did. My good animation was almost 2 megs. I'd love to know how you did that, but now, we are again preparing to evacuate from another arriving storm. cya, next time...
Very nice hit Oppy!
Here's my try with it: 800KB http://www.greuti.ch/oppy/1647clouds1.gif
It's the sequence from 12:00:51 to 02:39. The other is more difficult.
Good luck, Tom!
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...
Beautiful cirrus clouds over Opportunity's landing site (Sol 1651).

I wait for next beautiful animated GIF.
I have forget to upload an updated version of my movie of Oppy's escape from Victoria. It's done
http://www.db-prods.net/upload/EscapeFromVictoria-Sol1630.mov
I'll never be able to change the forum skin, because your GENIUS avatar, and lovely drop-shadowed thumbnails are just too damn good!

Hey, who's said "it gives the forum some profundity..."? It's really a nice eye-catcher!
Sol1651 cloud movie in "false"color:
http://www.greuti.ch/oppy/1651clouds.gif
What do you think? Could it roughly look like that way?
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.
It makes me nervous seeing the wheels churning away like that when I think about how many revolutions they will have to make to get to Endeavour.
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.
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!
I made this comparison between navcam images of wheel tracks taken now and 1 year ago, almost in the same position... to aid, you see some referring points (d location is tentative):
Any driving plans in the works? Still trying to get to the bright patch? Exiting out?
> Any driving plans in the works? Still trying to get to the bright patch? Exiting out?
Today (sol 1659). And based on Paolo's comments I would say we are leaving this site.
Does http://img.photobucket.com/albums/v509/cumbriansky/edge2.jpg bring back any memories, guys..?
And cobbles? You want http://img.photobucket.com/albums/v509/cumbriansky/sept22-pit2.jpg..?
Ladies and Gentlemen, fasten your seat belts because our trip will start soon. Next stop is, mmm, Sputnik? Cabo Frio?
Navcam mosaic from sol 1659.
La lunga crociera ha cominciato! Speriamo di arrivare ben in porto dopo di traversare con successo gli oceani di sabbia....
(Ho vissuto quattro anni a Firenze, é per quello che parlo un po' d'italiano...)
And for anyone without a Babel fish in their ear...
A straight Google translation...
The long cruise has begun! We hope to arrive well into port after successfully navigate the oceans of sand ....
(I lived four years in Florence, is what I speak a little 'd'Italian ...)
Very nice words Oersted.
If Oppy's in an "ocean of sand" (fantastic words, Oersted!) she was in danger of becoming becalmed http://img.photobucket.com/albums/v509/cumbriansky/tracks-sept25.jpg...
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?
Good point. I'm still glad she turned back tho.
So Long Duck Bay. May Oppy's Journeys Lead to Amazing New Discoveries
By seeing the long tracks toward Duck Bay, I'm feeling a little nostalgic. Oppy is closing a page of his life and open one other.
The Sputnik crater on Sol 1661 :

The deepness of Sputnik is quite impressive
> Oppy is closing a page of his life and open one other.
Nice words, ant. I think it's the right time to close this thread and open a new one.
Let's continue here: http://www.unmannedspaceflight.com/index.php?s=&showtopic=5497
It's not unusual. It's a little impact crater called Sputnik.

Using the VirtualDub/AVISynth script discussed in the Phoenix thread, I revisited the Victoria Egress Navcam movie:
http://www.filedropper.com/slomoreallysmall (256x256, 8Mb)
http://www.filedropper.com/slomosmall (512x512, 30Mb)
http://www.filedropper.com/slomo (1024x1024, 117Mb)
The process introduces some weird artifacts toward the bottom of the image, but the rest of the image looks like full-motion video. It's amazing what free software can do nowadays. It even seems to "know" when it's a new drive/sol and crossfades the image.
Pretty cool movie.
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.
http://www.filedropper.com/anaglyph (~5Mb, 256x256)
http://www.filedropper.com/sidebyside (~11Mb, 256x256)
BTW, for those interested in the process, http://nerds-central.blogspot.com/2007/04/synthetic-slow-motion-with-avisynth.html explains how to do this "synthetic slo-mo" and http://stereo.jpn.org/eng/stvmkr/index.html is what I used to combine the two views into stereo.
This was from sol 1625, using the 256x256 navcam images (there were 31 stereo pairs, 2 of which had signal drops in one "eye").
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.

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!
Since we're talking movies, I took a look to see whether MMB's movie-generation facilities still work. Somewhat to my surprise, they still do. Here then is a reprojected version of the http://mmb.unmannedspaceflight.com/MERBVictoriaExit.mov (Quicktime 1.8MB)
Sometime if I have time I'll do an extended version; there's a whole string of great navigation sequences leading up to 'the big one' here.
An improved and slower version of the egress movie:
http://www.filedropper.com/slomo2 (231 Mb, 1024x1024)
http://www.filedropper.com/slomosmall2 (60 Mb, 512x512)
http://www.filedropper.com/slomoreallysmall2 (16 Mb, 256x256)
Wow! MMB is so powerful. How come this capability doesn't exist in the production version?
http://web.mac.com/michaelhoward/iWeb/MMB2.0/Making%20Movies.html I'd love to see you combine MMB's reprojected frames with your morphing technique. That might be pretty awesome actually.
I'll go through the images and adjust the brightness on some of them so that they match a bit better in MMB.
Here's a dramatically lit http://mmb.unmannedspaceflight.com/MERBSol1632Navcam.mov, just before she left the crater. Zoom out and pan down for the neatest view...
For people who want to download a larger version: http://mmb.unmannedspaceflight.com/MERBVictoriaExit_big.mov. This one's sized for my own 1680x1050 display. Please download the http://mmb.unmannedspaceflight.com/MERBVictoriaExit.mov if you're just browsing.
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.
Since we're talking exiting VC...
Some may think this is an exercise in futility, but does this sunlit angle of Duck Bay show Oppy's tracks.
Real or imagined? Whatdoyouthink!?
What are these parts visible in the recent Oppy panoramas:
I guess these are attachment point for the solar panels when these were folded? Official denomination?
Didn’t find it here: http://hobbiton.thisside.net/rovermanual/
Nor on the NASA websites … so where else to turn
Which bit of it? There's solar array mounting pyros on the left, solar cells alongt he middle, and the shoulder of the IDD on the right.
Solar Array Pyro on the left , thanks Doug!
Yeah - pyro-bolts that held the arrays together before deployment.
So concluding this topic, we can say that Opportunity:
came out of Victoria Crater on Thursday 28th August 08 (sol 1634)
left Victoria Crater on Friday 17th October 08 (sol 1683)
