To answer Ustrax's querries from the other thread, I think we can now see more of the south west rim of Endeavour and Iazu. In this image I've lined up the views from 1987 pancam (colour on bottom, from Astro in http://www.unmannedspaceflight.com/index.php?s=&showtopic=5503&view=findpost&p=145455) and 2136 navcam (top, from Ant's navcam mosiac):
OT - but relevant to the above...
The spot Oppy's at now is a http://www.unmannedspaceflight.com/index.php?showtopic=681&view=findpost&p=153916 compared to the surrounding region, but over the next 5kms or so there's another 45metres of rise before the drop off towards Endeavour. Much better views to come - we'll get the HOAV yet! Are you listening Stu
But first, there's some fun to be had here at Concepción.
Looking to http://www.unmannedspaceflight.com/index.php?s=&showtopic=681&view=findpost&p=153839 again, what I see is that we are currently at level "-1370" and the highest point is at "-1325" before dropping down to "-1430" near Mini-Endurance.
Ngunn, I was just about to say the same thing. The labels are not very clear, but the contours don't make sense any other way.
Phil
I'm also on the lookout for an isolated hill almost directly south (actually the end of a promontory). My impression is it's not yet visible as we have had recent pancams which I think cover that direction.
I've done a cross-section plot of the elevations along our actual route between Eagle and Concepción, and from there to Endeavour, to the end of the proposed route originally posted http://www.unmannedspaceflight.com/index.php?s=&showtopic=6404&view=findpost&p=153775 This corrects the blurry number 1325 to 1395. Vertical scale 1 m/px, horizontal scale 24 m/px:
You're welcome!
Phil
"Curvature works against us".
On flat ground, horizon on Earth is at 8 kms (I guess at human eyes). Do you know the figure for Mars?
At the pancam height of 1.55 m, the horizon on Mars is 3.2 km away. Another way to look at is is that in 5 km (most of the way to mini Endurance), the ground will drop by 3.7 m due to curvature. It drops 15 m after 10 km distance.
It looks like we can't resolve those rim peaks on the contour map. But the fact that we could see them since Victoria means they're higher than our current elevation, probably by a fair bit. (Perhaps any more discussion should go to the other thread...)
So much to see in these latest navcams. Here's an example of a definite dark feature on the horizon, in front of (part of??) Iazu Crater (lighter band above horizon):
Comment and query copied from the other thread:
I note that the nearest Endeavour 'rim' hills actually rise from some way down inside the hole so we won't see their feet till we're almost there. In the Endeavour Crater thread there was a very nice HRSC 3D view of Endeavour which somebody annotated with elevations. I wanted to look at that again but the HRSC links no longer work for me. Can anybody help with that?
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-01-31/1P318162164EFFAB66P2368L7M1.JPG
No doubt at all about which is rear or far rim...
Edit: And, at least for me, this is already a HOAV!
I knew there had to be a significant up-side to chronic insomnia!!! Beauty & great scientific treasures now in sight, and we few are among the first to ever see such a scene on this world. In the next hours, possibly millions of others will join us.
... and if you stretch the horizon until it begs for mercy you can see just how hilly it is...
Are we still happy with these identifications?
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=15887
Is that big dark peak right of centre (of Endeavour) really on the far rim, and if so what's that beyond it?
Takes me back to Spirit's first winter and watching Gusev crater's walls slowly appear as the dust levels dropped.
Amazingly Oppy is only about 16% closer to the big hills on the near side than it was back in Duck Bay! Once they finish heading south and start moving due east the view should improve very quickly. At mini Endurance the distance between Oppy and the big near side hills will be almost exactly half of what it was during autumn 2006.
Hi all
It seems all I can say when posting here is "brilliant views"
I remember when Columbia Hills was about the same size as Endeavour is now on the horizon and how keen I (we ) were to get there.
Now I've never been so torn between seeing whats at our feet and everything that's up ahead.
Either way everyday from now is going to be brilliant views.
Thanks again to all for the stuff on this website.
Roy F
What's kind of cool is that these images of the horizon were taken 16 hrs ago. Seriously - just 16 hrs ago.
...and I made my pan at 7am, so they were just 8 hours old then?!?! That's fantastic!
(And ESA still hasn't released those 'crescent Mars' images taken by Rosetta years ago. Just saying.)
(at least some cameras ESA flies near Mars have a rapid turnaround: (*cough*) http://webservices.esa.int/blog/post/6/958)
Here are the horizon features plotted alongside another 'inverse-polar' map from this position.
The great thing about this is that the view is just going to get better all the time. Apart from the possibility of losing it very briefly behind local drifts in the next one or two km, we'll always have it, and it will get closer and the middle distance will open up more all the time. Exploration at its greatest, as some guy once said.
Phil
That's excellent, thanks James! Now we can clearly see that the very nearest rim hills (maybe in fact a slumped portion of the original rim?) are still entirely out of sight below the level surface we are looking across. I thought that might be the case from my attempts to decipher the spot heights on the map, but I'm pretty wary of those now. Seeing is believing.
EDIT: Why the interest in those invisible hiils? I think that's the location of some curious shoreline-like landforms we discussed a while ago and possibly a future destination.
Fantastic views! Thanks everyone for putting together these mosaics.
Like many previous posts I am just in awe of both the views we are beginning to experience and the expertise of those UMSF members who take the time and trouble to allow us to see these vistas in such a quick, easy and beautiful manner. A big thank you to you all.
I am trying to keep my excitement down to bearable levels (I have already learnt how tiring the emotional rollercoaster highs and lows associated with these two rovers can be!) so i'll simply ask these two questions;
1 - Are the current power levels on Opportunity any cause for concern re reaching Endeavour? (I just have this nightmare of us running out of juice 5 metres from the rim!)
2 - From the photos above it appears that whilst Endeavour is the larger crater and is our target, i think it would be fair to say it looks as though Lazu has an amazing rim. Would there be anything to be gained from trying to get there as well? (I do appreciate it is a long way away but is there anything to suggest it is significantly different from endeavour?)
Finally, I agree with Teshiner, we are definitely in HOAV area! However, I think that bar might be raised in the upcoming months...
Neil
Neil, Squyres was asked about Oppy's power levels at the recent briefing and he said they weren't a concern.
Here's a comparison between the view at sol 1987 (from Astro's mosaic) with the 2140 view (from James' mosaic). Both at 3x vertical stretch. Stunning improvement indeed for Endeavour west rim/Iazu. And significant perspective change - note white line connecting the west rim peaks. Changes within Iazu as well due to near/far rim perspective change, as I remarked earlier when I posted my long baseline anaglyph.
Hi Centsworth_II
I did realize that Oppy is further from Endeavour than Spirit was at Bonneville and thank you for the comparison map all maps are always welcome especially maps with helpful inserts.
Roy F
Cool. Spirit needed only 68 Sols from Bonneville to the Hills (Sol 86 to 154). I estimate the route to endeavour from conception as 4,5 times the route from Bonneville to the Hills (11.25 km? a little short I think) , that means we only need 306 sols to get there :-) But that's of course a minimum guess, maybe we see some interesting stuff on the road ...
Below the minimum, I would say.
Check the route from e.g. VC up to here and that would give you a better km/month figure.
Time and again we've played the X metres in Y sols means Z progress game.
It never works
Ever.
The old saying "You can have it done fast, or you can have it done right" seems applicable here.
Feels like the road to Endurance again, which is cool
OMG !! This is amazing Astro0 !! We really have the feeling of a progression now.
Oh, yes, that is a great animated gif Astro0!
Cool animation. I starred the whole day long at it, and now I think I glaciers at the Endeavour rim ... ok I starred to much.
But I hope we will get soon a third picture to this animation.
I've been meaning to post this for a while now, and the recent chat has spurred me on.
I've had a go at predicting what Opportunity can possibly see, both now and further along the predicted route. I took the HRSC topo for the area, overlaid a CTX image, plonked down a marker for (roughly) where I thought Oppy was at the time (about a week ago now), and then let ArcMap figure out what's visible for something 1.8 m off the ground at that point. I then tried again for a different point along the predicted path.
So here's the base map for the area. The green dot is my poor attempt at a location.
Pete - chuck that Pathfinder demo of Viewshed in here as well ( I never got around to using it) - it demonstrates the power of the technique.
What Pete has shown ( for those who haven't figured it out ) is that certainly for the next several KM - we're not going to have a sudden OMFG HOAV moment - it will be a gradual progression as we've seen with Astro0's recent flicking GIF.
There are just great. Any chance you could extend the area S and SW to check out the potential visibility of Bopulu and 'south hill' from a little south of our present position?
Did we all notice that the SW flank of Victoria should still be visible? ( with deference to the pinch of salt and all that)
Yeah I'm troubled by the lack of visibility around the marker point too. My gut feeling is that this is all coming down to the underlying HRSC DEM, which is 75 m/px. This is probably too coarse to do a viewshed at the scale that we're interested in. But I've got to admit that this is the first real time that I've played around with this method so I'm still learning the ins and outs. Now if someone had a CTX DEM of round here...
So I'm going to have a bit of a play around and see how things change as the marker moves around. I've got a feeling that I might be 'overinterpreting the data' as they say (ie making it up!). But the idea of moving around and averaging is interesting, and if I come up with anything then I'll put it up. I might even try a little bit of MOLA as well, see if that improves things, as that's what Tim Parker's LPSC contour map used I think.
Pete
Here's an extreme vertical stretch of the hills with a bit of noise reduction from adding frames where possible.
Phil
Something dark on the skyline in this view, though likely not at extreme distance. Is there another small crater in that direction?
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-02-06/1P318164806EFFAB66P2368L7M1.JPG
Good catch, ngunn!
The heading is consistent with the next crater on the planned route. Here's it on Google Earth.
Wow, we've only just got here and we can already see where we're going next!
Concepcion and the Next Crater, seen at same scale, with the IAS viewer...
As long as there is no HiRISE DEM yet ... here is a quick try at creating a single-image-DEM from the CTX image T01_000873_1780_XI_02S005W.
(with the whole DEM consisting of about 10 million polygons which is currently about the limit that my software's core math solvers can handle. So the next project I'm working on is to port and compile my sources into a true 64-bit application such that it can make use of the full 12 GB main memory under Vista 64 (I know, I know I should use a Mac, really -> so maybe in the near future it will be able to generate DEMs with 50-100 million polygons.
some oblique views of the area between Victoria and Endeavour:
Just at that twin crater we might get a better view to the south(west), i.e a sign of Bopulu crater and the hills eastward of its "promontory".
Oh my, very nice...good stuff, Nirgal!
I've been pondering these features, the farther and the nearer, for the last few hours but without having your handle on the subtended sizes. I believed Tesheiner (as one does ) but then couldn't find anything on Stu's Hirise crop that looked like the nearer features. Then again like Tman I thought the downward slope would be starting about where the twin craters are, so wouldn't have expected the ground to rise again immediately beyond. I can't be much use here but I'll stay closely tuned to learn how it pans out.
We will certainly have to keep an eye on those features once we leave this area.
Fredk is right. Althought the horizon feature is at the right heading, it's too small to be the twin craters; those ones, combined, cover about 3.5ş viewed from the current position, while the black feature has only 0.4ş.
That looks highly plausible Phil. How far away is that? Is it on our projected route?
It is about where we start to turn to the east after this long trek south and west (about 1400 m south of Concepcion).
Meanwhile, here is another look at Iazu, a comparison of two sols (cut from a post higher up in this thread). I have labelled four hills, and the way hill D gets displaced relative to the other three suggests it must be on the far rim of Iazu.
Phil
Stu's latest pic (which is a wow!) made me realize something that is stunningly obvious, but bears reflection: All of the geology @ Meridiani is completely buried. It take an impact to bring anything at all up above the sand. This is strikingly different from the other locales on Mars we've been able to see at this scale.
Why?
The soft, sulfate sandstone surrounding us at the surface is swiftly and steadily sanded smooth in the short term.
The relatively resistant, robust rocks representing the rest retain the resplendent relief remaining from the remote realm of real rheology and resurfacing.
Really
Oh, great. Now I gotta come up with a sentence featuring words that start with "Q"??!
Quiescent quiteus, queries quintessential (quixotically?)
I quit!
[EDIT: Quorrected!]
Quite.

Damned if I didn't misspell "quintessential" to boot (Corrected...I hope!)! Argh. Gonna get the letter Q kicked out of the English language for good; I'll let you all know when it's done.

Finally, a use for those defective keyboards from Dilbert.

Referring to the crater that appears on the horizon beyond 'twin craters' -
Ngunn, using the proposed route we've seen from the abstract, I agree that we'd turn east before reaching the "crater beyond twin craters". But nothing stands out for that crater (it doesn't look especially fresh, eg), and I'm sure we'll encounter more similar sized ones on our trek. Of course we have to keep in mind that that's only a proposed route - we're not commited to it. Also the resolution of the proposed map isn't great.
In terms of the view, according to the contour map, the best views will be between the south and east. The rise around "crater beyond twin craters" is towards the SSW, so it shouldn't block our views towards the south to east. I don't know what kind of view we'll get to the SW (eg Bopolu), since I haven't seen a topo map in that direction.
Right, I must have missed that! Very good. That far rim topography is the most distant we can see so far, I assume.
Phil
What's that on the right?
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-02-12/1P318165061EFFAB66P2368L7M1.JPG
Could you be more specific? Nothing jumps out at me.
There appears to be a hill on the horizon extending in from the right margin for about 10 percent of the image width. It's visible in 2 of the 3 filters.
EDIT: You got it centsworth.
Looks like I'll just miss the answer - I'm off for a week's holiday now.
Comparing this with the circular pan from the other thread, this lies in the right direction to be Bopolu crater.
Phil
Here's my attempt at pulling Bopolu out of the haze and jpeg noise. Average of L5 and L7, contrast and 3x vertical stretches:
I guess that's now the most distant bit of terrain we can see.
Phil
I was curious how the distance to Bopolu compares with the distance from Spirit to Gusev's rim, which is roughly 70 km if I'm right. I make the near rim of Bopolu to be about 58 km from Oppy. The far rim of Bopolu would probably be a bit farther than the Gusev rim from Spirit. So since we could easily see the Gusev rim when skies weren't too dusty, it's not surprizing that we can see out to Bopolu.
The new pancams from 2153 show more of Bopolu. Also the visibility is a bit better than on our first glimpse - I guess the dust has settled a bit. I've averaged the L7s and L5s, and pieced the frames together (the central strip is the average of all four overlapping frames):
Very nice, Fred! I hope it stays in view for a while, though it might become less visible when we are in the lower region east of here. Still, around the time we begin to descend we may get better views than this. Now we just need a really good atmospheric clearing! I was just looking back at the early views of Gusev's rim from the Columbia Hills - amazing views at times.
Phil
I see on Google Mars that Bopolu rim rises about 1000 feet above the local terrain, and the crater is about 5000' deep. Google Mars can reproduce the view along the horizon seen from Opportunity. Bopolu is the smaller double bump in the center (left of a larger bump).
What's the tasty morsel in the "upper right hand corner" at http://qt.exploratorium.edu/mars/opportunity/pancam/2010-02-16/1P319509701EFFABCXP2373L7M1.JPG?!
The answer is just a few post before yours.
That morsel is a bit of Iazu - compare it with the Iazu images earlier in this thread.
Ooops! Fredk is right.
I thought that image was pointing SW towards Bopolu but it's actually to the SE.
There's a hill (maybe two) on the horizon to the left here. Is it one we've seen already?
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-02-22/1P318250611EFFAB66P2369L7M1.JPG
That's Bopolu Crater. From these new images, I don't see any more bits of it compared with our last views, so this will be our best view for the time being.
With respect to "Sadly, Arcmap doesn't make such purdy contours!", there are some techniques to improve contour output with ArcMap. This blog post has some tips:
http://blogs.esri.com/Dev/blogs/geoprocessing/archive/2009/09/02/Lidar-Solutions-In-ArcGIS_5F00_part7_3A00_-Minimizing-noise-from-lidar-for-contouring-and-slope-analysis.aspx
If you are using a terrain dataset (a multi-resolution TIN), it is generally recommended to convert the next to lowest pyramid level to a raster and then contour against that raster. It's a balancing act between technical accuracy and aesthetically pleasing contours. If you are using a TIN, same concept: convert the TIN to a raster and select a surface interpolation method depending on the character of the data. Then contour the raster. For "purdy contours", we nearly always make contours from rasters (DEMs), not TINs/terrain datasets.
If you direct me to that elevation data set, I could take a look at it and see what I could do with that data.
And for labeling contours, check out the Maplex Label Engine (go to the data frame properties > General tab > Label engine listbox). The laddering option works well for many situations.
Have you looked into making visibility maps from this data? That would be of interest to this forum.
regards, Michael Zeiler, ESRI
Well I had a pop at the viewshed before, but was kind of limited by the DEM I was using (75 m/px HRSC), and the fact that I hadn't lifted the view off the ground.
So here's the viewshed from Opportunity, from a few weeks back now, from 1.8 m above the ground. It doesn't look all that different to the ones I posted before to be honest.
Well that didn't take too long
Here's the aspect-slope map of the same area as before (Victoria is left of centre at the top), made in exactly the same way as suggested in Micael's link.
Yep, the HRSC DEM is good, but I'd still like a CTX one
Just to show what the underlying DEM looks like for all these viewsheds, here's a couple of coloured hillshades with contours (one with labels, one without). I haven't done anything fancy to make the contours, just whatever the default settings are in Arc. The green dot is Opportunity a few weeks ago.
Back in the olden days, before we had MOLA topography, and back when I was trying to anticipate what we might be able to see after Pathfinder landed, I looked at the visibility of distant objects at the Viking landing sites and realized that local topography is more important than the size of the planet, and submitted this abstract to LPSC:
-Tim.
Very nice view of the distant hills today...
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-02-25/1P319941552ESFABCXP2378L6M2.JPG
Stu pointed to this image - here's a bit of a vertical stretch of it.
Phil
I don't know about that... but here I've subtracted a high-pass-filtered version of the image above from the original. The HPF version was chosen to retain the small-scale mottling but suppress the rest. When it's subtracted this is what remains. A bit fuzzy but a lot cleaner.
Phil
Continuing to squeeze every bit of signal out of that L6 view of Iazu as possible, we have two versions of that image, M1 and M2. They are stretched quite differently, so the jpeg artifacts appear to be uncorrelated between them. So we can reduce the artifacts by averaging the two. Here's the result (after stretching the M1 version to match the M2), with 3x vertical stretch:
Very nice - I like those spiky hills at the right end.
Phil
Phil and Fred,
I didn't make myself clear, so here's a picture (worth a thousand words of clarification). This is a median filtered version of the original image, it nicely cleans up the compression artifacts but (as you can see) makes the peaks and valleys less jagged.
This is certainly a view worth a little more tweaking.
Interesting to see the methods everyone is using.
I understand exactly what you mean, Steve, I just don't know how to do it!
Phil
Mathematically it's possible to calculate the distance from some 'mountain' top by measuring the angle it is protruding above the horizon (even it the foot of the hill is still invisible below the horizon), or vice versa you can calculate the height of the object if you know the exact distance to it.
Theoretically it seems to me it would be possible to do this same calculation on Mars, we can calculate the angle by measuring the number of pixels a hill is protruding above the horizon (total camera viewing angle is known as well as total pixel height of the image). It would surely be only a very rough result, but it might be fun to see how it works out and compares to orbital measurements.
Two problems are that you need to take into account the refraction of light (well known on earth, but on Mars?) and you need to be certain that the horizon you see is indeed the horizon and not some landmark or hill, so the flatter the landscape the better it works.
I don't know whether anyone has ever tried to do this?
Yeah, I did this a while ago for the east rim of Endeavour http://www.unmannedspaceflight.com/index.php?s=&showtopic=5503&view=findpost&p=141528
We can now see quite a bit more, and I estimate we can now see close to 200 metres of vertical extent of the east rim.
Refraction would make the hills look shorter than they really are, so 200 metres would be a lower limit. But I doubt refraction matters too much here since the atmosphere is so thin.
We can't see all of the rim yet, so there's got to be more height to the rim hills than we can see yet. So again 200 metres is a lower limit, but probably not by much.
Is the rim taller or shorter then the Columbia hills? That would be a useful practical comparison. I've tried searching for their height but can't seem to find it anywhere, except McCool hill at around 130 metres or so.
Who knows, Opportunity might do some climbing before EOM. That would be an undisputed "heckuva view", right?
Explorer, your post has prompted me to do some digging back in relation to possible future hills and vistas. I've remarked on most of this previously but here I've collected some relevant images from earlier posts.
First the contour map from tim53, post 113 above:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=20806
This shows the downslope increasing quite sharply near the end point of the yellow line. The view forward should become increasingly spectacular over the last km. or so of that route. It also shows that the nearest group of hills to the south rise from a base that is already well down the slope into Endeavour Crater. We do not even see the tops of those hills yet, so for the moment let's call them the 'invisible hills'.
Next pgrindrod's excellent visibility map from post 120 above:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=20817
The invisible hills are aboult half way up that image and indeed show no green shading.
Now to go a bit further back here is a crop of the Endeavour HiRise image posted by SFJ Cody in post 105 of the Endeavour thread:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=16180
I think this shows the northernmost detached part of the invisible hills (rotated 180 degrees?), surrounded by a shoreline-like feature. (**speculation alert - Endeavour Lake???**).
Finally, a vertically exaggerated view which nevertheless gives a good impression of the vertical extent of the topography within Endeavour, all of which should be visible from the viewpoint in question. This is from Marswiggle's post 121 in the Endeavour thread:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=17360
If someone with the google Mars facility could post a virtual panorama from the end of the yellow projected route that would be just wonderful.
EDIT: One more handy link to add - a zoomable CTX courtesy of Stu, post 117 in 'Endeavour drive, drivability analysis' thread:
http://global-data.mars.asu.edu/ctx/img/P01_001414_1780_XI_02S005W
hi fredk. i'm afraid this is all i've got with me in houston - will it do? it's the biggest i could squeeze in under 1 mb, but if you pm me i could probably email you a bigger version.
If the rim is 200 meters, then it's way taller than McCool, the tallest Columbia Hill. Quite a view!
But from what a PM told me there's no good geological reason for Oppy to climb the rim, is there?
But I'd be happy to settle for just reaching their base one day.
Explorer1 I'm trying to help here. On the side we are approaching from (west) Endeavour doesn't have a rim. There is nothing to climb. We should get the view just by descending gradually across the plain to the point where the ground slopes away a bit more steeply into the crater.
Here's a rough idea looking SE from near Endeavour with Google Mars:
Oh, that clears it up, thanks!
Just in case anyone is following this thread but not Nirgal's 3D from 2D magic don't miss these previews of the 'invisible hills':
http://www.unmannedspaceflight.com/index.php?showtopic=6413&view=findpost&p=156307
OK I've been poring over these horizon images along with my retrojected orbital HRSC image and other bit and pieces from this thread + Google Mars for ages! I am now pretty confident that I have everything identified correctly (or pretty close).
That is a fantastic piece of work James. I did wonder about that part of the skyline beyond Endeavour too. Are we sure it's not part of the Iazu apron?
PS - I wish they'd pan around to the north rim again.
Would projected CTX images be of use? The PDS released images are uncalibrated and unprojected, but I've got the process sorted in ISIS3, it's not too bad actualy, so if someone gives me the ob-ID, I'll get them map projected.
That's a brilliant piece of detective work, James. Really brings the whole scene to life.
I wish we had some names - even just working names - for those distant hills and peaks. Maps are so much better with names. Soon tho, I'm sure.
ngunn,
I don't think the distant horizon can be part of Iazu, it just doesn't stretch that far east. Also, it looks more 'hazy' than the rest of Iazu. Looking at Google Mars it does suggest that we should have an horizon about 10km (ish) beyond Endeavour in that direction.
Doug,
I'd love to have a CTX base map of the area. Not sure how much time I'll have to do any further analysis, but here are some ID's of CTX images that would cover all of Endeavour and Iazu.

Stu,
Rui has named everything around here hasn't he?
James
Anything Rui has not named, will just call it Ultreya A through Z.
I've got those three CTX images downloading (140-250 meg each - and I generate about 4 times that in the CTX processing pipeline) - I'll squirt them out tomorrow...and SEE how hard it is to mosaic them within ISIS...but I wont spend to much time on that. I'll zip up PNGs or something and send you a link.
For the P13 ob - ISIS is happy. For the other two, I don't think the kernels have hit the ISIS Rsync server, so I can't project them reliably. I'm going to fudge it assuming nadir-pointing.
Had you tried searching for their correlative HiRISE's? The pointing would be the same.
It would error the same way- tge kernels are external to the images, and HiRISE data would simply be looking for the same missing data. The kernels are quite laggy getting into ISIS, way behind the imaging data.
There may be others that cover the same area, I just grabbed a few ID's off of Google Mars.
It would be good to have as accurate a map as possible to help with alignment of horizon features - fudging it may just confuse me more than I already am!
Well - anything starting 13 or less is great. I'm not sure they started imaging that way much before it was decided to head there thigh. CRX is 30km wide though - so we might be in luck.
WARNING! If you've never used Mars Global Data before, be very careful. It's dangerous. VERY dangerous. It's the Mars website equivalent of a packet of Pringles or a box of Maltesers - once you start, you can't stop. Oh yes, you go on there thinking "I can handle it, I'll just have a quick look", then you start clicking... and clicking... You tell yourself "Just one more"... click... "Ok, just ONE more..." click... and before you know it it's dark outside, the rest of the family are in bed, and there's a cold cup of coffee on the desk beside you...
Fantastic work James! I can't believe we have come this far, able to see the hills REALLY unfolding before our eyes...
About the names...we all know http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=18432? Ah!
I wasn't discounting your names Rui I meant more 'official' names so we can all follow the journey. Your names are great. You're going to need some more tho, looks like lots of smaller peaks on top of the main hills. Better start researching if any of those sailors had pet dogs or cats...
I've been using most of these images on my route map version.
Here's the top left part of it --the so called "context map"-- where I have labelled all background pictures.
Just making some new slides for my next talk (thanks for the help, James!), thought some of you might find this useful in making sense of Oppy's horizon view...
Bopolu on the horizon!
Amazing, since it's so far away. (about 65 km to center of the crater).
-Tim.
Where, where! Oh, that's unfair Tim.
You have privileged access to the raw images. We here will have to wait for the next exploratorium update in about two hours.
Tim, that's just cruel.
nice but that is one noisy image
quick cleaning
[attachment=21002:clean1.png]
I kinda like the noisy image better. Seems the cleaned image has lost a lot of detail.
Here's a different version... worst noise removed and a tweak to the brightness.
Phil
And a stretched version of the topography. Is there something very faint near the right edge?
Phil
there is always a trade off between noise and detail
gmic dose a good job and so dose a fft
and some of the noise is the jpg artifacts
after fft showing the jpg
[attachment=21011:Screenshot_2.png]
My personal pet peev is the jpg artifacts .the jpg format should be illegal
I'm over here!
Here's my take on the latest view of Bopolu. L6 and R1 registered and averaged to reduce jpeg artifacts. Linear contrast stretch and 3x vertical stretch (bottom). No smoothing/noise reduction apart from what happened during rotation.
I think it's a case of increasing atmospheric transparency-- remember the crisp views of Endeavour/Iazu just a few days ago at Sol 2170. And it's only going to get better...
--Bill
I've taken the image fredk made and tried to do some feature mapping on a reprojected HRSC image of Bopolu. I think this should be pretty close, the Google Mars 3D matches pretty well with what we see (also included) which gives me some confidence I'm in the right ballpark.
Nice job, James! That GM view is really convincing.
What about the view of the hill?
Phil
The views should improve in the coming months because we're heading into winter, when the transparency's best. I doubt the tiny changes in elevation we'll do will make much difference.
We should also take into account that the route will turn due east and head directly towards Endeavour once we go past the twin craters. After that point, the view should also start to become better in terms of resolution.
Slight downgrade and smaller ripples should also help.
I was delighted to find a nice 4-frame horizon pan among today's images and I've assembled a paper copy. Bopulu is on the right and each of the leftmost two frames contains one prominant dark horizon feature. The one in the second frame looks like the feature Phil identified here:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=20656.
From our current position I reckon the twin craters should be about 7 degrees to the left of that, but the two dark horizon features are about 15 degrees apart. In short, I'm not really sure of the identification of either of them, or where (or if) the twin craters actually appear in this view.
Help!!
I get these values from the position on sol 2181. The feature at 181° should be a part of the twin craters.
But it seems to me it's just the left rim of the left crater (from the viewpoint of Oppy on sol 2181) and because of the twin craters cover about 5 degrees in this image your 7 degrees could roughly match nevertheless...
OK, but that's a little unexpected since from fredk's earlier post below it would seem that the twins' most prominent feature is the mound smack in between them and the rest of the leftmost crater doesn't show at all:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=20655
Of course if the feature that Phil identified (tentatively) is actually something rather farther away then a 15 degree angle between it and the twins midpoint could make sense. But Phil's identification was quite convincing . . .
I'm not sure what features are twin craters or if we can even see them yet, but the features I ID'd in the image you posted above can't be the twins. From our current viewpoint, they should've parallax shifted to the left compared to the distant feature much more then they have. So it seems all of these features are quite a bit farther than the twins. I guess it's not too surprizing the twins are hard to see, if they don't have much in the way of raised rims.
Edit - I agree with Tman that the feature at azimuth 181 degrees is about right for Twins.
OK so we have two horizon features. Tim's '181' and the one about 15 degrees to the right of it as seen from here. Probably both are further away than the twins, which may not break the horizon although they should lie close to the 181 azimuth of the leftmost horizon feature. Would that be a fair assessment? Phil's earlier identification of the rightmost of the pair probably depended on your earlier ID of the twins, fredk, so it seems to me that both of the horizon features now still await secure identification on the map. Here are links to the two images in which they appear, a little right of centre in both cases:
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-03-15/1P321808039EFFAC00P2391L6M1.JPG
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-03-15/1P321808285EFFAC00P2391L6M1.JPG
Given the fact that the rover positions are quite accurately known, if the same features turn up in images taken at different sols (different positions), wouldn't it be possible to triangulate the features on the map?
The distance between the L/R pancam/navcam is way too short for accurate measurements over such distances, but if you have images/measurements taken at different positions, you might have a baseline which is long enough to get a good enough fix on the positions of these features.
I don't know whether there is accurate azimuth bearing information for the images (relative to true north, iso relative to rover) or if you can derive it from the relative camera bearing and the rover bearing itself, but otherwise, once you have clearly identified one feature you should be able to get the bearing of every other feature by counting pixels (given that the camera field of view is known).
Yeah, that's more or less what I did when I concluded the original ID's were wrong. We should've seen much more parallax shift between the features. But that was a relative argument. I guess what you're saying is if we have absolute azimuths for each image, we can work out distances for features, if they're not too much farther away than our baseline, and if errors in the absolute azimuths don't dominate.
I've noticed something, in fact two things, in today's images. They're so faint that they may not be real at all but they're in both the L and R views. Looking back I now think I can see them in yesterday's images too. They are a couple of bumps on the horizon about 2 degrees and 3.5 degrees to the left of the dark horizon feature here:
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-03-16/1P321987812EFFACFNP2392L6M1.JPG
I'll try to post annotated images but with my primitive IT skills that won't be quick.
Edit: The left of the two is directly above a nearer dark dune.
Attached (hopefully)
And from yesterday:
Possible ID?
Oops arrows missing, trying again.
I agree there are two very faint features on the horizon to the left of the most prominent dark feature. They are visible in both 2181 and 2183 images. I don't have the software to view your identification files, but my guess is that these features might be the "south hill" features we've been looking for for some time, at about the same distance as Bopolu. Nice catch!
I'm not worrying about the distant-distant features for right now. We'll be at Twin Craters in a week or so, a bit closer to where the slope breaks and with one less intervening feature. Meanwhile, I'm going to be looking at the sand and rock under our wheels and on the lookout for changes afoot.
--Bill
OK, I got to fiddling around with those Pancams from today-- 1P321987621EFFACFNP2392R1M1 and the next one. Cropped, stretched, pasted and enhanced, the panorama ain't pretty, but it does show what ngunn and Fred note. The nearby dark horizon feature, Twin Craters, on a slight rise on the left which drops off to the right, showing a more distant horizon behind the rise. On this horizon is another crater on the right, with a pair of faint hills to the left of it.
Rather like Russian nested-dolls, no?
--Bill
Very nice Bill! That shows the situation really well.
I think I've found a terrestrial analog :
http://www.nat-park.com/mule-ears-big-bend-national-park/
I know the Big Bend region well-- I used to take a holiday in the FtDavis/Marfa/Alpine area many years ago. 10,000 foot altitude, all volcanic rhyolite (sorta a continental basalt).
A personal terrestrial analog during that trip just occurred to me. The drive across Texas is long and for the most part traverses flat, flat terrain. Many miles from the mountains of west Texas-Big Bend you begin seeing the peaks just start to poke up over the horizon and grow over the better part a day, much like the distant craters are doing at Meridiani.
It's been 20 years, but let me see if I can locate old photgraphs and see how far away we spotted the mountains. I'm thinking 20-30 miles, but you know how fish stories are...
--Bill
50 miles certainly isn't outrageous when visibility is good and the target is high. I lived on the south coast of Ireland in West Waterford and could easily see 100-200m headlands to the east about 30 miles away from about 10 meters above sealevel when visibility was reasonably OK. Hook head lighthouse was somewhere between 50-60 miles to the east and it's top (at about 25m at a guess) was below the horizon or close enough that I could never make it out, even with a telescope on a perfectly clear day. It was almost always obvious on clear nights though, strobing just over the horizon.
I also recall a holiday in Switzerland in the 80's when the Alps were an obvious hulking presence to the south when viewed from the foothills of the Jura mountains about 40-50miles to the North. No peaking up over the horizon there - as I recall I had to look up at the peaks even at that distance but memory may be confusing me.
At risk of stretching this thread title completely off the planet Mars, I can't help chiming in. I've seen the Olympic mountains in Washington state from Vancouver on a very clear day, at about 140 km (85 miles) distance. And Mt Rainier, Washington is sometimes visible from Victoria, BC at a whopping 210 km (130 miles). I'm sure people can top these sightings, though - Hawaii or similar islands from the sea? The Andes or other coastal ranges from the ocean?
From my backyard I can see the Andromeda Galaxy... 2 million light years away...
I win
I can confirm what fredk says about seeing Washington from Vancouver. Mt. Baker is the most visible one (should be quite a show when it blows!), but with a little height the others beyond are visible too.
And yes, one can see clear across the Strait of Georgia to Vancouver Island, on a clear day.
But we should really be getting back to Mars now.....
This isn't too bad a digression-- we're relating the Distant Vistas we see on Mars to something we can relate to.
I found some notes on Texas road map which suggest that I started seeing the mountains in the Ft Davis (Ft Stockton, actually) area somwhere to the west of Midland, Texas, which would make the distance 85-90 miles.
Back to Mars: although the air is thin, the dust is very very fine and can be easily held in suspension. The dustiest part of an atmosphere is that part close to the ground. The line of sight to Endeavour and Bopolu is close to the ground for a few kilometers until the elevation starts to drop off. It is amazing how far we can see here.
--Bill
Back on Mars, I made a start at matching the features ngunn spotted. On sol 2181 the drive direction mosaic includes both the new feature and Boplou so aligning it with my reprojected HRSC images is fairly easy. I didn't get a chance to finish making a graphic but I got far enough to think the ID is indeed the high part of the Miyamoto rim that ngunn pointed to.
Here is a (1/4 res.) crop from http://hirise.lpl.arizona.edu/ESP_012820_1780
(1,6Mb) http://www.greuti.ch/oppy/ESP_012820_1780_concep_twin_others.jpg
"Mt Rainier, Washington is sometimes visible from Victoria, BC at a whopping 210 km (130 miles)."
Yes, I've seen that myself, on an unusually clear day! But the rainier the day, the less you can see.
Phil
It does, however, make all the difference for the identification of the 'Mule Ears', so thanks for the update Tman. I'm now back where I started on that, along with James. Eagerly awaiting his graphic.
Ok, upright "mule ears" look definitely better
Southward view on sol 2184 (R1/2x^):
Yeah, they're about 194 and 195 there, which I think fits the Miyamoto rim peaks.
Agreed. It's a flop-eared mule.
To be honest, I couldn't be more lost if I was dumped blindfolded into a blackboard factory with all the lights turned off...
fun -true color ( for the day)
[attachment=21109:green.png]
Here's a crude Canvin-style inverse polar, showing just the twin craters, for sol 2184. (Area is so small that no special projection is needed here.) Pancam azimuths from Tman. The twins are subtending a pretty large angle already, around 7.5 degrees, although we're not seeing much yet. Presumably the rims are not raised. The one bump we can see seems to line up most closely with the central ridge, although I thought the dune on the far right side of the twins looked like the highest point. All will be revealed soon enough...
"It's a flop-eared mule."
Mule? It's my pointy-haired boss appearing over the horizon to find out why I've accomplished nothing all week.
Phil
Accomplished nothing all week? CBC, Slashdot, Fark, The Register and a bunch more beg to differ. Richard Garriott owes you for finding his rover - ask him to tell your boss to give you a break,
In today's Expl. update there're R2 filtered images of the drive direction. The twin craters location got quite a new look.
OK I ended up shifting my identifications slightly from my last post on Bopolu (getting a better fit in the process I think) and then get a nice alignment with the highest peaks on the SE-Miyamoto rim according to GM.
Fantastic work James. In anticipation I did some very rough calculations on those peaks. I think the visible 'Mule Ears' represent the top 100m or so of those mountains at a distance of approximately 80 km. Below that I estimate there is about 900m out of sight beyond the curvature of Mars. We only just see them, both geometrically and atmospherically. Nice.
Lots of new images today... has Oppy been having a clear-out? Cobbled together this - I'm sure others will do better, I just liked the (vague) details visible on the hills...
You mean we'd seen them before, or they were taken sols ago, cos that's what I was meaning.
Cool John, the glimpse of the Miyamoto region from Oppy makes a very nice bridge to Hubble.
The sharpest (ever) image from Hubble was captured in 2003 when Mars came to his close encounter with Earth http://hubblesite.org/newscenter/archive/releases/2003/22/image/d/ (...responsible J.Bell and M.Wolff)
You think Bopolu is even visible therein
For comparison an overview of the region from Mars Global Surveyor and a sharped Hubble piccrop:
I was wondering if there are any orbiter close-ups (if that's not a contradiction) of those SE rim peaks? They'd make another interesting target for Nirgal's shape-from-shading technique.
Time to covering entirely the whole region with MRO! At the latest when Oppy rides the peaks of Endeavour
Folks:
Thanks for the heads-up on the possible visibility of Miyamoto! I hadn't noticed those, even though I have been trying to pay close attention to the horizon as we start rounding this "nose" in the topography.
-Tim.
The horizon view keeps getting better and better. I halfway expect to log on some day and see a view of the back of Oppy's head with Victoria in the foreground and Endeavour in the background...
--Bill
Knock on wood. We tried searching for VC on the latest north-looking pancams (Fredk?) and it was barely visible.
This Miyamoto from Hubble stuff is seriously cool. Has anyone noticed Gusev in Hubble images?
Here is a comparison image that I cobbled together from images I found posted here on USMF. The background and righthand image are from Tman in Post #242 in this thread. The Background is a MGS Context image, the Righthand is a Hubble image. For the life of me, I can't find the Post# where I snagged the Lefthand image-- it is an MRO/DEM-Altimetric image of an MSL landing ellipse at Miyamoto crater.
At any rate:
Background: MGS
Right: Hubble
Left: MRO
All at the same relative scale.

206 FWIW
Can anyone with Google Earth Mars confirm whether HRSC is indeed currently the most detailed orbital imagery of the SE Miyamoto rim? I'm guessing it is since I haven't seen anything else posted.
We really were on a bit of a ridge at Concepcion. The view of Endeavour etc has worsened considerably since then:
Ngunn, I can't speak about HRSC.
But here's the map of HiRISE pictures covering the same area that you can find on this link: http://global-data.mars.asu.edu/
There's just about complete CTX coverage of the whole of Miyamoto. Turn on the CTX imagery in Google Earth(mars), and you're ready to rock.
Great, but I don't have Google Earth Mars. Could somebody post the CTX of those rim peaks?
There is raw data available, but map projected stuff isn't available (and it's not particularly hard, but it is fairly time consuming to make it)

A starter for 10
HRSC offers the best stereo usually ( unless a HiRISE or CTX dem exists ) - but CTX imagery is far FAR better than HRSC imagery.
Well, there they are in the middle one. Thanks Doug. Now - 3D?
Are you there Nirgal?
Here's the area of interest cropped from the browse version. The original has MUCH more detail.
OK we have the Mule Ears identified, but that still leaves 'Rockaway', the nearer feature to the right of them. We've been assuming it's quite close, therefore small, therefore (since it's off the edge of the HiRise) probably unidentifiable with only CTX. However I've been monitoring small changes in the angular separation of the Mule Ears and 'Rockaway' as we move south. The results of some extremely crude and approximate calculations surprised me. I came up with a distance of 9 kilometres. This would make it's diameter about 60m, which should be easy to find on CTX. So I looked for the CTX and checked out what lies about 9km away on a bearing of 198 degrees. Not too far from that position - lo and behold - a small dark spot which appears to have rays. Now I'm only looking at a browse version of the CTX, plus my measurements and calculations are as I say very rough, so I'd appreciate if someone else could check this out.
This would mean the flat horizon we are seeing in front of the Mule Ears and Bopolu is probably Mars-curvature limited, not topography limited, consistent with the contour map. (When I thought 'Rockaway' was much nearer it bothered me that there should be no hill there for it to sit on.)
http://photojournal.jpl.nasa.gov/jpeg/PIA11837.jpg
EDIT It's at the centre of this crop:
I agree with your ID of "rockaway". Here's a closer view of it - it looks pretty fresh:
Yes, the azimuth heading matchs perfectly in your image. Great finding! The rim must be pretty developed.
I have an "not suitable for measurements" image with better resolution" that I'dont know from where it came onto my disk". Here the detail:
Looking to the vertical strips on the image I would say that it looks like from CTX.
Yup http://viewer.mars.asu.edu/planetview/inst/ctx#/planetview/inst/ctx/P21_009141_1780_XI_02S005W
List http://viewer.mars.asu.edu/planetview/inst/ctx#/planetview/results?instrument=ctx&minlongitude=354&maxlongitude=358&minlatitude=-1&maxlatitude=-3
Anyone got the actual distance measured? I only know it approximately from laying a plastic ruler on my monitor screen and using the size of Victoria as a guide.
About 7.5 km from current location to rockaway.
Thanks
Stu, there is another on the horizon of this image http://qt.exploratorium.edu/mars/opportunity/navcam/2010-03-30/1N323231461EFFAEI4P1977R0M1.JPG (Bopolu, plus the other twin peaks)

http://www.db-prods.net/marsroversimages/Opportunity/2010/Sol2197-pancam.jpg
Twin peaks II (Miyamoto crater?) far right, another small crater center.
Close. What you're calling Twin Peaks II is part of Bopolu. Your "small crater" is Rockaway. The "Mule ears" aren't visible in navcam.
The clearest view yet of the Mule Ears, and maybe one of the last for a while as we're now facing eastward.
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-04-12/1P324027413EFFAF00P2409R1M1.JPG
I think I can see the notch in the right one that also shows in James's Google view:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=21125
The distant southern horizon looks surprisingly curved now:
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-04-19/1P324834304EFFAFTQP2413R1M1.JPG
Is this the effect of the regional downslope to the SE ?
There's only one way to investigate that... astigmovision:
Vertical stretch of the curved horizon: EDIT You beat me by 4 minutes Phil!
In the adjacent image to the left the plain becomes also visible behind the dune field: http://qt.exploratorium.edu/mars/opportunity/pancam/2010-04-19/1P324834109EFFAFTQP2413R1M1.JPG
Ohh uhh: http://qt.exploratorium.edu/mars/opportunity/pancam/2010-04-19/1P324833925EFFAFTQP2413R1M1.JPG
Very nice and additionally a new remote (?) crater puzzle
Very nice, Phil. I suppose the most distant part of the flat horizon now coming into view must actually be a fraction of a degree below the theoretical horizon, which ought to be closer in level to the plateau on the right. I'm not used to such views because all the large regional dips in my part of Terra are full of seawater.
Great views! We're already seeing a bit more of Iazu than we did at Concepcion, and as Phil's stretch shows, we still haven't cleared the ridge up ahead.
The perspective has changed substantially since Concepcion. Here's a long-baseline anaglyph combining sol 2160 (Concepcion) and 2215 views. The dark bits in front of Iazu clearly stand out in front:
I agree. Another peak-matching exercise for James. . Does it have an official name? (Looking forward to viewing your Iazu anaglyph when I get home to a computer that doesn't mess up the colours.)
Ah yes, good times... good times.... the old Viking days.
Phil
marsroverdriver today:
"Keep an eye on http://marsrovers.jpl.nasa.gov/gallery/all/opportunity.html for when B-2215 (Oppy weekend drive) images show up: PANCAM got nice images of Endeavour on far horizon"
Finally the distant southern skyline is fully revealed, all the way from Iazu to the Mule Ears.
http://qt.exploratorium.edu/mars/opportunity/pancam/2010-04-21/
EDIT: And in the third image, near the bottom of the slope down from the 'rockaway plateau' to the lower plains, there are a few dark pixels close to the horizon whch could be another middle-distance fresh crater. A wild guess: there is another dark spot about 5 km SE of Rockaway here:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=21169. That one should be on the Hirise I think.
I've pointed to the feature here:
Odd but evocative to see surface relief rising more rapidly now from Oppy's viewpoint. It's a bit like driving across the North American Great Plains & approaching the Rockies.
The view is becoming really beautiful.
I'm wondering if it will be possible to see Santa Maria (mini-Endurance) once we are clear of this local high point.
Wow... I come home from work, log on and see... The Future...
I haven't been as excited by such a view since we first peered over the edge of Victoria Crater.
And I have to be honest... seeing the Hills from top to bottom like that, this is the first time I've actually, truly believed Oppy will eventually reach them.
Fanciful view - and please, no-one say "ooh, the Sun could never be there!" if the viewing geometry is wrong; it's just to evoke the sense of wonder I'm feeling right now...
Speaking generally, James, not literally. I think we're on for Endeavour, but that will be it.
One of my favourite Ansell Adams quotes is:
"Sometimes I do get to places just when God's ready to have somebody click the shutter."
My version:
"Sometimes Oppy gets to places when God's got the details just a little bit wrong, so I rearrange them"...
I think you are absolutely right, climber, though I think it will be more reminiscent of northern Arizona or New Mexico. I think this will be one that would excite Ansel Adams.
(Not that the Everest pan wouldn't. )
I'm really looking forward such panorama!
Meanwhile, I checked the tracking web for thisol and further imaging/driving plans and found this sequence planned for tomorrowsol (2220):
02220::p2415::24::6::0::0::6::1::13::pancam_Endeavour_movie_L257
Any ideas?
