I'm a newbie here, but not enough of a "newbie" to appreciate the good work you do here. Great image. Looks like Spirit has it's work cut out for it. It would be cool if Spirit could get a good pic of it's heat shield inside that crater and perhaps some rock outcrops like Opportunity is looking at.

Is it possible to update these maps everyday?
Besides maybe an image or two a day with the updates, they appear to only be releasing synthesized images in batches at the press conferences, which are now once ever two weeks. So, write 'em a letter requesting a daily route map, hopefully they get enough feedback to implement one.
.....talking of updates, where have the new images from Spirit and Opportunity gone?

I wish JPL would put out a zoomed in map of the hils with their intended route on it. Last images I saw seemed to indicate Spirit is on the move again but it's hard to know where they're headed.
They're basically heading up the ridge toward Husband Hill. They've not made a lot of progress though - infact, as I read it -

Spirit's path from Clovis
http://s04.imagehost.org/view.php?image=/0721/Spirit_path_225-306.JPG
From space.com:
November 23
Mars Rover Spirit Takes a Brake
Busily surveying the Columbia Hills at Gusev Crater, NASA’s Spirit Mars Exploration Rover continues to suffer a bit of a “brake down.”
Rover drivers at the Jet Propulsion Laboratory (JPL) in Pasadena, California continue to deal with Spirit wheel and brake issues. While surpassing its original warranty, Spirit has intermittently sent information in recent weeks that the brakes on two wheels were not releasing properly when the rover received commands to set a new course.
Recent images relayed by Spirit’s navigation camera show in graphic detail what ground operators are dealing with. A westward view from the robot shows the effects of dragging its right front wheel, explained Leo Bister, Spirit mission manager.
The image shown here was taken on November 19, during Spirit’s 313th day of martian operations as the rover drove backwards for about 98 feet (30 meters) on the day the picture was taken, Bister confirmed to SPACE.com .
This type anomaly has not been observed on the Opportunity rover as it wheels around Endurance Crater on the other side of Mars.
-- Leonard David
I think they are completely wrong in that article. The dynamic braking problem is not the one causing for the wheel to drag through the soil.
The braking problem is related to the relay that locks the wheels during driving so the wheels won't turn or steer (not to be confused with rotating). They identified the issue as a faulty sensor on the relay, and are now ignoring it, so the problem is somewhat solved at this point.
The wheel dragging is a completely different problem. It's the wheel motor that rotates the wheel, and it is causing excessive current draw. The motor or the gears are starting to wear out and so they are dragging the wheel on purpose to spare the motor (or gears) as much as they can.
Correct me if I'm wrong, but isn't this all a bit of recycled 'news'? ( Except the 30 meters bit, didn't know that ). I hope the title should not be taken seriously... It has been three days since Spirit moved. Long weekend this time, or 'broken down'?
I think they're still moving:

How do you determine that Spirit is at the location marked 316? That seems pretty far away from the ridge and I don't think Spirit has got that far off its path.
I believe we are still close to the centerline on the ridge continuing straight towards Husband Hill...
I found spirit's location in a nav cam image fron sol 310

Boy, I think you're off here. That light patch that shows up in the SOL 316 picture is very close up. Were it the same one in the distant color pan shot, it would be huge and those rocks you point out wouldn't even be seen they're so small. My guess is that you're right up through around 305 or 306 but then the rover starts climbing to the East. I doubt you can even see the area it's in right now from that distant pan. But who knows? I could be very wrong. It's why we desperately need an overhead route map drawn by the engineers driving the rover.
That makes much more sense. In this pancam shot from Sol 315, the two "notches" on the hill ahead are clearly visible and if Spirit had gone north, the perspective would've been much different.
JPL included headings in the navcam panorama for sol 313 so I did some triangulation.
This is what I came up with
http://s04.imagehost.org/view.php?image=/0754/spirit_313c.jpg
Update: Spirit travel map until Sol 313
Hmmmm... no drive again today, perhaps those wheel problems have become a bit more serious.
Anyone have any inside info on what Spirit is upto?
A week off for Spirit, should have the battery fully charged. How about a 100 meter drive.?
There's very little new data coming down too. Just the usual images of the pancam calibration target and the Sun.
I am still hoping for a pan from in between the hills, even if it is a Navcam pan, although I would prefer a Pancam pan. It is too bad that while the rover is parked they don't take advantage of such opportunities for a good color pan. This could be achieved through tri-color imaging and perhaps 2x2 or even 4x4 binning in 2 of the colors, or perhaps all three with a full resolution clear-filter data set. I realize this would be of little scientific use, but it would be great for future coffee table books.
For the last 5 days MER site has posted 58 shots of the sundial and 18 of the sun. Are there images of something interesting to go with these waiting to transmitted?

I get the impression that they may be starting to climb slightly.
Look at the way the ground is torn up on the right and all the short turns on the left. I bet Spirit got a rock stuck in front of one of its wheels and was pushing it along. The extra tracks on the left must be the first few attempts to manuever around it.
http://qt.exploratorium.edu/mars/spirit/rear_hazcam/2004-12-01/2R155227908EFF9500P1313R0M1.JPG
Alan, per your twin pictures you posted today - You seem right on with the black and white shot but it's my opinion you're way off the mark with the positioning in the color shot. I'm absolutely certain that Spirit is not taking this long trek to the North as you propose but is in the hollow out of sight to the east of where you show the position on Sol 310. The progression you're showing is taking them completely away from Husband Hill, their stated target. Look back again at the overhead shots. There's this large open expanse between the knob they originally drove to the top of and Husband Hill to the east. Most here seem to believe that's direction they're heading, not off to North as you keep posting. That color shot was taken from a long ways off while Spirit was approaching from the west and the features you seem to be using to pinpoint locations by comparing them with small rocks and dips in recent photos wouldn't even have been visible then.
Then again I could be just as off in my assessment. I Welcome the brainstorming none the less.
Update:
Spirit completed acquiring a large "Thanksgiving" Pancam panorama on Sol 324 and is continuing the travel towards Husband Hill. Spirit has just about crossed the flat saddle area between Husband Hill and West Spur and will be blimbing steeper slopes soon.
Sol 325 - Spirit continued driving Eastward across the flat saddle area between the West Spur of the Columbia Hills to where the terrain slopes back upwards towards Husband Hill. She successfully completed ~35 meters of 5-wheel driving bringing the total mission travel distance to 3.82 km
Future Plans
Next week Spirit will continue to drive further up the hills, and will be looking for outcrops along the way. Two possible routes are still being considered - a route that would head directly towards the top of husband hill, and a route that allows exploring of a steep walled canyon on the North side of Husband hill.
Great! This might be the "pan between the hills" I wanted.
Azstrummer, where do you think that pass in the distance is? Do you think it is the spot on my color image where I have been locating Spirit? The pass in the distance certainly looks like the pass between Clark Hill and Husband Hill to me. Take a look at it in this color panorama
http://www.whatonmars.com/womiod/11-2004/wom_iod041129a_.jpg
and compare it to the one here
http://marsrovers.jpl.nasa.gov/gallery/press/spirit/20040528a/Sol131A_Hills_P2434_L256-A143R1_br2.jpg
Alan, I understand there are major similarities but you have to remember, that second image you keep showing was taken from at least a half mile away and you're comparing features from a picture where you're right next to rocks and hollows. Also that second picture was taken almost due west of the West Spur which would mean that the hollow between the spur and Husband Hill that Spirit is currently in would not be able to be seen from that perspective. Go back and look at the shots from the orbiters. The hollow between the spur and Husband is clearly visible. There simply are no other reference pictures to this area from the ground prior to Spirit's recent travels.
That pass in the distance that you refer to in the recent shots is merely an opening between some sub-hills blocking the main ones. Remember that Spirit went down into a hollow and the foreground features would surely block out the ones in the rear. My guess is that this is all going to become apparent in the next few days as Spirit climbs over these small ridges and the mass of Husband Hill looms ahead.
You don't do much hiking I take it. lol
No, boy scouts was a long time ago. We obviously have a different interpretation of what point on the overhead shots corrsponds to the end of the ridge Spirit was on and in what Spirit was direction was looking when it took the shot on 149. I got 110 degrees from the route map that was posted earlier. In the panorama from 313 I can see over the end of slope in that direction, so I'm assuming that its current position should be visible from there. It should become clear where Spirit is pretty soon. I expect it to turn to the right and head up the north edge of that ridge to the right of its current position. Of course that is pure speculton on my part.
I've been doing a great deal of looking at the pictures in 3D - been building my own anaglyphs. It's truly amazing when you do that how a seemingly flat terrain becomes this series of very extreme up and down ridges that the rover is climbing over. Just a few weeks ago they went from a view of very rough terrain with Husband Hill looming huge in the background down into this valley between the spur and the base of the hill and suddenly you couldn't see that huge foreboding hill anymore in any of the pans. I think that's where we kinda lost all reference with the rover down low enough that even the small foothills in the foreground were blocking out the massive rises behind them. If my theory's right then the next day's climb should get them back the big picture again. Who knows though. I've been wrong many times in this mission trying to decipher the trickle of stuff coming from JPL at times.
So much for my predicted right turn.

object dimension: 43.0 cm
Site 99
object distance: 4.296 m, one-pixel error: 0.009 m
object dimension: 42.5 cm
I used the large rock in this view for

and thi
Spirit Update:
Spirit is currently in a challenging sandy terrain attempting to brush and RAT a rock named
Wishstone over the weekend. The slippage experienced during a Sol 332 drive was more than
90% (1 meter traveled vs. 9 meters sequenced).
The right front wheel is drawing normal current again--it is no longer experiencing larger than
normal current draw. The theory is that the rest period at West Spur allowed the lubrication
to redistribute. They probably pushed Spirit too hard earlier
After working with Wishstone, Spirit will then attempt to reach a ridge called Larry's Lookout
to look for interesting science targets.
Some interesting maps follow. This may be the most accurate map yet (the one posted at JPL site
had several inconsistencies). Also a view of looking back and a view of Wishstone. Sorry about the
width of the image, but I think it's worth panning left to right to see the full path...

Yes I've seen it. I think they have their positions too far up the hill, in the last few posts I've been picking it apart. It's not the best image for showing the planned route. This one shows it better, at least its what I think they are trying to show.

No - we're still a long way from the summit - it's a common optical illusion that the summit is closer than you think> There's a good half km to the summit from here
If you look at Alans map two posts up - we're about where the 1 of 410 is written

But Spirit is headed in opposite direction of the visible area, it is en route to summit 02 or even pass it and start descending towards the previous Lookout Point:

According to the latest post by ObsessedWithWorlds in the Directors Update forum:
"On Spirit it’s sol 448 and she’s sitting about 300 meters below the summit of Husband Hill."
I wonder if the true summit is seen on the thin strip of distant ridge just visable over the left shoulder of the "summit" in the previous image.
OK, I admit... I was too optimistic! I was based on the apparent alignment of the "summit" with distant hills, but looking also other images, is claer that real horizon (extreme right of following mosaic) still well below this summit, so a big way ahead!

Ther's quite a detailed account of the whole affair in lunar geologist Donald Wilhelms' book "To A Rocky Moon". Wilhelms is still tearing his hair out over the whole affair because he regards the samples from near or at the rim of Cone Crater as the most important ones for understanding lunar history as a whole that would have been obtained from any of the Apollo landings -- and they only obtained a few ounces from their site within just a dozen meters or so of the rim, since they didn't know they were there. As he points out, though, that wasn't their fault; the terrain was simply too hummocky and misleading as seen from ground level. A range finder to the LM (which was seriously considered once) would have solved the problem.
Quite a few route maps (to Sol 450) have been posted by NASA here:

I follwed the link recommended by jamescanvin and noted one patch that have caught my attention before, so I try asking here since you seem to be knowledgable people here, so here goes:
What might that that dark spot in the inner basin be, volcanic ash?
Having nothing to do one day, I thought I'd play with a Spirit route map. So first I took the nice set of Pan Camera pics from Sol 498 looking ouit across the plains, and made a mini-panorama of them:
Cool! You're probably right on Missoula & Bonneville. Nice work. Nice to see.

I tried to re-identify your way-points in the original panorama, indicating possible location of Spirit lander. Am I right?
Dilo - Lahontan is the bright spot further to the right from yours - same distance below the horizon, but to the right of your lander spot. Then, if I am roughly correct, Missoula is the fuzzy slightly bright patch just to the right of that and a bit further away. As for Bonneville, I'm really not sure yet. I think I may have shown it too far away.
In fact, a very quick look again suggests to me that my Missoula is really Bonneville. What I said was Bonneville, and a similar dark spot south if it look like two features about twice as far away. The rugged hills on the horizon are also uncertain but might be on or near the rim of Gusev itself. Anyway this is a work in progress, and I welcome anyone else's insights.
Phil
I'll jump in. I found Bonneville and Missoula in the color panorama from 497. Missoula is the easier to identify, it has a light "smile" on one side. Lahontan is the light area between and in front of Bonnevile and Missoula. I think the heatshield and backshell are visible too.

I'd like to take a look at the original images for Phil's pan. What sol is it from?
Hello, For a small three dimensional exhibit on Spirits journey across gusev, we have come to a number of stumbling points. I am hoping that someone on this forum can fill in the blanks.
In the famous Sol 454 mosaic, Spirit is looking in a NorthEast direction. The hill immediately to the left is identified as Clark Hill. Does the hill in the distance have a name?
For accuracy in our model, we have been looking for the dimensions of the landmarks Spirit has been exploring. We found out that Methuselah is 3 ft. long. Has there been measure of how high it is. The same information for Jibsheet and LL are needed. We know that Husband Hill is 60 ft. above the plain. Are there measurements for Clark Hill and the mystery peak in the distance. Thank you for any information. Laura Zelasnic
Hi - the hill to the north - the bigger one - is really two hills one behind the other. If you look closely, especially in the beautiful color pan by ( I think) Deeman on this forum, the distinction between them is easy to see in terms of texture. The nearer one is Clark Hill, and it's scattered with dark rocks. Behind it is Chawla hill, further away and smoother in texture (maybe only looking smoother because it's further away).
The hill to the right in that pan, on the more distant horizon, is part of the rim of an old eroded crater called Thira. The crater name is sometimes written Thyra. I have myself made this mistake, but I just checked with the USGS and Thira is correct. I don't have a height for it, but higher than Clark Hill.
I don't have sizes for the foreground features. I think a question directed to Ron Li at li.282@osu.edu (who does mapping for the team) might get that information.
Please post a photo of your exhibit when it's done, if you can!

Hi, Tman... I can't find it either! This is the image number for the left-most frame, if that helps... does the time information help you find it? I thought I might have picked up some frames from an adjacent sol but now I can't identify them.

Sweet! The code was helpful - it's from sol 497. On Exploratorium there are 159 files, but therefrom still nothing in the JPL raw pics: http://marsrovers.jpl.nasa.gov/gallery/all/spirit_p497.html I guess JPL won't share any longer the coming Pancam pan from eastern Larry.
Here a color pan from the sol 497 shots:

The image editing to enhance Bonneville's visibility could be probably better, but my knowledge therefor isn't that great thing.
By the way, Alan's line item specification should be right.
I want to thank the members of this list for your assistance in identifying features and Spirit's traverse across Columbia Hills. This has helped our project immeasurably. Probably you will be hearing from me again as we focus our model. Thanks, again. Laura Zelasnic
Tman's Sol 497 panorama (I *still* can't see that darn Bonneville) just adds to my conviction that there's a sorting process going on with regard to small impacts. Consider the sort of view we got from Apollos when the guys drove (or walked!) up hills - rounded, yes, but always cratered - and at all scales. I just don't see the smaller chaps at all on Spirit's landscape, and even from Opportunity the craters we've seen on the ground have been few and far between. Certainly, the bigger chaps are there - but the 10 metre and below boys just vanish in the mist...
...makes me wonder what the historical (in geological terms) changes in the Martian atmosphere meant in terms of things actually hitting the ground.
Maybe these new images including the specification of the direction could help (the pan isn't quite exact):

maybe interesting to see this pseudo-vertical projection from the "true summit" (Sol619), with identificable traces/maneuvers from previous Sols. Thanks again Michael, for MMB!!!!
Is this Steve's first mention of the Ultreya Abyss? I wonder if it is a direct or in indirect result of his conversation with Doug?
"If we can get down onto the lower part of the ridge, we'll eventually hang a hard right turn and head south, toward Home Plate, crossing some interesting-looking terraces and passing just to the east of a dark patch of sand as we do."
Doug, at one time in another thread you posted a 3-D topographical map of Husband Hill. Alas I cannot find it. I thought it might be a useful instrument to follow the planned path for Spirit downhill, as outline in Squyre's latest update. Do you still have access to it and if so, can you post it again?
Thanks
Here's my guess from http://marsrovers.jpl.nasa.gov/gallery/press/spirit/20040506a/09-AK-02-Columbia-Hills-Flyover-B101R1.jpg which I rotated so north is up:
Hi all,
Now that Spirit will start moving again down to the Inner Basin, I was thinking on how to plot a fairly precise route map, without the need to depend on the traverse maps from the MER webpage.
I'm afraid that Dilo's superb work on Oppy's route map wouldn't be applicable here; it needs a quite good terrain modeling to produce precise results.
Another option would be with the use of polar projections and trying to match the headings to medium/far range features on the route map and on the projection. But this method has an error quite high if compared to the expected drives in the 5-30m range.
A third one would be to estimate the rover movement (heading/distance) by pinpointing similar features on before-drive and after-drive navcam/pancam images. But again, this method has a drawback: it accumulates the errors drive after drive.
At the end, I don't know which is the best method -- or let's say the "less worst" -- to plot the route map.
Comments are welcome.
I would suggest that the most likely method to produce reasonable results would be a combination.
Dilo's method could produce reasonable results with a simple correction for the mean slope of each area. Areas of more complex morphology would be troublesome but Spirit will tend to avoid them anyway. The second option - polar projections and headings to medium-long range features is good but accumulates errors, as Tesheiner says. The third option is more like 'dead reckoning', estimating travel distance and direction, and accumulates errors as well.
All three methods will give a rough path. But at intervals of - let's say - 200 m the position could be checked more carefully with azimuths to major features in the surrounding landscape. That can help get the route back on course. If it has drifted off by 25 m, a corrected map can be made with the correction distributed over the whole journey since the last check.
In effect this is what the MER team will be doing, with Ron Li's bundle adjustment work used to correct Larry Crumpler's day by day mapping. We saw evidence of this in a Spirit map release earlier where the two positions were both plotted.
I eagerly await any effort to do this! Incidentally, even when this glorious mission ends there will be lots of good work to do retrospectively with this kind of approach. Imagine a Dilo-style map of the interior of Endurance, using a rough shape model to correct for tilt!
Phil
I think combination of the three methods + distant features azimuth localization could give good results...
There is a fourth "absolute" method based on the massive use of parallax calculation in order to obtain a true 3D terrain model; however, if done manually, it would be extremely time-consuming
About first method, note that there is a useful shortcut in using the locally-planar projection (or even its approximate version produced with MMB - see my last post in this thread): you can use rover tracks as a gauge for the best local terrain approximation... if done through a rendering software like PovRay, this could give local terrain slope/orientation!
If I will have enough time, I will make a try... meanwhile, someone else can do the same using MMB panoramas.
PS: Phil, it seems you deeply knows the Mer team members/jobs...

I was ASTONISHED by the Sol 659 drive - you can not see two sets of tracks, they must have backed up straight over the orig ones...astonishing driving
Doug
Seems like they have taken a leaf out of dilo's book in "Route mapping for MERs" with their polar projection type bit.
Looks like we ought to be making a sharp turn to the west sometime soon. That was a quick descent.
Update to 670
There was no update on Spirit traverse maps at the official MER webpage since sol 659 drive, and I wouldn't expect any until after Thanksgiving holidays.
So here is what I've been tracking until sol 671. Data until sol 651 have been adjusted to the official map while further positions up to sol 659 fits quite well with the traverse map.
Tesheiner's map looks good to me, though I have not yet had a chance to compare it with my day to day notes.
Phil
The nearest tracks from the sol 666 drive are 20 meters from Spirit's current position, so the sol 671 position should be about 20 meters to the SSW, near the edge of the dark patch.
New SOL 668 traverse maps are up:

Dunes (drifts, ripples etc.) might be interesting if there were no other good targets around, but this is a geological wonderland rick in outcrops of rock of different types. The stuff of dunes could have come from anywhere, but bedrock is in place where it formed, full of clues about its depositional environment. It's going to be bedrock all, or most of, the time...

This image shows the route that NASA's Mars Exploration Rover Spirit has driven inside Gusev Crater from its first Martian day (sol 1) to its 680th sol (Dec. 1, 2005), more than a complete Martian year. The underlying image (previously released as PIA07849) is a mosaic of images from the Mars Orbiter Camera on NASA's Mars Global Surveyor orbiter. The scale bar at lower left is 500 meters (0.31 mile). As of sol 680, Spirit had driven a total of 5,495 meters (3.41 miles).
One more ridge and we finally get a good view of Ultreya?

To reach McCool Hill, Spirit has to take the route between Home Plate and Alleghenny Ridge.
Could be, IF the intention was to go direct to McCool Hill.
But afaik the near-term objective (sol 750?) is to reach and study Home Plate.
Imho, this last drive SE was just a way to avoid going directly over the dunes. A left turn to reach harder ground.
How about Rectangle Ridge, for the formation's overhead appearance?

Double quoting Doug...
I've sent a polite email to Dr Li ( he of MER Mapping fame, and the head of the dept. that produced those most recent, amazing maps ) and asked if he might be able to release an elevation map or DEM so that I could do some perspective views and animations of the area. If we're lucky, I might be able to do something like the old perspective views I did - http://www.unmannedspaceflight.com/doug_images/elev_1.jpg - but much much MUCH better
Doug
Somewhat close, it is a bi-dimensional map. I am copying it the updated Jan 5 Spirit route map with altitude reference.
Southwest is of the lowest altitude and the Southeast is of the highest altitude.
I think that Home Plate is still out of range in that map, still further south.
Rodolfo
Alan, is this image exaggerated version?
Yes, it's a 2x vertical exaggeration. It makes it easier to see the hills in front of homeplate.
Alan, could you post the non-processed image (without route marks)?
With or without the verticle exaggeration?
Just without exaggeration.
Thanks!
The contours on that OSU route map seem to be suggesting block faulting on some of the hills! That's the first time we have seen anything like that on one of the maps, iirc.
No - there's a 'ripping' to the stereo interpolation there - that's not real features. - some go straight thru El Dorado, and we KNOW what that's like.
Doug
Spirit drove to the next dune
alan - love your maps. But I think the black numbers on the dark ground could be made better..
I tried making yellow numbers and I think it shows up much better
Only a suggestion to improve your wonderfull maps
dot/alan, I love too these maps , we should continue to update them!
[/quote]
Here's a preview of something I'm working on for a book proposal after my current one goes in next year.
I am making a set of maps of the whole Spirit route at a standard scale, showing placenames as well as sols. This map is a 500 m square - the whole route up to Home Plate requires 9 maps like this with a slight overlap. For areas which need more detail, such as West Spur, additional high resolution maps will be created, probably by reprojecting surface panoramas as I did with Eagle and Anatolia recently. (They were also experiments for the same purpose, basically to estimate how many pages will be needed for each rover).
The background is poor, but it will be replaced with an MRO image (or a better version of this MOC jpeg) later

Route map, up to sol 719.

Tesh, I'm beginning to worry that we'll not spend much time at Home Plate...
I'm speculating that it will take at least (and that's moving fast) another 7 to 10 days to get to Home Plate - and with little time for doing much probing, another 8 to 10 days to get to a North facing slope. Do you (or anyone) see a route fast enough to get us to Home Plate and to safe wintering ground, in time?
In the link below, I've used a piece of your Route Map to illustrate daily drives - for perhaps 14 days+... and you can see where we may run rather short of time.
http://anyold.com/mars/Route_Map_Sol719_speculation.jpg
I'm beginning to wonder if Home Plate will be left for the springtime...
Well - I ~tried~ to remove the attachment, Tesh - it got there without showing up in the preview - and after the system said that it was too big to add. (That's why I posted the link to an altered smaller image.)
It is ~definitely~ time for bed...
Your proposed path seems reasonable; there are other ones on the "Going to Homeplate" thread and we may be really speaking of some additional 10 driving days until reaching Home Plate.
Little time for science? Dunno.
I can only refer to what was already said by S.S (see http://www.unmannedspaceflight.com/index.php?showtopic=1850&view=findpost&p=31866): Home Plate by sol 750 and McCool Hill by sol 800. They are the experts, and for the time being Spirit seems to be on schedule.
Can't see us being in that much of a hurry. You have to remember that this is Mars and with the year being twice as long so are the seasons (though the eccrenticity of the orbit complicates it a bit, southern summers being a bit shorter). We're still in the beginning of autumn.
Looking at helvick's power chart the maximum solar input now is about the same as it was at the end of the primary mission -- and that was when Spirit started her long treck to the hills.
http://www.unmannedspaceflight.com/index.php?showtopic=1204&st=0#
Steve also said that the schedule was to be at HP around sol 750 and getting to the slopes on sol 800. So we are well ahead of that. I'm betting Spirit will spend a good month on the Home plate.
I missed some earlier responses to one of my comments, and am now catching up. In the preview this reply looks terribly large. Would people prefer me to break up such a reply into separate pieces?
Tom, big replys are OK with me; it takes as much time to read three small messages as one large message.
I've had training in gridding software, and the offsets look like common glitches, which should have been corrected by the operator before going to a final map. What happens is that there are anomalous values in the location and elevation data input values, the software doesn't know how to handle them and it makes certain pre-programmed assumptions on how to handle this and sometimes comes up with these odd jumps.
"Gridding software" is a computer program that takes a dataset of x, y and z values (length, width and elevation) and by sophisticated mathmatical interpolation, creates a grid or mesh. The viewing part of the software can take this grid dataset, view it from any angle, rotate it, give it vertical exaggeration, create topographic contour lines and overlay it onto a photographic image.
Pathfinder/Sojourner was the "proof of concept" mission for the mobile lander idea, but our Rovers are the first time we have had long-term mobile robots on Mars and, given that this was the initial foray, the mission has been a resounding (and astounding) success.
I'm close to retirement. I may sell my dogs, move and live in a packing crate, and do volunteer work...
--Bill
MOLA is far too low in resolution to help make a topo map like the one discussed here - two orders of magnitude too low, probably. It can only just resolve the hills, but not show significant detail. The contour map is based on stereo analysis of MOC images - if you try to overlay one MOC on another in a program like Photoshop you can easily see differences caused by the relief and slightly different viewing directions. But in areas where there are few obvious control points - Eldorado being a good example - the stereo matching and bundle adjustment software will give poor results. Also, there have been serious issues in trying to create DEMs from MOC images because it's a scanning camera with an ever-changing viewpoint, not a framing camera which takes an image in a moment.
Phil
I think MaxSt is right, Rodolfo.
The arrow is pointing behind the hill, exactly to the dune where Spirit is working now.
Nice speculation !
If I were a MER geologist, I would go :
- first taking a panoramic view a little above Home Plate on its border ridge on its east side (right hand side of your picture) ;
- then fully explore Home Plate by crossing it towards its west end (left hand side of your picture) where are some other "white" deposits and verify its stratigraphy ;
- then go to Pitcher'Mound to verify if it is (or not) a cinder cone and/or a source of pyroclastic flows ;
- and finally head south/southwest towards Promised Land !

The most recent drive was a very good one imho - complex, but good progress made. Perhaps they intend to head for the dip between the local summits in this line of humps leading toward HP
Doug
We're out of the sand now (nobody has made a navcam panorama yet, hello?). Seems like Spirit traced her http://qt.exploratorium.edu/mars/spirit/navcam/2006-01-18/2N190911409EFFAMJ5P0695R0M1.JPG, and then made a short move up the slope. http://marsrovers.jpl.nasa.gov/mission/status.html confirms that Spirit was stopped twice by automatics because of 80%+ slippage around this dune. Sounds like they were using the same visual odometry as for Oppy?
Spirit could move up to the ridge, as Doug suggests (I initially thought they would just drive straight over it from El dorado, instead of going southeast). Other option would be continue roughly southwards by skirting on this slope.
I think that's a good example of "one step backwards and two steps forward".
About the next steps, I'm still of the opinion that Spirit will follow this slope southwards. It seems too early to climb to the top of the ridge.
I am thinking that the solution for Spirit to overcome the bump, is by taking the same strategy as Oppy did when it got out of Eagle Crater, by transversing on diagonal line (very soft slope, perhaps less than 5 degree) on the nearby hill.
It is impossible to jump the bump in front unless MER has upgraded 6 Maxon electrical motors in order to race up to 15 km/h.
Let see it what is the bet of rovers.
Rodolfo
This image is the foreground of Dilo's excellent pan, very simply reprojected (using nothing more than Photoshop's perspective tool) to show the route in something a little bit more like map geometry.

I have been wanting to do a Spirit route map on an MOC anaglyph of the hills for a long time, but I never seem to get around to it. Alan's easy to follow images encouraged me to do this oblique view instead.
I took the amazing JPL long baseline anaglyph of the basin and copied Alan's Sol markers to it. Size was reduced by 50% and then cropped, and compressed a little to get below the 1 MB limit. It was a lot nicer at full size, but the sol numbers are a bit too small at this size. Maybe I should increase the size and the compression. ?
I know all here are not big fans of anaglyphs, but I really find this to be a useful way to visualize the route. +/- comments are welcomed.

RE: Spirit Route map
Googled Mitcheltree Ridge, came up with this:
http://www.nasawatch.com/archives/2006/01/bob_mitcheltree.html
That is very sad, but what a wonderful lasting tribute to have that ridge on Mars named after him. I never heard his name connected to the EDL, but I can understand he was a major figure in the work. He certainly lived to experience what must have been a tremendous satisfation when the rovers landed so perfectly.
RIP
Actually - this is 100% true and accurate - if you put the landing site onto the place where I last gave a talk to the BAA ( English Heritage Lecture Theatre near the Apple store ) - the other end, if you rotate the route - lands EXACTLY on the new venue the BAA are using at Kings College London.
Freaky

Thanks for the kind and helpful comments regarding my first tentative step into the scary world of route mapping. As I attempted to guess a position for sol 732 tonight, I discovered just how tricky it can be. For the time being, I'll just follow in the footsteps of the masters, transcribing their work, as I hopefully learn some of the tricks of the trade. I see alan has already positioned sol 732, and I'll try to add that soon. If I had used my best guess tonight I would have been way off the mark.
mars loon: Even if you hadn't made so many helpful comments regarding my presentation, you (and anyone else) are welcome to use anything I may post here. It's public domain. There is one thing missing in my images, which I hope to correct in the future. That is the label in the bottom right corner, ascribing credit to NASA/JPL/etc. I'm posting a new version of the previous one tonight. The first suffered greatly from the 50% size reduction. This one is at full size, but with some jpeg compression to get it below 1 MB. The sol numbers should be easier to read now. This should look better, even with cardboard and film glasses.
I almost added some place names, especially after noticing that they really did name a feature in memory of Robert Mitcheltree and his many contributions to space exploration, as was mentioned a while back. I had to Google a bit deeper to find an "official" mention. It's here: http://www.nasa.gov/centers/langley/news/researchernews/memoriam_micheltree.html
I can't add much to what others have already said regarding his tragic loss to humanity, but I surely would have liked to have known this guy. Now, we know the person we should salute, as we vicariously rove past this intriguing ridge, with the help of a device he helped to deliver to this location.
