Where is she? http://www.greuti.ch/spirit/pan-spirit-sol311c.jpg
Where would you put Spirit in that picture?
Another neat picture to show Spirits recent work area

Along with this flyby of the whole area!

I have not seen a wide enough view yet to do much more than throw a dart.
What the heck, here is where the dart landed.
http://s05.imagehost.org/view.php?image=/1205/Dart315.jpg
It's not easy to say. This spiky large rock to the right next to Alan dart should be this one: http://qt.exploratorium.edu/mars/spirit/navcam/2005-06-15/2N172089761EFFAB70P0715L0M1.JPG
My guess Alan hit a field to the right of the Bull's Eye.
Dot, very nice video clip. In such a manner the first of Rover's track to my knowledge.

Et per si muove...
Yup - another good drive today - that's three days of successive driving
Ust - what sol was your first image taken on? 300ish?
Doug
I thought that in today's drive Spirit would pass by the left side of that piramid shaped rock. That way looks less bumpy then by the right side.
Doug, the 1st image on Ustrax picture seems to be the one from the first post in this thread (Tman's picture from Sol 311).
Tesheiner
Just found another one...Sol 256...
Up we go!
http://img.photobucket.com/albums/v352/ustrax/loc3.jpg
Yeap Tesheiner...It is the same image, sol 311...
Thank You.
That makes sense, drive south along along an easy route. Then attack the summit from the south, keeping the solar panels tilted toward the sun just in case the dust storms get bad.
Prediction: wider view from the navcam tomorrow.
Mars is approaching the southern summer, the sun should be moving into the southern sky.
Since Spirit is 14 degrees south, the sun is only in the southern sky for a short time around the solstice. Did we just pass that or is it still coming up? No matter... the sun should be very high in the sky.
The southern solstice is August 17. By the way, Mars perihelion was two days ago.
Wider view from current location

when they finish downloading this it should be 9x2 in color
nice!
From rightmost two images, I identified the main horizon features (processed in order to enhance far details, angles measured from South direction, satellite map is upside-down):

Thank you Dilo for your dedicated work, also you Alan.
Arrived here from Exploratorium and even after a year I still browse those images amazed over the fact of being able to get almost daily updates, this time I happened upon something I was unable to identify.

Its also seen on the lower left on Alans stiched-together image.
To me it looks like a small shallow depression of small gravel or perhaps the kind of salts already found elsewhere in these hills.
We might get to read about it is its investigated, but if its not, anyone interested giving their views or tell me im wrong and that it's just one uninteresting patch.
Beautiful mosaics, alan, you are really on a roll!
Nice progress today

jvandriel
alan, great to see your route maps back, but I believe Spirit is on its 520 SOL
New traverse maps:

Nice Maps!
Too bad we don't see daily reports on average slippage. Then we could have some fun correlating that with the current slope and ground texture.
I think my brains frazzled, I couldnt spot yestersols drive distance, and I cant for the life of me line up nav/pan features with S311 imagery at all
Doug
My brain isn't frazzled yet (could still come) But I also dont know where I could Spirit place...
It's heavy because I also dont know where the horizon line from the sol311 pan could run in the bird's eye view maps.
Are we already outside the range of vision (for the sol 311 position)? http://qt.exploratorium.edu/mars/spirit/rear_hazcam/2005-06-24/2R172890362EFFAC00P1312R0M1.JPG
Hereabout
http://s05.imagehost.org/view.php?image=/1227/hushillb524.jpg
pretty close to the top of the image from 311, I'm not going to post that one, wouldn't want ustrax to celebrate too early
Have a look at the latest traverse maps for Spirit (http://marsrovers.jpl.nasa.gov/mission/tm-spirit/index.html). On the first, most detailed one, Spirit is already past the trough, on the second, she's not yet there. Looks like the position marked on the second map as sol524 is in fact for sol 523
No, general... they are different troughs. I know it's not obvious, but if you overlay the maps in Photoshop (etc.) or carefully compare the small dark circular poatches you will see it.

Traverse map update:
http://marsrovers.jpl.nasa.gov/mission/tm-spirit/images/MERA_A530_travstat_3_br2.jpg
Another traverse map at :
http://marsrovers.jpl.nasa.gov/spotlight/spirit/20050713/20050713_sol536_MOC.jpg
...and this one has contours.
Interestingly, they only seem to have climbed 10m or so between Methuselah and Independence, and they have around 30m of additional elevation to gain between here and the summit[s].
I've taken those contours - generated an elevation map - and came up with these...

Doug
In looking at those elevation maps, I got the feeling I was playing Railroad Tycoon 3 again, trying to find the best way to the top without getting a track grade in the red
Doug, what's the vertical scale exaggeration in your pictures?
Nice!
Hugs it well?
Looks cracking good! Gives a good feeling about the shape of the Hill!
I just mull over how you've generated it. Was it necessary to get the contours for it? Are more pictures than the map behind it?
One point of criticism, it seems (to me) not "completely" fit all-over.
The calibre and skill level of the people on this forum never ceases to amaze!! Way to go Doug!!

Can anyone identify Spirit's Sol 549 location on these (magnificent) elevation maps posted by Doug? I am having a difficult time estimating distance to summit based on 549 pictures. The summit seems very, very close (10 - 15 meters?), but the distances also seem very deceptive.
about where the trough crosses the last contour
.
Assuming trafficability on the top of the hill is decent, which I expect it will be, they should drive to the south roll-off and take two panoramas looking south with some tens of meters baseline for long-range stereoscopic analysis. One could be single-filter black and white to save bits. They should then to to the east-northeast flank and do the same looking down across the big bowl to the east of the smaller crater like bowl overlooked by Larry's overlook and then do the same to the east-south-east.
Such multispectral and long-base-line monochrome stereo mosaics would be the single most valuable imaging product of the entire Spirit mission, and would be of crucial value in decyphering the complex and confusing stratigraphy and geology of the hills.
New traverse maps!
http://marsrovers.jpl.nasa.gov/mission/tm-spirit/index.html
Are those strikes and dips they've added to the traverse map? If so, we're looking at strikes of 180-190 degrees south and dips of 10 to 30 degrees west, which is different from what we saw at Methuselah and Larry's Lookout.
What is "Li's sol564 loc" ?
http://marsrovers.jpl.nasa.gov/mission/tm-spirit/images/MERA_A565_3_br2.jpg
No idea ....
In the broader map the same spot is identified as "Sol 564 OSU position"
http://marsrovers.jpl.nasa.gov/mission/tm-spirit/images/MERA_A565_2.jpg
IIRC, Li is a professor and his lab is doing independent image analysis for JPL.
(I remember something like this was mentioned before in this forum, if you search for it you 'll find it.)
Looks like the calculations by two science teams result in different locations for Spirit.
http://shoreline.eng.ohio-state.edu/
They are probably using the OSU work as a check against their own position estimates. That there is a substantial difference has apparently become noteworthy enough to mark it on the traverse map.
The position of the two summits has also changed considerably compared to the Sol558 map
In the attached image I have marked with red circles the previous summit locations.
I wonder how much the route maps will change once we have a HiRISE image of the place
Doug
New Spirit route map out today at JPL (Aug 15)...
Plus, this perspective:
http://marsrovers.jpl.nasa.gov/mission/tm-spirit/images/sol_572_in_sol149Pan.jpg
I'm pondering the discrepancy between Ron Li's position for the rover and the positions shown on the JPL route maps. The problem is the difficulty of getting an unambiguous feature match between the two very different sets of images, surface and orbital. The JPL maps are basically done by a sort of 'dead reckoning' approach which can be put off the mark by wheel slipping etc. They need to be corrected from time to time by the OSU work.
Well, this forum would be no fun if we couldn't occasionally take a chance on a wild unsupportable statement... so I have somehow drifted to the conclusion that Ron Li is right, or almost right. I might be a short distance above (north of) his position. So I predict that the JPL map will be redrawn shortly to correct for this.
And what about that new view? Amazing! This armchair Mars exploration is way better than real life.
Phil
There is also a short "surprize" update from Steve Squyres...
"Just a quick one today. We had a great drive with Spirit on Sol 576, and we're now approaching the summit region of Husband Hill. What we've learned from the latest images is that the thing we've been calling Summit 1 -- which we had thought from orbital images was the lower of the two summits -- is actually the higher one. So we're bound for Summit 1 now, instead of Summit 2. Near as we can tell, we're only about six vertical meters below it, and the path from here to there does not seem to present any impassable barriers. "
http://athena.cornell.edu/news/mubss/
Latest traverse map:
http://marsrovers.jpl.nasa.gov/mission/tm-spirit/images/MERA_A578_3.jpg
Summit 2 seems to be canceled.
IMHO we have not yet reached the summit.
But this discussion should be more appropriated http://www.unmannedspaceflight.com/index.php?showtopic=1294&view=findpost&p=17889.
With the help of Malgar and starting from digital terrain models from USGS, I made some PovRay simulations in order to verify rover position.
Here a comparison between Sol582 panorama portions (from Tman) and correspondent DTM simulation:
oops, wrong thread!
damn dilo, you're getting good. I can't wait to see when you drape the images over the models......
thanks for all the effort you put in it... it is very much appreciated.
