Now that we're approaching the Homeplate basin, I've noticed something odd. From the color images of the Inner Basin taken from atop Husband Hill or from Comanche, I see many large dark boulders and a few large light-toned boulders the size of the Rover or larger on Mitcheltree Ridge. But now that Spirit is climbing that ridge I haven't seen any large boulders. I had assumed that this was a blurring phenomenon, but blurring tends to bleed over from the light areas (sand) into the dark spots (rocks) and not vice versa, so the dark rocks should be made less visible.
Any thoughts? Not a big deal, this just bugs me...

Full Version: Going To Homeplate...
Another move (sol 739). 
Pitcher's Mound is on sight again, and I think Home Plate too.

Now, Spirit at the top of Mitcheltree Ridge, I have noticed that zone is more windy. See the formation of tail of sand back of every stones. The wind has a prominent direction on that, seems to be toward West. The other interesting thing, on the floor of Inner Basin, we see fewer boulders or stones but the stones density increases on the top of Mitcheltree Ridge. I suppose that the Inner Basin has more sand due to eolian influence and the contrary, on Mitcheltree Ridge, is more windy so the boulders are more naked.
On the other hand, what I pay more attention is about the more or less uniformity of stone distribution. It is fairly good distributed. It might be that zone there must had mud and the water or aeolian have eroded sand or mud leaving the boulders or stone or their places.

Wind is good..Spirit's looking a bit dirty 
With a good clean, we might get an extra week or two at HP before running off to sunbathe!

So much for going around Micheltree Ridge as I was theinking the other day, Spirit just bolted right up the side!
I don't think more pics will be downlinked tosol and the few images available now are not enough to make any good driving measurements.
Anyway, I think the manouver was somethink like this:

Beautiful stitch!
--- We whipped out the IDD and took what have to be some of the coolest MI images of the whole mission, on Sol 736. The name of this thing is GongGong, and it is what can happen when you have a very frothy, gas-rich lava that solidifies with lots of voids in it and then gets eroded by the wind for a very long time.
You may ask where a name like GongGong came from. We have several Chinese members of our team, and in honor of Chinese New Year, we have been assigning names from Chinese mythology and history to the rocks at Gusev. GongGong, I'm told, was the king of water from the north, who knocked down Mount BuZhou with his head. You can learn all kinds of things by doing a mission to Mars. ---

I would have thought my embarrassment about The Big Black Rock would have made the answer obvious. Objects (rocks or the sun or moon) on a horizon are expanded in size by the brain. This optical illusion has been studied in depth by many researchers. (While a graduate student, I actually served as a volunteer subject in one of these studies.) When moved significantly above or below the horizon (especially if other objects for reference are nearby), the object 'shrinks' in our perception. No, I can't tell you why.
In the MER example, the different cameras and their lenses and locations on the rover seem to enhance this effect. So many times I've looked at a bunch of 'boulders' in a pancam image, thinking: We'll never get past those! Then when I see the same rocks in the fish-eye hazcam,with the wheels in the frame, it's obvious that we can just roll over those 'pebbles'.
I'm much more cautious now about judging rock sizes, but I'd be willing to wager that those "rover-size" rocks on Mitcheltree were nowhere near that big. A parallax estimate is the only technique I would trust until we're sitting on the thing.
Ain't science wonderful?

Yes it is wonderful. Another very interesting is that the view of stones varies greatly according to the filter level (L1,...,L7) of PANCAM. These filter levels, you will see completely different land, changing from rough to smooth land. Even better, if you see a panoram with analghpy picture which is the best to make a final judgment of what you see. Science never ends in learning.

Bill, I've already said I love this view of Mars, but I would not characterize it as a high resolution image. It has, to begin with, a 5X (?) vertical exaggeration and that would tend to grow a dark splotch, perhaps consisting of a number of rocks, into a "large" structure. This image seems to have been 'processed' in other ways as well. I think you will have to find these rocks in some of the pan or nav shots taken nearby and use a parallax measure to be sure of their size. I'm not the expert at that. Check with Dilo or Tesch or one of those guys.

I've been looking at all of this cool, frothy basalt float lying about, and I continue to wonder where it has come from. We've seen no outcrops of the stuff as far as I have seen. The float seems so abundant that I doubt it is just some debris, blasted from a crater somewhere else. I am starting to suspect it may be left over from some of the previously overlying layers that have been eroded away in this area. Official updates have said that it might be from the basin-filling basalt, or that it might be "something else." Do any of you have other thoughts?

I've been wondering too! As far as I remember, we first saw this as the Diana Ross and/or Fractal Spongebob Rocks as we approached this "Homeplate Basin" region, bounded by Mitcheltree Ridge. We may have overlooked it before, but this frothy basalt is quite distinctive and if we passed anywhere near it someone here would have said "huh?". So I think we can safely say that the source area is here and think that we will find an outcrop here.
This is the wonderful think about Homeplate. We see all these things from a distance as we approach but we have more puzzle-pieces real soon. I'm looking forward to seeing that Homeplate bluff.

Wauw, Pitcher's Mound looks just spectacular from down low. I think it will be one of the signature features of this trek. Can't wait to see a huge big panorama from the edge of Home Plate with Pitcher's Mound in the background: just with one wheel touching the edge of the Plate to say "here I am, made it!".
Ok, no driving tosol (740) but only another attempt to take the "drive-direction" panorama.
PS: The way I read the info on the data tracking web is that yestersol post-drive imagery was only partially executed (2 of 5 navcam shots, no pancam). IMO, probably aborted due to lack of time.

My understanding, but I would like an answer from JB, is that those sequences were simply uplinked to the rover before the plan was included on the database; a sort of "later delivery".
The f0006 is still similar to the 'FS Commanded' but the others I'm not sure of - I've emailed him in a hope he can get back to me before he heads off for a few days of meetings

Yeah... sort of ruins the speculation about either being formed through some wet sedimentary process, doesn't it? Maybe, volcanic, hot 'n thick, nearly cooled last-cough burble to the surface of... what kind of stuff - and maybe not.
We are seeing elements and processes that have little to do with what we see in earthly parallels because we don’t have ‘water’ that is mostly sulfuric acid, an atmosphere of carbon dioxide and temperatures that run to minus 140 degrees at night. Speculation I think is hobbled by lack of familiarity with the dynamics involved here.

I'm really afraid to comment based on this very low-angle and distant perspective from a Navcam. We did get a slightly better view today, but Home Plate appeared relatively flat to slightly dish-shaped from earlier perspectives. The Pancams should be noticeably better, but maybe not good enough yet from this direction, I think.

I never could quite rule it out, but wet sedimentary processes never seemed likely to me for these rocks. I'd love to be proven wrong on that, though.

Just noticed that there was one frame missing from the Sol 729 pan (the one with El Dorado in it) as it had a different sequence number, I think JPL is trying to confuse me! I've now added it in.
Thanks to MMB's panoramas for bringing it to my attention! ...James

Meteor?
Looks like we've reached a top-over point - and see a pass through what might be the extension of Mitcheltree Ridge. The bright sandy spot (in green elipse) seems to mark the point in prior posts that looked to be just North of that ridge.
If so, there was a substantial drive today!

Today for you, but yesterday for me.
I'm looking forward another move today, hopefully to the point (yellow circle at about 27m from the current position) in which Home Plate should be fully in sight.
What can be seen on sol 740 navcams is just half of it. I picked some headings from the route map and translated to the following image highlighting Home Plate, Pitcher's Mound and "Baby Mound" (is there any agreement on the forum about that last name?).

Ellison Mound?
A small geological feature on Gusev but, undeniably, part of it's understanding.
As Doug and this site are, undeniably, part of the incredible adventure of Spirit on exploring Mars.
Well...Just a sugestion...

Well, if there's a really small, quite uppity and rather self-absorbed mound with a bad attitude behind the Mound-Previously-Known-As-Baby, can we call it Harlan?

Tesh, methinks we'll see tomorrow that 'Baby Mound' is a bigger critter than some might think - if it is indeed the top of that mound to the West of HP.
The top of it looks almost as high as HP itself - and if I don't miss a guess, we might run right straight up to the exposed edge of HP in about three days... for some extensive layer examination before we consider going for the surface itself. If so, we're going to be sitting right beside 'Baby Mound' for perhaps quite a while...
Hey, is that Spirit's autonav in action? An UMSF map uploaded and held out front by the IDD?
It's been quite a drive today...
I hope there will be some more images from this fantastic viewpoint...
