Am I imagining things or is the Beacon 'Cabo' the only one that shows uplift rather than sag? Does this suggest something fascinating about the underlying structure, or is it just that a fragment of an upper 'evaporite' unit survives atop Beacon, and is lost everywhere else? unsure.gif


Two thoughts: 1. Do we have uplift or was there a hill here before the Victoria impact?
2. If there is uplift only here could it be evidence of an oblique impact? I've been wondering why the dunefield, presumably in the topographic low, is displaced northwards from the crater centre, towards the highest part of the rim.

Well done diane, nice one! smile.gif Welcome to the image processing club (from a VERY junior member!!)

Brilliant again Stu, and diane and everyone. Another grand night out on Mars.

Just a thought - perhaps we should hold a press conference express express . . .

I agree that there may have been a hill before Victoria; the Beacon appears to be cut from a hill if you look at what's behind Beacon up on the annulus.

However, there's still a reason for the uplift, and the uplift doesn't appear to have been even because of the angle of the layers in Beacon's face. So we still have a question, even though Victoria's impact may have destroyed the answer.

Two thoughts: 1.

As an adherent to the "Ancient Victoria" school of thought, I wouldn't hold to the "hill" thought. This area, to my eye, is the quintessence of "flat". The only hills I could imagine on this plain would be parts of the rims of craters younger than Vicky. The oblique impact idea did cross my mind however. Some tough, bulky remnant of the original rim could be holding up "Cabo Beacono" - that is, retarding or reversing its collapse.
I think I wanna closer look at it - #$@& clink - hurry up pancams cool.gif !

After looking at these pictures and the torrent of MRO photos (hey, there's a good idea for the future MRO firehose...a BitTorrent!) all I can say is.....

"You're going to need a bigger jar"

My apologies to Martin Brody...

I already gave up...I'm setting up a direct deposit from my paycheck to the jar... sad.gif

Well, it's not like I was the cleanest-mouthed guy in the Solar System in the first place... smile.gif

Hey fellas. We should make a swear-fund. With interest it could finance the next Mars mission... laugh.gif

Not a bad idea! smile.gif

Speaking of next missions...imagine MRO's replacement. Will we have multispectral 1 cm resolution of the entire planet? blink.gif blink.gif blink.gif

Hi,

Here is the Sol 959 Navcam view (always build with MMB rolleyes.gif ... ) :

Nice job, Ant. Those dunes in the bottom fascinate me. I imagine them as water waves that were frozen in an instant. I picture a series of water waves bouncing off the sides of a pool and then suddenly solidified. smile.gif

I hope we get to see the south face of The Beacon in better light.
Tman
For some sunlight on the south face of The Beacon in the near future it's the wrong season (I guess). But they could take a picture with more exposure, couldn't they?
Gray
Of course you're right about the seasonal problem (Doh! gray hits forhead with heel of hand). It just seemed to me that in adjusting the brightness on these images of the Beacon, a lot of the contrast was lost. Cross-beds often show up as some subtle variations in contrast when low angle light is striking the outcrop.
Bill Harris
>sunlight on the south face of The Beacon in the near future it's the wrong season...

It is. But OTOH good photographic technique will mean that the outcrops should be photographed under different lighting conditions to optimize the views. Low angle lighting for fine textural details, moderate angle lighting for overall details and soft, indirect lighting for albedo or color details. Oppy needs to take several images of each area to help chase away photogeists...

--Bill
diane
Gray, I'll agree that adjusting the photo after exposure is less than ideal, but the real information loss is in the original exposure. It would be nice if Oppy could do what's called "spot metering" to expose for a specific area of its image. Either that or deliberate overexposure to get more shadow detail is what's needed. I don't know that Oppy is capable of either.

There are better alternatives than adjusting brightness or contrast, though. The better tools in Photoshop are "levels" and "curves" adjustments. They're available under the Image menu as adjustments, but the better alternative is learning to create adjustment layers (in the layers palette) so that the adjustments don't alter the image, and you can go back and change the adjustments (or hide them or delete them).

It seems that Opportunity is close enough to the beacon to take pancams where the whole field of view is the cliff. There should be no "spot metering" needed in that case.
Gray
Thanks Diane. I have only dabbled in image analysis. I'm certainly not at the level of most of the folks on this forum.

Is there anywhere ".jpg" version of that Cape Verde & Cape Frio images with little rover standing on them?
They are shown on latest update but I cannot find that images anywhere...

Seeing these pictures just makes me feel like a little kid again; I want to go running or tumbling down into the crater, kick up the sand, race across to the other side and climb up the rocks, then go digging around and pretend that I'm on Mars -- oh, wait, this is Mars! It's a grand feeling, and the only drawback is not actually being there, but as I share this problem with everybody else on Earth I may -- in time -- learn to live with it. smile.gif

Did anyone else notice the tracks left by a few boulders as they rolled down into Victoria ? Must have been "recent" events.

...It would be nice if Oppy could do what's called "spot metering" to expose for a specific area of its image. ...

We've seen some of that at Endurance when they took longish exposures with extra bright sky above the crater rim (looking more or less up-sun), and the overexposed image bleeds down into the frame below the saturated area, producing a ragged-edged area of total whiteout and normal picture one pixel below the edge.

Seriously overexposed front hazcams tosol. I've never seen this before in hazcams. Also a very slight movement/rotation.
Oersted
Maybe they were interested in what's in the shadow of the rover, that area is correctly exposed.
dot.dk
An interesting thing seen in tosols images.

The latest hazcams shows the IDD deployed and doing work with RAT, MI etc.

But Oppy also bumped a few centimeters before starting the work!

Indeed interesting. And Pancams: a full-filter set of Cabo Frio (she's been working on stratigraphy, good girl) and an L257 of the pre-RAT brush. No time to post right now.

Nope. That 959 hazcam is the *penultimate* one not the end of drive one. There was no bump yestersol.

I see this one has already been done. Never the less, here's a 360x90 equirectangular projection of the Sol 959 Navcam pan facing East, followed by the full 360x180 version facing North, suitable for viewing in FSPViewer or another spherical panorama viewer.



fredk
Thanks for the pans, everyone! Indian3000, that pseudo-polar image really is stunning - it clearly shows our location near the tip of Verde, especially if you view it at a reduced scale.
dvandorn
I'm a little concerned about these small movements we're seeing in the images between sols, especially since I figured they had already reached their "perch" position.

How certain are we that the ground underneath us hasn't shifted under Oppy's weight?

Where are we seeing such movement? As long as there's no movement when the rover motion counter stays the same, I think we're fine. smile.gif I haven't noticed anything unexpected.

Over the past two days, I've been reading posts here saying things like "Well, look, it moved a little bit since the the last image taken, so I'm having a hard time stitching it" and things like that. I could be wrong (I often am... biggrin.gif ...), but it seemed to me that this had been said after we had reached what was supposed to be her parking spot for the solar conjunction and all that photo work she'll do while we're out of touch.

If all that was being referenced was planned small, adjustment moves out to the perch position, that's great. I just hadn't heard much said about such fine-adjustment positioning, and so I wondered about the changes of position that had been discussed.
