Here is the matching between the (low-res)Mastcam/Navcam panorama of the dunes field and hills at the bottom of Mount Sharp, realized by James Canvin, and the CTX observations drapped on topography. The middle and bottom pictures are snapshots of Explore Mars website, stitched on PTGui (which explains why you see 2 Curiosity rovers - don't worry, you're not seeing double !). The blue arrow on bottom picture indicates the location of Curiosity.
Distance between Curiosity and each feature has been computed on Google Earth.
One canyon is located near point 15, and another one between points 17 and 18.
Phyllosilicates may be located between points 16 and 19 according to CRISM hyperspectral observations and Ryan Anderson paper.

This matching follows my last matching experiment focussed on the rim of Gale crater.
Tell me if you see any mismatch !

I know exactly what you mean about saturation in the MER jpegs. But on the other hand, look at an MSL navcam shot like this one:
http://mars.jpl.nasa.gov/msl-raw-images/pr...AUT_04096M_.JPG
In the image proper, the brightest pixels are in the sky in the upper right, with levels of around 130.

If you look at the time of exposure of this image, you'll see, that it was aquired about 1,5 h prior sunset. So there is less of light and when we account they have now different software onboard, it is possible, that in the future they will change exposure time to make sky more white, than in this evening image. So now we see something like see someone, when captures images with the same exposure time through entire day. Morning and noon images have different lightning conditions.

At the very end the interviewer asks Steltzner his own future plans, and he said, quote: "I'm out of a job, officially."

One of the most moving memories I have of Monday morning is Adam Steltzner at the first post-landing press conference. (link to Richard Cook's introduction: http://youtu.be/FVzfDZlEwaU?t=28m0s )

Wheee this is anaglyph 3D!! You will need those glasses.

This is a crop of the Map-projected reduced-resolution (PNG) version of the PSP_015073_1755 anaglyph graphics file.
Note the drop-off to the east of what I believe is the landing site



Next look at the Navcam anaglyph jamescanvin posted in msg 556 - Is this showing the same drop-off? Any opinions?

Here is an image created by colorizing the Navcam panorama from the Mastcam thumbnail panorama. Since I don't have any information on the exact viewing geometry or projection etc. of the two panoramas I measured lots of control points in the two images and then used these to warp/resize the Mastcam image and then copied the luminosity information from the Navcam image into the warped Mastcam image. I then made minor manual adjustments to the lander color where color information is available but I was mainly interested in Mars' color.

This was partially experimental - I have often done something similar when processing Voyager mosaics of Jupiter where only minor warping is needed (typically only for parts of an image where images overlap) but here a lot of warping was required everywhere. This turned out way better than I expected:

Oh, my, that is spectacular.

[James Sorenson]

Very Nice Bjorn!

Is this showing the same drop-off? Any opinions?

I don't think it's the same- the terrain below the dropoff in that HiRISE anaglyph is quite a different texture from the dark, smooth, stuff we're sitting on, while the terrain below the dropoff in the Curiosity mosaic is made of the same stuff we're sitting on. I think the dropoff seen in that HiRISE anaglyph is a bit further away.

The best yet! Here it is with exaggerated topography. The dunes clearly reach up the lower slopes of Mt. Sharp.

so good.

I was looking at a anaglyph and some dunes seems to literally drape over a small cliff. Does anyone know what the vertical exaggeration is on the HiRise anaglyphs ?

[Ondaweb]

Very nice indeed.

The vertical exaggeration in an anaglyph depends on your viewing distance, so it's not a fixed number. You get zero exaggeration when your eyes are looking at a point on the anaglyph with the same convergence angle as the convergence angle of the original images. The convergence angle of your eyes depends on the ratio of the distance between your eyes (fixed) and the distance from your eyes to the screen or paper (not fixed). Try it- you'll see the apparent vertical relief of an anaglyph increase as you move back from the screen.

I realize that there are no plans to visit EDL hardware that has crash landed. However, after seeing the constellation of impacts from the tungsten ballast, I was wondering how deep a crater each 25kg mass made impacting the surface at over 1,000 m/s? Would these robot-made craters be safe to approach and have scientific value for MSL's instruments?

[MahFL]

Thanks John, closer does look more realistic. I spotted an old old crater half covered over with a layer of deposits, this place is awesome.
