Another possible traverse is shown in Geologic mapping and characterization of Gale Crater and implications for its potential as a Mars Science Laboratory landing site by Anderson and Bell. Traced out in Google Earth it looks like the white line below:
The yellow line is the traverse from MSL Landing Sites: Gale, Reconsidered (PDF) -- Edgett, Milliken, Grotzinger, Malin They end up at the same area, the "erosional unconformity." Total length is 22 km. Another view: -------------------- |

Still trying to get a better handle on where MSL is likely to be driving, in a year or two.
While the traverse from Glenelg to the base of Mount Sharp seems totally shrouded in mystery for now, in the mean time I’d like to get a better idea of where the proposed routes at Mount Sharp show up on the fabulous view from ground, that JPL released yesterday. I’ve tried to ID the corresponding features with letters – black in the ground view, orange in the satellite photo with traverse routes. Not too sure about some of them, so some helpful tips would be appreciated. Has anyone tried to map the traverse routes on the ground view yet ? (Thnx) |

Walfy did a similar feature correlation a couple of days ago which I think was more accurate- using the stereo orbital view, as he did, really helps make things clear. I'd love to see someone take the next step and add the traverse routes, though...

They mentioned in the briefing yesterday a plan to do long-baseline stereo with Mastcam of that spot from their new position. That'll really help line things up.

There was a great picture released yesterday during the press conference, on which the MSL team had spotted, and highlighted, a Curiosity-sized rock off in the distance. I thought this might be useful in giving a sense of scale to some of the features over there in The Promised Land, so I hit Photoshop, and put that rock in the landscape at various points, to give - I hope - a pretty good sense of scale of the terrain Curiosity will eventually drive through. Not claiming this is 100% accurate, but it does bring it home to you what an incredible place is ahead of us.
So, in the following black and white images, look for a dark line running top-bottom, with some dark dots at various points along it. These dots are clones of the aforementioned rock, to show the (approximate) size of the rover. (Note: the line is just an imaginary 'trail' through the landscape to make spotting the 'rover' easier. Not suggesting it's a possible traverse!) The scale really hits you in the face when you look at it in 3D. I've circled rocks the same size as the rover in the following images... On that second 3D image the feature circled is actually slightly smaller than Curiosity, but there was nothing larger in the area to use. -------------------- |

Full size version - with virtual Curiosities show - of a purely imaginary traverse through "The Promised Land", including the "Martian Monument Valley"...

I'd love to see someone take the next step and add the traverse routes, though... John Bait taken I haven't quite got the field of view exactly the same (mainly due to my computer throwing a wobbler with all the HiRISE DEMs I keep pushing at it), but it's not a bad match. It's views like these that remind just what amazing datasets these HiRISE DEMs really are. And of course, the real view from the surface is pretty sweet too But it's a bit difficult to make out the exact routes from that angle so I thought I'd take a step back at the larger picture. Once you get your eye in (follow the arrow) it's fairly easy to see where Curiosity is looking. All in all it's a pretty good view round here isn't it? Pete |

Any chance of giving the mound with the Curiosity rock on it a name? It shows up a lot and it would be useful to label it in various views as a central landmark, thereby enabling viewers to get oriented. I think it's "F" in Jaro's pic. I know JPL will give it a name later, but couldn't we use a temporary name?

Now I can see where my errors were.... especially hill "F" was way off. Hopefully this one is much better... |

Right side is upside down, Jaro.

I think this was intended - it was rotated to match the orientation of the features in the MSL image.

I make 3D animation from this one image:
http://mars.jpl.nasa.gov/msl/multimedia/ra...1_DXXX&s=24 My workspace: 1) add layer with gradient 2) with lasso I select some rocks and simply little brightnes this area 3) save depth map 4) add color image and depth map to stereo tracer and generate animation AVI Here this animation (1.7 MB) http://ge.tt/50xaTJN/v/0?c and anaglyph version -------------------- Adam Hurcewicz from Poland

Here this animation (1.7 MB) http://ge.tt/50xaTJN/v/0?c Great job ! Really impressive ! Do you plan to do the same kind of animation for other pairs of Mastcam pics ? -------------------- |
