Here's the location of the rover on Google Mars.

Same thing, just closer.

And this is traverse map they have on the Curiosity Analyst's Notebook.

Since Sol 133 Curiosity has been moving on that small area.

...So Curiosity has covered about 70 miles already? Impressive.

Maybe we should add a turbo next time ;D

No, according to this site it has covered 4389 metres.  :)

ArMaP, I take it that the numbers are SOL stops. Back to the lizard, what was the sol number and that stop. I want to stay on one photo if we can. Try and lock it up better.

I can get to the notebook site but not the map. geez what is up with the white wall workers.

The "lizard" is from Sol 193 (the start of the file name shows in which Sol the photo was taken), but as Curiosity has moved in little steps from place to place there's not a photo with enough resolution to show that.

SKY:

So far, my really rough math is telling me that the Lizard should be around 150 feet away from the camera. That would make it closer to a small dog than a rat as we know them. Many Lizards are that big on Earth so it is not impossible.  Lots more work to do. The speed of the shutter was at .07 or 1/15th of a second. Average film is 0.033 or 1/30 of a second So they must be keeping it open to get more light and a deeper focus.  Depth of field.

The total focus range is around 765 feet. The minimum was 56 feet but I dont think anything or many things are in that range. I am putting that big rock in the center at 100 feet and working in and out from it. That large rock is in good focus and most likely what the camera set on. A nice target.  As you can see, everything that is behind the Lizards ridge is out of foucus and blured so that hill area is over 800 feet away. I think everything you can see clearly is less than 250 feet.


ArMaP, Can you pick up the height of the Mast Right out of that list. It looks like they set it to zero. If at zero We need to know what zero is above ground level to work out the projection angles on the CCD relative to the photo.

No "thumbs up" icon on Pegasus, so some virtual gold and an even more virtual "thumbs up" for you. :)

I will look into it. :)

Edit: From this page:
...the Mastcam is 1.97m above the wheels. The M-100 provides a resolution of 150µm per pixel at a 2m distance and 7.4cm per pixel at a distance of 1000m. The other Mastcam has a resolution of 450µm/pixel at 2m and 22cm/pixel at 1km.

I hope that helps.
I will look for more. :)
