Here's a Sol 22 image of the new trenching area at the extreme right edge of the work area. I brightened the shadow to show the whole trench.

Mark's SSI team produced a wonderful image of the new trench where they seamlessly removed the lander shadow. If I didn't know where the shadow edge was exactly, the image could have fooled me as being completely in sunlight. There's just a subtle hint of diffuse sky illumination in the shadowed area, reminiscent of soviet Venera surface shots.

Interesting; the floor of the trench is quite is flat yet the rubble piles have many "rocks" of various sizes in them. So either those are not rocks but clumps of material, or the "rocks" are only in the very upper layer?

Here is a 8Mb zip of every color image produced by Phoenix to date, absolutely uncalibrated and untouched, with filenames simply a concatenation of the three constituent files' names:

Greetings On this picture I can see the first layer which probably is green or denitely have a diferent colour . ( picture removed, not really necessary ) The same was possible to see in the first digging area but it is my opinion that the first layer is green and is wery thin . In the Meca images was also seen some green sand particles . Didn't they identify olivine in the material sprinkeld onto the microscope? And the material can appear green (see http://en.wikipedia.org/wiki/Olivine). |

Mark's SSI team produced a wonderful image of the new trench where they seamlessly removed the lander shadow. Here's a blog post by Kurt Schwehr describing how it was made. Ah, the magic of Photoshop. |

The lander's shadow was likely removed by using a Selection Tool to selsct the shadowed area and selectively bumping the shadowed area to match the sunlit area.
Ah, the magic of PShop, indeed. --Bill -------------------- |

...so the amount of joint work, and thus joint torque, can be worked out for any part of the digging operation. Thanks! I wonder if the effort of breaking through the surface crust will show up in that data, and if (as it superfically appears to my uneducated eye) there's different structure in Wonderland than Dodo. -------------------- --

Please forgive me for asking an ignorant question...I haven't been tracking things closely. How far is the Peter Pan from being complete?

There is just a 3x2 section to complete the horizon pan, the actual horizon bit (3x1) was taken on sol 22 but I believe lost due to the anomaly. Four pointings of the near field were also taken and downlinked on sol 21. I suspect we'll get most of the remaining data with the 'most-data-rich-sol-ever' going on tosol as a result of the anomaly.

No obvious thread for this, but here is a story describing the various Martian soil simulants being tried.

Remember it can be very hard to get hues right with these stretched jpegs - the regular soil is so dark in blue filters that a white patch can seem overwhelmingly bright in blue filters. Still, there's definitely a hue difference from left to right across that original trench. Perhaps we're getting very close to the substrate.
If you look at Phil's posted image, we've already obliterated that blue-channel bright part of the first trench! No doubt we'll find more as we continue... |
