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.

Just a reminder that if the color becomes darker than the surrounding soil, one possibility might be a wetting effect due to brief melting in the sunlight? Perhaps there are other possible mechanisms as well as Gray mentions.
Also we apparently see some very isolated naturally exposed ice patches in some orbiter images of the general landing zone, as mentioned in another thread. http://www.unmannedspaceflight.com/index.p...st&p=118986 Steve |

Is this an expected amount of dust accumulation on the magnets after 28 sols?
I seem to remember the rovers' calibration targets staying cleaner than this, but I might be mistaken. -------------------- |

Many of the Phoenix color image sequences are captured over enough time to cause the shadows to change between RGB exposures and thus appear noticably misaligned. Is this because the RGB components can't be made in a rapid sequence? The edges of rocks and shadows will suffer from color fringing across otherwise excellent color panoramas unless attantion is paid to this. Similar products from other recent surface cameras seem to have little of this problem.
