When I was looking at the Hi-Rise of the Phoenix Lander on the surface I can see channels that look like small river channels. Did anyone else notice this ?
Channels ? |

Interesting to revisit the images shown earlier in this thread (e.g. post 186 - upper image) that appear to show (as suggested) isolated areas of exposed ice, perhaps in natural trenches of some sort. They appear quite consistent with widespread subsurface ice and it's neat to see the ice showing itself occasionally like this.

Found a neat video on the Photomodeler web site where they use the software to make 3D models from Phoenix stereo pairs. They do one of the lander legs and also a trench:

Might want to be careful with that Photomodeler. It brought my PC (a middle of the road model) to its knees. But the little I was able to see of it was impressive.

Thanks for posting that, Joe. That is some very nifty software. Too bad it is so expensive. I'd like to get it, but I can't justify the expense.

Deliberate "self portrait" shadow shot or just coincidence? A simplistic color composite based on Phoenix SSI raw images, sol 030:
A lower Sun angle with longer shadows would be more spectacular, but without a wide-angle NAVCAM type lens the full shadow might even get too big to fit in a ISS field of view - at least for the entire spacecraft. Then with the need to take multiple images you get more of that color banding due to the shadows moving of course... Airbag [Edit: Titles have now been added to the sol 30 page, and this one is from a sequence called "1378-8: SSI Solstice Image", so no coincidence! This shadow is thus the shortest noon one.] |

Nice.
Now try viewing that with 3D specs (reversed, with left eye blue) to see that shadow floating ABOVE the ground! This is a trick I have used in our physics lab to make 3D shadow shows - illuminate objects with two colour spotlights side by side and view the cast shadows with 3D specs. |

What are these for? Looks like the lowest resolution possible of the horizon and the sky??? any guesses? <sol 29, 30> -------------------- CLA CLL

Look at Marks page - they are described as sky water observations. Solar filtered ( thus long exposure and noisy ) horizon obs.
