Maybe it was intended as a sky ob, but the arm was in the way?

QUOTE (akuo @ Sep 17 2008, 02:21 AM)  Confusingly, the Phoenix site doesn't seem to talk about the last cell. They say "A small pile of soil is visible on the lower edge of the second cell from the top". What is going on here? Did they add material to cell #2? My understanding: Originally they skipped cell 2 (reason to me unknown) and dropped a Stone Soup sample on cell 3, the one farthest away. That stuck and didn't succeed, so they tried again and dropped another really big sample from Stone Soup to cell 3. That also was sticky and just piled up. Recently, they delivered a sample from Snow White to cell 2. Some of that soil stuck to the screen too. but enough got in for success. They sit now with 3 used WCL cells, 0, 1 and 2. Cell 3 hasn't been used but its mouth is covered with a big clump of soil from Stone Soup. |

Hey look! A little bolt! You'd all have missed that if I hadn't pointed it out now, wouldn't you?

The only thing missing is the Wicked Witch saying, "I want your little dog!"
That animation is cool... and creepy. |

Psssst, guys... wanna see something
 ? I was bored - should be attacking this huge pile of editing, but really not in the mood - so I thought I'd try animating some of the microscope images from Sol 112, just see if any little grains shifted... I think this classifies as "shifting", don't you..?
Cute or what?  ... and in colour...
... and a "jewelised colour" version on my Gallery blog... -------------------- My Homepage

Good eye Stu. This is amazing. I took the one from your web page and aligned the backgrounds (somewhat) to sort of stabilize it. It then makes the whole pile come alive.

 Reaction #1: woooo-weeee!!! Disco dancin' dust grains!!!  Reaction #2: Damn. Wish I'd thought to do that...  You're a genius Dan! -------------------- My Homepage

Great animations, but you guys obviously know something that I don't because my initial reaction is:
Reaction #1: woooo-weeee!!! Disco dancin' dust grains!!! (apologies to Stu for borrowing his words) Reaction #2: This is the weak magnet - why is it so!!! Is this a function of a variable magnetic field or just vibration of the wheel with the weak field enabling some movement? What are the magnetic parameters for the magnetic cells? Are these pemanent magnet or coil? Is this a deliberate feature of the OM capability? |

I'd have to think it's wind moving the grains, young grasshopper...

I would agree since they appear to be moving at random, whereas if this was due to the influence of a magnet they'd more or less be rocking back and forth together.

Wind? Within the dark confines of the OM? Ommmmm - old and wise Master Other Doug, the ways of the lander designers and the subtle effects of the Martian environment are more wonderous than ever I thought.

Wow! That's really nifty, EGD. I'm not sure which forces could be controlling the disco dance. I'll throw electrostatic discharges into the suggestion box. OMG, that is really nice. I suppose motor vibrations transmitted through the solid members of the lander might possibly cause a similar effect, as fredk suggested elsewhere. You would have to know the timing of all motor operations with regard to the timing of the capturing of the MI images.
It would be helpfull to know the lengths of time between the images. I'm too busy to look for that information.  Mars exploration continues to be quite a lot of fun, is it not?

They drive a motor to pull focus - so that could cause vibrations to move material.
