If someone knows an appropriate JPL address that will actually get to them - I'll sort out a card or a little pressie or something

Sadly I dont know an appropriate adresse - maybe Steve personally with a great thank for his current updates on the Cornell site. -------------------- |

I was thinking more getting a little garden trowel - painting it up with some gold spray paint - and sending it to the engineering team as a thank-you gesture for all the digging they've been doing in the mars-yard
Then again - last time I did anything like that was a little beagle 2 christmas card that I rendered to look like B2 stuck under snow from overyone at the old Beagle 2 yahoo group I started in '02. I dropped it off at the space centre here in Leicester, and Beagle was never heard from again  Maybe I'm cursed.  Doug |

Only the right one seems to go a bit deeper, but would the nature of the Rocker-Bogie Suspension system not indicate that the middle wheel is rising then? -------------------- "I want to make as many people as possible feel like they are part of this adventure.

Don't think so: it'll stay in the same level at best. Rear wheel is sinking in, middle wheel will stay the same: WEB will get closer to the surface..... |

I can't tell that the chassis sunk in at all. I wouldn't worry too much. When that wheel gets to the dirt pile that the middle wheel ahead of it has been churning up, we should see some lift.
On a side note, I suspect the people who study soil composition are having a field day with those 'animations' showing in great detail how the sand responds to the wheels on a minute by minute basis. |

But the WEB ( and thus the Hazcams ) dont appear to be getting closer to the surface - so I think it's fair to say that perhaps yes - the middle wheels are rising a little
I've run all front hazcam driving all together as one long animation... Front Left http://www.unmannedspaceflight.com/doug_images/FL.gif 800kb Front Right http://www.unmannedspaceflight.com/doug_images/FR.gif 450kb I'll keep adding to them, and make a .mov of all four corners when they're out Doug |

During my study physical geography (yeeeears ago) i did some work on mechanical properties of soil and my gut feeling says , that we all can be very happy about the fact that there are six seperately powered wheels ! I bet this stuff is even very hard (if not impossible) to traverse by foot !! |

BTW, a little golden garden trowel could it be  Maybe with a pack pudding powder in respect of our first impression about their sandbox

According to the last motion pictures, I am convinced that Opportunity will get out of stuck sand. It is approaching to the decline slope and also a more compact sand in which they will help to MERS B to come out of a situation with flying colours.
On that point. the motion must be keeping rotating enough distance until the MERS B reach to the point where the sand is flatter and more compact. After the MERS is alive, I am doubting if the MERS is capable to distinguish by myself to the different type of sand in order to avoid that the future will happen again? Rodolfo |

Do we have any power numbers for Oppy? Surely sat there the power levels must be down, we prolly need to get a cleaning event on oppy soon.
I think I saw in one of Steve's reports he said something like 500w/hrs... I could be wrong. |

Nice to see that there are 3 Sol's worth of animations there (by the shadow movement)... Looks like a very first operational rototiller on Mars, that's gotta be something for the history books...
