QUOTE (Stu @ Jan 31 2009, 04:02 PM)  Of course the stuck wheel turned out to be a good thing, 'cos it exposed that luvverly silica-rich deposit, but still... can't help thinking "Awww...."  If I'm correct they had a method on the old Soviet Lunochod moonrovers to fire some pyro's and basically cut the axis connecting the wheel with the motor, in case the thing got stuck, leaving the wheel to turn freely. It is a pity nothing like that exists on MER, I guess driving would be a lot easier if the wheel just could turn freely.. Regards, Geert |

I would NOT like to be the person responsible for either writing the code for that pyro, or pushing the button to fire it...!  Spirit's doing just fine, I think, dragging her wheel like a lame puppy dragging a leg. It's just one of the - many - reasons why we adore her so much. (Cue cries of "It's just a robot!!!!!" hahahahaha...) -------------------- |

Yes, just positioning for the final climb, I think.

Another dust devil: http://qt.exploratorium.edu/mars/spirit/na...CJP1561L0M1.JPG (and moving faintly across the next few images I think?)

I don't think they're moving 'this way'. Just more of them as the season moves on, thus more chance of seeing one that is closer than before.

QUOTE (djellison @ Feb 2 2009, 01:30 AM) I don't think they're moving 'this way'. My thought is that Spirit should move toward a spot where a cleaning would be most likely. Can you recall instances of winds moving over Home Plate, and how many 'cleaning' events took place while there? (My memory is faulty, but I can vaguely remember only one.) Maybe that isn't an option, but if closer to full power could be restored, I think the possibility of getting to 'the promised land' - or nearer to it - could be again looked at. |

They're too random and rare to be stated as likely at X location. We're less than 25m from where we had significant cleaning a year ago. We've had them in the hills, we've had them on the slopes, we've had them on the flat.

According to the latest update, more of an unlucky encounter: The drive on Sol 1806 covered about 30 centimeters (1 foot). The rover team had planned a longer drive, but Spirit stopped short, apparently from the right front wheel encountering the partially buried rock visible next to that wheel. |

There's another attempt in today's schedule (1809).

Also in the latest update:
QUOTE A diagnostic test on Sol 1805 provided an evaluation of how accurately Spirt's accelerometers sense the rover's orientation or attitude. The testing was a follow-up to Spirit's mistaken calculation of where to expect to see the sun on Sol 1802. The sol 1805 results indicate the accelerometers may have a bias of about 3 degrees. This would explain why Spirit pointed a camera about three degrees away from the sun's actual position on Sol 1802. Maybe, to anthropomorphize our friend Spirit, she's feeling a little dizzy after being tilted at wh3 for so long and then abruptly returning to level ground.

Some fresh images on the web from sol 1809. Spirit is inching her way to the top of Home Plate.
