Paolo - "Seriously, the tracks Astro0 posted are way too close to the rim."
Hey, I didn't say that I knew how to drive  but I do know where we are going!  Astro0 |

Good hunch there, EGD.
QUOTE (RoverDriver @ Sep 28 2008, 08:10 PM)  ... On the image above, the end of your tracks are exactly at the second (and last) imaging location at VC. The first location is at the edge of the rim just above the 150 marker. hmm...That looks like a good set up to do one more long baseline stereo pair. If so, it would be nice if it could be done in color.I'd also suspect that if the second stop on the rim is the last, that afterward, the route would go pretty much directly south from there. -------------------- ...Tom

I haven't heard any mention of superres or WBS on the first target.

The database might announce the intentions. I wasn't expecting superres unless something exceptional was noticed.We only need overlapping images from those two locations, and it would seem neglectful to not collect more long distance 3D from the SW corner of the crater before Opportunity leaves. But, what do I know. -------------------- ...Tom

QUOTE (djellison @ Sep 28 2008, 11:39 AM) Driving limited perhaps by time rather than power - so if you forgo the imaging at the end of the drive before stopping for the PM UHF pass, you can get more drive time into the schedule. More info on this loooong drive: it started around 12:45 and it took 'til 16:30 to cover those 150m with some stops in the way to confirm "all is well". This one hasn't the record in terms of distance, but perhaps it has the record in terms of driving time. |

QUOTE (RoverDriver @ Sep 28 2008, 12:07 PM) (I hope) we are disciplined enough to think about the goal which is not beating the record but to get to Endeavour. Interesting comment. Perhaps I'm reading too much into it, but it sounds like you are saying that very long drives are not good for the long term mobility of the rover.

No, I really mean that while trying to do long drives we still maintain the rover safe. The goal is getting there, not die trying to.

Please, excuse my ignorance. Would Oppy need to do a cool down stop if it drove for too long?
(I know, it isn't a F1, but the martian air isn't very conductive either.) |

Dunno.
But what I really know is that our fellow rover (or the driver behind  ) is a little bit "drunk".Check the wheel marks: http://qt.exploratorium.edu/mars/opportuni...23P1312R0M1.JPG I know, I know! That's deliberately made to ease the work for the autonav (or whatever it's called). |

Drunken sailor walk
I don't think the rover motors would overheat. With 900+Whrs during high summer, the WEB may get to an overheating situation ( as happened at the summit of Husband Hill briefly ) - but the rover motors are so exposed that I find it hard to believe they could get warm to the point of being worrying.

QUOTE (djellison @ Sep 29 2008, 10:08 PM) Drunken sailor walk Doug Realy? I thought it was more eratic. Well, last such drive was over 1 year ago and I don't remember very well. I didn't though we'll ever have to use it for real! Anyway I guess she'll use lot of this technique for quite a while. I intentionnaly say "she" because I guess we can call this "self navigation" as opposed to "ordered navigation". -------------------- |

I don't think this was an example of the drunken sailor walk - but that's what they called it when the rover stopped quite regularly to give autonav / visidom something to see.

Are we on a day on/day off schedule for driving now or can we drive everyday?

I would say at the moment we're on restricted sols.
