QUOTE (CosmicRocker @ Dec 17 2005, 08:24 AM) Steve's recent "quick" update was interesting. Just a few days after saying they were heading for Home Plate, he says it's either Allegheny or El Dorado. Is Allegheny ridge that linear ridge with the mesas, trailing away from Home Plate? If they climb that, they would have good views of El Dorado and Home Plate, wouldn't they? And Home Plate would then be on a line between there and McCool Hill. Maybe Home Plate is not written off just yet. At least, I hope not. According to the latest Spirit traverse maps (http://marsrovers.jpl.nasa.gov/mission/tm-spirit/index.html), Allegheny Ridge is located halfway between Spirit's present location and Home Plate: |

At the Hayden this past Monday (12/12/05), Steve said that Home Plate is the next big target, with the goal of reaching it by about sol 750. He showed a cool picture of the approach to Comanche By about Sol 800, he said they MUST be on the sunny north facing slope of McCool Hill. Gotta maximize energy output with the fast approaching winter or Spirit could die without power to the heaters. According to Steve, the unthinkable (unponderable !! ) almost happened last winter. Spirit is currently at about 600 watt hours. So our baby has to get moving !!! |

Comanche is big!
From memory Comanche is about 10 meters distance. Comanche is about 15 meters wide and mayby 3- 5 meters high Commanche Flicker Warnig: File Size 500 Kb [attachment=2888:attachment] |

A glimpse of El Dorado?
This flicker is composed of the two navcam images immediately to the right of my previous flicker. Comanche, or the main portion of Comanche, is partially visible on the left of this flicker. We are looking through a "saddle" between two outcrops. What do you see? El Dorado navcam flicker Warning File size 700 Kb |

Regarding Home Plate. I'm still keeping my fingers crossed. I'm "on the road" and not able to keep up with all of the details. Do we really know that _that_ is Allegheny Ridge?
QUOTE (stewjack @ Dec 17 2005, 02:46 PM) It is big, and it's Freakin' Red, too, like Steve said. Might that mean that this outcrop is showing signs of secondary alteration, and not as much pristine olivine as we have observed recently? The weathering of this outcrop also flagged it as something to take a peek at. -------------------- ...Tom

Thank you for those glorious pictures and flickers I can't argue with the 2 1/2 meter height measurement. My width measurement was not done at the same point as my multiple distance measurements. Consequently, the parallax converters width number varied with each distance measurement. I'm still a little surprised that my guesstimated height was that far off, but at least it is taller than Spirits mast! |

Like I was saying on the Comanche thread...:
With Doug's and Nico's anaglyph we can see that behind Comanche the terrain descents abruptaly...If you compare the distance to Gusev's floor from the patch of terrain right aside Comanche and the one where the dark sand rules there's is a great difference over there...It looks like El Dorado is divided in three diferent areas, the dark sand unit, a more homogenous area with almost no boulders in it and, closer to Comanche a depression with more irregular terrain... So...the dark dune field is just a part of the formar Ultreya shadow...I guess, like this: http://img.photobucket.com/albums/v352/ustrax/123.jpg -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

From Commanche rock to El Dorado is very flat, perhaps one of the biggest naked outcrop I have ever seen. From here to El Dorado, the transverse would be very easy, perhaps, maybe, one non-stop up to the border of El Dorado to do MI on the dark sand.

I'd agree - it'd be the work of 2 sols at most to get there, easy driving on good terrain. Then head SE to the next target.
