QUOTE (MahFL @ Apr 8 2005, 12:48 PM) I am glad they are moving on, those were just 2 small craters, not much new to be seen there. On to the older crater with some small cliffs, and some etched terrain    I'd say straight to Victoria, and some etched terrain after that. Erebus is ancient, so a lot is erased. Victoria is more fresh and thus more interesting considering make-up of the mother-rocks deep down. Some imageing at Erebus (and no RATting), some snapshots during traversing further south (and no RATting), and get in there (and RAT  RAT RAT ) !I want the science, I want the view and i want it soon ! Imagine an outcrop 10's of meters down, and no RAT capability  Imagine a dead rover near the rim of Victoria.....  go-go-go oppy ! |

That of course is based on the assumption that Erebus and the etched terrain won't contain something too compelling to pass up. I guess they could brush a rock, and after studying it, if the results are still ambiguous and compelling in a way that a RAT-ing might clear up, then go for it.

Anyway I see etched terrain as a more important target. Victoria is just Endurance on a bigger scale... -------------------- Antti Kuosmanen

If the etched terrain turns out to be the same stuff they saw in Endurance and Eagle, they will move quickly to see if Victoria has something else to offer. If other things are present, it is important to investigate - It would be terrible to have tantalizing pancam data on a rock and have skipped it to get to Victoria, especially if it turns out to be a bigger Endurance. -------------------- |

I admit that I'm more captivated by the spirit of exploration than the science. I'm hoping we make it to Victoria in good time and then beyond. I'd love to see Spirit head for Thyra soon as well.

QUOTE (djellison @ Apr 8 2005, 03:47 PM) They started drivin Spirit backwards after it's wheel issue - and that has since vanished We have 12 healthy wheels on mars. The only issues I know of are... Stuck IDD heater on Opportunity that gets turned off via deep-sleep at night Slight non-damaging short on Spirit somewhere Oppy Mini-TES still off-line for analysis Spirit RAT teeth possibly worn out. The last point says a lot about the composition of the rocks between Gusev and Meridiani. As of December - the score was Grind Brush Spirit 11 39 Oppy 22 8 Now - since then, I believe we've done four rattings on Spirit, and 1 on Opportunity - so the score is probably around 15 - 21. Yet Spirit's the one that's worn out Doug puts in perspective whos rocks are harder. That stuff oppy is rattin in must be soft like chalk/limestone. scott |

QUOTE puts in perspective whos rocks are harder. That stuff oppy is rattin in must be soft like chalk/limestone. scott I never did hear any official analogy suitable for everyday experience the texture/density of the Meridiani bedrock. Likewise, ive always had the same impression by looking at the chalky images and grinds that that was whats it like, similar to a bed of natural porous chalk; but then looking at the 'weathered' surfaces of the rock, its looks more like burnished unfired clay. The rind that makes these surfaces appear hard as limestone cave formations seems thinly painted over compressed silty salt cake that quickly fluffs away under the rat. but i digress, whats the offical line? |

I have a web page you might wish to look at with links to various "final" versions that have been published. These are cylindrical projections, and perhaps they can be reprojected into polar if anyone would like to try. http://laps.fsl.noaa.gov/albers/viking.html Later, Steve Albers -------------------- Steve [ my home page and planetary maps page ]

QUOTE That stuff oppy is rattin in must be soft like chalk/limestone. The "Eagle Formation" is said to be Keiserite (Magnesium Sulfate) which has a Mohs Hardness of 3.5, which is only slightly harder than Calcite (Calcium Carbonate). This hardness is for a single crystal of Keiserite, and I'd expect the pseudo- or microcrystaline rock to be no harder and probably softer. It may be chalklike in hardness. --Bill -------------------- |

Technical problem? I notice that Opportunity hasn't moved for some time - they haven't deployed the IDD which they often do during weekends or briefs science stops.

Flash was probably quite full - I noticed the Explo. had a LOT of images from the Vostok pan come down over the weekend. They probably spent the weekend doing all the UHF passes they missed last week, charging batteries and writing the sequences for this week in which, I imagine, we might well see some BIIIIIiiiiiiiiiiiiig Drives

Well, as of sol 430, still not much on the horizon.
