QUOTE (AndyG @ Aug 30 2005, 03:13 PM) Of course, what any good geological vantage point needs is some information for the tourists. (And a cafe - preferably selling Mars Bars and rock cakes.) To fulfill the first part of the deal, I propose planting a fingerpost on the top of Husband Hill with the following on it: 8176 km to Viking1, bearing 72 deg 9001 km to Pathfinder, bearing 75 deg 2235 km to Mars3, bearing 148 deg 8216 km to Mars6, bearing 159 deg 9670 km to Opportunity, bearing 176 deg 3656 km to MPL, bearing 182 deg 5793 km to Mars2, bearing 219 deg 5215 km to Beagle2, bearing 282 deg 4302 km to Viking2, bearing 332 deg ...With my serious head on, looking at that list I count a mere 50% success rate.  And that's a whole lot of untouched planet. Heck, the nearest non-MER human artifact to Spirit is currently Mars3, a 1400 mile walk away to the SE. I wonder if it did land upside down or not..? And what would it look like after 34 years on the surface? Andy G  Andy: By the time The Powers That Be grant you Planning Permission (say, about 2074, if you get your application in before noon yestersol) you'll need to change Opportunity's bearing by, oooh, let's say 12 degrees - and Spirit will be 241 miles away, too...

QUOTE (djellison @ Aug 30 2005, 02:37 PM) Are those accurate bearings? Yes, they're great circles' bearings (so they often feel a bit weird if you check them against a flat map), and they should be accurate to within a degree or two. The distances might be out by a few kms, though - my Reference Martian Areophysical Geoid was <ahem>: r=3390 km ;-) Andy G |

Bob Shaw If only they could! Any data on MSL's likely driving distance? All I can see is an expected duration of 1 Mars year...not a word on range or metres/sol. Andy G |

MSL is expected to do 10 km. in its lifetime....
Like MER was to live for 3 months.... so, fasten your seatbelts! I think it can do 1 km. per sol. |

The range per sol of MSL has been greatly reduced - it's down in the MER range. Bruce will be able to tell you more. Doug |

Oh, a Purgatory effect?
Of course it pretty much depends on where you land. At Meridiani 1 km per day seems quite likely to me if you have the wheels to get over those dunes. |

If it was I was not thinking on any kind of Purgatory...I was just exagerating and imagining MSL circumnavegating Mars several times...

Really, though, the great success of the MER rovers is going to put a lot of pressure on MSL. It looked good back in the day when they could say for $800m you get two solar-powered rovers each doing 600m over a 90 day lifespan and then a multi-billion nuclear-powered rover that would do 10km over the course of a martian year. Now, the MSL's expected stats don't look so great in comparison to it's cost and what it's predecessors have already done (not to mention what they may yet manage). Of course it will be a superior platform and do a lot more useful work but the public 'perception' will be poor, especially if it -only- reaches it's designated lifespan or a little more.

A 360 degree panoramic view from the summit of Husband Hill.
The Dustdevil is hard to see. Disappeared almost complete in the overlap. Taken with the L0 Navcam on Sol 589. jvandriel

Thanks to MMB, I noticed some particles moving around between two MI images of the Mossbauer impression from sol 588. It looks like more evidence of decently strong winds up on the top of the hill.

Hi Ustrax, Sorry, no I was just wondering why 'they' had reduced an already not too impressive 10 km. range. (The remark from Doug). I think circumnavigating Mars must wait for the first Blimp! balloon on Mars |

At Meridiani 1 km per day seems quite likely to me if you have the wheels to get over those dunes. Isn't the MSL larger than the MERs? It might be able to straddle the dune if it's large enough - at least two wheels on better terrain. If I recall the specs of the MER, they say that just one wheel (given enough friction) would be capable of pulling the rover along. I'd hope something heavy too would pack the dirt down considerably. |

Thanks Cugel !
Here is another useful "Mars Balloon" link that gives you the inside story of the 1st baloon efforts between CNES (French space Agency)... and the Planetary Society in the US (Dr. Jacques Blamont was on both sides !). All preliminary drawings are there too...Finally this ended up in the Venus baloons as 1st flyers in another planetary atmosphere than Earth ! http://home.earthlink.net/~rcfriend/mars-33.htm QUOTE (Cugel @ Aug 30 2005, 07:58 PM) Hi Ustrax,
