Opportunity is not quite at Victoria yet, but on the horizon is a tantalising goal for the future- the big eroded crater to the south-east, the rim of which is already visible. This is the first 'large scale' topography of the mission so far. Wouldn't it be great if Opportunity could get to these hills and uncover their secrets?

I agree that exploring the West Rim of Big Crater would be absolutely amazing, but having seen the first glimpse of Victoria I think that we are going to be here for a very long time. There looks to be enough geology here at VC to keep Opportunity occupied for a year (Earth or Martian!) or more.

Actually, the "Leg B of the etched terrain" might be feasible unless Oppy gets bogged down in Victoria. That would get us stratigraphically lower and would make for good science but not photo-ops.

Really nice picture by the way, not sure that I'd seen this one before.

Could those be fossil shorelines in the interior of that big crater? Bearing in mind how wet it's been in Meridiani, I find that easily conceivable.

Prior to committing to a Big Crater campaign, however, I'd want to fill-in the imagery to the southwest. Seems like I recall seeing some interesting dendritic channel terrain off in that direction, as well as some unique topography. The driving conditions off towards Big Crater look pretty boring.

For the love of god don't let a rover driver see this or we'll be attempting to jump Victoria in the rush to get there smile.gif

It's based on a THEMIS mosaic I found on the forums, can't remember who made it but thanks whoever you are!

I think the thing to do is to plaster the terrain between Victoria and 'Big Crater' with HIRISE images to determine the most suitable route.

That horizon looks like the one I posted in the mosaic with the synthetic sky...do not rely on the accuracy too much except for the obvious hills marking the rim of the far crater.

The real horizon is more straight and I'm not sure about 'B' ...

Maybe I'll give that horizon another go but honestly, for the moment, I don't give a rat's a** what's beyond Victoria, it's been a long way and I want to see this crater inside out biggrin.gif

Yes, the original image was yours Nico smile.gif

When we'll be on this promontory on the left, we'll have another perspective of "Troy" from which you'll be able to play around and find new/ confirm structures. I'm sure, we'll have to think about what's behind the horizon once Oppy will be inside VC. I'm sure will get bored sometimes during VC exploration so we'll revive this thread. cool.gif

So that's what the horizon feature is. I didn't believe it could be that clear from so far away, but it is. Far out.

Since it is so clear, is there any remote science we can do on it from this far away? Would mini-TES tell us anything useful? 'Cause I reckon it's going to be a long time before we get much closer. I think we will be at Victoria for at least a year (Earth or Mars). If Oppy lives forever, maybe we will someday see 'Troy' up close.

It would indeed be nice to be able to explore that crater, but we need to remember the condition of the rover at present, the fact that it's way "out of waranty" at this time, and that it will likely take the better part of a year to explore Victoria in sufficient detail.

It is the project's policy to name craters only as we visit them, and the names used are project-specific - not IAU approved. That crater is 22 kilometers in diameter, and based on the IAU convention for naming craters on Mars would be named after a city on Earth with a population under 100,000. Craters greater than 100 kilometers in diameter are named after famous scientists, at least 3 years after their passing.

The view, though, is quite glorious from here! Wait until we get to the rim!

planetarily,
-Tim.

So...Victoria shouldn't bear a city's name?
Troy was a city...Wasn't it?... rolleyes.gif
And yes...Reaching one of the promontories it will be a hell of a view we will be previliged to contemplate...

EDITED: Just called it Troy because, at this distance, it would be a mythical battle to get there and to find a tricky way for our horse to penetrate the "city's walls" and contemplate Helen's beauty...
Well...Just foreseing all of us departing Greece and sailing all the way there. smile.gif

So, "UMSF" will be OK : it's a city under 100,000
