Victoria ahead..., Time spent at Emma Dean Options

[Stu]

Might I humbly suggest this new thread, as Victoria looms large before us..?

GREAT images guys. I was out last night and have only just got online, to find Victoria opening up ahead of us... what a fantastic time!

[climber]

I agree for this new thread since it'll last only what, 1?,2?,5?, 10? more sols

[Guest_Bobby_*]

It will last 3 more sols before we discover Ustrax having a party in Victoria (abyss).

[ustrax]

Why are you taking so long?...

[climber]

(good ) question : Knowing the height of the cameras on the mast and the distance to the rim, what will be the distance from where we'll be sure to see the far rim?

[djellison]

Well - for that we'd need to know the height of the far rim w.r.t. the near rim

It'll work the other way around - once we see the far rim we'll know, from the distance to the near rim and height of the pancam mast - the height of the far rim :0

If I'm right, then going from everyone's excellent images so far these are POSSIBLY the features we'll see out across the crater when Oppy reaches the north rim...

Opposite features

Some suggested working names just to aid the pre-arrival discussion; as a non-geologist I'm keen to get some advice on what we're going to be looking at over yonder.

1. "Cleft"
2. "Tongue Outcrop"
3. north rim of "Sofi Crater" (as someone unofficially christened it in a lost-in-the-mists-of-time thread
4. "Mini Boat Ramp"
5. "The Streak"
6. "Overhang #1"
7. "Overhang #2"
8. "Shelf #1"
9. "Shelf Peak"
10. "Shelf #2"
11. "Overhang #3"
12. "Shelf #2 Peak"

Humour me, ok?

I used to think that the rim of this huge crater would be pushed up so much that Oppy would have a hard time even looking into Victoria. But, now I'm thinking that she'll easily be able to look inside wherever she wants.

The above picture corresponds to the South rim. You can recognize it easily by the small crater close to the mini-boat ramp.

Yep, that's what I said... what we'll see opposite when Oppy reaches the north rim...

[Stu]

okay, I'll just talk to myself then...

Just "Are we there yet??" time killing speculation, but I'm wondering if the "streak" on my picture above ("5")might be the trail of a small dust devil? It seems to peter out before reaching the crater floor... or it might be, as my gut instincts tell me, material spilled and slipped down the crater wall, as there appears to be slumping at "4" on its upper end. Either way will be interesting to see if this feature is still there when we get our first look across the crater, as some time has passed between the image being taken and Oppy's arrival, and some dust must've moved around in there during that period.

Also wondering - as someone else has on another thread - if the bright "line" visible to the left of Pancam images of Victoria might be the raised rim of "Sofi" crater. If it is that would mean the taller, more detailed feature might be what I've called "Overhang #1". This looks like a good candidate for some detail in the crater wall, perhaps a crumbling outcrop or exposed blocks, perhaps..?

(testing)



This might spur on some discussion about farside features...

[climber]

Thanks Stu, that helps and even more if Oppy make another move before the week-end

Looking at the new images at exploratorium I am not longer sure if we actually do see the opposite rim
and not the plains beyond ... (?)

And is the bright feature at the left side of this image the "true" beacon ?

what exciting times !
this is a childhood dream come true: taking part as life spectator in the exploration of another planet

[Pando]

Nirgal, we do see the plains, but the very bright line that is now starting to appear at the right side of this image is the far rim.
