I think these views are easily the most dramatic from Oppy since she was aside Burns Cliff way back in December 2004.

You've come a long way, baby!

Fantastic James! I can't wait until Opportunity gets a chance to 'touch' the wall.

Here's my artist's view of this iconic mission image.

I'm looking for a place to post the 19mb version. smile.gif
Enjoy

Alright you two, stop it, just STOP it! How are we meant to get any work done when you create masterpieces like that?! I've three big editing jobs on the go, talks to arrange, and then my day job to go to later, and you serve me up THAT to wander around and drool over!!! I can't stop scrolling around it, looking at all those lovely layers and beautiful boulders... Cruelty beyond measure! cool.gif

Will we have a chance at some point of seeing the cliff face out of shadow? It is a magnificent panorama, but the lighting isn't exactly optimal.

Thx to all image contributors!

The cliff faces almost due south, so at this time of year (southern midwinter) it is essentially permanently shadowed. Oppy would have to wait for summer to get a non shadowed shot and I think we'll be long gone by then.

Could there be an advantage in being in shadow? A more even illumination will play down the topography of the rock surface for sure, but that could make it easier to observe other features such as differences in colour and grain size.

From this new update:
QUOTE
With each move closer to Cape Verde, power to Opportunity's solar arrays has decreased as more of the promontory obscures the sky... The rover's next short advance toward the cliff will tilt its solar panels away from the Sun, limiting the amount of solar energy even more. Rover drivers will take great care to ensure that Opportunity stays out of the shadow cast by Cape Verde, which currently extends approximately 3 meters (about 10 feet) from the cliff face.

As spring approaches, we'll be able to get closer to the cliff, but that will be a very slow process...

As far as imaging the cliff in full shadow, they did this very late in the afternoon on sols 1579 and 1580, using the open L1 filter setting to let in as much light as possible. Some of these shots show incredible detail:

Stunning photo James - I think it's about time Mr Squyres had a feature named after him as he has got to be the king of Mars Geology
how about a vote for 'Squyres Cliff' - a fitting tribute to SS & team

As my understanding is - the shadow of the cliff (and therefore low solar energy) will prevent Oppy from doing lots of interesting work with its IDD ??
Other problems could also prevent it - unpassable terrain for example. How good are the chances to reach the cliff ?

From the latest update:
QUOTE
Next week's plans call for Opportunity to bump forward to a point only a few meters away from the cliff face to take high-resolution images. If possible, Opportunity will also conduct scientific studies of an outcrop target called "Nevada" (so named because of a rock next to it which has a shape reminiscent of the outline of the state of Nevada) using instruments on the robotic arm.


Anyone hazard a guess as to which rock is Nevada?

blink.gif Astro0, your image is just incredible and so beautiful !!!
Well... I'm so sorry to arrive "after the battle" with only a black & white Navcam (calibrated and cleaned) version...
Anyway... I hope you will enjoy it ! smile.gif

Yeah...been looking at that one for awhile, now. If I found that on Earth, first things I would think of are 1) gypsum crystal, 2) aragonite, 3) sand-encrusted exotic silicate, like kunzite. The truth is probably far more mundane, but if it is in fact any of these minerals then there had to be considerable water present to form it at all way back when.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I was wondering if it wasn't the bedrock closer in here:

Right shape, but I guess a bit close in
