Didn't they identify olivine in the material sprinkeld onto the microscope? And the material can appear green


It is posible that the olivine is in this layer to .

I didn't hear that they *confirmed* olivine, just that some of the particles *looked like* and therefore very well could be olivine.

Sol 26 look:



Merged subframe at full color with full frame at 1/4 res color and single red full res frame. Lander shadow moved quite a bit causing discontinuities.

Mods - move this if you want it somewhere else...

I took my circular version of the panorama, posted earlier, and laid it over Tim Parker's map at the best estimate location.

Then I used sight lines to hills to see which features we see on the horizon. The common features are labelled below.

That puts the site about here, to put it in context.

I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

Can't wait for them to start digging deeper. Any ideas on how deep they would like to go?
The layering in the trench should be interesting if they are able to dig deep.
I hope everyone is receiving twitters from the lander. Soon to be ranked 7th on the twitterholic page. Number 4 seems doable smile.gif

That's an easy one. cool.gif They surely would want to dig as deeply as possible, as that would likely provide the longest line of geological/climatalogical history at this location. But then we would want to study that vertical section in context, requiring additional lateral excavations.

I get the impression that the concern here is about a shallow ice table that might prevent digging deeply, thus the earlier suggestion that Phoenix might need to strip mine the national parks, to at least expose the topography of this local ice table. I suspect deeply-digging might be easier near the polygon boundaries, but I am not sure how those boundaries align with the digging degrees of freedom of the robotic arm. I can't wait to see what Phoenix does next...

Ok, this brings up a question I've had for a while now which I may as well ask at the risk of sounding like an ignoramus. unsure.gif Do we know how deep this ice layer should be? Do we have MEX or MRO data from their radars about this? I know there were press releases from MRO (I think) that showed an image produced by SHARAD of the north polar region, but it didn't really elaborate on what we were seeing.

Anyone have any more insight into this?

Yes, what's with no images received on sol 27?

I somehow missed that bit. It seems that after a near-perfect landing at a perfect location they've been having quite a bit of trouble ever so often, regardless be it with orbital or ground assets. Hope it's just a pesky cosmic ray hit this time.
