QUOTE (ugordan @ Dec 6 2011, 04:07 PM)  My take on Boesmanskop, L456: looking at that picture makes me wonder how all the dust on opportunity's sundial affects colourization. doesn't the dust obscure the colour swatches? is it still possible to make accurate colour information from the cams/filters when the sundial is obscured? nonetheless, nice pics. |

I think dust on the lens is a bigger problem.

Ugordon,
Looking at that image makes me feel like my glasses have been smudged by a three year old with peanut butter hands! We need a zephyr or some other directional wind to come along at the rim of that massive crater! (or a four minute rain storm!) Nice work! -------------------- CLA CLL

Added some more sections to the "Saddleback" mosaic. The image is too big to post here, so I'll invite you over to my blog where I've posted it...

"Squyres and Arvidson... are scheduled to announce the details of the Homestake discovery at the AGU fall meeting in San Francisco next Wednesday, December 7. An update will be posted once the embargo is lifted." Haven't seen anything yet--but don't know where I should be looking? -------------------- Floyd

Squyres: referring to Homestake and the gypsum found -
(paraphrasing) 'This is the single, most powerful piece of evidence found by Opportunity for water.' Time for a drink

Gypsum is too soft, surely. Hardness 2. How would it stand up to erosion in this way?

Gypsum? Calcium sulfate? Works for me, and it meshes with the geochem very well. Wishful thinking wanted calcium carbonate, but CaSO4 is a puzzle piece that fits the slot nicely.
Now to find a transcript and not a webcast... --Bill -------------------- |
