I think the white material in 2P173771793EL5M1 and 2P173772408EL2M1 most interesting. Aren't these from the area recently traversed by Spirit and where the soil was so firm that the wheels left no tracks? This would point to the presence of some kind of hard cementing agent, either carbonate or sulphate by the brightness. I hope they took mini-TES and APX readings.

2P173502423EL5M1 shows how hard the surface is that the rover traversed over. This area to me seems to be either newly formed or windswept - all fine grain material removed from the surface. At meridian the rover tracks are giving up some of the blueberry’s (the blueberries are more grayish color than they are blue) secrets, where did the blueberries go after the rover moved over the surface. The tracks seem very smooth. I enlarged a section of 1P173546131EL5M1 image and changed the Hue while oversaturated it to come up with this. You can see some of the buried Blueberries. How hard are the blueberries? Does the blueberries pigment add to the discoloration of the tracks??? <div class="Discussion_UserSignature"> Ron Bennett </div>

You guys HAVE to see this. True color images direct from Cornell. http://marswatch.astro.cornell.edu/pancam_instrument/true_color.html

"You guys HAVE to see this. True color images direct from Cornell." I found it interesting to read the following quote from that site: "It's important to point out that this is only an estimate of the true color of each of these scenes from Mars. As mentioned above, everyone perceives color differently, and different computer monitors and printers display color differently. The colors also vary with time of day, and even from day to day because of different amounts of dust and clouds in the Mars atmosphere. And there are also sometimes small calibration problems with the images that can cause errors in the true color calculations. We've done the best job that we can to estimate the colors. Ultimately, the true test of color success will probably have to await the judgment of the real experts: the first astronauts who go there and see the place for themselves sometime in the next few decades..." Personally, I find these images rather washed out with a little too much contrast removed, but as they said, we probably won't know for sure until actual humans get there. Anyway, here is an image from Spirit, Sol 535 (L4, L5 & L6 filters): <div class="Discussion_UserSignature"> ------------------------------------------------------------------- "I hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical. Unsuccessful rebellions, indeed, generally establish the encroachments on the rights of the people which have produced them. An observation of this truth should render honest republican governors so mild in their punishment of rebellions as not to discourage them too much. It is a medicine necessary for the sound health of government."Thomas Jefferson </div>

As pointed by dedicated imager slintedin the Unmannedspaceflight forum, there is now a Cornell page dedicated to true colour imaging from MER data. Should be perfect for reference, although from the little I looked you guys here are mostly spot on with your colors ! Edit: Apologies, centsworth_II had posted this link already in the "Re: Martian sky is BLUE, tell NASA!" thread. 2nd Edit: His Idiocy TheChemist speaking : More apologies, jaredgalen had provided this link a couple of posts above, duh <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> I feel better than James Brown. </div>

"Should be perfect for reference, although from the little I looked you guys here are mostly spot on with your colors !" Thanks for the support, Chemist. I am always open to opportunities to study images produced by people who actually know what they're doing <img src="/images/icons/smile.gif" />. They do indeed make good references. I copied several really good ones for further study and will likely be tweaking my process. And thanks to you and centsworth_II for the links. <img src="/images/icons/cool.gif" /> <div class="Discussion_UserSignature"> ------------------------------------------------------------------- "I hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical.

Thanks for the Link, looks like these folks took more of an analytical approach to it. As Cornel admitted and swamcat shown the real test will be when we send Humans to Mars. The Vikings which was radio to analog shows a slightly orange hue to the surface material. Parts of the rover as seen on Earth and as shown in some of their images don’t quite match up color-wise. All in all It does show that we are on the right track. We all agree that the sky at the horizon isn't blue. <div class="Discussion_UserSignature"> Ron Bennett </div>
