Blue Flowers of Mars

bobvanx · Oct 3, 2004

extrasense, As I review these flower and statues threads, I notice that they concern the investigation of extra-terrestrial life. So you should consider getting one of the moderators to move them to the SETI forum. Space science and astronomy should deal with rocks, nebulae, stars, and planets. In my opinion

<<do you mean an actual creation of a living organism(s) or just something that resembles a flower? >> If it looks like a flower, smells like a flower, has a shadow of a flower - it must be a flower <img src="/images/icons/smile.gif" />

smell? no, just a pure speculation <img src="/images/icons/smile.gif" />

smell? no, just a pure speculation Just like the rest of your "theory".

Unfortunatly there has been funnier

spacechump · Oct 3, 2004

Well no wonder extra thinks the rock is blue. He's looking at an unadjusted false color image of it that was made using a combination of the L2, L5 and L7 filters. But even adjusting these color values doesn't give a true sense of what the eyes see because L2 is near infrared and L7 is deep violet. http://marsrovers.jpl.nasa.gov/gallery/all/2/p/111/2P136234390EFF3600P2401L2M1.JPG http://marsrovers.jpl.nasa.gov/gallery/all/2/p/111/2P136234439EFF3600P2401L5M1.JPG http://marsrovers.jpl.nasa.gov/gallery/all/2/p/111/2P136234337EFF3600P2401L7M1.JPG plus look at this image which shows what looks like an uneven plane break...comparing images and shadows. http://marsrovers.jpl.nasa.gov/gallery/all/2/n/111/2N136235187EFF3600P1833R0M1.JPG

Here is where color image was taken from: http://mars.gh.wh.uni-dortmund.de/mer/spirit/111/tn/2P136234439EFF3600P2401L5M1_L2L5L5L7L7.jpg.html There are hundreds of color images at that site, made using the same software and algorithms: http://mars.gh.wh.uni-dortmund.de/mer If you really think you have better ideas as to recreation of colors, you should write to them with your suggestions. This way if you are right, it will benefit a lot of people who like me are relying in that site for colors. ES

Folks here's the website that extra is pointing to: http://mars-news.de/ Extra. Please read about the pamcam k? http://www.highmars.org/niac/education/mer/mer00b.html http://www.highmars.org/niac/education/mer/mer00.html http://www.highmars.org/niac/education/mer/mer00e.html

If you really think you have better ideas as to recreation of colors, you should write to them with your suggestions. This You might what to try these sites. The first one is the best explanation I’ve seen for how the pancam works. If you want the most realistic color renditions your best bet is JPL’s website. It’s their equipment so one would think they would know it the best. Cornell’s mars website is also a good source for the same reason. The source that you are sighting looks like something that was put together by a student at Dortmund. A student who didn’t have any clue what he was doing. http://www.abovetopsecret.com/forum/thread30048/pg1 http://athena.cornell.edu/

I think that person is not trying to suggest that their colors are accurate. Here's an interesting set from an early sol http://mars.gh.wh.uni-dortmund.de/mer/spirit/009/ What I find very interesting is their solution to getting the colors from filters that aren't really designed for color reproduction. By summing L2 and L3, as well as L6 and L7, they get much closer than I would have expected. Look at the sundial target, and see how different it looks when the image is built up of various filter combos. Unfortunately for the "blueness" of the rock that looks like a flower, the filters used to build that image aren't the ones that lend themselves to accurate color. Oh, well, but it was a valiant effort to bring some science into the discussion! Keep it up!

extrasense · Oct 3, 2004

The thing is that actual color is not that importent for discussion of "flower". The shadows are. In this partucular set of raw images, there is not enough data to reliably recreate colors. We could argue forever, but the reality remains that we don't know. I go along with the guess, that seems good enough to me. ES

spacechump · Oct 3, 2004

What do you mean not enough data? We can look at the REST of the rocks (they are the same color under the false image filter combo). Other images have been taken with L4, L5 and L6 and none show blue rocks (unless you use the raw saturated data). We have examples of rocks from every mission to land on Mars. Every probe has touched a rock or ground into a rock or examined its makeup. We know the color of these from past missions. But we have never seen a flower. We know the environment creates an extremely low probabilility for finding such a thing. We have not seen one or examined it. For you to think you're right on the suggestion of faith doesn't make it right....because we have evidence that heavily weighs against your idea. You do not know what science or theories are let alone for you to think you can pompously define them.

<<What in those shadows indicates that these are flowers? >> http://mywebpages.comcast.net/mycommon/Apple--Mars-Flower--Cristal-mod.jpg The apple has solid dark side, while the martian flower does not. Compare it to the dandelion, which also does not have solid dark side. http://mywebpages.comcast.net/mycommon/dandelion.jpg

spacechump · Oct 4, 2004

Phaw....the shadow is there is behind the curved weathered part of the rock. You just WANT it to be a flower although there is no resemblance.

extrasense · Oct 4, 2004

Listen, could you explain to me why everybody is talking about a single "right" colors. There should be considered two kinds of "right" color images, representing: (1) the way objects look to the observer who is on Mars (2) the way objects look if brought on Earth, to the observer who is on Earth The (2) is ok for geologist, the (1) - for the rest of us ES

spacechump · Oct 4, 2004

(1) the way objects look to the observer who is on Mars And we're saying it ISN'T BLUE. Near-infrared and near violet were used instead of red and blue. JPL does this to see differences in mineral content in...guess what...rocks! The (2) is ok for geologist, the (1) - for the rest of us Only if you crave ignorance which in this case you have been displaying....just like on every other forum you spam with your junk.

spacechump · Oct 4, 2004

Also while I'm grilling you, look at the placement of the sun in that image and look at the shadow. The shadow is to the left and behind the rock. Why is it not uniform? Because the rock isn't uniform! Unlike the apple that is a sphere! Come on extra this isn't hard stuff to grasp unless you know what "answer" you want.

extrasense · Oct 4, 2004

<<Did you create those pdfs or find them?>> Which pdfs, do you mean jpegs?

kelle · Oct 4, 2004

Wow, I have an image of a rock!! Look, it has a shadow on itself, it must be a rock!!: image

Another flower : link <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> I feel better than James Brown. </div>

extrasense · Oct 5, 2004

I have found another blue flower too <img src="/images/icons/smile.gif" /> http://mywebpages.comcast.net/mycommon/2p221-2P145980752EFF8500P2284L5M1-hairy-flower2-color.jpg

I know I was gone a LONG time, but I don't remember the SETI forum being THIS STUPID. Was it really THIS bad in here before the crash? <div class="Discussion_UserSignature"> Note to Dr. Henry: The testosterone shots are working! </div>

jpking · Oct 5, 2004

I found something better than a flower on the mars rock pile, it's the head of a dog; no wait, the color is a little off, that's probably because it's just a rock, just like all the other objects in the picture.

pizzaguy · Oct 5, 2004

DOes that look like a head of a dog to ANYONE here? <div class="Discussion_UserSignature"> Note to Dr. Henry: The testosterone shots are working! </div>
